My truck trailer Brake system continues to come on and my doors are locking and unlocking. It has my 4x4 trans rubbing as well. Its a non stop issue everytime I get into my truck it does this and it happened out of no where. I had this truck a little over a year now
Randomly all electronics shut down engine stalls and lane assists wont let me turn wheel while driving in road. Normally at slow speeds. Get random warning lights that go away after seconds. When I activate a window switch all the electronics turn off and on. This happens randomly.
Driving at approx 55 to 60 MPH with rear defrost on. Began to smell a burning/electrical smell, and within 90 seconds heard a loud bang. Rear window (stationary piece on drivers side) had shattered. Smell presumably coming from the rear window defrost component. No warning lights or messages on the truck.
The contact owns a 2017 GMC Sierra 1500. The contact stated that ‘hood open” was displayed on the instrument panel. The contact inspected the hood and confirmed that the hood was securely locked. The vehicle was not taken to be diagnosed. The manufacturer was not informed of the failure. The VIN was not available.
The vehicle was in motion on a city street, when the vehicle completely powered off. The steering wheel locked. This occurred on 11/22/2020 and 11/23/2020. The following message is on my dashboard 'steering assist is reduced drive with care.'

Wiring, modules, batteries, charging, infotainment and driver displays — NHTSA's broadest heading. Owners choose the heading when they file, so it says which area of the vehicle the complaint is about, not which part failed.
