3 Front Seat Heater/cooler problem

Failure Date: 12/15/2015

1) car is having recurring issue with seat burning due to seat heater. Dealer corrected issue but issue persists. Not able to turn heater on. Dealer claims issue is fixed but when heat seater is turned on, burning smell and smoke fills car. Advised dealer that car is leaking water in since noticed water on the truck in the rear where the computers are. Once water is in, all sorts of electrical light issues happen with the car. 2) car is having transmission issue. Upon research, it seems Ml350 has this recurrent issue. Cannot understand why benz is not having this recall. Car stops moving in the middle of highway. Cannot get it to run. Have to turn the car off, push it aside and try multiple times for car to move. This is extremely dangerous with kids inside truck since that is the reason why I bought truck for over more than 35 k. Dealer claims its a transmission cover valve body but does not guarantee repairs. Dealer states even after this repair, the issue could persist and transmission needs to be replaced which could cost another 4000 usd in addition to 2000 to change plate. It is obvious Mercedes Benz has let us down and also has made it dangerous for us to drive their cars. Please investigate this issue. If you go online, everyone with this truck is having this issue and is shelling dollars out to mercedes dealers for fixes that are not guaranteed.

16 Front Seat Heater/cooler problem

Failure Date: 01/21/2008

While out of state on vacation, we activated both the driver side and the passenger side seat warmers in my car. After about two to three minutes of activating the seat warmers, we began to smell burning leather. All of a sudden we began to see smoke coming from the driver side of the vehicle. After seeing the smoke, we pulled over to the roadside to see where the smoke was coming from. Once we exited the vehicle we realized my husbands jacket and shirt had been burned by the malfunction in the driver side seat back warmers. After inspecting the seat back, we saw that the seat had a large burn area. We immediately turned off both seat warmers and the vehicle's engine. The burning finally stopped after tuning off both the seat warmers and the vehicle. This was the worst encounter that I ever had with a vehicle, and the vehicle happens to be a brand new mercedes-benz Ml350, 2007 model from downtown la motors. I had always dreamed of owning a mercedes-benz, but I never thought that I would have this kind of experience with such a prestigious vehicle. I thought that I had purchased my dream vehicle, but after this experience I realized that I was mistaken. This experience spoiled our trip, and traumatized my family and I. Not only did it spoil our trip, we were inconvenience and devastated by the damage to the vehicle and also to my husband who was almost burned by the incident. My vehicle is now in the process of being repaired by the dealership. Upon completion of the repairs, I will be hesitant to use the seat warmers in my vehicle again because the confidence and trust I once had in my vehicle has been diminished. I am afraid that it may happen again.
