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.
