Nov 2025 Injury

The seatbelt/passenger seat fails to recognize a passenger is occupying the seat and turns off the airbag. This issue has been reported many times to BMW and on vehicle forums. This is an expensive fix ($2800) that should be issued a recall by the manufacture and not passed onto the owner of the car.

The passenger seat is a mess. There are two issues that repeatedly happen on this car. One - there is false passenger seatbelt warning and two their is a passenger restraint system malfunction message. I took this to the BMW dealership and they said it requires a sensor mat replacement that costs over $2000. I looked it up online and found many people have had the exact same issue with this car.
