Example complaints

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

“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.”

NHTSA complaint #11610978, filed 2024-08

“Consistent passenger restraint / passenger airbag failure warning. Took vehicle to BMW dealership and was told that the passenger seat must have moisture damage, causing the issue. There have been no spills or leaks in the vehicle. Quoted $2600 to fix. See attached. Vehicle’s safety in question.”
