I was rear-ended during a traffic slowdown in freeway, while driving my 2014 BMW 328i sedan. Due to the collision, my vehicle's safety system got invoked, which made the gear automatically go into neutral and the flashers turned on. However, my seatbelt (driver, left-front seat) unbuckled automatically. This caused me to hit the steering wheel during the accident. I didn't suffer major injury as I had slowed down to less than 20 mph, while the vehicle hit me in the rear (which had also slowed, though didn't stop on time/didn't have the distance, and hence the collision). After the collision, when I checked, the socket from which the seatbelt is pulled had got loose, and the belt had a double fold in the buckle, and so it got stuck. It didn't rollback to its place.
I was driving to target and from a stop I was 75% through the turn when a car ran the stop sign and hit my car straight on . The impact was supposed to deploy the airbags but was not deployed due to a malfunction, I was injured in this accident from my neck down my back . My injury claim is still open with the party at fault.
Passenger Restraint system malfunction for the front passenger seat. This may not trigger the airbag for a passenger sitting in the front if a collision occurs and can seriously injure someone. This problem appears to be very common with BMW models within this timeframe. All over car forums and youtube videos, some videos with over 100k views per video. I am not sure how BMW has not recalled this safety issue as it seems to linger throughout many of their models for many years. As soon as the malfuction occured\, the warning sign and lamp lights did flash on.
Received display notification of "Passenter-restraint system: Fault in airbag, belt tensioner or belt fore limiter. Continue wearing safety belt. Consult nearest service center." Upon taking to service center, they mentioned there was no recall for airbag. Peace of mind placed at risk.
Passenger restraint system malfunction. My vehicle as well as thousands of others have the chronic and unsafe issue of the passenger occupancy sensor malfunctioning. In order to remove warning on dash it's either a $2,000 repair, or a $40 bypass which basically places the seat as constantly occupied, sticking the passenger airbag in the 'on' position. Vehicle is available for inspection. With this malfunction, any person that sits in the passenger front seat is at risk of injury or death in the event of a collision. Malfunction has been confirmed by both a dealer and an independent service center. Vehicle was inspected by the dealer, but no police or insurance company. Vehicle was purchased with the malfunction and the warning lights have been on for several years. …
Vehicle at approximately 36,000 miles started exhibiting an intermittent warning for passenger restraint system malfunction. BMW of ontario, ca diagnosed the issue as a faulty seat occupancy sensor, but declined warranty coverage due to vehicle age and exclusion from 3rd party warranty. This appears to be a fairly widespread issue based on: 1) many of the online owner forums cover this problem. 2) the problem is widespread enough to support several manufacturers making and selling bypass\emulator devices to circumvent the failed sensor. A critical safety device for controlling airbag deployment should not be failing so early or frequently.
Passenger restraint system malfunction alert when car is turned on. Air bag and passenger seatbelt warning lights are on. Passenger seat belt light will never turn off even with no passengers in the car. Air bags for passenger are off when there is a passenger in the car causing a safety concern. BMW wants $1000 to diagnose what the issue is for the airbag light only but not to fix it or check the seat belt light. Already paid them $100 just to tell me exactly what the message said on the car screen. Seeing the same issue all over the internet with flaws in the passenger restraint system for this model and similar models but no fix. Found an extended warranty but does not list the E92 model, all other models are listed.
I had my passenger in the car driving 30mm and then I got a "restraint system warning " illuminating the seatbelt light and seatbelt with airbag light. This is a safety concern as it is still on without a passenger. This affects the passenger airbag so in the case of fatality this would fall on BMW NA for neglecting to fix this issue. The car was fine before and this came out of no where
