On [xxx], at approximately [xxx], I was driving my 2026 Chevrolet Silverado 1500 rst (5. 3l v8, 4wd), leased new on [xxx], with about 122 miles on the odometer. I came to a complete stop at a stop sign on an uphill grade at [xxx]. The auto stop/start feature shut the engine off while I held the brake, as designed. When I released the brake to proceed, the engine did not restart, and the truck rolled backward down the grade. The instrument cluster displayed "press start button. " I pressed the start button, the engine started, and I released the brake again. The truck again rolled backward, and the cluster again displayed "press start button. " at this point, the vehicle was in park and with the parking break engaged. I pressed start a second time. I released the parking brake, shifted into drive, and was finally able to proceed. In total there were 2 failed restarts after an auto stop event, 2 uncommanded rollbacks on an incline, and 1 automatic parking brake engagement. No collision occurred. However, the truck rolled backward toward another vehicle behind it with no engine power, and I had to restart it twice while stopped at an intersection. This is a serious safety hazard in traffic, especially on hills.

On xxx, my Chevrolet silverado experienced a sudden, severe loss of normal braking shortly after I dropped my child off at school. When I attempted to stop at a stop sign, the vehicle would not stop normally. The brake pedal remained firm, but braking effectiveness was drastically reduced and required extreme force. The dashboard simultaneously displayed multiple warnings involving the brake/abs system, esc, steering-column lock, and trailer-brake system. Onstar generated a diagnostic/safety report identifying fault/error code p062f. The vehicle then entered a reduced-speed/limp-mode condition. I was extremely fortunate this occurred within approximately one mile of rick hendrick Chevrolet of [xxx] and with little traffic around me. I was able to reach the dealership without a collision. Had this occurred at highway speed, the inability to stop normally could have resulted in a fatal crash. The incident also occurred immediately after school drop-off. Had I used the normal car line instead of parking and walking my child inside, this failure could have occurred among stopped vehicles while children were actively exiting them. I immediately brought the vehicle to rick hendrick Chevrolet. Despite the seriousness of the event, I do not believe the cause was adequately investigated. To my knowledge, a computer/software update was performed and I was essentially told to “let them know if it happens again. ” they also asked what I was towing - nothing. I questioned whether an electrical fault or short could have caused the multiple simultaneous failures, but I am not aware of that possibility being investigated. Because another occurrence could cause serious injury or death, I refused to continue driving the vehicle and traded it in. I have now learned that the same vehicle is being offered for sale again. I am reporting this to NHTSA because I am concerned the underlying safety defect remains unresolved and could represent an early instance of a broader defect.

I am writing regarding an ongoing and serious issue with my 2026 Chevrolet Silverado 1500 rst 2. 7l that continues to occur despite multiple visits to the dealership. Recently, as I was leaving my house, I entered my truck and started the vehicle as normal. Immediately after startup, approximately eight warning lights and system failure messages appeared on the dashboard simultaneously. The warnings included the check engine light, abs warning, brake system failure, service steering column lock, service traction control, service esc, service brake pad monitor, and trailer brake disabled warnings. At that point, the truck became undriveable. Although I was able to shift gears, the vehicle would not move properly in either drive or reverse. Due to the severity of the issue, I turned the truck off and left it parked overnight. The following day, all warning lights and messages had disappeared completely. This situation is extremely concerning because the vehicle appears to fail randomly without warning. I no longer feel safe driving the truck, especially with my children in the vehicle, because I fear it could stop functioning again at any time and potentially create a dangerous situation. I have already taken the truck to the dealership multiple times regarding this issue. However, I have repeatedly been told that they cannot properly diagnose or repair the problem unless the warning lights are actively present at the time of inspection. Since the issue is intermittent, this has made it very difficult to get the truck repaired, even though the problem clearly continues to occur. I am requesting that this matter be taken seriously and investigated further, and because this is a new truck that barely has 7,833 miles on it. As this appears to involve critical safety systems including braking, traction control, steering, and vehicle drivability. I depend on this truck daily and need a permanent resolution to this problem as soon as possible.
