Surges forward or backwards on its own. While backing it out of garage, it surged backwards so fast the brakes would not hold. Hit tractor parked in driveway before getting it stopped. Broke rear bumper cover. I have older vehicles (1974 chevy) (1990 chevy pickup) with absolutely no wiring problems.
Tl* the contact owns a 1994 mercedes-benz e320. While removing the rear driver side wheel, the vehicle's factory equipped jack failed. As a result, the vehicle fell on the contact. The contact sustained injuries to the collar bone that required medical attention.
Car was not starting brought to mercedes dealer replaced a sensor and the mechanic and advisor showed me the wire harness told me I should change it it is brittle and I will have future problems I only have 60,000 miles on this vechicle
I smell gasoline inside my 1994 e320 when I'm driving, just started smelling it on 3/20/15. Never before this date.
After replacing the ovp, $100, the car started fine and ended up being drivable but the owner noticed a very significant loss of power. It appears that there is misfire, in at least one of the cylinders leading from the ecu to the distributor.
Under normal driving condition engine started revving up to about 3500 rpm as if I pressed the accelerator pedal. Freaky experience but luckily the road wasn't too busy.
The mechanic advised that the wiring harness be replaced since it was deteriorating and could cause a fire. The manufacturer was made aware of the failure who did not offer any assistance. The vehicle was not repaired. The failure and the current mileage was 150,508.
