I have a 2017 Chevrolet Silverado double cab with power sliding rear window and defroster. When driving home I smelled burning wires and had smoke in the cab. Quickly shut off truck and opened doors and the rear window exploded. with only 31,000 miles and still under the 3 year 36k warranty GM will not stand behind it. I have owned at least 30 new GM vehicles and will not purchase another after this worst display of customer service I have ever seen. New window is $1000
