2024 Chevrolet Suburban Owner Complaints

While driving in the left lane of a two lane highway at highway speed of approx 65-70 mph the engine shut down. The instrument cluster said to “Press button to start engine”. I had no power. There was no throttle response. Luckily I was on a slight decline and was able to safely change lanes by coasting into the right lane then the shoulder. I was able to put the vehicle into park. The vehicle did restart. I took the vehicle to a Chevrolet dealer and was immediately told that there was an internal engine failure. I could have been rear ended or worse. This is a very serious issue. Upon doing some research, I found that the same thing has happened to many other people. This is very dangerous. Apparently this is becoming a major issue for the GM 6.2l eco tec engine. I hope that the next person this happens to doesn’t freak out and have an accident. If this happens to the wrong person, someone is going to lose their life.

The dealer stated the 6.2L engine had a bearing failure. When driving on 12-24-24 to a family event the dash lights all lit up and the car shut off. I was barely able to put the Suburban into neutral to pull off to the side of the road. Once stopped, the Suburban wouldn't start or even go into neutral so I could push it further off the side. This is extremely dangerous. My entire family was in the car on a very busy day (Xmas eve) without the ability to move the car in any way. Even when the tow truck driver arrived, he stated there isn't a way to force it into neutral. I also first learned about the 6.2L bearing issue from him. His 2023 Suburban was in the shop for the exact same issue. My 2024 Suburban has less than 13,000 miles on it before the failure!

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.

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.

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)

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.

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.

i pulled on to the road and i heard a loud knocking and my vehicle started skipping and wouldn't go. the lights on the dash lit up and said, "brake failure" and "emergency brake failure" and i had no brakes. I managed to coast into a parking lot. The engine light was on. I turned the vehicle off and waited about 5 minutes and turned it back on, The engine light remained. The first time this happened I was going down the road and the vehicle started sputtering, the emergency brake light came on the dash and the car shut off. It has a rough idle when you start it. I am terrified of this car. I have grandbabies in the car with me, Had i been on the highway either time i would have caused a terrible accident. The dealer says they can't get the car to do it so they can't fix anything. It has happened twice so you know it will again.
