I was the driver and I stopped at a traffic light. I leaned over toward the passenger seat and the driver’s seat belt came loose from the fixed attachment point at the driver door side of the seat. The seat belt tensioner was recently replaced at the local BMW dealer. There was no warning or other indication that the seat belt anchor point was not secure. I am taking the vehicle back to the dealer for repair on Monday, June 20. Whether this is a manufacturing, assembly or repair issue is unknown. However, there was no advance warning and the seat belt suddenly was rendered useless, which is an unacceptable safety risk in the case of an accident, regardless of whether it is a manufacturing issue or the result of a negligent repair.

SEAT BELTS DO NOT RETRACT WHEN REMOVED. THEY MUST BE MANUALLY PUSHED INTO THE SEAT BACK. IF I FORGET, OR LOAN MY CAR TO SOMEONE THERE IS A DANGER OF THE SEAT BELT AND/OR SEAT BELT CLIP BEING STUCK IN THE DOOR CAUSING DAMAGE THAT MAY NOT BE NOTICEABLE UNTIL THE SEAT BELT FAILS IN AN ACCIDENT. I WAS TOLD BY THE DEALER THAT THIS IS NORMAL FOR THIS CAR.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your
pre-purchase inspection list. Back to the
