2018: “I was driving on the highway and the sunroof exploded out of no where, Bmw said a rock hit it or something but I am 90% sure a rock didn't hit it. Did not see anything fly up towards the car. It sounded like a gunshot went off in the car and glass showering all over you because I had the shade open. Luckily it did not get into my eyes to cause another accident. Glass shattered upwards and from doing research it looks like it's a common problem”
