I have a problem with the A/C of my 2006 Volkswagen Passat 2.0. The technician tells me that basically all the components of my A/C system is damaged and need to be replaced. After I search the internet, a lot of people have been having the same problems since 2007 and it's for models from 2001 to 2007 (as far as I can find now). Please investigate this issue because I believe it's a design problem instead of a wear and tear problem. Hopefully we as consumers can rely on you to help us fight for justice.

The heated drivers seat in my 2004 vw Passat caught on fire and burned through my wife's jeans. This occurred after driving only 1/4 mile. She felt something on her leg and when she looked down there was smoke coming out of the seat. She stopped and got the fire out, but it had burned her(left a red markon her leg),her jeans and put a hole in the seat. The local vw dealer was contacted and made aware of the problem and they are replacing the defective parts on the driver seat. However, when questioned about the passenger seat being defective, it was explained that they have only had a problem with the driver seat. I would think that they used the same materials in both seats and that the reason there has not been a problem with the passenger seat is due to the possibility that it is not used as much. The potential danger if this is not corrected could be significant. …

Started car, heated seat setting was on 1 (lowest setting). One of the heaters must of shorted, I felt something on the side of my thigh right away but didn't see anything. Within one minute, noticed burning smell, smoking. Looked down, saw smoke and small flame. Immediately turned off seat heater, jumped out of car. Seat had burn hole size of silver dollar and was hot in that area only. Since it was christmas, I couldn't take it back to the dealership until the next day. When I got into car later, even though seat heater was off, I got a small shock when I started car. Car is still under warranty and dealership has been very helpful and was quite concerned, but can't replace parts right away (parts had to be back ordered from Germany). They disconnected the heaters for me because I prefer driving my car around instead of the rental they offered. …
