    Had the seal replace less than a year ago. It's leaking again, and now the dealer says the seals are fine; but it needs a new PTU to the tune of $1,700.00. Frustrating that such a great car, has such crappy dealer service.

    Power Transfer Unit Leaked. It seems that either the leak or some other event caused the internal casing to burn up. now the unit has to be replaced at a cost of ~$1400
