NHTSA Complaint #11498841 — 2018 GMC TERRAIN

I was driving at night with my daughter on a two lane highway with no traffic. There was a sound like a gun shot or explosion in the cabin of the car. My panoramic moonroof literally exploded. The glass shattered but did not fall into the cabin. Had the glass fallen into the cabin it could have cut or blinded us or caused an accident as we were traveling at a high rate of speed. No indicators went off as the moonroof has no such indicator. We pulled over to inspect the damage and immediately saw the glass damage. I have contacted insurance for repair. Upon research it seems that this is quite common for vehicles but not enough for any type of recall or service bulletin.
