Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“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”

Weather was cloudy, light rain in the 50's, late March in northern California, USA. Sunroof was in closed position and cars HVAC was not being used to create temperature or pressure difference.
