I was driving on I-405N at around 70 mph, the pace of the very light traffic that night, and there were no other cars within 100 yards in front of me. There were no overpasses or pedestrians anywhere nearby. All of a sudden, my sunroof spontaneously shattered! a large piece of it broke off and then was blown backwards, bouncing off my roof and trunk, scratching the paint. The person driving behind me drove over the sunroof and shards of glass. Luckily, I had my sunroof sunshade closed which prevented the shards of glass from showering on me when the sunroof exploded.

The BMW 3 series (mine included) identified by chassis designations E90, E91, E92, and E93 (all us models) have a known defect regarding automatic exterior mirror movement when unlocking the vehicle doors using the key fob. The mirror movement occurs regardless of which key fob is presented to unlock doors. A single keyfob unlock process can trigger innumerable exterior mirror positions. The unsuspecting driver who does not check both his/her driver and passenger side mirrors prior to driving the vehicle will be required to set the proper mirror positions while driving or leave them maladjusted until the next stop, impairing their ability to see vehicles adjacent or oncoming vehicles from the rear, including emergency vehicles. BMW has issued a service bulletin regarding this defect. However, only cars with existing manufacturer warranties are repaired if this issue occurs. Ref BMW si B51 36 08 the problem has been linked to corrosion of mirror motor electrical connectors. It is also plausible that all electrical adjustment of the exterior mirrors would be rendered an impossibility if the problem escalates.
