The seat bag sensor is continuously on. There is no one in the seat. This started at about 65k, the car now has 106k...is this dangerous to a passenger? Of course, this seems to activate the seatbelt light also...

What 2007 BMW 3 Series owners say
Most recent owner complaints, unedited.
I was going between 30 and 35 MPH through city streets at roughly 3am on my way back from my commute which is roughly 60 miles. I noticed it started to smell like burning plastic and immediately after smoke was visible coming from hood vents, I parked the car as soon as I could and popped the hood and the heat cover for the hood was on fire along with most other components in the engine bay. My friend immediately called 911 for assistance as I ran and tried to warn neighbors , within 7 minutes the car was completely chard. No maitnance lights were on and nothing seemed to be a problem. The two recalls I never received both would explan this incedent the federal safety agency campaign number: 17v683000 the federal safety agency campaign number: 17v676000

Despite repeated phone calls to bmw customer service, and stopping at the local dealership, no action has been taken by bmw for a recall regarding a spontaneous fire that can occur with my vehicle due to an electrical issue, even when the car is garaged and not in use. Customer service repeatedly tells me they don't have the parts to fix the issue. I learned about this problem a year and a half ago from the news. I have never received a recall letter from bmw, although I verified with them they have my VIN number and my car is part of the recall. I hesitate to even drive my car and have serious concerns about a spontaneous fire sparked by an electrical issue. It seems unacceptable as a consumer no action has been taken to remedy what could be a very serious issue (my house burning down for one). I am getting nowhere when I contact bmw.
Water leaks in my car on driver side front and back seat carpet is soak and smell. Not the first when going to get a car wash leaks occur. This is my second bmw I had a 2004 325l same problem with leakage. Also, no doubt rust have occur in this vehicle with on going leaks.
Replaced blower motor twice 4 months 1st one made noise and stop blowing air out vents now second one is making loud rattling noise. Constant tail light bulb issues display tail light malfunction.
Passenger airbag restraint failure - bmw's, in particular 3 series and e90 models, have a known and common failure where the seat based electrical mat fails in the passenger seats. This is not related to wear and tear as the seats often go unused but simply fail after a certain period of time. The error causes the passenger side airbag to default to always on, which can cause injury or death to children or small passengers in that seat. The cost to repair this is usually $200 for parts and $400 for labor which means many drivers simply don't fix it creating a vulnerability. The issue has been recurring with bmws for several generations and across model types and should be addressed by the manufacturer as its a poorly made part and set up. There are numerous documented cases on bmw forums and a partial recall for some models was implemented. A full recall is needed on all cars affected, including 2007 3 series models. The issue does not appear fixed until the f model 3 series came out.

For over a year now the airbag light on the dashboard has been going on and off. Originally, it was only turning on when I had a passenger in the front seat. Now it turns on with or without a person so I'm starting to think that the drivers side is malfunctioning too. In additional the seatbelt light is turning on too now. This is very frustrating. I talked to the dealership and they indicated that it is the airbag and seat sensors that have malfunctioned. Each to fix is over $500. They also indicated that this is a common problem for owners and to wait for a supposably recall letter. However, that was a year ago and I now have the airbag and seatbelt light going off. I've also come across many bmw forums (owners) talking about their frustration with these same issues. It's surprising that the dealerships acknowledge the issue but yet nothing is being resolved. There has to be a remedy for this annoyance and lack of acknowledgement by bmw. If anything there has to be some repercussions on bmw's part since the consumers are having to deal with these problem for what seems to be years now.
