2002-2009 Chevrolet Avalanche rear removable window (frame). Lower L/H side (passenger side).plastic frame subject to splitting in time with heat and separates and pulls away exposing tempered glass.tempered glass is now in contact with supporting frame and vulnerable to shattering from road vibration or worse, collision, thus injuring passenger(s) including infants in rear seat.my 2003 Avalanche frame began cracking early 2007 and is now has a 1 1/2 inch gap.I along with several thousand owners (research on internet), have brought this matter of defective materials to GM and Chevrolet attention only to be told "sorry it's not covered".I am very disappointed and rather angry that GM would not offer to repair or even replace these obviously defective window frame assemblys.according to my research with other owners up to 2009 model year, this defect still exists and owners that were fortunate to have theirs replaced if still under warranty have reported that the replacement has started cracking just the same! this is proof that GM has done absolutely nothing to improve/replace inferior materials that made this frame.

I have a 2003 Avalanche, I only have had the truck about a year. I truck have a shortage in the windows I have paid to have the windows fix, after they where fix about two days later they tells me I have a shortage in something that's causing my passage windows and seats to stop working. My windows stop working about 3 months after I got the truck, they told me that the windows were not under warranty. I need to know what can I do about this I have talked to a lot of people who are having the same problems. I am scared that its going to start a fire, it keep shorten out my fuels in my fuel box under the hood.
