“My wife was driving my kids to school, when smoked filled the cabin of the car. She panicked and called me and I told her to turn the car off and get out. My son noticed that his mother was smoldering. Please see the pictures attached. I contacted bmw and they are not willing to do anything. I look online and found the document attached and noticed that this is a very common problem. How many times does this need to happen before someone get hurts seriously. Please consider a manufacturer's recall so that these obviously defective warmers can be checked or replaced.”Owner report · Seats · Feb 2016

This car hardly gets driven.. Has never been in any accident.. Never driven in snow.. Only a handful of rain storms and that was because I got caught in one. It is in pristine condition!!
