The rear defrost had been turned on as I drove to the store. I shopped for about 15 minutes and came out of the store and sat down on the front driver seat, which starts up things like the radio and I believe the defrost again. This is when I heard an exploseion, got out of the car to see what had caused the vibration and sound, and looked to find that the glass was shattered inward and there was a hole as if a brick had been thrown through it.  It was early in the morning and very few shoppers were in the parking lot, so I had a clear view of anyone running from the scene or hiding behind what few cars there were.  There was no item on the inside or outside of the car that would have produced any kind of hole.  The glass blew inward and a rear facing toddler car seat was impacted with small shards of tempered glass. There was no child passenger in that seat at the time of the shattering.  The local dealership reviewed the window when I took it in, and I suggested to them that it might be  defective defrost grid element, but they said they were not able to discern the origin of the problem, as I had cleaned up the shards prior to bringing in the car. The repair shop manager suggested it was a stray bb from a bb gun. I didn't see anyone close to the car in the parking lot, and the size and sound of the impact suggested more of brick at close range. Please see attached photo.   I took a picture and showed it to the local dealership manager, and also sent a report to VW Corporate with a similar picture, (only cropped to fit their document size requirement).  My insurance covered the repair service completed at our home on Thursday, July 14, and when they looked at the picture they definitely did not think that it was due to a bb  from a bb gun. To your bullet points, I did not notice any warning message prior to the explosion.","products":[{"type":"Vehicle","productYear":"2021","productMake":"VOLKSWAGEN","productModel":"ID.4","manufacturer":"Volkswagen Group of America, Inc."}]}]}
