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.
I turned on my seat heaters to the lowest setting (1out of 3) just as I left work. After about 20 seconds as I drove down the road, I felt a sharp burning through my wool jacket in my left thigh/butt area. I turned it off immediately. When I got home and looked at the seat, it had left a burn area in the leather. After looking at different websites and forums online, it seems to be a very common problem with this model. However, based on owner's comments, the dealers aren't taking responsibility.

My 2004 BMW X3 has heated seats which burned a hole through the seat and almost burned a hole through my pants. I was driving and almost wrecked from the pain. After I pulled over and jumped out I saw a burn in the seat that looked like a cigarette burn. BMW wants to make $700 to replace the heater and another $700 to replace the leather. Took it to charleston, sc dealership.
Felt a burning under my leg and smelled burning plastic. Parked the car and my scarf was melted to the seat and smoke was coming from it. Pulled on my scarf to get it off and noticed a hole burnt in the seat from the heated seat element. Parts of the seat were stuck to my scarf and pants. Made sure the seat stopped smoking and wont use the heated seats anymore.
Driver's seat heating unit overheats when on high setting, to the point of burning skin through the seat and clothing. Lower left lumbar and seat bottom appear to be impacted. Per service shop, the seat heater grid is broken, causing 40 degree higher temperatures than normal in the left leg area. Ongoing issue, not a single occurrence.
Driver side seat warmer was set on the medium setting, smelled something burning and then started to feel pain in my leg, because the heated seats had melted the leather and burned my pants and my leg.
As I was driving on the freeway with the driver's side heated seat on the low setting, I felt a sudden burning sensation on my back of my upper left thigh and shifted slightly, putting my hand under the area to see what was the matter. The rear area of the left side seat bolster had gotten so hot I had to turn off the seat heater immediately. I decided not to turn it on again until another time in late March when I again turned on the seat heater. The same sudden feeling of "overheating" was immediately felt in the same area, I turned off the seat heater, and I haven't used it since then. When my car was in for service for another issue, I mentioned it to my service advisor and asked whether he knew of other similar incidents or whether there was a BMW recall for the issue. He said no to both questions.
