Car had unexpected accelleraton during a routine left hand turn in an intersection with a stop light; pressing on the brake did not stop the forward accelleration, crashed into a wall, occurred downtown, early evening, no other vehicles or pedestrians hit; driver injured. Driver not under the influence of drugs or alcohol. Brakes serviced recently.
Was driving all gages went crazy started to back fire and died on the highway so I had a friend pull off the highway back to the shop the shop said the wiring haress was degraded and it cost 2,700 dollar to fix the sad thing is this car only has 30,000 mile's.
My 1996 mercedes C220 has a defective engine wiring harness. The check engine light came on and I took it to my mechanic. He told me that this was due to the type of insulation that mercedes used for the wiring and the engine harness needs to be replaced ASAP. Mercedes used a bio-degradable wire cover that with high temps cracks and falls off. This has caused the engine to run rough, stall and loose power and is not safe to drive in traffic. This should have been taken care of with a recall by mercedes. Mercedes has been of no help except for me to pay to have it repaired.
Engine wiring harness, and the transmission wiring harness, and the ignition coil harness, degraded to the point there are inches and inches of bare wires touching and shorting which causes the engine to quit. All three separate harness which reside with other harness which have not degraded. The engine quit on the freeway in rush hour traffic and nearly caused several accidents at 65 miles per hour. Repair shop want $3500 to change out the three harness with no assurance that the problem will not come back.
