Owner complaint summary

Sunroof exploded while I was driving. No other cars around me, pretty day, not a very hot day. I’m driving along and suddenly hear a loud POP that sounded like a shotgun going off! I swerved, but thankfully did not leave the road. Shattered glass was contained in the cover of the sunroof as I didn’t have it open at the time. A huge hole is in my roof of my car! I called the dealership who said it was not covered under any warranty although I just got the vehicle in Feb of this year. He said I would have to contact corporate. I contacted corporate who said bring it in for an inspection. At the conclusion of the inspection on 10/8/24, they could not determine if it was a manufacturer defect or outside sources since they could not find a point of impact, because the glass was nearly all gone. I had to get my insurance involved. There was no warning whatsoever. The dealership said no recalls. It just exploded all of a sudden!
