Ford Junk rear glass

Anybody have this problem? for the second time now the rear glass in my wife's POS*&T 2006 Ford Escape exploded without a reason. What a mess! Last time the truck was under extended warranty. I know I am going to have a fight on my hands this time out. I looked on some Ford sites and the problem is pretty common. Ford wont admit there is a problem. What a joke. God help them if my son was in the car!!
Thanks for the rant.
