The contact owns a 2024 Chevrolet Silverado 1500. The contact stated that while driving at 75 MPH, the engine shut off without warning. The contact safely coasted to the shoulder of the road and requested assistance from 911 to secure the vehicle from oncoming traffic. The vehicle was then towed to a dealer, where a diagnostic assessment confirmed a total engine failure, requiring replacement. The contact had previously taken the vehicle to a dealer for NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the inspection yielded no visible issues, and the recall was marked as completed. The vehicle remained at the dealer and had yet to be repaired. The manufacturer had not been notified of the failure. The failure mileage was approximately 25,500.

Transmission has shifting issues (hard shifts) . Vehicle is available for inspection upon request. Safety could be an issue if the transmission fails while driving that could cause harm to the vehicle driver and put others at risk. Vehicle is scheduled for inspection however the dealer is very backlogged.

Oil cooler failed and truck was at dealer for a month over winter. Now June 20th transmission failed and there is no timeframe on the valve body. I am still making payments on this truck and no dealers have a timeframe.

I was driving down the XXX Expressway Sunday, XXX, with my children in my vehicle. This is a very heavily traveled highway in [XXX] with heavy traffic. My 2024 Chevy Silverado 3500 Diesel HD Truck with 25,500 miles suddenly started throwing multiple codes, lost power, and steering. Fortunately I was able to "roll into" the emergency lane while muscling the steering in that direction and engaged the emergency brake. My other son was following shortly behind me in his vehicle and pulled over to assist us about 30 mins after my truck was sitting stalled in the HWY. He parked his truck behind mine, put on his hazards, and we were transferring gear from my truck to his truck. At this point my 2024 Chevy HD Silverado Diesel started rolling back on it's own and nearly crushed my son's friend. The parking break was on and it suddenly released on it's own. It took 3 grown men to stop it from crushing my son's friend. The force was so strong that when he lifted his hand to try to stop the truck from rolling, it broke the right rear tail light. He could have been crushed between our two trucks from this situation. I have never been notified by GM of any recalls, however, the truck had to be towed to Ferman Cheverlotte service on Adamo Dr, Tampa Fl and is currently sitting on their lot. I was told by the service tech Michael Stevens that the vehicle had several open recalls that they would address but did not offer any information about what could be wrong. After searching online, I found that GM IS aware of this issue and sent several service bulletins about this exact problem. I had contacted the Ferman service center the week before to bring the truck in because the AC was out and made an appointment for service on Tuesday. The day after I made the appointment my batteries died and had to be replaced by AAA.It is disturbing to know GM and FERMAN Service centers are aware of this safety issue on these HD trucks and never informed me, the consumer.
