2024 Chevrolet Suburban Powertrain (other) Problems

Ongoing observation where the 10L80 equipped often shutters or struggles to determine the appropriate gear, often hesitating on acceleration. This has caused numerous scares when entering onto roadways. This has been a recalled issue on 2020-2022 models, but the issues persists with this year model (2024). The dealer has said it is a common experience among owners and expects a recall, but has said they can do nothing otherwise until then. The transmission has been properly cared for and serviced, following the GM recommended maintenance interval.

The contact owns a 2024 Chevrolet Suburban. The contact stated that while driving at various speeds, there was an abnormal sound coming from the rear of the vehicle. The sound became significantly louder while driving. The contact stated that while driving at highway speeds and depressing the brake pedal, the vehicle felt like the rear wheels would lock up. The contact stated that the rear wheels locked while reversing, causing the vehicle to jerk abnormally. The vehicle was taken to the dealer, where it was diagnosed with rear axle failure. The dealer determined that the rear axle needed to be replaced. The private warranty company declined to cover the repair unless the rear axle had completely failed. The manufacturer was notified of the failure and declined to cover the repair because the vehicle was no longer under warranty. The contact had previously reported the failure to the dealer, who could not duplicate the failure while the vehicle was still covered under warranty. Additionally, the contact stated that upon engaging the air recirculation, the contact smelled fumes. The vehicle was not repaired. The failure mileage was approximately 23,000.

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)
