What 2004 BMW 530i owners say
Air bags all 49 →
While driving my car, with my wife as a passenger, I've noticed that the "passenger airbag off" light is still on (even though there is a passenger in the seat). I went to the stevens creek BMW dealership to diagnose the issue and they said that the reason the passenger airbag light is on is because the sensor is not sensing a passenger due to cable corrosion. That seems odd, given I keep my car in the garage and it never had any water damage. Also, I believe that it is a poor engineering on BMW's side, since in case of corroded cable or faulty sensor the default behavior should be to always keep the airbag "on". It is better be safe than sorry and (in case of accident) deploying an airbag when there is no passenger is better than not deploying an airbag when there is a passenger... This is a case of "potentially saving someone's life" vs "potentially saving a few dollars"...
Dt: the consumer's vehicle was involved in a crash with 2004 BMW 325i. Upon impact, both air bags did not deploy. The impact was the passenger side front door. The passenger side window shattered and fell into pieces. The car was taken to the dealership for repairs. The consumer has not yet reported the air bag failure to the manufacturer. There was one injury. A police report and pictures were taken. The consumer has the pictures. The insurance company has been notified. The speed was 25 MPH. Ms. Packard: the summary report created by the vehicle safety hot line does not clearly identify your vehicle. Please review the information on the vehicle owner's questionnaire and verify that your vehicle is a 2004 BMW 530i. Also, please provide a copy of the police report and photographs.

The heated seats start fires and BMW refuses to acknowledge that my car should've been a part of the NHTSA Recall 04V-575. The dealership denies any issue with the car despite knowing about the hole it burned in my seat.
