Selected complaints filed with NHTSA by 2006 BMW X3 owners, lightly cleaned up (personal details are redacted by NHTSA).
I turned on my heated seat and within about a minute and a half I smelled a burning smell. Pulled over as I started to feel a burn on my leg because the seat heater has burnt through the leather in my car. This is a known problem at BMW and they have not issued a recall for this.
As I drove home from a long flight home after the holidays, the engine caught fire due to a frozen crank case ventilation system which caused oil to spray out in the engine compartment. I pulled over when I noticed smoke in the passenger compartment and smoke coming out of the hood. I was able to blow out the fire. Temperatures were 5 degrees f that night. The dealer stated there was a "more robust crank case ventilation system" that they would install at my cost. After the week long repair, the dealer brought my car to the front and turned on the seat heaters. I drove about 5 miles before noting a pinching/painful sensation on my left upper thigh. I pulled over to find a burn mark on the leather seat and a burn on my left upper thigh. It appears to be due to a short in the seat heater.
Driver seat heater caught on fire this morning dealership said no recall yet million msg boards clearly show faulty issue I have documented over 30 separate cases already since 2009!

Was driving down my BMW X3 down the road with my seat warmers on and the inside of my car started to smell like something was burning I figured something was wrong with my seat warmer so I turned it off a little ways down the road I pulled over to check and make sure my seat was okay and noticed a small burn on the bottom left on the back of my seat and I checked my sweater and there was a burn mark on it too
My heated driver side seat shorted out and burned a hole in the leather seat, and luckily being in the auto industry and having a knowledge of seat construction I immediately turned the seat off. There are numerous reports of this issue on various BMW forums., including fires! I think this is a serious safety defect that BMW should be held accountable to fix and repair.
I was driving and noticed a burning smell. I had my seat heater on and noticed a very, very hot spot on the bottom part of the seat on the left side. I hurried and shut the seat heater off, but noticed burn marks on the leather. The seat would have definitely caught on fire if I hadn't shut off the seat heater.
While using driver side seat heater, elements overheated burning through the leather seat and burning the left side/hip of the driver. Car was in motion and almost caused an accident. Pulled over and turned off the heater immediately and haven't used it since.
We were driving in cold weather and activated the seat warmers on the driver and front passenger sides when we detected an odor of something burning and smoking. We stopped and got out of our SUV and discovered a burnt hole/spot on the driver's seat, lower left seat back bolster. On taking it our BMW dealer for repair, we were told that the seat warmer was defective and that is what caused the burnt hole/spot on the seat back, I.e., "failed component 3". Further we were told that our SUV was two months out of warranty, and that the cost of repair would cost $2,900. We have searched the internet and discovered similar malfunctions on bmws equipped with seat warmers. Further, we had to replace the seat warmer system on the front passenger side approximately two years ago because it too became inoperative. …
Head protection system was deactivated the air bag warning lamp illuminated and the air bag "on-off" lamp illuminated as well. After purchase there was no illumination of these lights and then about 2 years later while driving in the city at about 45 MPH, both lamps illuminated when my son and I were heading to the store. I called BMW and they told me then that it was probably due to a cracked seat mat sensor and a recall on those sensors was being extended for 2006 X3 models. I called our local BMW today to schedule a repair of the seat and have the car parked in the garage since August 2017 due to a possible vehicle safety issue with a system failure of airbag deployment. My son has been unable to use the car for college which is 4 hours away. Now I would like to understand why this vehicle is not considered under the extended warranty notices of 08V384000 or 17V605000.
Within two minutes of driving, on a city street, the car with the heated seats on, I smelled a burning smell and thought it was coming from another car. But the smell got stronger and it didn't smell like a car-related smell. Eventually, the smell got so strong and pungent and I suddenly had a sharp pain on my left hip and I realized it the heated seat was burning me. The pain was so acute I had to lift myself off of the seat, which was dangerous and could've resulted in an accident, and I immediately pulled over and turned off the heated seats. Once I turned the heated seat off the pain and smell dissipated. I got out of the car and there was a clear burn hole both on the seat and on my pants. The smell of burnt fabric lasted in the car for several days and for the rest of the day I experienced sharp pains on my left hip as if it was getting burned again.
