“On and off system notification of "Passenger Restraint System Malfunction" with and without a passenger in the seat. Also, the Airbag off/disabled light on the instrument cluster illuminated. Can't seem to declare if it is an electrical shortage, seatbelt buckle related or passenger pressure sensor sensor in the seat. Find this to be a major safety concern should there be an accident, and unsure whether the airbags will deploy or not. BMW should investigate this concern.”Owner report · Electrical System · Apr 2026

“1) Passenger restraint system malfunction. According to information on the web and several BMW forums, this is a common problem on these vehicles and it is a serious and inherently unsafe issue that should necessitate a recall from the manufacturer. The root cause is typically a malfunction of the passenger seat pad that is utilized by the passenger restraint system. BMW service repair cost is $2,700-$3,000. This is really outrageous given that it's part of the safety restraint system and many BMW 5 series (and likely others) have this problem.”Owner report · Air Bags · Jan 2025
“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.”Owner report · Air Bags · Jun 2024
“The vehicle throws a "passenger restraint system malfunction" every 5 minutes while driving. Based on discussions on bmw forums, this is a common issue among several models of BMW. The issue seems to be caused by loose wires/sensors beneath a he passenger seat.”Owner report · Air Bags · Jan 2024
“245/35 R20 Dunlop Sport Maxx GT Found tires to be bulging out on sidewalls. Service center confirmed that both front tires were separating and are unsafe to drive on. Susceptible to blow outs. Rear tires have not been inspected as of yet.”Owner report · Tires · Dec 2023
“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.”Owner report · Seat Belts · Nov 2023
“Passenger seat restraint malfunction error code. Code will show fault when no one is in the passenger seat and if the person is light enough in weight, it will also pop up. The issue means that the air bag will not deploy when there is someone in the seat. A HUGE safety concern and online search shows that this is a very common problem with BMW's. BMW needs to issue a recall for this and fix the issue. Please note that the date the incident occurred below is an approximation and the code has been continuing since the first code came up.”Owner report · Air Bags · May 2023
“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.”Owner report · Seats · Mar 2023
