Rear windows obstructed. Windows will not roll up. No children, model 1999 Alero. I can say this window has not been lowered 100 times in the last 6 years. It stop working in 2006. I decided to see if it was a serious defect by going on the internet, and I see their is a problem GM will not fix without a investigation if you have a child, the safety lock serves no purpose. The window just falls down at any given time. This will any small child or animal to exit through the window.

The passenger window fell off track all of a sudden while I was driving on the highway. I pulled it back up and it continues to fall at dangerous time. I don't have the money to get it repaired. It should not have happened as it is.

The driver's side window came off track and ended up in the bottom of the door. In the process, the clips which hold the glass on broke off, the glass broke, and the window regulator broke. This is not the first problem I have had with this window, but by far the most expensive to repair.

On the way from work one day after a rain shower, I use the power driver window to roll down the window for some fresh air. When I power rolled up the window, there were deep scratches on various places on the window. Tsb#98831520 took to dealer service dept to repair under warranty. It was fixed but three days later it was scratched again in the same manner. Took back to dealer service to repair...okay. Later other three window had scratches due to use. All replaced, but now three of the four windows (passenger front and rear and driver rear) have scratches. There was a tsb issued for this problem, but the problem was never fixed. Now the manufacture warranty has expired. Contacted manufacture for assistance but no help offered.

Feel brakes on vehicle are defective requiring multiple repairs as a result. Do not think they are safe even after repaired given the repeat frequency of subsequent repairs. In addition, glass panes on all four side windows have long mechanical scratch marks, which sometimes catch glare of sun/headlights when looking out those windows during lane changes. Scratches appear to be result of defective window housing/mechanicals.
