Wiper problems of the 2017 GMC Sierra 1500

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 using the rear defrost my daughter smelled burning. Moments after the smell the rear window exploded. This is a sliding three part window and it shattered on the passenger side. My daughter was hit by the exploding glass.

My rear defrosters shorted out causing a small fire and causing the window to explode. The recall for this issue has already been performed on this vehicle. . .

Started my truck to go to the store. When me and my son got in we could smell like hot plastic burning. Figured someone was burning trash so we proceeded to the store. About a mile down the road it sounded like someone fired a gun inside the cab of the truck. So being a combat veteran it triggered me! I instantly swung for the back seat thinking someone was back there and noticed the rear sliding window on the drivers side had blown and shattered. I found a recall online that gm had put out about this specific issue happening. So when I called varney GMC of bangor maine. They told me the recall had ben done at 97000 miles and there was nothing they could do unless I paid for it….

Back window started smoking next to handle to open sliding window then shattered then started falling out. I was moving and in in reverse backing up when this happened. (left section of back window).

Rear solid/heated window exploded while stationary in the drive way.
