| Seat Belt problems |
My car randomly started throwing an error for a failure with the passenger restraint system. From what I have read it has something to do with the oc3 mat in the seat that detects if there is an occupant, and if the weight of the occupant is considered to be that of an adult, so the airbag does not deploy in the wrong circumstances, which is potentially dangerous to anyone that may ride in the passenger seat. There has been an extended warranty, and recall for previous years of e90 Bmws, but 2009 may not be included, even though the seats should be the same. I plan on contacting the dealership for further investigation, but I know I cannot afford to have this safety feature fixed out of my pocket at this time. Thank you for your time.
I turned my car on an out of nowhere a seatbelt and airbag light came on. I did not get into a bump up or disconnect any sensors it just popped up one day.
Randomly while driving and sometimes when stationary my car's electrical system started going haywire including my gauges and the passenger airbag as well some other safety features with tthe seatbelt were disabled with & without a passenger in the car. I keep getting a warning screen that tread as follows: "restraint system malfunction. Fault in passenger-restraint system affecting airbag, belt tensioner or belt-force limiter. Continue to wear the safety belt. Have the system checked by the nearest BMW center. " after looking online it is a common problem but for some reason my VIN isn't included on the recall.
When a passenger is belted - with car running/driving - an alarm comes on - basically not recognizing when belted. Also the inactive airbag light is not on. When no passenger, the car used to light up the 'airbag not active' - it no longer shows that (light is always off) whether passenger there or not.
After a personal investigation into this issue, BMW seems to still deny that my model has the same issues described in the recall. "restraint system malfunction!" appears on the car every 20 seconds frighting drivers and passengers the airbags and seatbelts might not work. This is an american car curently in canada.
My vehicle suddenly displayed a passenger restraint system malfunction message following someone sitting in the seat. Everything appears to be in full working order except whatever is causing the malfunction.
Issue: when seat unoccupied, will receive seat belt warning as if a person is in the seat. Issue: when passenger is in seat, airbag and seat belt light comes on, with warning on the display that there is a restraint system malfunction. Defect with front passenger air bag seat occupancy sensor mat, there are several recalls for this issue in different years/models. My year is not covered for the current recalls, even though its the same exact issue, and likely the same mat and/or seats. Example recalls: 17v-428 13v-564 17v-605.
