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.
Remedy: Dealers will rework the front passenger seat sensor mat so that external force application to the seat does not cause a crack to the mat. The recall began on November 6, 2008.

Daughter turned on vehicle, turned on heated drivers seat, as she was driving on a city street, began to smell something burning, pulled car over & got out, left vehicle running, continued to smell burning and began to see smoke. Saw that a burn hole was forming in the left side, bottom of leather seat. Turned seat heater off and smell and smoke diminished. Upon inspection of he clothing it was also discovered that the seat began to but a hole in her outer jacket. It did not burn through her clothing and she was not injured (thankfully).

My wife has a 2005 BMW X3 with an airbag warning indicator light illuminated on the dash. The problem/symptom is that there is a little red light in the instrument cluster that looks like an airbag is deployed along with a yellow light above your head that says "passenger airbag off". So in the event of an accident the passenger airbag would not deploy. There is a sensor under the passenger seat that is basically there so that if a person that does not weigh a certain amount, like a child for example, is sitting there the bag will not deploy because it has been known to cause problems for smaller individuals. However, since the sensor becomes defective, the system defaults to airbag off mode and therefore you never have an airbag regardless of who is in the passenger seat. …
I own a 2005 BMW X3, purchased new 5-5-05. On 12-19-11, while at the dealer for service, tech advised that during short test, he noted faulted pass seat mat sensor. Dealer replaced pass seat mat sensor and enabled. At no time were prior recalls on this issue mentioned nor was I provided documentation concerning any extended warranty. On 5-14-15 (note the date) the SRS warning light on the dash came on and remained lit while the pass seat air bag light would not go off. Took car to dealer 5-19-15. They confirmed the same seat mat sensor they replaced on 12-19-11 was again faulty. However, this time they would not replace as it was beyond the heretofore "extended warranty" by 14 days. Took vehicle to local shop who replaced seat mat sensor. Faulty seat mat sensor retained for possible testing. This is a significant safety issue that BMW is ignoring. …

Was driving with seat heater on. The seat felt very hot on my legs at it smelled like something was burning. I immediately turned off the seat heater. I pulled into a parking lot and exited the car. I noticed a burn mark on the drivers side seat. There is a matching burn mark on the wool coat I was wearing. The coat is what prevented me from being injured. I have pictures of the damage if you need it.
