Positive battery cable is corroded, including the wires connected to the battery terminal. Corrosion was a large mound when we opened hood to add washer fluid. Tried to remove corrosion and discovered the entire connection to battery terminal has disintegrated. Rigged it up with $3 part from autozone. Dealer states they've never had any such problems. Dealership has the only people that have been under the hood of my car. I am there every 5000 miles. . . . Like clockwork. Can't believe they didn't see signs of this on last visit. They want $3100 to replace the main wiring harness! what would have happened if I didn't catch this? it would have shorted out and possibly caught fire.
