same thing happened to my X5, cabin completely filled with smoke and burned left butt. The truck is 7 months out of warranty but is under the certified bmw extended warranty. The seat is not covered, dealership won't do anything for me, so now i'm fighting with bmw canada. I found out bmw had recalls on this problem for other models in the past, but they are still putting the same product out there. The new seat cover is 1100 and 300 to install, crazy. My first BMW and i'm thinking my last.
I can't believe they know about this problem and keep making it the same
