Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Hot spot in the back of the driver's seat from the seat heater. The failure was the heating element burned a nickel-sized hole through the leather seat, through my winter coat, and singed my pants. This happened while I was driving but stopped at a light. I was able to pull over once I noticed the smoke rising from the coat after smelling something very bad. I didn't feel the heat due to the winter coat. The dealership is replacing the entire seat as the heating element and seat are one component.”

“As I was driving my 2005 Bmw 645 ci yesterday, I noticed a strong burn smell in my car. I thought it was outside until I experienced the same odor today when I turned on my seat warmer. After some investigation, I've discovered there is small hole on my leather seat. Apparently, the seat warmer burnt through the leather seat causing the smell. This have got to be a defect, how can Bmw engineer a product that could potentially catch on fire. 02/20/2013 ....
