“For a few months now, my car has been throwing a passenger restraint system malfunction error. It happens sporadically and only stays up for between 1 and 5 minutes at a time. It will happen whether the car is moving or not, and even sometimes as soon as I turn the car on. I have been submitting the telecommunications since it started. I tried to have it fixed by thompson Bmw, only to be told, like the other user who has this problem on here, that they think moisture is the culprit. …”
NHTSA complaint #11110925, filed 2018-07, 6,500 miles“Constantly pops up a message for passenger restraint system malfunction. I had an accident where I swerved off the road into a ditch at about 60 mph. I the driver was not hurt and the passenger wouldn’t have been hurt either if it was for the passenger seat belt not locking correctly at first and then repeatedly locking and unlocking the entire time hurting his chest.”
NHTSA complaint #11641549, filed 2025-02“i was just driving my bmw and a airbag light and a malfunction error popped up on my dashboard, that read that the Passenger restraint system has malfunctioned. and i was doing some research on what was wrong with my car, and all the forums are indicating that this is a very common issue on these cars due to a bad seat occupancy sensor mat. to fix this you either still have to have an extended warranty if you don’t have one you have to pay upwards of 3,000$ to get this part replaced at a dealer. …”
NHTSA complaint #11648020, filed 2025-03“When i have a passenger in the car I will intermittantly get the warning Passenger restraint system malfunction which will turn off the air bag to the passenger side when driving even when there is a passenger in the car. From forums it sounds like there is a pressure pad in the seat that is a very common malfunction for BMW. This seems like a pretty critical part to ensure the airbags are operational when a passenger is in the car, and feel it should not be as common a problem as it seems to be.”
NHTSA complaint #11591952, filed 2024-06“My car has around 74k miles on it. I had the following service request warning present itself this last week, 'Passenger restraint system malfunction:' on my drive into work in the morning. At first I dismissed the message and closed it to see if it would clear itself. It did not clear. It came back up a couple of minutes later. This time I left it alone. It proceeded to close itself and reopen every minute or so for about 10-15 minutes. Then it turned off and didn't come back on until I started my car later in the day and again the following morning. …”
