The rear window on my 2017 GMC Sierra shattered unexpectedly without any impact. The vehicle had been remote started in very cold weather and the rear window glass suddenly shattered while the truck was parked. There was no rock strike or external damage that would explain the failure. I later learned about GM Customer Satisfaction Program N192265660 regarding rear window defroster thermal events affecting certain 2014–2019 GMC Sierra and Chevrolet Silverado trucks. Based on the sudden failure and the conditions at the time, this appears consistent with that issue. The Auto Rear Defog feature in the vehicle settings was turned off, however the truck had been started using the remote start feature when the glass shattered. Photos of the shattered window are available. I am submitting this report because the rear window defroster system may cause the glass to overheat and shatter unexpectedly.

While the 2017 GMC Sierra was warming up via remote start, I noticed a smell of smoke as I walked by the passenger side of the truck. Then I heard a loud bang as I was walking around the rear of the truck. As I entered the truck from the driver's door I saw the back window, passenger side, shattered. The vehicle was then turned off. According to our dealership the vehicle was looked at under recall N192265660 and deemed safe in May of 2020. A call was placed to GM who said the recall expired in 2022. An offer was made by for payment assistance by the GM representative but could not say how much until we pay the dealership for a diagnostic. This is a know issue by GM. The location of the shattered window is situated inches behind where my child's head would have been had she been in the vehicle.The smell of smoke is extremely concerning because where there's smoke there's fire.

Started car via remote start. When I went out to the car I noticed smoke in the cab. I then observed the rear power slide window to be smoking and further discovered the rear defroster wires the be smoldering creating considerable smoke. The tempered glass then began to spider and completely cracked. There is a former recall on the rear slide window involving fire hazards and the wiring components. It should also be noted that our 9 month old’s car seat is directly below the window and defroster wiring were the smoldering took place. No warnings lamps were observed prior to the incident.

Driving in town going 20mph and the truck shut down not allowing for braking or gas and the steering locked up. Placed the vehicle in neutral, shut the truck off and turned it back. Was able to continue driving. Attempted to have the dealership we bought it from run a diagnostic and the battery was replaced but it continues to shut down at random times. Took the truck to a local auto shop after this happened again, another diagnostic was run, I am waiting the report to confirm what was done.

Reverse lights stay on. Causing the battery to drain. The fuse box under the hood is prone to go bad. Even with no corrosion. GM knows this and has not fixed the issue. Its a common problem going back many years. The need to upgrade the fuse box under the hood & the wiring harnesses. My taillight harnesses were completely burned up. The truck could of caught fire. This should be a recall. Instead GM wants to take the money they are making off all the fuse boxes they are selling.
