There are 5 owner-reported powertrain & transmission complaints for the 2024 Chevrolet Suburbanin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Upon stepping on brakes, the car shifts into Neutral and says “press start Button again.” This happened to me 2x now.
Both front CV axles have had to be replaced multiple times. Less than 70,000 miles on the vehicle.
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.
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)
