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

brown fluid drops on garage floor. Dealer said they must R& R PTU and reseal for $820.70 Hoping I can find it done cheaper somewhere else.

We are now on our 4th seal and it's now has gone bad. Dealer is saying we need a new PTU ... for a seal issue?
