On 1/17/25, I was on my commute to my office when I noted a very strong and unpleasant odor. Thinking it was from a truck in front of me, I passed the truck, cracked my passenger window and continued the short distance to my office. After work, when I returned to my car, I noted a hole burned through my driver's side leather seat. I didn't make the connection to the odor from that morning until I arrived home and did some online research. It turns out that my front seat warmer had malfunctioned, burning all the way through the leather. This problem is well documented online in various forums in my year, make and model. In some cases I read about, driver's clothing burned. In one case I found, a child was burned. This is also a well documented problem that occurred in earlier models of Mercedes, resulting in a lawsuit and a recall. My car is currently at the dealer for repair of the faulty seat warmer, replacement of the burned foam cushion, and replacement of the leather seat cover. This could have been so much worse had I been earlier in my commute, or on a highway where I could not have pulled over. It seems like this problem should prompt a recall.

On January 01, 2025, I started my wife's car after adding coolant. I just want to warm it up since we did not use it in a couple of days. I activated the heated seat on the driver side where I was seated and was just looking at the dashboard. I felt something on back right side and thought that there was an insect bite. When I turned and look, I discovered a dime size red small flame and smoke on the seat and realized that it is possibly and part of the heated seat heating element that burned through the seat material and burned my sweater a little bit. I turned off the heated seat immediately and shut off the car and made sure the burning stop or was out. I was thankful that this happen while I was just warming out the car and stationary and that it did not happen while my wife was driving the car. This could have produced a dangerous situation, a bigger fire while driving and could have cause an accident. I called the Mercedes Benz service department which was possibly closed but I got a call back the following day and they said that there is no open recall on this vehicle on anything. I ask what is my option and the answer was to get it checked at the service dept. and that it would cost $351 just to find out what was wrong with it. I schedule service for Jan 14, 2025 at 3:30 pm. No police or insurance inspection was done. There has been no warning lamp or message to warn me of the problem. Jan 01, 2025 is the first time it happened. I told my wife not to use the heated seat and put a note on the car to inform anyone that will be in the car even though it is just my wife and I that drives the car.
