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. …

Transmission & drivetrain
Purchased a 2007 ML350 approximately 2 weeks ago. Pulled into a driveway during a house hunting trip, placed the car in park with the gear change button on the right side of the steering wheel, opened the door, exited the auto, walked up the stairs to the house and knocked on the door. It was at this point I heard my wife and 2 children (who were still in the car) shouting at me. I turned to see the car moving forward. The car had been placed in park (the p was noted prior to my leaving the auto) and now the transmission had popped itself through n - neutral into d-drive and was rolling forward. I ran to the car and attempted to place my foot on the brake and place the car back into p-park, the car caught my leg and I was dragged with the car another 15 feet, until I was able to get the gear into p-park. I was unable to stop the car before it rolled into the closed garage door. …
