Hello..I have a Scion XB 2006..it is still like new..only 10K miles..that being said, I went outside last night (after midnight) to get something I left on the front seat. When I shut the door, the back glass just shattered! It sounded like someone was throwing gravel at the car! What a mess..I have never seen anything like it. It just happened "spontaniously"-no objects hitting it or anything, and, it wasn't hot outside! Anyway, I am covered and Safelite is repairing it next week. Has anyone ever heard of this? ThankS - Rose in GA
