    Noticed the oil leaking first time around 4000 miles. Had the crankshaft seal replaced. Oil continued to leak. Can in to dealer for repair again. Seemed to take care of the problem. After oil change at around 18000 miles, oil is dripping again! Will be back to the dealer service department again this week.
