Tl* the contact owns a 2005 BMW X3. While driving approximately 35 MPH, the contact noticed a burning odor inside the vehicle. The contact coasted the vehicle to the side of the road and noticed smoke coming from the front seat lumbar cushion of the driver's seat. There were no injuries. The vehicle was taken to taylor BMW (4180 washington rd, evans, ga 30809, [phone]) where it was diagnosed that the front driver's seat needed to be replaced. The vehicle was not repaired. The manufacturer was contacted and did not assist. The approximate failure mileage was 118,000.
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).
The heated seat was so intense it burned through the seat and burned my leg. I originally thought the area affected was a burn hole in the seat from a cigarette, afterwards I realized that the burn hole had been created by an heating element that was exposed in that area and burned through the leather and then my leg. We've been afraid to drive the car for other electrical issues. I contacted both the dealership and the manufacturer and no one has helped me to this date.
I left home and turned on the seat heater for the driver seat. In just a few seconds I felt discomfort in my left buttock. I repositioned thinking something was pinching me and then smelled something burning. I was able to pull off the roadway and get out of the car. I saw the seat bottom scorching and immediately turned off the seat heater. No further damage was noted, but now afraid to use either seat heater.
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.
The left side of the drivers side seat heater has overheated and burned through the leather and my pants. There appears to be similar complaints on this website and a NHTSA recall bulletin number 04V575000 for older 5 series vehicles. I think this investigation should be expanded since so many people have experienced this behavior.......updated 12/03/15
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. …
Seat warmer caught on fire! While parked in the driveway with the engine running, I turned on both manufacturer-installed front seat warmers (outside temp. 36 degrees farenheit) for my son and I. I felt a pinching on upper left thigh / buttock. Thought it was a bug. Shifted in the seat, and felt it again, more painful this time. Lifted myself from the seat a bit to look at the seat and see what was poking or pinching me, saw smoke coming out of a new hole on the left side of the seat. Looked through the hole, and saw flames and smelled burning. Immediately, turned off the seat warmer, got out of the vehicle, reached over and turned off the vehicle. The seat smoldered for another couple of minutes. Called my spouse to check if it was still smoldering, but it had stopped. Took the vehicle to the dealer to get it checked out.
The seat heater in my 2005 BMW X3 caught fire and melted a hole in the seat and burned my left butt cheek while I was driving. My left butt cheek was burned a little but I was otherwise uninjured. I read online that a ton of other people with the same/similar make and model car as me have had the same problem. The dealer said it would cost about $2000 to replace the entire seat. There is clearly a major flaw in the seat heater and it could pose a major safety issue should a fire occur and the driver is not able to leave the car right away. BMW should recall and/or pay for the replacement/repair of the seat.
My drivers seat burned a hole through the leather and singed my pants. Almost caught on fire and I almost lost control of my vehicle. The car filled with smoke and I now have a pea sized hole in my seat. The heating element apparently has shorted out inside the seat. I read there have been other occurrences of this on these vehicles on some of the websites but there is no recall out, but there should be. This is extremely dangerous. Occurred on 12/31/2009 on my bmx X3 2005. I called the dealer and they said the seat would need to be replaced at my cost of $1500.
