I was driving my leased, 2003 Volkswagen Jetta, (equipped with cold weather package), on a very busy road in late afternoon on a cold autumn day just outside of boston. I turned my driver side seat warmer on the highest level, (5) and in about 5 minutes I felt a sharp pain on the backside of my left thigh and thought something had stung me at first. I repositioned myself in the seat, and could smell something burning. I looked down and saw dark brown smoke pouring from the seat and realized the seat was actually burning me. I immediately turned the seat warmer off, pulled over, (again in very busy traffic in watertown, ma), and got out of the car to find a dark brown, dime-sized burn mark in the seat!!! The heat actually went through the seat and burned a small brown mark into my blue jeans and subsequently, left a small welt on the backside of my thigh. …
In December of 04 the drivers seat caught on fire in my 2003 Volkswagen Jetta glx. I had the heated seat on when I noticed the seat was getting extremly hot and started smoking. I was on a busy four lane road and unable to pull over at the time. Once I did pull over I jumped out of the car to survey the damage. I had managed to burn the tips of my fingers and my "rear end". Vw replaced the seat under warranty after I waited almost a month for the seat to come in. Needless to say I was very irate at the dealership and was told by the service advisor that "I was over reacting". I called vwoa and reported the problem but they too did not seem concerned. I did my own little research and was able to come up with a couple hundred other cases of seats catching on fire in volkswagens. …
Sunday evening I left my house to run out to the local convenient store when the driver seat of my 2003 vw Jetta caught on fire. The heat settings run as high as five, my setting at the time was on two. I felt heat generating beneath my rear-end and when I lifted my leg to look below me, I saw and felt the flames beneath me. Trying to put the fire out, which by the time I'd got pulled over to the side of road had burned through my jacket and pants, I'd burnt my hand in an attempt to squoosh the fire between the seat and the cushioning. Not a pleasant experience. The seats are 'velour'. This is my third and last Jetta. My previous Jetta had the heated 'leather' seats package and I'd never had this experience. The dealer was kind enough to replace the heating components, cushioning and seat cover. …
I use my heated seats almost daily in the winter months. I used it this morning for about 20 minutes as I drove from home to the gym, then another 10 minutes as I drove from the gym to the store. When I got into my car after the store, it was still on the same setting (5), I had driven about 50 yards in the parking lot, when I felt a sharp pain in my left upper leg/butt. I moved slightly, then began to smell smoke. I felt around with my hand and felt the "hot" wire and the hole in my seat. It took me a moment to realize what it was, and then I immediately turned down the heated seat to off, thereby preventing further damage and pain. Luckily there was limited damage to my clothing and I was not seriously injured, but had I been driving on the highway, or not been able to figure out what was causing the pain so quickly, there could have been more severe consequences including injury.
We purchased a brand new 2003 vw Jetta in June of 2003. I have had no problems with the vehicle until yesterday, 11/28/04. We could smell something "hot" and burning. The drivers seat caught on fire from the heated seats, there is a hole in the seat and my boyfriend burnt his hand. Within minutes of that happening, the passenger side door window just fell down. I've never seen anything like this before. Somehow, the window is no longer in it's track. I have been doing some research online and finding many more instances with the windows falling and the seats catching on fire? What is the deal? This is very unsafe. I have my appointment tomorrow with our local vw dealer in erie pa to see what they will do to correct this. I want both seats looked at....I do not feel safe in my car any longer!!!
On March 24,I turned my seat warmer to level 2,all of a sudden I felt a burning sensation. I kept driving thinking maybe I was bit by a bug or something. About a minute later,I saw and smelled alot of smoke. I had to pull over and when I looked down at my seat,it was dark and rainy so I turned on my dome light,there was a dime size hole in my seat. I had turned off the seat warmer when I realized what had happened. I got home and there was a burn on the back of my left leg. We contacted the dealership and they fixed our car in about 10 days. There had been an electrical short and they replalced the seat and fixed the electrical.
This morning, 4/5/05, I turned on my heated leather seats in my 2003 Jetta gls and in a matter of about a minute, I felt something extremely hot on my leg. I immediately lifted myself up from the seat but it was too late. I looked down and there was a hole burnt into my leather seat, smoke coming from the seat and a burn in my pants...not to mention my skin. What I find disturbing is not that it happened but the fact that I took my car in last Thursday and was not told about the problem even though a recall had already been issued. If vw had been proactive, I would not have had this injury and property damage.

I currently own a 2003 volkwagen Jetta and have been driving it for 2 years. I live in michigan and as a result use the seat warmers regularly during the cold winter months. I have never had a problem or any complaints until yesterday. I drove about 1 mile and had the seat warmer on 3, which isn't the highest setting, and my seat caught fire. I had to pull over to the side of the road, get out, and proceed to stomp out the small ember burning. I know have a dime to nickel size hole in my driver side seat.
