Four problems related to air bag light on have been reported for the 2009 BMW 328. The most recently reported issues are listed below.
It started happening here and there, while no one is in the passenger seat, it is saying seat belts need to be on and an airbag light, after a little while of driving the airbag light sometimes goes off but seat belt light will stay on. Even when someone is in the seat with their seat belt on - both of those lights are on seat belt and airbag. I'm scared if I get in an accident the airbags wont deploy. I'm also seeing I'm not the only BMW with this issue. Why is there no recall when this can cost someone their life. No cars airbag system should just go.
Air bag light has came on, when I was backing up, I hit a garbage can. I was told it was the front driver side but no air bag deployed.
Seat occupancy detector faulty. Passenger airbag light came on so took to BMW dealer. (as an aside this occurred shortly after (WI 3-4 months) air bag replaced due to takata airbag recall). Told related to seat mat sensor, which was under/in passenger seat. Not told that could disable front air bag. Not told that multiple BMW models including 2006, 2007, 2008, 2009 and 2010 models have same defect, including the 3 series, and the 328i model, and the 5 series,and in particular, models with climate or sport seat (like mine). Told replacement cost well over $1,000. Declined service thinking it was just a defective seatbelt notice issue (and seatbelt worked), not realizing impacted safety. When air bag light continued to stay on and came on more frequently, took car to a non-BMW repair shop for a second opinion, which told me this is a very common issue with Bmws and that defect prevents passenger air bag from deploying. Called BMW dealership back and restated what other repair shop had said and this time service person told me may be subject to recall, but when he looked up VIN number this particular model not included. This time BMW service person also told me that issue will deactivate air bag deployment. BMW refused to repair without charging full amount. Called BMW customer relations and services at BMW USA to complain and while acknowledging all of these issues with other models/years claimed they could not assume the same issue occurring here. Really??? this is an issue that can significantly increase risk of injury in the event of a crash. BMW is aware of the issue and refuses to do anything about it. Shame on BMW.
We bought the car in 2009, at the time the milleage only around 30000 miles, seat belt and air bag light on, in 2012. We brought to BMW dealer, the service tech stated that we have to pay certain amount of money to diagnose it, and to change both of it will cost us thousands of follars. Please replace it. It will cost us thousands of dollars. Until today we still have they same problems because we can not afford it. I got some information from other people that many owners of BMW have the same problems. I am concerned with my daughter's life. She is driving it, we just hope nothing will happen to her. I would like you to please replace our car problems.
