“Engine wiring harness degrading, this issue has effected engine performance resulting in loss of power to car. This incident nearly cost me and my family their life. Due to the engine wiring harness degrading my vehicle suddenly lost all power and died (electrically) on the freeway. This issue is serious and needs to be looked into.”
NHTSA complaint #10168621, filed 2006-09, 89,000 miles“My mechanic told me that the wiring harness under the hood is rotting away. I have A/C problems with the wires and have had loss of power at the most inconvenient times. I'm starting to have different electrical problems due to this wiring harness and am very nervous of a possible fire as my granddaughter is usually in the car. If this is a problem other mercedes owners are experiencing, I feel it should be addressed by mercedes.”
