2026 Chevrolet Silverado 1500 brakes problems

Filed Nov 4, 2026 · Acceleration, Brakes · RI

I was traveling on a highway on-ramp and when I accelerated to get to normal driving speed, every light on the dash blinked and had a full brake failure. No ABS, no pressure on the pads, and the vehicle was limited to 60 mph. I narrowly avoided multiple accidents. This came with zero warning and the truck had less than 12,000 miles on it.

My 2026 Chevrolet Silverado 1500 Trail Boss, equipped with the 5.3L V8 engine and 10-speed automatic transmission, intermittently experiences a complete engine stall while the vehicle is still moving. This condition typically occurs following an extended period of driving, during braking and deceleration at approximately 1 to 5 mph. The vehicle locks the emergency brake and the engine stops. This happened in stop/go traffic as well as in my neighborhood. As the vehicle approaches a complete stop, the engine begins to struggle, with noticeable hesitation and a reduction in engine RPM, before shutting off completely. When the engine stalls, the transmission automatically shifts into Neutral, requiring me to restart the engine before I can resume driving. This is not normal automatic engine start/stop operation. The issue occurs even when the automatic start/stop feature has been manually disabled. The engine shuts down unexpectedly without driver input or an intentional shutdown command. The intermittent nature of this malfunction makes it difficult to predict when the vehicle will stall. The unexpected loss of engine power while the vehicle is moving creates a significant safety concern, particularly when braking, turning, entering intersections, or maneuvering in traffic. The vehicle could become temporarily disabled in an active roadway, increasing the risk of a collision. I have identified reports from other owners of 2026 Chevrolet Silverado 1500 vehicles describing similar unexpected engine shutdowns during low-speed operation, including instances where the transmission shifts into Neutral and requires an engine restart. The cause of this malfunction has not been determined. I am requesting that the federal safety agency investigate whether this condition represents a broader safety defect affecting 2026 Chevrolet Silverado 1500 vehicles equipped with the 5.3L V8 engine. I am concerned this could happen on the highway or cause an accident. Dealer cannot replicate...

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. GM has published Preliminary Information bulletin PIT5689N, "No Restart after an Auto Stop Event / No Crank," covering 2020-2026 Silverado 1500 trucks. It cites a loose or broken engine ground strap as a possible cause. This vehicle is 5 days old and the defect appeared within 116 miles of delivery. I am disabling Auto Stop manually at every startup until the vehicle is repaired. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The vehicle was then driven in LIMP Mode. The vehicle was taken to a dealer and was diagnosed with a brake control module failure, which was caused by an incorrect software version that had crashed the module.

While driving in a parking lot. Barely applying throttle to move straight forward not turning or driving on a rough road the truck completely shut off all screens went blank and I wasn't able to accelerate. I was able to restart the truck, shift into drive and continue but took a few seconds to realize the issue and properly restart the engine. Thankfully this occurred while in a parking lot without anyone behind me but this is a real concern for me now driving on streets/highways with other vehicles around. This truck was purchased brand new has never been off road and has just over 3,100 miles. There were no warning lights before or after this incident.

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 the federal safety agency because I am concerned the underlying safety defect remains unresolved and could represent an early instance of a broader defect.

The contact owns a 2026 Chevrolet Silverado 1500. The contact stated that while driving at 70 MPH, there was an abnormally loud pinging sound coming from the engine. The vehicle lost motive power, the brakes and the steering wheel became inoperable. The message "Depress Start" was displayed. The vehicle was towed to the local dealer, where it was initially diagnosed that the battery failure was unsoldered. The vehicle was repaired, but the failure recurred. While being test-driven by the mechanic, the vehicle stalled. After further investigation, it was determined that the engine needed to be replaced due to the main bearing failure. The manufacturer was notified of the failure, opened a case and informed the contact that a case worker, near his location, would contact him in 24 hours. The failure mileage was approximately 9,025.
