when opening the Panoramic Sunroof while driving, the curtain would not retract and sagged. It totally blocks the rear view and there is no way to fix it while driving. also if you have a car seat facing the rear, the curtain would falls onto baby's face and potentially cause suffocation

Owner report 11610978 · 2024-08-26 (August 26, 2024)
My BMW's passenger side airbag malfunction light randomly came on and will not turn off. When I went to the dealer, BMW quoted apprx. $3000 to replace the seat sensor mat which they said probably got wet? No water was ever on the seat and no passenger sits there - just my purse. I feel this is a safety related defect after seeing numerous reports and complaints online and trying to fix the issue. The warning message also blocks other important information on my dashboard.

It is irregular and going over bumps seems to trigger it but yesterday as I was driving on a smooth highway with no vehicles nearby I heard a deafeningly loud crack sound. Then I noticed a tiny crack in the windshield. The sound was so loud that I considered it a potential accident inducing distraction as it really frightened me for a few seconds. Again it couldn’t have come from an outside projectile as there were no vehicles nearby and the highway surface wa…
