Irregular front tire wear on the inside of the tires down to the steel belts causing blow out and flats. Numerous wheel alignments have not fixed the problem. Why has GM not put out a recall on this dangerous issue? Loss of vehicle control when this occurs. Some one is going to get hurt or lose their life. I lost control of the vehicle the first time it occurred but managed to stay on the road.

My driver side door has flung open several times due to the window track coming unglued from the glass. It has happened at drive up windows, driving down the street/highway and even has flung open the door in a turn before. In the 2004-2006 Pontiac gtos both front side windows come detached from their forward most bracket that keeps the windows in their tracks. When this happens it allows the window to move and apply pressure onto the door release mechanism or linkage. There have been times where while rolling down the window it hits the linkage to open the door and the door opens. If going through a turn and rolling down the window the door can fly open and you can possibly fall out. Also if the door opens into traffic of some sort like in close quarters on a 2 lane road the vehicles door could be struck and injure the driver or passenger depending on which door is currently affected.
Feb 16th 2013 case # [redacted] my car was in for this service for a airbag fault light I was told that "found low voltage to various SRS components" and that according to a GM services bulletin inspection of the SRS wiring system behind the dash is needed. According to the dealer there is a GM service bulletin on faulty wiring harness being the cause. The airbag system could be not working. My concern is with said services bulletin I could not find anyone in the network of GTO owners clubs that were givin any notice of this. But I did find on these forums that one particular wiring harness comes in contact with a metal brace when the cars was converted to left hand drive for sale here that has caused fires. Would not this be a serious safety issue for which either GM or NHTSA would be involved in? …
