i have read all the forums and there are many complaints on this same safety issue and why hasn't a recall been issued? Passenger restraint system light stay on !

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 get in a auto collision it would be devastating. i mean this should 100% be a recall because of this is a wide spread problem that puts many many people at risk. i haven’t been to the dealer with it yet, but i can self diagnose because countless people have been reporting on forums and online the same issue with the same error on the dash. my car hasn’t been in an accident yet so i haven’t had it inspected by insurance companies or police. this problem first appeared today and my heart dropped.

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.

The Passenger Restraint System Malfunction warning light comes on randomly. Also the passenger side seat belt light comes on even if I put my wallet or something very light on the seat. I previously replaced the driver side seat sensor because the restraint system error was coming on. It seems odd that this critical component would fail in both seats by year six.

The occupant sensor in the driver seat has failed, triggering an airbag warning. This car is only 6 years old, and the cost of the part/labor to repair it is $2500.

I parked my car and there were not any lights on the showing. When I returned to my car about an hour later 2 lights were shown (1) 4 wheel drive and (2) Passenger restraint system. I am concerned about the passenger restraint system because until I can get this repaired, no one can use the passenger seat because of this safety issue.

The car is reporting that there is a passenger restraint system malfunction. When there is a passenger in the front seat, the airbag is disable.

Car randomly shows “Passenger restraint system malfunction”. I have read multiple complaints from other BMW owners about this issue that is not covered under BMW warranty.

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 is producing a warning light for "Passenger restraint system malfunction". This is a safety hazard and it is not covered by warranty. I believe this should be investigated and a recall should be mandated as many people have this issue. The cost to fix is over $2,500 and BMW should bear the cost of this safety issue.

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.

It appears that the dealer has disabled my passenger side air bag system. The car is available for inspection. The safety of any front passenger is at risk as the system has been disabled by the dealer after a 'vehicle check' that occurred during routine maintenance. The problem (airbag system disabled) has been confirmed by the same BMW dealer that performed the service. The vehicle has not had additional inspections. Prior to this problem, an alert/message would indicate the passenger would need to buckle up. Never was a passenger in the seat, I would move the groceries, backpack, water bottle, etc to the floor and message would dismiss itself. This message to buckle up has been appearing since the car was purchased as a certified BMW from a BMW dealer. Recently, I took my car into the BMW dealer that I typically go for scheduled, routine maintenance. The maintenance consisted of an oil change, oil filter change, air filter change, and vehicle check. When I started the car after picking it up, a chime sounded and a warning message was displayed that says "Passenger restraint system malfunction: Contact BMW Carefully drive to the closest service center. Passenger restraint system is limited. Increased risk of injury in case of a collision. Continue wearing safety belt." Additionally, a red air bad light is displayed on the dash board instrument cluster. Every time the car is started the chime sounds and these message is displayed. Dealer is requesting 2,000-2,500 to replace a part - meanwhile system was dealer disabled. Please note this issue has occurred in the past with BMW SRS systems, and a recall resolved the issue.

My passenger restraint system randomly faults. Problem with passenger seat mat. Many BMW owners have reported the issue. Should be recalled by BMW.

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.

I recently took my vehicle in for a service due to "passenger system restraint" error code. Upon dealer inspection it would cost upwards of 4,000$ to fix this issue. I called my warranty company and they do not warranty any repairs that have to do with restraint systems. This seems to be a widespread issue from what I have read. This can really cause a major issue if the seatbelt for the passenger side does not work upon a collision. This has to be putting people in a serious situation and should be investigated. Thanks for your time.

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 part went bad. This is the diagnostic message given: CHECK CONTROL MESSAGE PRESENT FOR PASSENGER RESTRAINT MALFUNCTION. PERFORMED VEHICLE TEST, FAULTS PRESENT REGARDING PASSENGER FRONT SEAT OCCUPANCY DETECTION. PERFORMED TEST PLAN AND INDCATED PASSENGER SEAT OCCUPANCY DETECTION IS FAULTY. RECOMMEND REPLACING PASSENGER SEAT OCCUPANCY DETECTION. According to the dealer, if this if not fixed the airbag and/or seatbelt won't perform in the event of an accident. This appears to be a very common issue for BMW and similar to a 2017 BMW Technical Service Bulletin MC-10146769-9999. There was no warning of this issue prior to receiving the error message. There has been no opportunity for moisture to compromise the sensor (via window, sunroof or drinks spilled). Nor has any cellphone been stored on the passenger seat as I've read of some reasons provided to other Owners with the same error message. This seems to be an ongoing issue with this part for some time and it would seem to be an important issue for BMW to resolve in their design for the safety of the user.

BMW has had known issues with its passenger seat safety sensors failing. These are expensive repairs exceeding $2,000+ and happen frequently with the 2018 - 2020 BMW 5 Series. My 2018 BMW 530e has had this sensor fail with regular usage. There hasn't been an abnormal exposure to moisture (I live in Utah, a very dry climate) and so the vulnerability of this technology and the cost associated with it's upkeep and it's necessity for basic safety, means BMW should own up to ensuring that this has better and more reliable craftsmanship.

NHTSA ODI 11537627

There is a sensor that has malfunctioned under the passenger seat. This passenger restraint sensor is meant to detect a person in the seat so the airbag can deploy. The problem is that I’m Oder to fix this send the cost is over $2,000. It’s not concerned by BMW although it’s part of their safety design.

Passenger restraint warning light continues to illuminate intermittently after services were performed to remedy. Dealer diagnosis showed the seat module had moisture. Dried out. Worked ok for a few months then reoccurred. Next mechanic diagnosed faulty CIS seat box. Replaced the module. Worked ok for a few months then reoccurred.
