2003 Mercedes-Benz E320 Owner Comments

problem #4

Sep 022005

E320 6-cyl

  • Automatic transmission
  • miles


I was parking my vehicle (2003 Mercedes E 320) between 2 cars in a parking lot. The vehicle was already on the parking spot (after making a right turn to enter the spot... while the feet were on the break pedal) when there was a sudden un-intended acceleration that made the vehicle race off and hit the concrete wall about two feet in front of the vehicle. The vehicle sustained considerable damage to the front bumper, hood, head lights. The front doors were jammed causing the driver to use the passenger doors for exiting the vehicle. There was burning smell (but no smoke) in the car soon after the impact. The airbag did not deploy causing the driver hit the steering wheel. As a result the driver suffered severe neck, chest and abdominal pain. There was a recall on the braking system of this model in 2004. This as addressed by the dealer (rallye morors, roslyn, NY).

I purchased a Mercedes-Benz E320 in June 2003 and have continued to have an issue involving uncontrolled acceleration and speed "surges" since September 2003. The condition seems to be more prevalent when the vehicle is approaching low speeds or in a downhill plane the dealership has attempted to repair the vehicle during five (5) service appointments and has acknowledged they are aware of the uncontrolled power, or acceleration, fluctuations. They have attempted to repair the vehicle using M-B advice; without success. M-B representatives have acknowledged this condition exists as well; but, that it is not a "warrantable defect." This "surging" has further developed into "bucking" on several occcasions causing loss of control of the vehicle. This condition appears to be similar to other complaints filed with the NHTSA regarding the E320 where the torque converter lock up is described. I do believe it is a safety hazard due to the inability to control the power / speed fluctuations of the vehicle.

Vehicle lunges forward and slows unexpectedly. Upon acceleration will jerk back and forth as it is about to stall.

Throttle control failure causing exactly a 20 second delay before the car would actually accelerate after pressing the accelerator. This caused me to be in nearly 3 accidents, because the car did not move when I was in the middle of an intersection and pulling out of a parking spot, cars were coming, but I could not move forward, until after the 20 second acceleration delay. When I turned the car into parkplace Mercedes, the invoice showed that they had to replace my ignition system as well as the throttle control system.
