1 Seats problem of the 2004 BMW 645

Failure Date: 08/03/2018

Passenger seat oc3 occupancy mat not working-it shows a fault code- I took it to birmingham BMW and was told I have to get a new BMW battery and battery cable. They charged me $ 120 to diagnose this problem but did nothing to fix the oc3 mat that is faulting. I have checked on line and this does nothing.

2 Seats problem of the 2005 BMW 645

Failure Date: 02/04/2016

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.

3 Seats problem of the 2005 BMW 645

Failure Date: 02/19/2013

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.
