Brought my Prius in because ABS warning light was on. They told me repair bill was "$8000 USD, probably more" due to rodent damage and entire engine harness had to be replaced. They even suggested taking out comprehensive insurance and claiming retrospectively. We took it to another garage who said just one or two wires were chewed and repaired for $160.

Bought the car at this garage and had a good experience with regular service until this incident.
