On two occasions (once from a stop and once while moving at 30 mph) I have pressed the gas pedal to the floor to accelerate quickly and the car has malfunctioned. Both times the electronic stability control immediately became disabled, the ESC warning indicator lights came on, and the engine stopped responding to my pressing the gas pedal. I was able to maintain forward movement but I could not accelerate. I could press the pedal to the floor without the RPM gauge needle moving. There was a real danger of being hit from behind when this happened because I was slowing down unexpectedly. I pulled to the side of the road, turned off the car, and restarted if after about 6 seconds. Once I restarted everything returned to normal. I have never had a car in which I lose the ability to control speed by pressing the gas too hard. I am told it is some type of "safety" feature to protect the transmission ("limp home mode") but I find it to be very dangerous. I would rather destroy a transmission and have the car respond to my commands then have a computer decide to turn off the accelerator while I am driving and risk a rear end collision. I see some similar comments about this on the intranet for Mercedes.

I was coming out of the parking garage. I proceeded to the entrance to garage. The street was narrow for two cars to pass by. I made a right turn from the garage exit to the narrow street with 5 mph speed. There were two cars about 25 feet away already on that street. Those two cars were waiting to make a left or right turn on main street at the T junction. Suddenly my car accelerated to 45 mph approximately. I applied the brake but the brake did not even slow down the car. With the brake not working and the car accelerating very fast, the car became out of control. I was approaching the cars in front of me. In order to avoid hitting the cars in front of me, I steered my car to the left of these two cars. I went fast beyond these two cars and came on the main road. I noticed a car was coming close from the right side which would have hit my car. At the same time, I noticed that on the lane on left side there was no car in close vicinity. To protect other cars hitting my car, I steered my car to the left lane and drove my car over the curb. The car went over the curb and hit a street electric pole. The curb and the pole stopped the car. The middle section of the front of my car hit the pole. The impact of sudden stop destroyed the front middle part of the car and also shattered the glass windshield. The air bag did not deploy. Upon my insisting, Mercedes Benz checked the car for sudden acceleration and brake failure. They told us that nothing was malfunctioning in my car. I do not trust them: So I seek your help in this investigation for sudden acceleration and brake failure as they did not find the cause of car malfunctioning. I was taken to emergency for treatment in an ambulance. I missed several days from office. I am still physically hurting on neck/shoulders and continue to take prescription pain killers; but lucky to be living.
