STRUCTURE:BODY

After completion of a recall fix by the dealer for the grill while driving the front grill deflector detached striking the front hood and top of the cab before flying behind my vehicle barely missing a following vehicle and settling alongside the road. I pulled over, inspected the front of my vehicle to assure it was safely drivable. Once I removed loose pieces I returned and retrieved the top grill from the roadside then drove directly to the dealer who completed the recall fix. They have ordered a full grill for replacement. The recall fix/repair failed within day of completion. GM Program # N242490120 Status Complete NHTSA 25V060 Date Issued: 2025-02-06 Description General Motors has decided that a defect which relates to motor vehicle safety may exist in certain 2022 model year GMC Sierra 1500 vehicles equipped with chrome front grille deflectors. One or more of the attachments that hold the front upper grille deflector in place may fracture over time. If all eight attachment points break, the deflector may detach from the vehicle while driving. Safety Risk Description If a front grille deflector detaches unexpectedly while driving, there is increased risk of a crash. Repair Description Dealers will reinforce or repair all attachment points on the chrome front grille deflector. Recall Completed 2025-08-21

Initially experienced hard clunking sound when transmission shifting between 35-40 mph. I took in for service and dealership replaced EGR sensor. The problem was not resolved with this fix. I took the vehicle back for service and the dealership then did a software/system reset. I then drove my truck with towing a trailer to San Diego and upon exiting the freeway, the back tires locked up causing a screeching of the tires which caused my vehicle to swerve. I felt as though this could have caused an accident. Shortly after, the engine light came on and my vehicle went into “limp mode”. A dealership in San Diego then told me that the valve body plate would need to be replaced. According to the internet this seems to be an ongoing issue with this year’s vehicle, yet no recall has been issued by GM. I understand GM has issues a special warranty coverage #N242454441 providing extended warranty for control valve issues. I’ve been told my VIN is not included for this special warranty when it is the exact same issue.

See attached document for complaint. I'm writing to formally express my concern and disappointment regarding the excessive delay in resolving the recall issued for my vehicle. While I understand that safety recalls can involve complex logistics, the prolonged timeframe without any clear resolution has created both an inconvenience and a safety risk for me and other vehicle owners affected by the same issue.

My motor locked up a year ago. Before the recall. At 74k miles. GM stated they did not know why it happened. Although there was 6 of the same trucks in their lot under 20k miles with the same problem. I was forced to pay out of pocket. I notified my GM dealer that my engine was knocking at 15k miles and they did nothing. Now that I have a new engine I have brought it to the dealer 3 times because it is also knocking. They’ve told me they hear it but theirs no code so nothing wrong with it….. GM refused to help me in any way nor will they help me get a reimbursement for their manufacture defective engine that I payed for. I had to take a $10k loan out to get back on the road. Every day that passes I am paying more interest because of GM. They will not even let my bring it in for an inspection and the heavier weight oil (they want me to pay diagnostic fee HA) I don’t want to take legal action but it feels like if I don’t, GM is going to ruin my life. Such a Blatant disregard for the customer. This whole thing has put me in such a terrible financial crisis I’ve been living check to check since this happened. PLEASE HELP ME.

My truck is under the national recall from GMC for the 6.2L engine problems. I even received the recall notice from GMC stating this. This truck has been in and out of the shop for engine problems things I took delivery of it in 2022. The latest was in April of 2025 and while it was in the repair service at the dealership, the national recall came out. During that time the dealership tried to tell me the problem was with my exhaust system so I was not covered under the recall. I knew they were not being truthful so I refused to take possession of the truck as I new it had all the symptoms that GMC was describing in my recall notice. My truck sat at the dealership for almost 5 months and last week they force me to take possession of my truck my taking back my "loaner vehicle". They stated "my truck passed the required inspection", which I knew they were being dishonest, but was forced to take the truck back anyway. Three days after taking possession I was on the interstate doing 60 mph and the engine totally seized up and almost caused an accident from the vehicles behind me running into me because of the sudden decrease in speed. I was able to safely pull over and had to get towed back to the dealership. This incident is beyond just a engine recall now because they new my truck was not safe to drive and forced me to take back my truck. Im just thankful I was driving and not my wife, or having my two grandchildren in the truck with me. To make mtters worse in this scenerio, this truck is actually my replacement truck because my 2021 truck had to be taken back per the Lemon Law in 2022, so this will now be truck #2 being Lemon Law and my original truck loan isnt even paid off. I have all of the various engine repair paperwork on this truck dating back to 2022.

STRUCTURE:BODY

Recall Number N242490120 was performed in April 2025 at: Rivard Buick GMC, Tampa, Florida, Phone # 813-620-6500 The Grille was inspected and repaired with adhesive to reinforce the plastic tabs to the grille so it would not detach and cause a safety issue when driving. This recall was performed before we purchased the vehicle and we are located in Oklahoma City, OK. The vehicle has been listed for sale at our car dealership in Oklahoma City and had to have multiple Warranty Repairs at GMC/Chevy over the summer. We Sold the vehicle on [XXX] to a customer: [XXX] and he was driving the vehicle and the Grille detached and fell off the vehicle while driving. The Grille hit his hood and windshield and caused damage. He could have had an accident when the grille detached from the front of the vehicle. We dropped the vehicle off at Bob Howard GMC on 8/26/25 and they said since the recall has been performed that it is not covered and nothing they can do about fixing it under Recall or Warranty. We reached out to GMC Customer Service 1800 # and they told us the same thing, and we would have to repair it out of pocket. I find this extremely unprofessional and avoiding taking care of the issue that should have been taken care of the first time. The part is faulty and part of the Recall to be repaired or replaced properly so this hazardous part does not cause a problem while driving and that is exactly what happened even after having the recall taken care of at GMC. We at La Raza Motors Inc. have inspected the vehicle/Grille and upon discovering the previous recall/repair that was performed at Rivard Buick GMC in Tampa, Florida, the Grille was not properly repaired and not up to standard. This part should have been replaced instead of repaired. [XXX] retrieved the broken/detached Grille after it detached to see what had happened and we have pictures. No police report was made at the time of the incident. No lights or warnings were on at the time of the incident. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT

ENGINE

The vehicle’s shift control module in the transmission is malfunctioning. The vehicle is shifting hard and having trouble finding the gears. The safety issue is that this is a known GMC transmission malfunction with the risk that the rear wheels can lock up when downshifting in the higher gears. Sudden rear wheels lock up proses a risk to cause an accident on the roadway potentially harming the driver and passengers in the defective vehicle as well as risking other drivers on the road. No warnings were given before the malfunction. The vehicle has been regularly serviced on time and taken care of. The malfunction began and within one week the vehicle progressed to shifting so hard I didn’t feel comfortable driving it especially with my child in tow.

As I was taking the on-ramp to enter traffic, My GMC started shifted very hard and losing power. The vehicle was sputtering and making strange sounds. I was unable to exceed 60mph due to excessive vibrations/shaking the vehicle. Steering was starting to be difficult at the same time I noticed Oil Pressure Gauge slowly dropping on instrument panel below 25psi. I had to pull over immediately. oil pressure remained lower than normal, verified Oil was filled to manufactures specifications (changed June 30, 2025). Returned the vehicle to my place of residence as safe and slow as I possibly could and parked it as it is a major safety concern.

Purchase a used 2022 GMC Sierra 1500 Denali with a 3.0L diesel at around 42,000 miles. Drove it for about 1,500 miles before I started noticing unusual shifting with the transmission which became more noticeable with time. At around 44,000 miles, the truck had two hard shifts going 35-40 MPH on a flat round and put itself into limp mode. Turned off and on the truck multiple times, the engine light always stayed on but the symptoms would come and go. Either way the truck always went back into limp mode after a few miles. I did a quick scan and it came out with a P0700 and P0746 code. I limped it to the dealer and was told that it was a bad valve body which is apparently on back order with no ETA and they can’t tell me when I will get my truck back.

Pulling away from a stop sign when we were driving, and when I started to excelerate the truck it just died. We were at a busy intersection and was able to pull off the road into a parking lot and had AAA come and tow the truck and took it to Poages Auto Plaza, Quincy IL. This could have been really serious had we been on a busier road. We tried to restart the vehical and it would not start. We are going to need a loaner vehical preferrably a Truck.

While driving on [XXX] from Houston to San Antonio the front Grille spontaneously flew off from my hood and hit my windshield. Grille damaged the hood but no known damage to shield. This was very frightening while on a highway because it almost caused me to crash as it triggered my PTSD from the blast and led me to swerve. Fortunately I regained vehicle control and avoided other damage to others. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

STRUCTURE:BODY

Multiple times today my tailgate dropped randomly without my knowledge. With the tailgate randomly dropping, and no warning lamps, messages, or other symptoms, it puts others at risk due to the potential for the contents of the truck bed to fall out into traffic causing damage or bodily injury to others on the road. During my research on what could cause this to occur, I was made aware of a recall of this same make, model, and year vehicle. The description of the reason for the recall was exactly what I experienced with my vehicle. I immediately attempted to confirm that my vehicle was listed on the recall by entering by VIN online. I discovered that there was not an active recall on my specific vehicle, so I contacted the nearest GMC dealership. After speaking with the service tech, he confirmed that my symptoms was exactly what the dealership had addressed with other vehicles that were on the recall list. He confirmed that my VIN was not included, yet the recall did have the same make, model, and year. I will be making an appointment at my dealership to repair this at my expense since it is not covered on the recall.

POWER TRAIN

While traveling at highway speeds in a very congested and busy segment near Virginia Beach Virginia the truck began shifting erratically and suddenly lost power which required me to cross two lanes of traffic 30 miles an hour below the speed limit to get to the shoulder. Cars were swerving everywhere to miss us with this sudden loss of power and speed. The truck has been towed and now at the dealer where it has been diagnosed with a stuck/failed pressure control solenoid and the valve body must be replaced which is apparently on back order due to the high number of failures on the GM 10speed transmissions. Such a sudden loss of power and the reduced power mode of the software made the situation extremely dangerous at highway speeds in congested traffic. Something should be done quickly to get these vehicles off the road until a suitable fix is resolved as someone is going to get killed.

I bought the truck 3.5 months ago with 66,000 miles with a recall (reprogramming) on the transmission already done according to the dealer. Then yesterday on 6/25 the truck stuttered then shifted hard. When I got to my destination it didn’t have reverse. But no warning lights. So I drove it to the dealer and before I got there it did it again and sent the truck into a power loss mode this time with a warning light. And would barely finish going up the hill with cars behind me. Now they are saying it needs a transmission but gm is only offering to pay half. Also saying the diesel would be covered but my gas isn’t even though I’m pretty sure they are the same transmission makes no sense. Lastly shouldn’t them offering to pay %50 show that they know they have a problem

Due to GMC not having a fix for the safety recall to repair the potential engine failure, we are unsafe driving our car. This has been in effect since April and still no fix is available. We feel extremely unsafe driving this car due to this issue.

The OnStar module is no longer working. When I purchased the vehicle, the green light did not turn on. I called customer service, and they advised me to take it to the dealership since they were unable to connect to the vehicle. I am unable to contact emergency services in case of an accident, and I cannot access services like remote location and remote start from the mygmc app. I have seen several people online state that their module failed as well. It's a common occurrence that falls onto the customer to pay for. An update to the module seems to be the reason so many modules are failing.

I was on the way to the airport and my vehicle suddenly went into reduced power mode and had trouble shifting into gear. I pulled over, shut off my truck, and turned it back on only to have the problem continue. I was able to turn around and make it home, but the vehicle would then not shift into reverse. We had to push the vehicle so that I could position it in the street. Once we were back from vacation, I took it to a GM Certified Service location (my local Cadillac dealership). After review, they diagnosed a defective valve body and the engine recall. I’ve been informed as of today that my valve body will be $3,000 and GM will not cover it because I have more than 60k miles on the truck (it has 72k). After research, this is a common issue and it is ridiculous that GM will not escalate the issue and help consumers with this clear problem due to their manufacturing and/or design. The vehicle is currently sitting at the dealer waiting for a back ordered valve body and I have had to go out of pocket to rent a vehicle. Every service for the vehicle has been completed at a GM Certified Service location. It is available for inspection immediately, if required.

The incident occurred during a journey from Sacramento, CA, to Winchester, CA, a distance of approximately 486 miles in my 2022 GMC Sierra AT4, equipped with the recalled 6.2L V8 engine, which has accumulated around 61,000 miles. I was driving when a loud bang caught my attention over the music. After that, I heard swooshing sounds three times before the engine lost power. I was able to move over to the right shoulder throughout heavy traffic; I managed to make it safely. During the maneuvering of my truck to the shoulder, I noticed on the dashboard that the vehicle was telling me to shift the vehicle to neutral and start it. I shifted the vehicle to neutral, but it did not start. Upon inspecting the fuses and battery for any obvious issues, I proceeded to check the harmonic balancer for signs of engine seizing. The engine had completely locked up.

I am writing to formally lodge a complaint and request immediate resolution regarding my 2022 GMC Sierra 1500 equipped with the L87 6.2L V8 engine, which has been out of service for more than 30 consecutive days due to a recall-related defect. The vehicle is inoperable, and I have been informed by the authorized dealership that no loaner vehicle will be provided, with no clear estimate for when parts or repairs will be available. I have contacted both General Motors Customer Assistance and the local dealership to request a loaner vehicle. In both cases, I was informed that no loaner was available. I was advised that I could rent a vehicle at my own expense, and that GM would only consider reimbursement up to $44 per day, but only after the recall is completed and only if my case is deemed eligible upon review. This reimbursement policy—requiring me to first pay out-of-pocket without guarantee of repayment—has placed significant undue hardship, financial burden, and emotional stress on me and my family. This situation is especially frustrating considering the vehicle: Remains under GM’s lifetime powertrain warranty; Has been completely unusable for 59 days without replacement; Has left me with no reliable means of transportation, and Involves a known defect acknowledged by GM, yet with no definitive timeline for resolution. As a result, I am suffering direct and ongoing consequences, including: Out-of-pocket transportation costs; Disruption to daily life and mounting stress that no consumer should face after purchasing a premium, modern vehicle from a manufacturer of GM’s reputation. Accordingly, I am requesting the following: Provision of a comparable loaner vehicle immediately, or full reimbursement for a rental vehicle retroactive to the date the truck became inoperable; Compensation for loss of transportation and impact on life. If GM cannot resolve the defect in a timely manner, a full repurchase or replacement of the vehicle under federal warranty law.

While driving on the freeway, my truck suddenly experienced a severe and unexpected downshift into first gear at highway speeds. Dashboard warning lights immediately illuminated, indicating multiple system faults. I was able to safely pull over and shift the vehicle into park. However, after doing so, the truck completely refused to engage drive or any other gear. This abrupt and uncommanded downshift posed a serious safety risk, not only to myself but to other drivers, due to the potential for loss of vehicle control. The vehicle had to be towed from the scene. It has now been at the dealership for over two and a half months, with no clear timeline for repair or resolution. This incident raises major concerns about the reliability and safety of the transmission system, particularly under high-speed conditions.

The dealer is telling me there is a faulty engine coolant, flow control valve on this vehicle and multiple other people are having the same issue. The part is on backorder and takes months to arrive.

Pulling out in traffic and not being able to accelerate can be extremely dangerous.

While driving on the highway at 75mph, the engine stopped responding to the cruise control speed it was set to. The vehicle started to slowly lose speed and the shifting was not normal causing the engine to rev from below 2000 RPMs to about 3500 RPMs, at this point the engine stopped producing power, the transmission was shifted to Neutral by itself, and the check engine light illuminated. While I was able to move to the shoulder and put my hazard lights on, this could've caused an accident in a more congested area. No one was harmed or any accidents occurred. The truck would no longer start, at this point GMC ONStar was called and they provided a tow truck to the nearest GMC dealership. While waiting for the tow truck, I decided to read the codes for the check engine light, P0016 and P0011 codes were populated. The codes were provided to the dealership.

The engine locks up and leaves me stranded six hours away from home. Yes, the oil was changed religiously throughout the engine’s life, and all service was done through the dealership. I went back and forth with GM for weeks and they still refused to replace the engine on their dime. I was forced to come out of pocket 13000 dollars to replace the engine.

GM COULDN’T EVEN TELL ME WHY IT EXPLODED AND COULD NOT ASSURE ME THAT THE SAME ISSUE WOULD NOT HAPPEN TO MY REPLACEMENT ENGINE. 2nd engine started to DO THE SAME THING AFTER 8000 MILES AND THE SAME THING HAPPENED AT THE DEALERSHIP.

I pulled over immediately and turned the vehicle off. I got out checked all the fluids “all were full and good” no leaks, cracks, nothing obvious I could see. I got back in and started the engine for a moment and heard a slight knocking on the passenger side of engine and felt a little vibration not present before. After getting it towed and not wanting to risk further damage I got the vehicle to a GMC dealer who then diagnosed that I had a failed lifter on my vehicle. This caused bent rods, leading to internal engine damage and I needed a completely new engine. The odometer reading was 68,231. I have not even had a headlight go out in this vehicle yet. All of my oil change records were up to date. It was past my warranty with GMC so they would not pay for it and wanted me to pay 10,700$ out of pocket. My insurance ended up paying for it. When I inspected the engine myself with a GM mechanic he told me that they have been having ALOT of issues with these lifters being stuck causing catastrophic engine damage. Obviously the 6.2 liter is noticed but my vehicle is a 5.3 liter V8. They believe it is caused by the AFM fuel saving feature where it goes down to 4 cylinders on highway speeds to save gas.

On December 12th heading to Bozeman at 88 MPH on I-90, truck completely died at high speed. We were going to have it towed to Billion in Bozeman because this was the cheapest route. We then got notice from your dealership that we had to tow it to Billings because Billings dealership never transferred the paperwork from Canada. $825.00 later we dropped the car per towing at Billings dealership. Monday, went to dealership and there was no word as to when his truck could get fixed. I was told by GMC that we would be reimbursed for the towing expense and since you did not have a loaner vehicle the 2 options GMC provided were to rent or car, reimbursed or GMC would cover our loan payment until the truck was fixed. Every week called dealership for an update and there was no update. I ended up calling Menholt-Chevy because I wanted to know what the average wait time was for this sort of problem. He said they had engines but it would be the same engine installed and if the warranty was through GMC, GMC would have to do the work. We were hesitant to even drive with this same engine again and possibly having the same situation happen again. Menholt suggested we trade the vehicle. They came up with a trade deal through his dealership on February 10th. February 12th AJ with Menholt had the vehicle towed to their dealership, exactly 2 months later. Ali, from GMC emailed April 2 stating they can no longer re-imburse us because we did not accept any incentives that were offered through GMC and that they tried to work with us and we did not accept any of their offers. XXXX and I were never offered anything, Period. We asked dealership for proof of offers and they could not provide any. I have never been re-imbursed and have been ignored from that point forward. The dealership has misinformed GMC and GMC and the dealership misled us. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Below 10,000 miles my truck had the master brake cylinder to put which they repaired under warranty. At about 89,000 miles the engine went out stating a misfire on cylinder 2. After talking with GM the vehicle needed all the rods and cam shaft replaced which was almost an $11k repair of which I had to pay almost $5k. The truck still has sporadic shakes while at idle. Many other owners have complained of the same issues. It’s hard to understand that a new truck would have so many issues. The truck was also sold without the chip to heat the seats or the heated steering wheel. These were down afterwards one of them about a year after purchase. We feel GMC should have paid for this repair given all their engine issues. They changed the warranty from 100k miles to 60k miles because they knew these engines have major issues.

Hello, I wish to report this injury / incident with the failure of the power running boards on my 2022 GMC Sierra 1500 Denali Limited. There are no warning Lamps on the vehicle. The truck is regularly serviced and inspected. The truck recently had a multi-point inspection at the dealer. The power running boards started to come out after I opened my door, as I stepped down, the steps retracted and went back in causing me to fall hard on the ground and smash my knees. Driver and passenger sides are now acting up, even with the truck parked and locked, passenger side wants to go in and out on its own and sometimes extends to the tire. As I researched this problem, I found out that others have had similar issues with the same vehicles that have these power running boards. I removed the fuse now to prevent further injuries.

I had taken my vehicle to the dealership for a front grill assembly recall by the end of the day they called me and said I needed to leave my truck at the dealership because of a coolant control valve and they don't recommend me driving it. They told me they would get me a rental car but we're not able to get me one until 11 days after my vehicle was in the shop. I told them I needed a truck for work but was told they could only offer up to 44 dollars a day and I'd have to take a vehicle that was given to me or pay out of my own pocket to rent my own. I had the case escalated but have yet to hear anything back from GMC if they have even recieved the part or what is going on with this backorder part! From what I've been seeing and reading this is obviously an ongoing thing with GMC they have known about this coolant control valve for years now but instead of producing them so they are no longer on backorder they continue to produce plenty of new vehicles to throw on the sales lot. I am out of thousands of dollars because I don't have a truck and only 2 weeks into this mess with GMC. The vehicle is paid off and I continue to wander when a part or gmc will give me a better option. So I can continue with my business.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

The vehicle is available for inspection upon request. While utilizing Super Cruise on the interstate in stop and go traffic conditions, the vehicle will come to a complete halt and jerk (as though you I slammed on the breaks). This has happened approximately 4 times and each time, driving conditions were good and during hours of daylight. The halt is very violent and causes the vehicle behind me to slam on their breaks. The latest instance occurred on Tuesday May 29, 2025 and forced the vehicle behind me to swerve off of the road. The emergency breaking warning does not sound nor is there a reason for it to do so as it has happened when the vehicle in front of me is moving with traffic and has not slowed down or applied breaks. The super cruise system also does not disengage or say that the road information is unavailable. The vehicle simply comes to an abrupt halt, to the point where if things are in the seats they will fly forward and then the system behaves as though nothing has happened. Traveling speeds vary between 10-20 mph when it malfunctions. The problem has not been reproduced and it shouldn't because it is a serious safety hazard for the driver and other commuters on the road. I was told a module software update would fix the issue however that did not. There were no warning lights that occurred prior to any of the instances.

Engine failure requiring engine replacement. I was told it was likely a bearing failure issue. I purchased the vehicle used from grapevine Buick with about 75,000 miles and decided not to purchase an extended warranty because I have always had good life and no engine issue with my previous chevy vehicles. There were no warning engine lights before, when it occurred or after it occurred. When the problem occurred on 12/2/24 I was driving on a road going approximately 50 mph when suddenly I felt a sudden loss of power. I then pulled over into a parking lot and could hear the engine knocking and making a screeching sound. I was over 230 miles from home when this occurred and had to get the vehicle towed back home. I had it towed again to an a shop where they determined the engine needed to be replaced. There was lots of metal shavings found in the oil pain. I was told it was likely a bearing failure issue. As I had no extended warranty and the factory warranty expired at 60,000 miles I had to pay over $12,000 for the engine to be replaced on a vehicle I had just purchased the prior month.

I had complete engine failure due to rod bearing failure resulting in the engine locking up and leaving me stranded on the road in 20° weather while waiting 2 hours for a tow truck. My safety was in jeopardy when this happened due to the extreme cold and being stuck on the side of a very busy highway. There was no warning and no warning lights on the dash prior to the engine failure. The engine in my truck is the L87 which is GM’s 6.2 liter V8. Once the truck was towed to the dealership they told me it was completely locked up and the needed a complete engine replacement that took over 8 weeks. Dealership told me the seized engine would be sent back to GM so they could inspect it for causes on why the rod bearings failed resulting in the seizure of the engine.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

repeated mechanical failures of my 2022 GMC Sierra AT4, which I purchased on October 26, 2024, with approximately 37,000 miles on the odometer. The adaptive cruse control is wonderful when it works but I have found even with the sensor clean the truck will slam on brakes on its own causing me to nearly be rear ended. It happens when driving into the sun and at night. I no longer trust adaptive cruse and use manual cruse. Within just 55 days of ownership, and after driving roughly 4,700 miles, the vehicle experienced a catastrophic engine failure without warning on December 20, 2024. This failure left the truck immobilized in a highly dangerous situation—stuck in the middle of a 65-mph highway at a red light, without the ability to shift into neutral and remove the vehicle from traffic. I was forced to activate the emergency flashers and exit the vehicle, standing helplessly on the side of the road while praying that oncoming drivers would see the truck in time to avoid a potentially deadly accident. The truck was towed to the dealership the following day, December 21, 2024, where it remained for an unacceptable 110 days awaiting a replacement engine. I finally took possession of the repaired vehicle on April 10, 2025. Shockingly, only two days later—after driving just 328 miles—the vehicle suffered a second catastrophic engine failure without warning. The truck is now inoperable once again, sitting in my driveway and in need of a third engine replacement. While the odometer currently reads 42,365 miles. This ongoing situation has been not only a major inconvenience, but also a significant safety concern and financial burden. I am extremely disappointed in the reliability and performance of this vehicle. This level of failure on a vehicle that is still under powertrain warranty is simply unacceptable.

I had previously had to have the engine rebuilt due a collapsed lifter at 70,000 miles and I was concerned that the noise was a precursor to a repeat of that problem. Instead, the dealer informed me that problem was a failed connector rod bearing and would require a replacement engine. The service manager said my truck was not safe to drive since it could experience a sudden catastrophic failure on the highway.

While driving my 2022 GMC Sierra Denali 6.2L truck, it somehow turned off. I placed it on neutral and tried to turn on, but it didn’t. I maneuvered to stop at the side of the road, but I was not close enough to the curb making it uncomfortable for others to drive around. I tried again to turn on the truck, but it didn’t. Before and after everything looked good, there were no symptoms or warning lights on the truck. I gave it a break and tried to turn in the truck, but it didn’t.

They checked the truck, and found out that the battery was damaged, and an open starter fuse again. They changed, but this time they kept it on test to the next day and the starter fuse was damaged again. They found that the engine was locked, which is why the starter heats up and the amperage consumption increases, opening the fuse, the engine does not turn easily, the oil is at the correct level, it does not indicate low pressure in the initial driving test. They removed the oil pan and found metal particles in the oil and in the pan. After that they removed the rod bearings and can see that they are scratched and overheated, crankshaft scratched as well. Need order a new engine, oil cooler, oil cooler lines.

While driving my 2022 GMC Sierra Denali 6.2L truck, it somehow turned off. I placed it on neutral and tried to turn on, but it didn’t. I maneuvered to stop at the side of the road, but I was not close enough to the curb making it uncomfortable for others to drive around. I tried again to turn on the truck, but it didn’t. Before and after everything looked good, there were no symptoms or warning lights on the truck. I gave it a break and tried to turn in the truck, but it didn’t.

While driving on a busy highway, the vehicle lost all acceleration. Seconds later, the entire truck shutdown. Lucky, I was able to get into the right hand lane prior to losing complete power, which allowed me to steer the truck onto the shoulder. It appears that an investigation has been launched into vehicles equipped with the GM 6.2L V8 L87 engine. This catastrophic engine failure not only put me in a fairly unsafe situation, it is costing me $13,800 to replace the engine on a 2022 GMC Sierra Denali.

On February 18,2025 I texted the imperial valley gmc technician because started hearing a motorcycle noise like and wanted to schedule oil change. Never responded. On February 22, 2025 while driving the the desert in the night we heard a loud noise, like when the tires get debri and the motor of the vehicle lost power. We pulled over as we could and the truck didn’t want to start. I called the dealer for an advise with no answer back. As I could I towed the truck to the dealer on March 6 and finally March 26 spoke to technician and the motor had to be replaced. Is on back order and it will take 3-4 weeks. I’m concerned because the truck didn’t gave any warning just left us on the road. I was really scared because it was deserted area and no traffic. Really unsafe in that truck.

On [XXX] I was driving East on [XXX] in Joplin , MO at 75mph when my 2022 GMC Sierra put itself into Neutral. I could not get the truck back into gear and I was slowly decelerating. There were no warning lights or indications of a problem. When I was coasting down the Interstate and trying to get the truck back into gear, I would get a message that said "Conditions not safe for shift" I took the nearest exit and coasted to a stop in the end of the exit ramp. Once I came to a complete stop, my truck shut off. It never started again after that. I was blocking traffic from [XXX] and had to stand there for 30 minutes waiting on a tow truck to move me out of the way so traffic could flow again. There was no way to get the truck into Neutral again so that I could push it. The tow driver thought I had a bad battery but wasn't able to jump start it. I had him drop my truck off at my office where I planned to install a brand new battery. A couple hours later, we determined that the battery was not the problem. Still no warnings or indications of a problem with the truck. I towed it to the nearest GMC dealer the following Monday. It has been there now for 5 weeks waiting on a new 6.2L motor that according to the service department, needs to be replaced. I was told this is happening a lot across the US right now, which is the reason for no estimated completion time on my truck. I understand there is currently no recall or lawsuit even though, from what I was told, this potentially affects 880,000 vehicles. I feel that the way in which my truck stopped was dangerous and inconvenient to me and those around me. I would like to know what GM is doing to try and get these vehicles back running again and how we know that the replacement won't have the same issue a few more years down the road when the warranty is long expired. Currently in a loaner car from the dealer but as this is a registered commercial vehicle, we really prefer the truck back. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (

Was driving down the main highway in town when the truck suddenly shut off. No lights, no warning. Had the truck towed to the dealership and called my insurance company as I had recently had the fenders and hood repaired after having a fender bender in my front yard. The insurance company looked at the truck and inspected the motor and told me the motor had locked up. They said this was a common issue with the motor for my truck and they wrote a report about it. I emailed the CEO of GMC and requested help since my truck was just over the mileage that warranty would cover. Her assistant contacted me and agreed to check out the vehicle, investigate and determine a cause and see if they can supply assistance. After 6 months of investigating, they determined the crankshaft broke, but also told me the valves was a major contributor to that cause. They offered to discount the cost of a replacement motor. I declined, so they discounted it further. I declined again and they offered me one final offer of $7500 before tax for a motor and install. I had a quote from another local company for $6000 and told them no again. Her assistant said they could no further help me. I have the documents from my insurance when they investigated and I have the emails I sent but only 1 response from them. The rest of the communications was over the phone. It’s been a year and half and I still don’t have a running truck, but I have a 800 a month truck payment that I have to pay.

Steering control was maintained (though not power assisted) and brake control was in the same position. Truck was brought to a safe position in the breakdown lane and a re start was attempted to find that engine would not rotate and a number of dash indications were displayed including check engine. No indication of low oil pressure light nor any other warning was displayed prior engine shutdown event were noted. Truck was taken to an independent repair center for evaluation. Initial inspection noted that engine would neither turn via electric starter nor by manual rotation of crank shaft with a socket and breaker bar. Truck may be inspected near owners residence. Safety risk was low due to the low traffic condition of the interstate travelled at the time.

The transmission on this vehicle has given me problems. I have had the vehicle in a certified garage many times with complaints of a hard shifting transmission. First Chevrolet told me “it’s normal” but there is nothing normal about jerking so hard it throws a drink from a cup holder. Then I was told I needed a transmission wash. That was about $500 for it to “fix” the problem. Chevrolet told me the transmission was may or may not work and it may only be temporary. In my case it has reduced the hard shifting transmission but it’s still obvious. Now when I drive I remove my foot from the accelerator when it shifts from 1st to 2nd. I also make sure to keep a spill proof lid on my coffee because I never know when the transmission may throw it out of the cup holder.

During the first approximately 10 minutes of most drives, the vehicles speaker systems intermittently cuts in and out. This includes the turn signal audio and seatbelt chimes. It does not happen on every drive, I would estimate that about 2 out of 3 drives this issue occurs. All sound will cut out for about a half a second up to 2 seconds. After I begin the drive this issue will go away usually within 10 minutes however sometimes it is quicker than that. I have not taken the vehicle to be looked at due to others stating the dealer has no fix for the issue at this time. The turn signal and seatbelt chime cutting out can create confusion and may cause occupants to forget to buckle their seatbelt. No warning lights or messages have appeared in relation to this issue

Coolant control valve failure (P1098) after 50k service. When this engine code appears the vehicle goes into reduced power mode. While it does this at inopportune time and creates potential for colission with other vehicles such as when merging with traffic. The coolant control valve is a known issue and GM has just recently recalssified it from their powertrain warranty to their much shorter bumper to bumper or emissions warranty without notifity owners of this change. This move directly puts owners and drivers at risk while on the road. GM should be accountable to resolve this problem as failures are across multiples years and are happening to vehicles at all milages with some less than 5k miles.

The front chrome grill on my Sierra 1500 SLT has begun to detach, and there is currently a recall for this specific component on my vehicle. I took my truck to GMC Covert Bee Cave to get this recall and 1 other recall fixed, but GM does not have a remedy for grill. Not only does this pose a safety risk to myself, but I use my truck as a source of income by renting it out on Turo, and Turo has unlisted my truck from the app indefinitely or until this remedy is resolved. The paperwork I received from the dealership confirms GM has no remedy for the recall, and they sent me on my way without even offering a replacement vehicle. My truck is available for inspecting if you would like to see it. My safety and others safety is at risk if this recall does not receive a remedy or if GM does not give me a replacement vehicle in the meantime. No warning lights or any other systems can notify me if the grill is going to detach all the way, and I will not be able to have this source of income from Turo without the ability to have my truck relisted.

Engine blown traveling at 35mph vehicle is currently at Lake Chevy GMC in Lewistown Pennsylvania awaiting a new engine, dealer is warrantying engine (so far) awaiting new engine dealer said it will be several weeks before receiving the replacement engine. I’m aware there’s an ongoing investigation.. Thought I’d add my vehicle to the list of engines failures during normal operation.. Vehicle has 43,XXX miles completed its first tire change the day before.

ENGINE AND ENGINE COOLING

The contact owns a 2022 GMC Sierra 1500. The contact stated that while accelerating to 70 MPH to overtake a dump truck, the vehicle lost automotive power and stalled. During the failure, the message "Transmission in Neutral" was displayed and the vehicle coasted to the side of the road. The contact stated that the vehicle failed to restart and was towed to the local dealer to be diagnosed. The contact was informed that the engine was faulty and needed to be replaced along with the oil delivery system. The vehicle was not yet repaired. The contact was informed of NHTSA Action Number: PE25001; and indicated that the vehicle had experienced the failure listed in the investigation. The failure mileage was 20,016.

In August 2023, while driving on the interstate during rush hour, a critical engine component fell out of my vehicle, leaving me stranded in a dangerous situation. The car was towed to the dealership, where I was informed that a piston had fallen off the engine, requiring a full engine replacement. Now, in January 2025, my vehicle has once again failed—this time shutting off completely while I was driving on the Selmon Expressway, putting my safety at risk. After being towed to the dealership, I have now been informed that the engine has seized and will not turn, requiring yet another full engine replacement. This is completely unacceptable. As a loyal GMC owner, I have never experienced such catastrophic failures, let alone twice within such a short period. Engine replacements should not be a recurring issue, and I am deeply frustrated by the lack of reliability and the significant financial and safety concerns this has caused.

ELECTRICAL SYSTEM

Radio software glitch (bulletin 23-NA-183) cuts blower fan speed to 50% or below resulting in ineffective defrost during winter months. GM knows of the issue and has a radio software update but will not complete this as warranty and/or recall and will demand you pay for the correction. Due to the uncontrolled and loss of power to fan that cannot be corrected by the owner (ex. turning radio off/on will not fix it) this has become a serious safety concern as the windshield can fog, frost, or freeze while driving the vehicle.

At approximately 18,000 miles the engine on my brand new GMC seized up while I was taking 4 of my employees Downtown Detroit. The engine stopped as I was merging into 3 lanes of traffic from the left lane. I had to cross 3 lanes during rush hour almost resulting in a major accident. Then I had to wait 2 months to replace the engine. 25,000 miles later, the second engine seized up while I was transporting my father between nursing home facilities. The third engine, I have recently been told only has a 12,000 mile warranty. I have requested that GM give me a 60,000 mile warranty on this 3rd engine and they refuse as it is past 30 days since the 3rd engine was installed. I should be getting a new truck, but I am just asking for a warranty. This is a known problem, which obviously has not been fixed. In both instances, there were no indications of a problem until the engine stopped running. The first time, I had 4 of my employees, which I was responsible for, in my car merging in the left lane with no engine power during rush hour, putting everyone at great risk, including other cars and people. The 2nd time, I had my [XXX] father in transit between nursing home facilities. This obviously was a very stressful event for both of us. Both of the dealerships that replaced the engines confirmed that they have been seeing this same issue in many other GM trucks. I personally know of 3 people that this has happened to. In both cases, I had to wait weeks to replace the engine because of the backlog to order the engine for other people.

SERVICE BRAKES

The system that failed was the wire harness for the internal brake control. This is a well documented problem on YouTube and Reddit. I was driving home from the mountains, with my 7K lb camper, and I started receiving incessant messages alternating between "Trailer Brakes Disconnected" and "Trailer Brakes Connected". The messages made it impossible to see the speedometer and hear music or calls. Most importantly, I lost my trailer brakes in the mountains of North Carolina. Meaning the only way I could slow down was with my truck brakes, while a 7,000 lb camper was pushing me. I took my truck to the dealership today and paid $166 for a diagnostic. The stated the issue was with my camper. I tried to explain that many owners were having this problem and it is well documented. They stated there was no recall on my vehicle and gave me a print out of what to check on my camper. I checked my camper and there are no issues and no issues when i connect it to my other vehicle.

Engine Mileage is 72,728, on my 2022 GMC Sierra 1500 AT4, L87 V8 Engine. While driving [XXX] to drop off a co-worker at a Toyota dealership, my engine started making a strange "clicking" sound. A Toyota tech came out to look at it quick and suggested I try to get to a GMC dealer about .5 miles down the road. I made it about 100 yards before the entire truck shut down. The dash went black and then engine stopped running. Had to get towed to the dealership. Engine is considered "dead" by Diamond Auto in Worcester, MA, and the cost to replace the L87 V8 Engine is quoted at roughly $11,717.89. There have been zero prior engine issues on this vehicle. The engine failure came out of no where. Thank you for your time- [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have a 2022 GMC Sierra 1500 AT4 with a 6.2 engine. The truck had roughly 50,000 miles on it when the engine completely stopped working while I was driving on a busy multi lane highway during rush hour. After almost getting hit by multiple vehicles while trying to glide my truck to the side of the highway. I waited 2 hours trying to get my truck towed to a local dealership and the next day was told that my engine completely seized up and my engine needed to be replaced. I waited two months without my truck while it was at the dealership waiting on an engine that was back ordered. They told me it was complete engine failure. They couldn’t figure out why, all fluids were good yet the engine failed.

I currently own a 2022 GMC Sierra with 75823 miles on the vehicle. I purchased the vehicle new from Bill Cramer GMC, and just learned today that the engine has to be rebuilt due to bad lifters, cam shaft damage, and excessive oil consumption. According to the dealership and further research, this is a common issue with the GM 5.3L engine that is currently in my truck. Because the truck is now out of warranty GM will not cover the costly repair. Something has to be done regarding these engines, due to the thousands of people this has affected. According to the sites, no recall has been issued for these engines and its very dangerous to operate because the engine can lock up while driving.

On or around January 27 2025 my 2022 sierra loss power and shut down at night and dropped to 0 rpm. I was close to the house and got pulled home by relative. When I did get it cranked lifters were tapping which was common in the 6.2 but I drained my oil and filter and saw the glitter look. Truck was still tapping after warmed up. Last night I about got hit at an intersection when same thing happened. I felt a jar, and truck went to zero rpm and loss power. Truck said, put in neutral and try again. When I pushed starter had a click. Then I pushed start again and it started smoking. It burnt my starter up, because engine is seized. I saw where there is an investigation on this and I really hope it goes through because that was a scary moment and it is safety concern. Twice the same thing. But now can’t turn crankshaft, nothing to drive, making payments on a 80,000 truck that is my personal and work vehicle. 92000 miles on my truck and have my oil changed regularly. I’m stuck between rock and hard place, but will be getting it towed to a dealer somewhere. To here I need a 6.2l engine in my sierra slt. 2 year old truck it is stressful. I know im going to here 10,000 $$$ I don’t have.

They couldn’t or didn't put an inspection sticker on the truck because I honestly don’t think it could have passed inspection. The truck sounds like a truck on Transformer when I turn it off breaking town like a robot. On yesterday which was 1/27/2025 while backing up to turn around the truck started dragging in the back like the breaks locking up, the same thing happened while turning into my driveway off a state highway with an 18 wheeler coming. GMC can’t look at the truck until February 10! This Truck was purchased new and it’s been nothing but trouble. Electrical system goes in and out Steering assist reduced drive with care, Engine power reduced, park assist on then off and truck making unusual noise. I waited 13 YEARS to finally get another brand new vehicle and this what I ended up with. My last new vehicle was a 2004 Honda Pilot. I had 459,000 miles on the truck no engine or transmission issues. I donated the truck to Goodwill.

Engine locked up while driving down interstate. Found out it’s the 2nd engine that has been replaced. On its 3rd engine now. GM 6.2L

Day1: vehicle stalled resulting in warning lights related to the batter. Day2: battery was replaced. Day 3: vehicle was driven less than 30 miles and starting making noise under the hood. vehicle stalled in road and was towed to repair shop/dealership. I then received notice the stater needed to be replace to start the vehicle to diagnose. The vehicle started and it was determined the engine was blown and needed to be replaced.

Started using oil and dealer said GMC says it can use 2 qts in between oil changes and few months later driving on interstate and quit running got it home and clinging and wouldn’t start got it to dealer said the engine seized up bearing spun. Took 2 months to get truck back and now afraid it will happen again. GMC should offer a buy back or different year of truck at no cost.

I was on a hunting trip when my almost brand-new GMC Sierra 6.2L broke down, approximately 20,000 miles on it. The vehicle started making a ticking noise while I was driving out of state, en route to our lodge. Early the next morning the engine light came out and the vehicle came to rest close to a stop sign. I was very fortunate someone was following me in a different vehicle. The vehicle would not start afterward and had to be towed to the closest dealership. Being a new GMC owner and nearly 7 hours away from home and in an unknown area was extremely stressful. The dealership service department was closed on Saturday (the date of the incident) and Sunday. The dealership was less than helpful and did not return my phone calls on an already stressful day. My trip ended on Sunday and I was forced to rent a car at Enterprise. Unfortunately, the Enterprise I contacted did not have a truck and GMC told me that the dealership could not provide a loaner truck. I’ve needed a truck several times this month, which has caused difficulties for me and others. The vehicle has since been inspected and the service department stated the vehicle needed a new engine. This occurred 21 days ago and there is no end in sight. The service department could not tell me an exact date on when the engine would be shipped to their store.

Engine seized up. This is the second 6.2L engine that this happened to. The first one was a lifter failure and 2000 miles After replacement engine locked up. Brand new engine at 26000 miles. Now at 68000 the new engine seized up with no warning

ENGINE

While traveling on the highway the engine shut off. No warning, noises or lights where on before. Check engine light came on when the engine shut off. Was able to get off the road on to the shoulder. This was an huge safety concern as I had no way to move the truck. After getting the vehicle to the dealer it was a spun rod bearing. Had 7000 miles on it at the time. Dealer replaced the the parts and had the truck back after three weeks. Metal is oil pan. 1, 2 and 8 rod bearing spun scoring on main bearing and crankshaft. There was no issues with the truck prior. I bought it new.

ENGINE

I am on my third 6.2L engine at 80k miles due to engine failure. It is absolutely ridiculous and is a safety issue for sure. It has left me stranded twice. And now GM is giving me a hard time about not wanting to cover it under warranty.

ENGINE

While driving, I was starting to move following being stopped at a stop light and the truck experienced a complete engine seizure. I had it towed to the dealership I purchased the vehicle at and after a day or two, they indicated that GM's recommended fix to this particular issue was a complete engine replacement. The engine replacement couldn't be scheduled in a reasonable time. Grant it that the repair would have been covered under warranty and they would provide me a rental until such time it could be fixed, I decided to trade the vehicle in on an equivalent 2024 model (same truck 2 years newer) after being assured that it was an isolated incident and not part of a systemic problem. I only am writing this since I read an article the other day indicating that the NHTSA was launching a potential investigation into the same issue based on 39 complaints, at that time, regarding the GMC's 6.2L V8 small block engine. I wanted to let your organization know of my issue as well since I would assume that there are far more than 39 people/owners that had experience this problem. At a minimum, I make 40. In addition, I am now concerned about my 2024 GMC since it has the same motor in it. The article mentioned that there has not been injuries associated with the engine seizure. This is not surprising to me. It actually happened twice in my 2022; the first time in my driveway and another on the road. Note, after sitting for a couple of days in my driveway, it had started right up. I went for a ride to test it out and that is when the final instance happened. Both instances occurred when the auto off feature was engaged and only seized when trying to move from the auto "off" position back onto the "on" (engine running) position so I was not moving in either instance. Again, I am not concerned that this issue will arise in my new vehicle.

Engine suddenly started knocking and loss of power while driving on the highway. If engine had stopped or locked up it could have caused an accident. Took it straight to my dealer on Dec. 30, they said to leave it that the knocking was coming from lower part of engine. Couple weeks later they called and told me it was crank bearings. Very disappointed I only have 11000 miles on it.There was no prior warning lamps or symptoms. They have a new engine on order but said there is a nation wide back order, so no way to know how long it will take to find one.

Used my truck to back out of the driveway and wouldn't go into reverse at all. Towed to dealership and said problem was transmission valve body went bad. Dealership said TVB fail all the time in these trucks. They told me that this part is on back order and could be 2 or 3 months to get part in. GM has and known transmission issues . This truck is little over 2 years old and only has 40k on it. I'm hearing that TVB are failing while driving and creating dangerous situations and GM isn't doing anything about . Truck is under PT warranty. I asked what can't GM just put a new transmission in? They say it's not cost effective. So cost is over safety i said!

6.2L Engine burning excessive oil, so dealer per GM started an Oil Consumption test at 34,457 miles went through the process until 45,145 miles and dealer took it in at 45,468 to tear down engine, I contacted GM Aftersales and Customer Service VP and he had a representative start working the case, Engine was found to have scored cylinders on the driver's bank decision was made to replace engine. Engine was replaced and picked up vehicle and was told to bring it back in 5k miles for an oil change. I brought it back in 1k miles and retained the filter and used a filter cutter and inspected the filter. Filter had a significant amount of Metal and Metillac pieces imbedded in the filter (I have the filter still) I reported this to the Dealer and GM Aftersales and Customer Service, They noted this a normal! I then had the filter only changed at 500 more miles and still contained some debris, this is the second truck that I have owned the first was a 21 same issue first replacement failed in 25 miles, 2nd motor failed at start up and then I traded into this 22' and took a major financial hit on trade in, then a 3rd motor in the 21' and it made it so the truck could be wholesaled or sold, by this time I had bought this truck that has just had the motor replaced and currently have 7k on the new motor which was replaced under warranty. I feel confident that the metal debris that was in this engine is a contributing factor if not the factor that is causing the engine failures and suspect this engine will have the same demise. I welcome you to take possession of the filter and inspect it yourself. I have a video of the filter that I would be glad to share. These engine failures have cost me $25,000 in trade in loss.

Driving at highway speeds 60 mph. The upper grille (as GMC calls it) came off of the truck, hit my windshield and the car behind me also hit it. This is a known GM problem and they are not issuing a recall on this. We are lucky the car behind me didn't suffer any damage nor swerve to miss the flying piece of my vehicle. This is a huge safety concern that needs to be addressed. A quick google search will reveal many other people having this same issue. Some stating damage to their vehicle as a result.

My engine locked up on me 3 times without notice or warning at all while driving 75-80mph down the highway. All the times myself and my family were put in danger of being hit by traffic and the locations were the vehicle stopped was around a curve where other drivers wouldn’t notice until it was too late. Freezing cold and could stay in the vehicle scared we might get hit while inside. Second time it stopped at around 10:30om in the middle of nowhere in [XXX]. Even the cops couldn’t get us tow. Finally 6 hours later a friend had to come get us. I reached out to the GM CEO per email and no reply. I tried to get them to take the vehicle back and after supposedly fixing the engine after having it for 3 months I got it back with no loaner to use during this time. The engine failed again a month later. Again after supposedly fixing the engine it failed a third time. If failed the first time in January 2024 and the second time in May 2024 and then the third time in July 2024. I have anxiety and now taking medication from even driving this vehicle afraid it will stop again. Replacing the engine isn’t acceptable to me. Please help. The first place to to rebuild the engine Crossville, TN (Dave Kirk Chevrolet GMC), then it to Parks Buick GMC-Greenville: 2640 Laurens Rd, Greenville, SC 29607. and then to Loves Buick GMC, 736 Saturn Pkwy, Columbia, SC 29212. I have all the email sent to GM leaders and their executive leadership team. My vehicle had only 22,000 miles on it and I guess doesn’t fall under the lemon law in SC so they didn’t want to take it back. I feel helpless in this situation. Even getting a lawyer isn’t guaranteed a win and then I’ll be out of more money. Being a [XXX] this really sucks to be treated like my life and family life doesn’t matter. I bought the vehicle brand new from Jim Buick, GMC, Cadillac in Columbia, SC. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

STRUCTURE:BODY

I was driving home from work on the highway, when the top part of the front grill broke off and flew up hitting the windshield. It caused me to abruptly swerve into the other lane of the highway. Luckily there was nobody in the other lane. The part could of also hit another car that was behind me. Going on line, I see this is quite common issue for 2022 GMC trucks and it occurs on the same conditions, driving down the highway. I suggest a recall to get this fixed.

UNKNOWN OR OTHER

The tailgate will drop completely down by itself while driving at highway speeds. It has happened numerous times while driving on the interstate highway when I had large items in the back of the truck. Items such as propane cylinder, large cooler with ice and drinks, luggage, furniture, etc. The first time was a few days after buying the truck in Sep 2022. I reported it to the dealer, the ordered a replacement electrical component and replaced it. That did not correct the problem. I took it to another dealer in early 2024 and they worked on it but said it was going to be a recall by GMC but they did not know when. It's been almost a year and the tailgate still falls down by itself completely at random. It just happened again today while driving in heavy traffic on city streets. Fortunately, I didn't have anything in the back of the truck. It happened once during the night while the truck was in my garage and hit the garage door. I no longer put anything in the back of the truck, but I am concerned that it happens to others or will happen and someone on the highway will be seriously injured when a large heavy item falls out on the interstate highway. It can cause a major accident and GMC is obviously not as concerned as they should be. It's not the dealer's fault and is solely GMC's responsibility to correct this condition before someone is injured or killed.

While driving on the interstate at 75 mph, the top trim from my grill flew off unprovoked hitting my windshield and roof of the truck. Luckily there wasn't anyone behind us but the noise definitely spooked myself and the passenger not knowing what just hit the windshield. I took it into the dealer from who I purchased the truck and told the entire grill must be replaced for a whopping $1571.26 not covered under warranty. The truck only has 24000 miles on it and cost near $80K. Thanks GMC!! Scorned customer.

STRUCTURE:BODY

Entering a freeway and getting up to speed, the moulding between my grille and hood flew off. I was not able to recover it, therefore it has not been inspected by anyone. Luckily, this happened at night when there were very few drivers on the road, but had it happened during a busy time, it is likely that piece would have hit another vehicle(s). It has been reported as a problem on many forums. This happened without warning and there were no warnings after it occurred.

POWER TRAIN

My 2022 Sierra Denali shows message "Shift To Park" when turning off, even though it has been shifted to park, the dashboard stays lit as well as the radio on. Horn even goes off alerting as if the engine is on and me walking away with the key in my pocket even though engine is off. Have to play with shifter to get it to stop, sometimes turning it back on and off will do trick. Locking it with remote works most of the time but when this happens, I can't use remoteless key access, door just won't lock.

UNKNOWN OR OTHER

Tailgate opens up in Park and/or when Truck is shut off. Tailgate continues to click after it opens itself. I have found my truck battery dead if left connected overnight. For the last week i disconnect the battery when i shut the truck off, and reconnect when i want to start it to insure getting to work on time. Same problem as what is described on the current Recall N242469160. But yet my truck is not show a recall on it.
