GMC DOOR LATCH User Comment / Complaint

About two years ago while i was trying to close the glass rear hatch on my 2003 chevrolet trailblazer it exploded in my face. i was cut on my hands, face, and got glass in my eyes. i went directly to the dealer (arrow chevrolet, now called sunrise chevrolet, in midlothian il.) the service dept. looked at the damage and said they never saw anything like that, (i found out later that it is common) they sent the vehicle out to a "window repair shop" to have the glass replaced. when i got the car back, i noticed that the window was not aligned properly; the service dept. looked at it quickly and told me that it was fine. three weeks ago while driving down the interstate at 70 mph a loud vibration came from the glass window hatch, as i slowed down the high mount rear stop tail lamp assembly, which is a large fiberglass body piece as wide as the car and 3 feet across flew off my car striking a car in back of me. i pulled over and so did the other driver, the other driver was very shaken as so was i. slight damage to the hood and the bumper of the other car and he said that it was ok since the car was old. my car now is missing a large piece of the body and the third brake light. it was run over by a truck... the window company that replaced the rear hatch window did not affix the panel properly to the window; i have seen may complaints on other web site that the factory install and the double face tape that is used malfunctions all the time, please help me, we are dealing with two issues here, the rear window exploding and injuring me and the faulty double faced tape that is used to secure outside parts to the car. in addition, the illinois state police stopped and told me that they could have given me a ticket for driving an unsafe vehicle but they gave me a pass and told me to write to you and send them a copy of my letter.
