Failure Date: 12/20/2017

About 3 weeks ago we noticed in the front passenger seat "a mark" that looks like a burnt - we thought that it was just a mark or somebody put a hot bottle o cup on the seat - but this morning we turn the heating in both seat to warm up a little bit then smell and smoke start to come out the burnt mark. We turned it off both sides and open the window - now our conclusion is the heating element caused that burn in the seat.

3 Electrical System problem

Failure Date: 01/01/2013

BMW recalled 2004 BMW 525i and others for the seat mat sensor. I had called them (2012-13) and they told me that my vehicle (based on VIN) wasnt part of the recall. I informed them that my vehicle's mat sensor was also defective and should be replaced by them. They, BMW USA told me that mine was not defective. I still cant understand if the rest are defective, how come mine is considered not defective when its inoperative and same problem as thousands of other 2004 525i.

4 Electrical System problem

Failure Date: 10/16/2010

The contact would like to use his submitted email as the actual complaint. Our 2004 BMW 530i had the driver's heated seat catch fire. I am not getting much help from BMW on this matter. To me, this is one helluva of an easy way to cause a major accident. Only because of my partner's quick thinking and turning off the heater was she able to stop the fire. It was hot enough that it melted the foam (toxic I am sure) in the seat. Something like this happening while you are going down the road is right up there with Toyota and their acceleration problems. Either way a major accident can happen. Not to mention that a person could be severely burned. While the car is out of warranty this seat has never been abused. The driver of the car weighs in at about 120 pounds. From checking the internet there seems to be a quite a number of such instances. Thank you scott the failure mileage was 60,000.
