2 complaints -1 I was driving w/out a coat on & turned the drivers seat heater on. Then I started feeling a sharp, stinging pain on my back and started smelling the burning of what turned out to be the seat. I almost had an accident trying to get what I thought was a stinging or biting insect off my back. Once I realized it was the seat heater, I turned the seat heater off, only to find I now have a hole in my seat. If Mercedes knows they have this problem, as I have come to read here, they should warn people not to use the heaters to avoid an accident and avoid having a hole in the seat or replace the seat and heater. #2 the front air suspension shock crashed on the front of my car. My car sat in the dealership for over a month waiting for Mercedes to reengineer the air shock. Finally, they told us to buy an aftermarket and they would install. Shortly thereafter rear of the car wouldn't level and they said it was the compressor so that was replaced. But still the rear was uneven so they replaced both rear shocks and still the car wouldn't level. Then they had the nerve to tell me it was the front aftermarket and they now needed to be replaced. And the dealer told me the car was a 2007 so what should I expect. I stopped going to the dealer and instead took it to a private shop. They replaced a sensor for a minimal charge and the car has been fine since.

Mercedes GL450 the front end started riding low after driving it and would then adjust itself, which was very noticeable not the minute amount is supposed to do just for aerodynamics. Then it started out low from a parking position and once on the road it would raise a little to where it was drivable that went on for two days I had an appointment to get it inspected and on the third day the front end just lowered itself and the whole car was very unstable jumped up and down because of tbe great difference between the front and back I was driving on a one lane road on a mountainous region which is where I live and had nowhere to pull over. I made it after driving at 30 mph on a 45 mph zone, front air suspension struts that were leaking and told me this car was notorious for this problem. I need you to please look into this O believe it is a hazardous dangerous problem with this vehicle!
