NHTSA Complaint #11420948 — 2021 BMW X3

I was driving on I-10 W in Phoenix Arizona with my husband on Thursday June 10th, 2021 when we heard a loud glass shattering sound. I immediately looked for a place to park or exit. I thought maybe someone was shooting at our vehicle in the freeway. I tried changing lane as quickly as possible to exit into Baseline Rd and parked at a parking lot. I was so scared looking at the mirror to see if anyone was following us. We walked around the SUV checking the windows, windshield but no broken glass or holes on any of them. I thought of the moonroof/sunroof so I hopped on the BMW to check the moonroof/sunroof. The sunroof shattered into million pieces. I didn't see a warning on the dashboard. We didn't go under any bridge between Elliott and Baseline. There were no big trucks around us either. It shattered without warning. This happened between 11:00am - 11:30am, light traffic. My BMW X3 2021 is brand new, only 20 days old and approximately 400 or so miles. I believe it's a safety issue with the glass or moonroof/sunroof structural defect. Definitely a highway safety hazard when it shattered out of the blue at 65 miles an hour. Luckily we didn't have the sunroof open. It's extremely hot this time of the year in Phoenix. I decided to drive it immediately to The BMW dealership. The service department checked it out and the Service Advisor told me to call my insurance. I contacted the BMW Warranty Department and the Manager told me it is not covered under warranty. She was making the assumption that a rock hit the sunroof. I contacted BMW Customer Service and reported it. The BMW Customer Service Executive called me back today and pretty much said the same thing as the Warranty Manager. BMW and NHTSA should investigate the occurrences of Sunroof shattering without any apparent reason for the safety of drivers and passengers plus all the other drivers on the road who may get impacted by such an occurrence.
