Air suspension failure: Initial failure - front end suspension failed - lowered completely where tires would appear to contact wheel well. Dealer 'fixed' problem second failure - left front air suspension lowered, the remaining three did not lower itself. The car drives at an odd angle with left front end pointing to the ground. Again the tire appears to make contact with the wheel well. Ride is rough.

I had been noticing that the front of my car had been dropping down and rising up spontaneously. When the front of the truck dropped down the car began to violently bounce up and down to the point that I nearly hit my head on the roof. The car was barely drivable until it rose up again. On 2/18/2011 I pulled my truck out of the garage and heard an explosion and the right front side dropped down and would not rise up again. I took it to my mechanic and he said that the air struts were gone. The right side had exploded. He contacted many of his prior employee's who work at Mercedes Benz dealerships and they told him they had been having problems with this part. They even had the parts in stock due to the demand. This is definitely a safety issue and if I or my wife were on the highway traveling at 70 mph and this occurred, that could have been a fatal rollover. I also have a problem with my powersteering locking up when I turn the wheel.. my mechanic also said that this has been an issue and a recurrent problem part. I bought this vehicle for safety and it turns out this is the farthest from it. I also had to have my driver's seat replaced by Mercedes as it burnt a hole through the leather nearly catching my wife's coat on fire. Please investigate.

I own a 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 10mph on a 50 mph zone with 10 cars in back of me! the shop told me it was the two 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.
