Update:
We sent the car to the dealer, since I was working under the assumption this would be covered under the 8 year warranty.
Dealer told us the high voltage cable to the AC compressor need to be replaced, and it would not be covered under the warranty.
After going around and around with the dealer and Ford about this being a unique component to the electric drive system, the dealer told us they were not covering it because of rodent damage. Dealer suggested to go through our insurance, which is what we are doing, with $1000 deductible. From the picture, I would have just fixed it myself if I had known where the problem was and how to get to it.
So how do we keep the rodents from doing more damage?
