1. What component or system failed or malfunctioned, and is it available for inspection upon request? The issue was with the gear select switch and jumper harness, related to the "Shift to Park" malfunction in my 2019 GMC Acadia. Yes, the components were available at the time of the repair with the GMC dealer. 2. How was your safety or the safety of others put at risk? The vehicle would not recognize when it was in "Park," which prevented it from being turned off. This could lead to unexpected vehicle movement or battery drain, and creates a safety risk if the driver assumes the vehicle is secure when it is not. It also poses a hazard if the vehicle cannot be safely shut down in an emergency or in unsafe conditions. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the issue was reproduced and confirmed by a GMC dealer during an appointment on July 22, 2025. They diagnosed the problem and verified that the gear select switch and jumper harness needed replacement. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle was inspected and repaired by an authorized GMC dealer. 5. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No, a "Shift to Park" warning message appeared and the vehicle would not allow me to turn it off without shifting in and out of park multiple times. This first occurred on July 18, 2025, and continued until the repair was made.

On my 2019 Acadia, the message shift to park keeps appearing on my dash when I shirt the car into parked. It's getting more frequent and when I called GMC it's a well known problem to where the lady taking my appointment says yes we are aware it's happening alot. They want to charge 800 to fix a problem that should be a recall. It's a well known problem and there has been cases and suits brought up and GMC will not make a recall on this even though the mechanic said I can't believe this hasn't been recalled. Can you help with making GMC do a recall in the Shift to Park. Thank You

When I park and then turn the car off the car fails to recognize that the gear shifter is in the park position. As a result, the car doesn’t fully shut down, leaving the engine running or the electronics active. This drains the battery. I have seen this issue is recalled for other 2019 Acadias but don’t under why it is not recalled in mine. I’m afraid I’ll be out and about and unable to turn my car off resulting in a dead battery and being stranded.

July 31, 2025 Our 2019 Gmc Acadia would not shut off in a parking lot, I was 45 minutes from home. A message on display says shift to park. This is a safety concern as the vehicle might not be fully secured in park, the vehicle won't shut off and will drain your battery. There is an ongoing class action lawsuit related to this issue, alleging that GM has been aware of the problem for some time but has not provided a satisfactory fix according to Lemon Law Auto Fraud. I called the gm dealer and they quoted me $500 to fix this issue.

Last week, the coolant gauge , on our 2019 GMC Acadia, was reading below "C".... The "Steering Assist" warning was disabled on the on-screen display and the Air conditioning stopped working. Took the car to a mechanic, who read the codes.... Mechanic stated that all symptoms were based on a defective GM thermostat. The thermostat was "stuck-open" causing the "steering assist" to be disabled as well as the A/C from being disabled as well. It seems GM has updated the part since when the series of Acadia were manufactured. After getting it repaired, at of our pockets, we researched and noticed that thousands of other GM Acadia owners had the same exact 3 symptoms: (1) malfunctioning coolant reading (2) "Steering assist" disabled (3) a defective ("stuck-open") thermostat..... Symptoms were exactly the same for all parties involved. We have owned many vehicles never had a thermostat fail before 65k Miles.... It became a safety issue since the car disables the "steering assist" based on the thermostat being stuck open. Contacted GM corporate which stated unless a recall, there would be no compensation. GM needs to make it right for the thousands of GM owners whose car has the 3.6L engine In short, this is a major issue since the car's steering system is NOT working correctly We would like a recall to be initiated. Thank you.

Vehicle's "SHIFT TO PARK" warning is often displayed when vehicle shifter is in PARK and then the engine is turned off. Often takes several attempts to correct the problem by restarting and turning off the engine or by manipulating the shift lever while in PARK. These is a current recall for this issue with the same year, make, and model of vehicle. Checking the VIN against the NTSB recall list shows this vehicle is not included in the recall.

Shift to Park Vehicle does not recognize the gear shifter is in the park position. Vehicle does not fully shut down.

POWER TRAIN

When trying to park car, vehicle will not detect the shifter is in park. If the car does not detect its in park it will not turn off and stays running hampering your exit from the vehicle. This is truly an unsafe condition due to not knowing how to get the car to shut down as well as not knowing if the car will roll if you do get out.

UNKNOWN OR OTHER

Shift to park error message consistently displayed forcing repeated restarting of the vehicle so that it finally recognized that the vehicle was in park and would unlock the doors for safe exit from the vehicle. This was a known issue by General Motors and they have 2 class action lawsuits filed n the states of Ohio and Tennessee for this issue with well over 110,000 vehicles affected. General Motors refuses to acknowledge this defect and fails to issue a recall. Their only offer when I took this vehicle to a GM certified dealership was to offer 15% towards the replacement of the shifter assembly. The excuses made were the vehicle was out of warranty as well as over in mileage. I bought this vehicle used from an Acura dealership and accepted delivery of it on [XXX] with approximately 33,417 miles. I started to experience the shift to park error message at 36,013 miles in early May 2025. By the time I was able to receive instructions from GMC customer care and secure repair for this issue the vehicle mileage was approximately 37,000 miles. It is not a pleasant feeling to be trapped inside your vehicle until you can get it to finally recognize that the vehicle truly is in the park mode. With the hundreds of thousands of vehicles on the road with this issue I feel GM should recognize their problem and perform a vehicle recall. This flaw had been installed in numerous GM vehicles manufactured as early as 2017. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

We receive a shift to park message when we try to turn our 2019 GMC Acadia off. The vehicle is already in park, but an alarm bell keeps going off telling us it is not. The vehicle will not allow us to shut off the vehicle properly and results in battery drain and inability to lock the vehicle. We have noticed there is a class action lawsuit and recalls from previous year's models and the 2019 model manufactured in Ohio, but ours was manufactured in Tennessee. Our year, make, and model isn't listed in the class action lawsuit and/or a recall. This is very frustrating considering the number of similar issues/complaints in regards to this shift to park problem. I feel GMC as the manufacturer should be held liable for a faulty part and they have failed to correct this issue in later models since they were aware of the issue with the 2017-2018 Acadia models built in Tennessee.

In March 2025 my 2019 Arcadia with only 44112 miles begin indicating a Shift to Park error message when I parked and shifted into park the error message showed on the instrument panel and the warning alarm sounded and would not stop showing the error message until I restarted the car and shifted from drive to park repeatedly. I couldn’t get out and close the door, and the warning stop, it would continue to sound the warning. The only way to stop the warning message and alarm was to stay in the car and repeatedly start the car shift to drive into park switch it off and if it still showed the error and warning, do it all over again. This could take up to several minutes and many tries. If I had of left the car all the warning would have been sounding indicating it wasn't in park. I didn't know if it was really in park or not and if not, the car could have potentially rolled off causing injury or damage. To try and determine what was the cause of this problem I searched the internet to find a solution, to do a reset or simple fix and discovered that GMC had known about this issue since 2016 and the only solution was an in the shop repair requiring replacement of some parts. The "Shift to Park" error in GMC vehicles is considered a safety issue by many owners and has led to class-action lawsuits. The issue, which prevents vehicles from recognizing when they are in park, can lead to the engine not shutting off, potential for vehicle roll away, and even entrapment inside the vehicle. On April 16, 2025 I had the repair done at Hayward Allen, Cadillac – GMC dealership, 2590 Atlanta Highway, Athens Georgia 30604. The total repair cost was $732.36 (invoice attached). ). I sent a copy of this invoice by email to GMC customer service. After customer service reviewed the amount they call and informed me they could only reimburse me a total of $73.24.

SUSPENSION

I took my 2019 GMC Acadia in for an inspection and was informed that the toe links were loose and fail inspection. Upon researching this failure, I found that there is a recall for this, but my VIN was no included. I don't understand why not given what I'm seeing from other owners. I quote from the GMC Authority site: [XXX] "GM and the National Highway Traffic Safety Administration have issued a recall for certain 2022 model-year Cadillac XT5, Cadillac XT6 and GMC Acadia crossovers over an issue related to the rear toe links. The problem: affected vehicles may have a left-rear suspension toe link with a fastener that was not properly tightened during assembly at the factory. The GMC Acadia is built at the GM Spring Hill plant in Tennessee, but will soon be moved to the GM Lansing Grand River plant to make room for the Cadillac Lyriq. The Cadillac XT5 and XT6 are also built at Spring Hill and will remain there for the foreseeable future." Based on other feedback seen, it appears this should be a recall for my vehicle as well.

My 2019 GMC Acadia is now undergoing the same repair for at least the second time. This is the common issue known as the Shift-To-Park issue. You can read about it here - [XXX] Below are the commonly affected years: 2017 – Acadia 2018 – Acadia 2019 – several models (I own a 2019 GMC Acadia) 2020 – several models 2021 – Acadia and Traverse Despite falling into the year, make, model and issue - When I look up my VIN - No recall or warranty information is available, saying that my vehicle is NOT affected by this issue. However, this is now the 2nd (maybe 3rd) time I am having to come out of pocket to have this issue repaired. It originally happened in July of 2022 with around 40-44k miles on the vehicle. It is now happening again May of 2025 with around 72k miles on the vehicle. If I search further back, I imagine the first owner may have had the same work done too. Clearly this vehicle is affected by the issue buy according to my VIN it is not. GM (General Motors) told me that they offer no sort of help or reimbursement unless my VIN is associated with the issue. Can you guys please either add my VIN or extend out the warranty / recalls to ALL - Because this is absurd. My car doesn't recognize that it is in Park and stays on, preventing me from shutting down the vehicle / engine.

While driving the thermostat will go to zero and the steering assist is disabled. I have read a lot of forums that this is a known issue. The only way to reset it, so we have A/C is to disconnect the battery and it will last a day or two and do the same thing.

“Park to shift “ warning keeps showing up when shift the gear to PARK.

UNKNOWN OR OTHER

My 2019 GMC Acadia with 33,000 miles on it started to give me a notification to "Shift to Park" even though I had already shifted the vehicle into park. A "ding! ding! ding!" alarm wouldn't go off and the vehicle wouldn't turn off unless I repeatedly changed the gears until it read it was in park. This went on for a few weeks and got progressively worse. I read on a GMC forum that the vehicle could slip out of gear while driving and potentially cause an accident. My mechanic found the shifter assembly to be defective and replaced the entire Gearshift Lever Assembly. He said there was a plastic piece in the gearshift that snapped off and said this was an issue in the older models but thought GMC had fixed this issue by 2019. Unfortunately, I was past my 3 year / 36K mile warranty and had to fork over $1300 to have it repaired.

Our Arcadia 2019 with 40000 miles has shift to park problem. 2017 thru some 2019 had recall notice and were fixed by GMC. Why doesn't it apply to this vehicle. We had to pay $1500 to dealer. There is an obvious problem and they have admitted it. Time for government to step in or do a class action lawsuit looks like they are filed by state

The contact owns a 2019 GMC Acadia. The contact stated that occasionally while attempting to park the vehicle and shifting the gear selector into park(P), the message "Please Shift to Park" was displayed; however, there was no warning light illuminated. The contact was unable to turn off the vehicle during the failure. The local dealer was contacted; however, the vehicle was not diagnosed. The contact was informed that the VIN was not under recall. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 77,000.

UNKNOWN OR OTHER

I am receiving a "Shift to Park" notification on most instances that I shift the car into park. When this warning engages, the car will not allow me to turn it off as it does not recognize that it is in park. After researching this issue, I found that there is a GM Recall for 2017-2019 GMC Acadias for this very issue. However, my VIN is not included in the recall so I do not qualify to have the issue fixed and would have to pay a substantial amount out of pocket.

ELECTRICAL SYSTEM

When I park my car it beeps and says my car is not in park. Many other models of the 2019 GMC Acadia, along with other GM vehicles, may be affected by a "shift to park" recall. This recall addresses a defect where the vehicle may display a "shift to park" warning message even when the vehicle is actually in park, potentially preventing the ignition from being turned off and the key from being removed. This is exactly what my car is doing but they say my VIN is not included in the free fix. I brought my vehicle after it died to a GMC dealership and they said it will cost 1,000 to fix. My safety is at risk because I drive to different locations as a therapist and I often drive home at night in remote locations.

Some times when vehicle is shifted into park it doesn’t recognize it is in park. I have to turn the vehicle off and restart it, shift into drive and back into park. Sometimes it takes a few times. My neighbor has a 2018 Traverse and had the same issue.

I have had intermittent issue with a message to shift the car to park when I shut it off. It was in park. If I wiggled the shifter it would often correct. That went on for a few years on and off. Lately it was more persistent. I brought it into the dealer and they replaced a harness and a switch. Seems that a harness would not go bad unless it had a manufacturer defect. I have seen a lot of reports on this issue on online blog sites. Seems to be a common problem. The problem with this defect is that when it is sin that mode, you cannot safely secure the vehicle and warning bells keep ringing. So the vehicle cannot be left like that and expect it to be secure.

When shifting into Park the car still states to "shift into park" on the dash and will not fully shut off. i still need to take the car into the dealer for service to fix. This seems to be an issue.

I have a 2019 GMCAcadia Denali with less than 60000 miles. The problem I have with the vehicle is I get a error that say "Park to Shift. I don' know if it is in park or not. I am afraid that it isn't in park and will create a safety issue and injuries. It is my understanding that the same problem with the 2020+ GMC Acadia and is listed in a RECALL. Why isn't 2019 not included in this recall?

When you go to park the car and put it in park the car says shift to park with it already being in park. It is concerning that the vehicle is not recognizing it being in park

Im a travel nurse and I was working in Vermont. As I was driving on the highway in New York on my way back home a shift to park light came on, a stabilitrak light came on, power steering light came on, ABS light came on, and my check engine light also came on. My vehicle started slowing down as I was driving and my lights on my dashboard were turning on and off and my speedometer was not working. I was able to pull to the side off the highway so I could get out of harms way. I made a call to OnStar for help and they asked to if I made it to a safe location. As the car was still on I was able to take the next exit and ended up in an auto zone parking lot. As I made it in the parking lot I turned the vehicle off but only the engine turned off but everything else stayed on and the shift to park light kept coming on when the vehicle was in park. I was in the parking lot for 3-4 hours freezing in my vehicle until onstar came to tow my vehicle. By the time onstar came my battery in my car had drained and it was a new battery. I was told that I would have to contact auto transport to transport my vehicle to Louisiana at the dealership where the vehicle was purchased. I paid $1600 to transport my vehicle back home and I had to find a way to make it back to Louisiana. I didn’t have a credit card so a friend of mine was able to rent me a vehicle to get home and I paid a total of $1700 on a rental because the dealership in Louisiana couldn’t give me a time or date the vehicle would have been finished. I have been to the dealership 3 times now for the same problem in less than a week. I have paid $1500 altogether to fix damages on my car that I noticed other vehicles with the same make and model had the same issues. I never had a problem with my vehicle before everything just started happening all at once. I’m currently having to pay for car rentals to get to and from work and to make sure my kids get back and forth to school. My vehicle in at the dealership again for the 3rd t

Driver side blind spot not longer works. When driving the blind spot indicator just stopped working a month ago and I didn't take notice until I almost hit another car. I contacted gmc about this issue as well and was also told there isn't any recall for this and it would have to be diagnosed by there mechanics. There were no other issues prior to this. Also the "shift to park" warning has been popping up for 3 days now when my car is in park. My car won't complete shut everything off until that warning is turned off. I called GMC of puyallup and was told only certain vin qualifies for the recall for the gmc 2019 acadia. That's absolutely ridiculous! I can't exit my vehicle until the car senor knows my vehicle is in park which is a major concern and safety issue because my home is on a slope.

Yes, my vehicle is available for inspection upon request. When I go to put my 2019 GMC Acadia in "park" the shifter states it is in park & the dashboard shows it in "P." However, when I turn the vehicle off, an error message comes up reading "shift to park" and my car wont fully shut off. You can feel the car move forward or backwards a tiny bit (depending where vehicle is parked). This makes me have to turn the vehicle back on, shift into "drive," back into "park," and then shut the engine off and pray the "shift to park" display doesn't come up. This process was repeated this morning when I arrived at Walmart 3x before it finally shut off, then when I got home it happened at least 8x before I could safely leave my car in my garage without the worry of it not truly being in park. This has gotten to the point I have bought wheel chalks to put around my car tires because I am afraid this vehicle could roll down my driveway into my neighbor's house or kill some kid playing in our culdesac. I let the last place I was at know & they told me GMC was aware of the issue, but that there was no way to fix it (Auto Revival in Justin, TX). I am unsure as to whether this issue happened for them or not, as nothing was mentioned after being told GMC is aware. That was on January 10th, 2024. No one else has looked at it besides that. It seemed to be occurring less frequently for several months, and then now it is the worst it has ever been.
