NHTSA Complaint #11554345 — 2021 BMW X3

Driving on a highway with occasional traffic lights, my 2021 X3 Plugin hybrid's sunroof's from glass cracked with a loud bang. I had it closed and the sun shade part also was closed. The loud bank also felt like an impact on my head and I felt in a bit of a shock like the time I was hit from behind with a shock and having to think. I first though it was a tire and slowed down to safely exit into a business parking lot to asses the situation. After checking the tires I noticed something on the roof. The glass was cracked and deformed in an upward direction. It was still pushing upward and a 4-6 inch section fell off and onto the top of the sun shade part. In safety, the loud shock caused a brief distraction on a highway going at least 50 MPH. Also if the sun shade was open some of the glass could have fallen on me. I searched online and found previous complaints about 'exploding sunroofs': https://www.carcomplaints.com/news/2018/bmw-exploding-sunroof-lawsuit.shtml. I did not see anything coming toward the car or notice other cars possibly slowing down or getting hit by something that would have hit my sunroof and bounced around in the traffic. I mobile detailer helped clean up the glass so I can drive on and able to take it to the dealer.
