    I went in for an oil change today at the Mazda dealership and was told that I had a battery cable corrosion issue. My service rep told me the cable wires that attach to the battery are corroded and that I would need to replace them with a new wiring harness as soon as possible. Due to this problem, I also need a new battery. The estimated cost is $600. The service rep said at any time the cables could snap causing the car to completely stop. He also stated that Mazda had cheap parts for this cable area and that he had seen this problem occur quite often in these vehicles.

    I had same problem with my wiring harness. The technician said it was a common problem in Mazdas. Seems like there should be a manufacturers recall for this. Either the battery terminal has a faulty design or the harness, but the corrosion should not travel down the harness.

    Corrosion is going heading into the starter if not fixed soon but having problems finding replacement cables. I'm guessing that I will have to go to the Mazda dealer to get them.
