    If the wires weren't factory, then they CAN fail in short order. Make the dealership guarantee their work, i.e. if the new wires don't fix the problem, you don't pay. If they balk at this, then they are guessing and take your car to a shop who will stand by their Diagnosis AND repair. I always do at my shop.
