Passenger seatbelt/airbag warning as follows: "pass. Restraint system - fault on passenger restraint system affecting airbag, belt tensioner or belt-force limiter. Continue to wear the safety belt." Note: The vehicle is currently with a mechanic who has confirmed this is the "passenger seat mat sensor." I called BMW of North America today to report the problem and check for recalls. I was informed I should go to a BMW dealership to get a "formal diagnosis from the dealer" and to "confirm if the issue could've been included in prior recall." Note: I searched the NHTSA website for my year, make and model vehicle and found this exact same issue was under "investigation" from Jan. 4, 2008 to Dec. 31, 2008. The investigation subject is "BMW airbag light illumination". the summary states that it was for BMW models from 2004 to 2006 and states the 2006 models were recalled for the X3 series and 3-series with sport seats. It further states "BMW will extend the warranty coverage of the passenger seat air bag occupant detection mat to 10-year/unlimited mileage on approximately 120,000 remaining MY04-06 subject vehicles built through 11/30/05." Therefore, I believe my vehicle should be included based on the later statement. My incident first occurred on thanksgiving day, Nov. 24, 2016. The warning light has not turned off since then. The vehicle is currently with the mechanic for a large unrelated to this sensor mat issue. I expect I will have the vehicle back in 1-2 weeks, at which time I will take it to a dealer to further investigate BMW's responsibility for this safety issue. Specifically, the issue occurred while my mom was trying to put on her seatbelt while sitting in the front passenger seat on thanksgiving day. The warning has continued since then whether or not someone is sitting there.

The vehicle was taken to an independent mechanic where it was diagnosed that the front passenger seat occupant detection mat failed and needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 124,000.

The passenger seat mat sensor is defective and cannot tell when a passenger is seated, therefore, not allowing a passenger air bag to deploy. The SRS air bag warning light appears. The passenger seat has not been tampered with, rarely been sat in, and the defect cannot be attributed to any error on my part.
