ESP Light, Uncontrollable acceleration..very serious problem
I own a 2002 ML320, and have been dealing with a serious problem with this vehicle for over a year. While using cruise control, the car will accelerate rapidly on its own and the only way to stop the car is to put the car in neutral (the brake will not work and the cruise control will not disengage).
I have taken the car to the dealership each time this has happened. They replace the ESP sensor each time, and the car returns to normal. After the fourth time this happened, they replaced the ESP sensor and then proceeded to tell me they found the problem. Thousands of dollars later, the throttle body was replaced, as well as the throttle cable.
After a week of having the car back, the problem has come back. ESP light is on and the uncontrollable acceleration happened again. Keep in mind, each time the ESP light has come on, the brake lights do not come on, and you have to use a pen or pencil to get the transmission out of park and into drive or reverse.
Have any of you heard of the uncontrollable acceleration problem in Mercedes Benz vehicles? The car is at the dealership now, and having just invested 3k and still having the same mechanical problem, I'm starting to lose faith in my Mercedes dealership.
Any suggestions or insight?
Thanks-

No brake lights??, No cruise cut off with brake?? ESP failure?? All that would encourage me to have them look at the brake light switch, could be intermittentely defective. As for the throttle cable, the only cable goes from the accelerator to the box on the firewall where the throttle signal is converted to wire and transmitted to the throttle body electronically. That can't be a factor

I purchased the car new at Ed Potter, and haven't had any negative experiences with the service I receive at Germain (aside from this annoying situation). However, I just dropped $1700.00 less then two weeks ago and the problem is not fixed. This is a pretty dangerous problem to have, so I hope they are able to identify the problem.

dude take it back
make them refund you all the labor it cost of the $1700, apply that refund to new labor to fix your issues....only pay for the cost of parts in this since they haven't a clue what they're doing.
Locally here, i had an issue with the air conditioning at autobanh motors in California, they said it was this, i paid for it...still had the issue, said it was that, fixed it, still had the issue...i ended up paying for parts only and said they're flippin wasting my time.
