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.

The airbag light is on our BMW and my 16 years daughter is driving this car. I cannot believe that BMW did not issue a recall. According to Repair Pal: "What are the symptoms of a bad Air Bag Occupant Sensor? Failing occupant sensors can show one of two symptoms. They may stay on at all times, causing the passenger airbags to stay active even when a passenger is not present. Also, they may not operate at all, which prevents the airbags from activating when a passenger is seated in that seating position. Also, for most systems, the airbag or SRS warning light will illuminate on the instrument cluster, prompting the driver to service the system.

For some time we had to keep the driver side seat heater no higher than "1". At level 2 & 3 it burned you or felt like you were being stuck with something. On the date in question, I drove about 2 miles, went into a store, came back out, started the car, turned the heater on again (level 2 for about 2 seconds then back to level 1. I smelled a strong burning odor, then a smell almost like cigar smoke. Then immediately turned off the heater. The smell subsided within 3-4 minutes. However, it left a black burn mark on the leather seat about the size of a pencil eraser. Obviously, continued use will cause a full out fire rather than just burning the leather.
Approximately 1 year ago I purchased for my daughter a 2004 used BMW X3 2.5i. The car has run fine so far but in the evening of the 26th of January 2014 something very dangerous happened with the front driver seat heating system. She was driving and she notice a smell of burnt material inside the car, and looked down to see that the seat heater had burned through the left bottom side and had singed her pants. She of course was very scared and all most went out of the road for this! There is burnt a hole in the front driver seat and for the moment I pulled the fuses of the seat heating system (fuses was still OK and did not shut the system off!!). I have been calling BMW north America for more than a month, they sent me to a BMW local dealer where they inspect and made picture of the seat. BMW n.a. …

Driver's side seat burned through the seat and burned the jacket when the seat heater was turned on while my wife was driving. This is the second time it happened in this car. First time it happened while the car was under warranty, and the dealership (silver spring BMW of md) replaced the seat under warranty. In this case got lucky it did not catch fire or cause any injury to us. This situation easily could have ended up in a car fire. I was stunned to hear how lithely BMW na approach towards my concern when I called to lodge a complaint. At highway speed this could have been a fatal situation due to distraction this burn created worst car on fire.
