My Differential leaks at the pinion seal, why is that?
The pinion seal leak is a quality issue from the supplier that makes the differential, Getrag. The leak is solved by properly installing a new seal according to supplied procedure. It is not a safety issue. We have seen service that improperly installed the seal, creating a second leak after the initial repair. I do not know the details of the exact issue, but I do know it is NOT an issue with fluid seal material compatibility.

I cannot relay the exact warranty rates, as I do not have the exact information, but we are aware of the issue and have been working to resolve it. This issue also has been seen on the cars that share the differential (Cadillac CTS/STS/SRX).
