While warming up my car to take my 5 year old son to school one chilly morning, my rear windshield just shattered and fell out. There were no cracks, no "dings", and no reason that should have occured. My 5 year old son was in the car and thank God that he wasn't cut when the glass went all over the place. I called the police out to investigate and he said that it could have been a maufacturer defect with the glass because it doesn't look as if someone tried to break in, so I checked online to see if there was some type of recall for the "faulty glass" but couldn't any but I did find another complaint where this happened to another HHR owner. You would think that a company like Chevrolet, would take more time to make sure that they are producing good quality products...think that they would take more pride in there work, since they are "The Heartbeat of America"...
