SECOND time in less than 9 weeks that my rear window has shattered for no reason. The first time it was when I closed the hatch and this time it was when I shut the driver side door. Both times my car was in my garage and not running. I assume that all my windows were closed, I know they were this time, and usually are. This would appear to be some defect somewhere. I know the back windows are made to shatter easier than the other windows, but I think this is much too easy.
