Blind Spot Detection problems of the 2022 Toyota 4Runner

We were driving down the interstate, no other cars, trucks, etc anywhere near us, and the sunroof of our 2022 Toyota 4runner spontaneously shattered. We were lucky that we had the shade closed on the sunroof when we experienced the gunshot like blast. We opened our sunroof shade and had glass fall down on us. We are so lucky that we had the shade closed and that there were no other cars near us, as this surely would have put lives at risk. We spoke to the Toyota dealership service manager where we bought the car the following day, which is about an hour from our house. He directed us to bring it in. When we arrived at the scheduled date/ timeframe, he informed us that it would take a day or so to do diagnostic tests- but he could not provide us with a car. (he knew that we were driving over an hour to bring it in. ) we obviously could not get home without a car. They directed us to try going to a different dealer. We went to a Toyota dealer on the way home, 1/2 hour from our house. They did not want to deal with the car and said we need to take it back to the dealer we bought it from. He also stated that he'd never heard of this happening and that it must have been a rock, which is similar to what the first dealership said. I've read on-line now that our experience is not unique to us. We are confident that we did not have a chip or crack in our sunroof prior to this happening. This incident definitely puts people at risk.
