Front passenger seat caught fire and burnt a hole from bottom up, took to the mechanic and he said it was from the airbag sensor that caught it fire, I was getting hair done at6 pm in evening, came out I hour later and smelt fire, looked and there was hole in seat, turned on air and rolled down windows, waived a magazine over it and made sure it was out. Drove home about 10 minutes away and air bag light came on. Tried to call BMW they were closed, went to my mechanic next morning he told me it was faulty to call BMW, I called BMW plaza and they told me tough they wouldnt do anything. I hated the hole so went to autozone to get something to repair it which made it look worse...been looking on line for seats very expensive. My boss told me as well that should be directed to attorney general which I messaged from missouri and us attorney general. …
Passenger seat airbags are disabled due to restraint detection malfunction. A message appears upon turning on the vehicle which states that due to restraint system detection fault, passenger airbags and restraint system will be turned off. Problem started as an intermittent issue and developed into a continual one. Happened for the first time in April 2014 and has continued to worsen. Car is equipped with BMW OEM sport seats. This issue appears to be in line with recall from NHTSA campaign number 13v-564. However, BMW does not recognize my VIN as being a part of this recall.

I have a passenger restraint system malfunction problem. I went to BMW dealership last week. But they told me my car is not on campaign so I have to fix out of my pocket. However, as I found on the recall list like below vehicle make / model: model year(s): BMW / 3 series 2006 BMW / 5 series 2004-2006 BMW / x3 2004-2006 summary: BMW is recalling 200,000 my 2006 3 series sport seat, my 2004-2006 5 series standard and sport seat, and my 2004-2006 x3 passenger vehicles. Depending on the manner and frequency of the front passenger's entry and exit, small cracks have developed in the mat. If this occurs, the front passenger air bags, with the exception of the head protection system, will be deactivated and the air bag warning lamp as well as the passenger air bag "on-off" lamp will be illuminated. …
For the listed 2006 BMW e90 330i, the following error message was displayed in the idrive interface. "pass. Restraint system: fault in passenger-restraint system affecting airbag, belt tensioner or belt-force limiter. Restraint system malfunction!" the failure occurred with nothing occupying the passenger seat while travelling approximately 35 MPH. The seatbelt, airbag, and passenger airbag warning lights remain illuminated with and without a person occupying the passenger seat and cannot be cleared. BMW was contacted and stated the VIN did not qualify for a recall of NHTSA campaign id number 08V384000 (air bags: frontal). The vehicle has not been repaired. This defect causes a severe safety risk due to possible seatbelt and airbag system failures resulting in potential fatality. …
I have experienced a front passenger air bag warning light on my 2006 e90 330i BMW with sports seats. The warning comes on and goes off, as it pleases. I have contacted the local dealer and was referred to BMW of north America for further instructions. I contacted BMW or north America, presented my VIN number and have told them of the problem I have experienced. I was advised that my VIN number was not included in any recalls and I should also check www.NHTSA.dot.gov. I have searched for this warning information and have come across this recall with NHTSA campaign id number: 08V384000 (air bags:frontal ). My vehicle, model, year, and equipment appears to be in the recall and experiences the exact symptoms as indicated in the summary. …
My vehicle has an airbag/seatbelt light eliminated on the dash. BMW has diagnosed it as a failed passenger seat mat sensor. 2006 330i sports seats were recalled for this item in 2008. My vehicle which has sports seats was never called for the recall. The manufacturer has also extended warranty for 10 years on all 3 series models with out the sports seat option for this sensor, but for some reason they will not service my vehicle as warranty or recall work. I have talked to two separate dealerships and BMW directly. They said my only option would be to file a complaint and that the government would have to warrant a recall on this vehicle and combination of options. This does not make any sense! This is a safety concern, as of right now the vehicles airbag system on the passenger side will not function if in an accident.
This is in regards to NHTSA campaign number 08v-384. I called BMW about his recall and they stated my vehicle was not affected even though the problem I am having and multiple others are having is for the exact same issue, condition, and description as called out in campaign number 08v-384. I did more research and found that BMW May not have the affected vehicles loaded correctly in their system. For example they tell you that the sport seat is not covered (which I have), but if you read the letters from BMW to NHTSA, many sport seats are covered. I suspect the database BMW is using to tell if a car is covered or not May not be accurate compared to the vehicle categories listed in the NHTSA filings.
Passenger side airbags are deactivated. I am receiving through the idrive computer the following message "system restraint malfunction", also the passenger air bag light is always on the instruments cluster. I found out that there are several complaints, and an existing recall about this same issue but I was told at my BMW dealer that my VIN number was not included. I am having the same exact issue that others have complained about and it is a serious safety issue that BMW should address accordingly. Once again, even though my vehicle make, model and year follow the criteria of the existing recall, my VIN number was not included.
