I was on the freeway, I was using my cruise control (luckily just after heavy traffic hours) just like any other day. A car slowed in front of me, so I went to apply my brakes. As soon as I hit the brake pedal the brakes not only did not disengage the cruise control but the brakes got stiff and would not work no matter how hard I pressed them. At the same time the accelerator was floored and the car was trying to go what seems like 130-140 MPH. It took all my strength to try and keep it at an appropriate speed. Luckily my passenger told me to stay calm and tried to help me disengage the cruise control. I had to maneuver the car to the slowest lane and shift it into neutral. That was the only option I had besides crashing into the car in front of me. I am extremely shaken from this event, I have anxiety/panic attacks whenever I drive any vehicle now. I am currently looking for a physician to help me work out some kind of treatment/therapy.

I have been the owner of a 2000 mercedes ml320 for about 6 years. The car was purchased from the dealer with approx. 30,000 miles. Today it has approx 73,000 miles. Since owning it, I have had several problems which were all out of warranty and which I feel were unwarranted and were not seriously attended to by mb or the dealer: this complaint form was very difficult to complete according to the fields provided. The equipment information included is not correct and was included just to get to the form. I felt that the problems with the car should be reported specifically the esp light and the air bag problems at about 51,000 miles, the airbag became inoperative. I was told that it would cost about $2000 to repair and correct. Dealer offered a small adjustment. I chose not to make the investment. At about 65,000 miles, I began having very loud noises that seemed to come from the crankshaft and appeared to be a brake problem. Dealer did try to determine what it was, but couldn't isolate the problem unless "he had to take the whole car apart" there was a related problem because the esp light would come on intermittently that the dealer advised could not be isolated unless I did the work on the brake and the crankshaft:" at about 72,000 miles, the car developed oil leaks from the motor. Est. Cost of repair was $2000. We are watching and waiting. In may, I was advised that there is a recall notice on the cruise control of the car. No word on that issue since. Because of the cruise control notice I received, I was prompted to write you about these other issues and became further concerned about the esp light and the faulty air bag the care has had., car is driven an average of 150 miles a week in mostly city driving. Car is serviced but not by the dealer because of the high cost and relative dissatisfaction from the service provided. Updated 07/27/11
