Larry, do a search on the problem and u should be able to fine a place to get just the seal. Used to have to replace the pump too, but have read that there are kits out there for just the seal. Saveslike $800 !!!! This a pretty common problem and there is lot of info here on it.
Welcome aboard.

as for the warranty, I have heard that it is covered and that it is not, kinda depends on the dealer.
