My 08' had this happen at about 9K in Jan 09'.. FYI - I had changed to Mobil 1 at about 2,500 mi, which I'm told may have hastened the leak. The speculation on this board at the time,was that it was the rear seal. However, the selling dealer did the dye and found it to be the pan gasket. Mechanic said that when the gasket was replaced, he visually checked the rear seal and it was dry. Someone posted or posted a bulletin, that the silicone used to seal the gasket was defective. Only took 2 days to fix, though car was in the shop over the weekend.
