POWER TRAIN

The vehicle only has ~39,000 miles on it and the transmission went out and the car is not drivable. The dealership said it is a faulty valve body and that the part is on national back order and could take 2 to 6 months or even longer to get the part before they can start work.

ENGINE

The engine light comes on and then the rpm's drop to 35 and a notification comes up that says "reduced acceleration. driving with caution". If I stop and turn of the vehicle and restart the rpm's will be better but the truck still seems to have a difficult time increasing in rpm's and accelerating gears. It's incredibly dangerous as if I'm driving at a substantial speed on the highway or freeway and it drops rmp's rapidly I'm likely to be in an accident which could be detrimental. The dealer has had my vehicle on two separate occassions. The most recent time they've had it for 5 days and still do not know what's wrong with it. The engine light will not turn off.

STRUCTURE:BODY

Since purchasing the vehicle on September 27, 2024, I have experienced a series of troubling issues that raise serious concerns about its design, manufacturing, and overall safety, including: Airbag system malfunction: My airbags were nonfunctional for over a month. Tire-related issues: Required full replacement of the initial set of tires. Persistent alignment problems Bluetooth audio problems: Poor quality and connectivity with multiple phones, resolved only after a service visit in May 2025. Defective seat frame: Rear passenger-side bucket seat required full replacement. Defective paint: Blisters and bubbles in the rear quarter panel paint. Fuel module failure: Most concerning, the vehicle abruptly stopped on the road last week and required towing. I was later told the cause was a fuel module failure. Each of these issues is concerning on its own. Taken together, they represent a troubling pattern of unreliability and potential risk to my safety and that of others on the road. They’ve also resulted in a significant loss of my time. This vehicle has spent over a month at the dealership for service—astounding for a truck that’s only eight months old. These are the kinds of delays and disruptions I specifically try to avoid by purchasing and maintaining new Chevrolet vehicles.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

I have had my cruise control set and my car will slam on the brakes with no vehicles in front of my car or on each side. This has happened multiple times, it doesn’t matter if I am going 40MPH or 60+MPH. I have taken it in and they say there is nothing they can do for the issue. I’m worried for the safety of myself, my family, and my unborn child. As well as any cars around (behind me potentially) when this happens. I do not want to unintentionally cause an accident.

ENGINE

I parked at my home, approximately 5 minutes after arriving home my grandson ran in yelling papa your car is on fire. The engine was on fire, shooting flames onto the windsheild. The cause of fire is unknown at this time.

ENGINE

I was entering the interstate, at 65 miles per hour, and went to set the cruise once I reached 70mph, and noticed that I was losing power, the engine had stopped and we dangerously lost speed on a interstate where folks were traveling north of 75-80 mph. I costed to the shoulder and tried to reset with no luck. We called Onstar and had it towed to Hendrick or Monroe NC. We found out that this was an engine failure and the long block had to be replaced. This left us stranded without a car to drive to our cruise —GM told me I could buy plane tickets and they’ve never denied reimbursement. Unfortunately they denied it once I submitted all the receipts. It been a horrible experience with no help from GM.

ENGINE

We were driving down the [XXX] in Wichita KS when our 2024 Suburbans engine shut off and the car went into neutral. The display said “ "conditions not correct for shift". We were able to safely coast to the nearest exit [XXX] and we completely stopped at the bottom of the exit ramp. We contacted onstar who dispatched Kansas Highway Patrol who blocked off the exit until we could get the vehicle towed. The car is currently at the dealership, being that it is Sunday they are closed so more information tomorrow on the issue. The photos are of the car being towed from The incident location and dropped off at the dealership. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

EXTERIOR LIGHTING

The contact owns a 2024 Chevrolet Suburban. The contact stated that upon brushing snow off the vehicle, the contact noticed that there was snow inside the headlights, which later turned into ice and dimmed the headlights. The contact stated that while driving at an undisclosed speed, the failure recurred, causing the contact to pull over to the side of the road to clean the headlights. The dealer was not notified of the failure. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 360.

BACK OVER PREVENTION: WARNINGS

The check engine light came on at 14k miles indicating there was an emissions error. The brakes squeal and have had to be replaced 3 times since the original purchase in March of 2024. After the third replacement of brakes they still squeal. Even if the car is not braking it makes the noise. The radio shuts on and off constantly. Chevy reported they are aware of the issue but there is no fix at this time. The dealerships reset the radio but the issue persists. I’ve had to park the car because I’m afraid the brake issue is much more than they’re willing to admit.

POWER TRAIN

On[XXX], at approximately [XXX], while driving on [XXX] at a speed of 80 mph, my vehicle suddenly lost all power and shut down without warning. I had no choice but to steer to the shoulder lane amidst high-speed traffic on the busy interstate. After coming to a stop, the car would not restart, leaving me stranded in a highly precarious situation. As the weather conditions worsened, turning into a blizzard, and darkness set in, I contacted GM Roadside Assistance for help. I was informed that assistance would take at least an hour to arrive. Feeling unsafe, I called local law enforcement. The officers arrived and parked behind my vehicle with their flashers on to ensure approaching drivers would slow down and avoid an accident. This was an extremely distressing and frightening experience. After an hour, GM Roadside Assistance called back and informed me they were unable to find an operator to tow the vehicle. By this time, the officers on-site had contacted a local tow company for my safety. The tow company advised me that I would need to pay in cash for their services, which I accepted due to the urgency of the situation. They towed the vehicle from [XXX] to their yard in Douglas, Wyoming. I then arranged for a ride to Cheyenne, Wyoming, where I had to report to work that night. This incident not only jeopardized my safety but also left me with significant unexpected expenses and inconvenience, all due to what I believe is a manufacturing defect in the vehicle. A new vehicle should not experience such catastrophic failure, and the delayed response from GM Roadside Assistance compounded the problem. I respectfully request the following actions 1. A thorough investigation into the root cause of the sudden failure. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
