Ford Junk rear glass

I used to work in the body shop of a GM dealership. The sales department came in a few times to find the rear glass busted out of Envoy's... they suspected vandalism and installed camera's.. To our surprise we found that they were just randomly exploding. So... we brought one into the shop and I found that the rear glass opens separate from the hatch, and when you closed it, the glass was actually resting on the metal of the hatch. I cut the hatch in the spots, reformed them... and a woman from DETROIT showed up to have the hatch flown BACK to GM to be scanned to re design the hatches... guess it was an issue their "engineer's" couldn't figure out lol.
