As I was making a left turn in an intersection at 5:30am my rear glass window burst and all the glass shattered leaving glass on the four sides only. Inexplicable how it happened, my first reaction was too look back and see if anybody had hit us, but when I looked through the rear/side mirrors there was no cars behind us or near us. The same morning I called the dealership and they towed my vehicle to the shop for a transmission recall, per the dealer they would not cover it under the warranty due to General Motors had no other vehicles reporting the same incident. I feel it should be looked at because I'm sure many 2012 Chevy Sonics have it as a defect. With so many recalls I wouldn't doubt that the windows are being recalled as well.
