Hatchback/liftgate problems of the 2003 GMC Yukon

I have a 2003 GMC Yukon. Several days ago I was going to put some items in the back end. After raising the rear hatch glass, I heard a popping noise. I couldn't tell where it came from at first, but when I tried to shut the rear glass, the right side of the glass just popped up. After looking at it closely I could see that the glass was separated from the right hinge. I had to pull the glass down by hand and align it while trying to shut the glass. My vehicle is a 2003 model with 55,000 miles. It is a second vehicle and stays garaged most of the time. I have a 1996 tahoe I use for hauling and odd jobs. I have probably opened the rear glass on the 2003 Yukon no more than a dozen times in the years that I have had it I usually open the entire hatch. Gm states that this problem is not a defect and is not covered under any warranty. Upon checking on line apparently hundreds of people have had the same problem. Gm refuses to do anything about it. The repair costs approximately $1000. 00. If this glass blows out or falls off while driving in traffic, someone could be seriously injured not only from the weight of the glass but from flying glass and debris. / this is definitely a manufacturing defect that again gm is ignoring until someone is injured and they are sued.

2003 Yukon back hatch glass exploded driving down the road. The glass was every where and cut my daughter in the back seat.
