Good evening! Sadly this is my first post on this forum but I have lurked a bit. I own a 2017 Sierra Denali which I bought in May of 2017. I was driving today and after using my remote start to start the truck (like i do often) I drove 5 minutes and then smelled smoke. I turned around and saw smoke pouring out from behind the rear seat on the driver side. I began to freak out and pulled over to get out but about 10 seconds after I saw the smoke and began to pull over I heard a loud bang like a gunshot. I turned around and my rear driver window shattered into thousands of pieces. It stayed in place but shot a decent amount of glass inside and outside of the vehicle. I am dropping the truck off at the dealership in the morning to have this diagnosed and this is clearly something that should not of happened. I only think what would of happened if I had kids or people in the back of the truck when this took place. Very disappointed right now and want this taken care of, but figured I needed to post this on here to inform all of you about this issue. I have researched this happening and it is a common thing on some Ford f150s but I havent seen to much about GMC.
