NHTSA Complaint #11518259 — 2018 AUDI SQ5

While driving the rear half of the sunroof exploded. With no warning there was a sudden, very load "pop". The sunroof pane had completely shattered and was only held in place by the aftermarket tint layer that had been applied. The mesh shade that sits below the sunroof kept any pieces from falling on us while driving. Had the tint and mesh shade not been there, the interior would have been covered in glass. While we can't say with 100% certainty, we don't believe that any objects/debris hit the glass. The broken pane was on the back, downslope of the roof; if debris had hit it it would not have been a direct impact, but at most a glancing blow. We took the car to the dealer for repair. They immediately stated that it was due to rock/debris impact. The shattering does appear to originate from a single point in the glass, but there is not clear impact damage at that point. The origination point is smaller than a pencil eraser and is a square missing piece, of which there were many throughout the glass. I don't see the rough, crushing type damage I would relate to an object impact.
