Frame And Members problems of the 2002 Chevrolet Suburban

I was driving on the highway when I heard a blast of air like a tornado or hurricane in my car. Papers and things in my car started flying. When I stopped I discovered that the rear window had seperated itself from the frame at the top and was now open by an inch. The window is designed to open from the bottom with a latch. The two hinges at the top of the window had now also snapped broken from the window, leaving only the sides attached. This is a very large window and could have totally come off in traffic causing great harm to others. If the window had been open as it is also designed it would have blown off. I have since found that the collision repair place I used said he had another just like it the week before. In trying to replace the window with another used one he found that the adhesive was also starting to do the same, therefore it was necessary to replace it with a new one. In fixing the window the collision expert showed how easy it would be for the manufacturer to fix. It needs both sides of the hinges bolted. I do feel this should be addressed to save others harm. I have also saved all parts personally for any/all inspection.
