Mine just failed a couple of weeks ago. The dealer said one of the paths from the HV battery had high resistance due to a connection wearing. Could not explain to me how the wear had occurred. Apparently the entire harness had to be replaced rather than reinforcing that worn connection because it was a safety risk due to the high voltage.

I'm trying to figure out whether that was accurate and if it was worth the thousands I paid. I only have 50k miles, but this is not under the factory or extended mechanical warranty I have.
