2026 Chevrolet Silverado 1500 electrical 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.

While driving home from work, I pulled up to the stop sign at the end of the exit ramp. When I released the brake and pressed the gas pedal, my truck would not move. This immediately put me in an anxious state as I was expecting the vehicle to move. I checked my rearview mirror to make sure that there wasn’t anybody coming up behind me and put my flashers on while I tried to figure out what was going on. My eyes moved to the shifter next. I noticed that the vehicle was in park. I reached down to the shifter and tried to put the vehicle in drive, but it would not shift. I then hit the push-to-start button to restart the vehicle. After this, I was able to shift back into drive and finish my commute home. This was an unsafe condition as I experienced an unexpected loss of power. An approaching vehicle would expect me to be moving when the road is clear in front of me. I took the truck to the dealership the next day. My vehicle was repaired under warranty. The cause states "update 2810275 Serial Data Gateway Module Reprogramming with SPS." I did not notice any warning lamps or messages, but I also did not look at the instrument panel when this happened. My first thought was to check for approaching vehicle traffic and to put on my flashers. After I put on my flashers, I looked down and noticed the vehicle was in park.

I am reporting a serious safety-related malfunction involving my 2026 Chevrolet Silverado 1500 ZR2, purchased new on June 2, 2026. On October 31, 2026, at approximately 9,659 miles, my vehicle unexpectedly shifted into Neutral while I was traveling approximately 65–70 mph on the highway. The vehicle suddenly lost propulsion, forcing me to maneuver through highway traffic to reach the shoulder. This created a serious risk of collision. The vehicle became disabled and required towing. Following the incident, the Chevrolet application displayed two critical warnings: * Transmission System — Service Now * Ignition System — Service Now The application also recorded an unsuccessful starting attempt. I am concerned that this vehicle may contain a dangerous transmission, electronic control, or drivetrain defect capable of causing unexpected loss of propulsion at highway speeds. I request that the federal safety agency evaluate this incident as a potential vehicle safety defect and determine whether similar failures have been reported involving 2026 Chevrolet Silverado vehicles. I have screenshots of the vehicle warnings and can provide repair records and diagnostic findings when available.

The vehicle's power steering went out mid drive on the road after being driven about 2 miles. I was unable to turn the wheel. I attempted to restart the car at that point is when the engine would not start. The truck did not move in the middle of traffic. This is caused by some electrical problem. The dealer does not know what the issue is and they could not duplicate the issue. It is the second time it has happened to me.

Due to a manufacturing defect outlined in Gm internal bulletin #PIT6452E caused an electrical motor to stall, overheat, melting the plastic HVAC box and actuator doors and fill the cabin with a burning plastic smell. 50°+ heat above cabin thermostat setting was documented blowing extreme heat and burning plastic smell into the cabin. The electrical short, burning smell and melted components make the vehicle unsafe to drive. The heat issue has been reproduced by the technician. Documentation of this issue is currently not available in writing. Verbally I am told all this but Both Kendall Chevrolet of Marysville and GM customer care supervisors refuse to put in writing any mention of melting, burning, electrical short, safety hazards or that the vehicle is not safe to drive, even after multiple requests for written documentation. The only inspection I am aware of is from Kendall Chevrolet service department. No dashboard lights or warnings illuminated.

On October 17, 2026, approximately two minutes after driving smoke started to fill the cabin. It appeared to be coming from behind the rear seat area. I pulled over and could not find the source of the smoke so I drove back home and shut the truck off in my driveway. Almost immediately after shutting the truck off the rear glass on either side of the middle sliding window shattered, but stayed in place. The middle sliding window did not shatter. I then called Chevrolet road side service and the vehicle was towed to a dealership.

While driving, the vehicle shifted itself into Park without any driver input and the engine shut off. This has occurred on three occasions, first on May 24, 2026 at approximately 1,000 miles — three days after the vehicle was purchased new. It happened again at approximately 2,300 miles, and a third time at approximately 10,350 miles. Each occurrence happened at less than 10 mph — once while accelerating and twice while decelerating. No crash, fire, or injuries resulted. The vehicle was presented to an authorized Chevrolet dealer for this same defect on two occasions. On the first visit the dealer found no trouble code, could not duplicate the condition, and performed no repair. On the second visit, beginning September 22, 2026, no repair was performed and the vehicle remained out of service in the dealer's custody — 16 working days on that visit alone, 20 cumulative working days across both visits, as of October 13, 2026. A loaner vehicle was provided during both visits. The manufacturer has an open customer assistance case for this defect. The vehicle is not being driven in this condition; if it must be moved, it is moved by tow only. A vehicle that immobilizes itself in motion is a safety hazard to its occupants and to surrounding traffic.

I am reporting a safety concern involving my 2026 Chevrolet Silverado 1500 High Country equipped with the 6.2L V8 engine. I purchased the vehicle new on August 3, 2026. The engine has unexpectedly shut off on two separate occasions while the vehicle was still moving at low speed. The first incident occurred within approximately the first week of ownership, when the truck had less than approximately 1,000 miles on it. I was slowly driving through the parking lot at McB’s when the engine unexpectedly shut off while the vehicle was still moving. The instrument panel displayed “Press Brake to Start.” The engine did not automatically restart, and I had to stop the vehicle and manually restart the engine. The second incident occurred on September 18, 2026, while I was slowly driving through a parking garage. Again, the vehicle was still moving when the engine unexpectedly shut off. The instrument panel displayed the same “Press Brake to Start” message. The engine did not automatically restart, and I again had to manually restart the vehicle. I have a video recording of this incident. This vehicle is equipped with automatic engine Stop/Start. During normal Stop/Start operation, “AUTO STOP” is indicated on the instrument panel when the system shuts the engine off. During neither of these two incidents did the instrument panel indicate “AUTO STOP.” Instead, the engine unexpectedly shut off while the vehicle was moving, displayed “Press Brake to Start,” and required a manual restart. Both incidents occurred while maneuvering at low speed in parking areas. I am concerned that the same failure could occur at a higher speed, while entering or crossing traffic, or in another situation where an unexpected loss of engine power could cause a collision. The vehicle has also experienced intermittent electrical/electronic issues, including radio interruptions, remote-start problems, a “Key Not Detected” message, memory-seat/seat-recall problems, and an intermittent power running-

Components: rear vision camera display, front camera module/lane keep assist, and the center infotainment/navigation screen. The vehicle is currently with the dealership. Failures: The rear camera image intermittently distorts into a severe fisheye view, so I cannot judge distance or what is behind the truck when backing. Lane keep assist intermittently will not activate. The center screen freezes, becomes unresponsive, makes phantom inputs, overheats, goes black, and reboots on its own, cutting off navigation while driving. Safety risk: A distorted backup camera creates a risk of striking pedestrians, children, or objects when reversing a full-size pickup. Losing lane keep assist removes a driver-assistance safety function. The screen shutting off during active navigation has caused me to lose directions while driving in unfamiliar areas, which is distracting and has led me to get lost. Dealer confirmation: Reported to [XXX] at Milton Chevrolet ([XXX]) the day after delivery at 30 miles. Repair Order #XXX(XXX) confirmed the lane assist failure and found DTCs U3000 and U0131 stored in the Front Camera Module. The dealer cleared the codes and moved a toll transponder; no part was replaced. The touchscreen issue was not duplicated during a 10-minute test. The camera and screen failures continued, and I recorded multiple videos of them. Manufacturer: GM reviewed my repurchase request under Case #XXX and denied it on XXX. The vehicle has not been inspected by GM, and the defects remain unrepaired. Warning signs: Symptoms began immediately after delivery on XXX. No specific warning lamp was observed; the lane assist button light failed to illuminate when pressed. Current mileage is approximately 1,200.
