2022 GMC Sierra 1500: brake failure

Filed Dec 21, 2025 · Brakes, Electrical · TX

1.)When driving the vehicle it will randomly shutoff while driving with loss of brakes and steering until it will randomly turn back on.The vehicle experiences intermittent electronic and drivability malfunctions. The issue appears to involve one or more vehicle control modules and/or electronic systems. At times, warning lights and system messages appear, and vehicle performance is affected. The vehicle is available for inspection upon request. 2.)These failures create a serious safety risk because they occur without warning while driving. The vehicle may lose normal functionality, display multiple warnings, or behave unpredictably. If this occurs in traffic, at speed, or while maneuvering, it could increase the risk of a crash or leave the vehicle stranded in an unsafe location. Furthermore on 3 separate circumstances I came close to crashing the vehicle putting at risk lives in the vehicle and outside. 3.)The problem is intermittent and has been difficult to reproduce on demand. I have taken the truck to the dealership multiple times. The dealership has stated that because the issue is not actively occurring when they have the vehicle, they have been unable to duplicate the concern and have instructed me to continue driving it until the issue happens again. Despite this, the problem continues to return during normal use. 4.)The vehicle has been inspected by the authorized dealership on multiple occasions. To my knowledge, it has not been inspected directly by the manufacturer, police, or insurance representatives. 5.)Intermittent warning lights and system messages appear, including at times a check engine light and other alerts. These warnings may appear suddenly as the truck shuts off and then disappear after the vehicle is turned off and restarted. Another thing to point out is that the audio and turn signal chime cut off randomly. The issue first began while the vehicle was already in normal use and has continued to reoccur since.

I was driving the vehicle with my 4 year old daughter and experienced a complete brake failure. The dealership responded by replacing the master cylinder (the truck only has 16000 miles on it). Upon receiving the truck back from the dealer, another brake failure occurred. This is a dangerous vehicle and GM has done nothing to make it right with me.

When I initially started the vehicle, I noticed the parking assist would not turn on. No warning lights or messages were displayed so I didn't think much of it and continued on driving. Approximately 5 miles down the road while traveling around 45 mph, I came upon a stoplight with other cars waiting. I pressed the brake to start decelerating and the pedal went all the way to the floor and vehicle did not slow down/decelerate. The check engine light, ESC, trailer brake, and brakes warning lights/messages then illuminated. I was approaching the vehicle in front of me quickly so, to avoid a rear end collision, I swerved into the shoulder and was able to coast through a right turn and on to a side street where I eventually coasted to a stop. I narrowly missed a major collision and was fortunate that there was no cross traffic approaching when I turned on to the side street. This could have been catastrophic, especially if pedestrians had been in the area. After stopping, I restarted the truck and the brakes seemed to work, however, the warning lights remained illuminated. I drove slowly to the nearest dealership. They replaced the electronic brake control module. Truck has approximately 20,000 miles on it and is well maintained.
