Pretty different situation for me but last month I dropped my truck off at the dealer for a slow coolant leak. When I was changing my oil last I noticed some coolant leaking down over the starter, truck was leaving small spots on the driveway overnight and my coolant level was going down very slowly. Turned out to be the passenger side turbo coolant lines were leaking slowly. Dealer replaced both lines under warranty.
