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. and me personally i don’t have the money to just spend on car repair of that amount and im sure alot of the other people with this same problem are in the same boat as me. this could be very dangerous because it puts all my passengers at risk if i were to...
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.
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.
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. After taking it into the BMW dealer, the warning light was able to be replicated by the dealer and they've told me it is the seat mat (occupancy sensor) that was faulty. No outside influence appears to be at fault for the failure. Just that...
The seat occupancy sensor malfunctioned. The technician said the computer showed it had moisture that caused the problem. I had the sensor replaced and the repair shop siad there was no sign of moisture contamination. I took pictures of the seat cushion allow with the imbedded sensor and there is no sign of moisture. I feel the sensor was defective and BMW should have been responsible for the replacement but they use the excuse that moisture caused the problem.
Passenger seat indicator light keeps going off intermittently. Dealer says its a seat pad issue. We identified it in 2018 but dealer was not able to fix it and it continually keeps happening and didn't do anything because dealer did not fix it at that time. Now dealer is re-diagonising it saying it is a different diagnostic code but we have seen the same issue since we got the car. After reasearching this, there was a recall in 2017 with similar issues. It is related to the sensor and if not properly working, the airbags may not deploy when needed. This appears to be a safety feature of the car so should be recalled like previous. Please investigate.
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. I HAVE NEVER HAD ANY RAIN OR ANY OTHER MOISTURE GET INTO THE CAR, AND EVEN IF IT DID, THIS WOULD BE A HUGE SAFETY RISK. THOMPSON REFUSED TO FIX IT AND SAID I WOULD HAVE TO COME OUT OF POCKET FOR THE SEAT, WHICH IS RIDICULOUS. I HAVE BEEN IN CONTACT WITH THE SERVICE MANAGER, AND THE...
