Was driving at highway speeds and just topped a hill without any other vehicles around, no overpasses, no one on the side roads, etc. When the sunroof spontaneously exploded. Had been driving for about 20 minutes without any incidents before this happened. Not only did the glass blow out but the shards left hundreds of scratches to the paint on the roof bad enough to need to be repainted. When it happened the sound of the glass exploding was extremely loud. That morning was the first morning we had frost on the vehicles since we bought it new.
