Rear windshield popped out!

[AmazinglySmooth]

We are about 1/3rd of the way home on our 1200 mile trek across America. I opened the rear windshield with the key fob to grab something. When I closed it, it didn't close. Instead, the windshield flew up onto the roof! It had slid off the hinges!!! How could this have happened? Fortunately, my wife and I were able to wrangle it back onto the hinges, but what holds it on the hinges?

I suspect the dealer didn't reinstall some clips, but I don't know. One Christmas, the rear defroster solder joint failed, and the dealer put a new rear windshield on. Regardless, I'm very disappointed. I hope it didn't scratch the roof. What is even more amazing is the amount of time between the repair and today.

This is in my 2011 Yukon XL Denali.

I'd have to imagine this being the case. Never heard of this happening before.
