I didn't experience any leaking but my 2011 with 90,000 miles is in the shop now. Blown turbo. It started with a high pitch whine and then went completely out that night on the way home from work. Fortunately it is covered under the drive train warranty so no cost, but seems odd it has gone out already. I have had the same issues as most: squealing tensioner/pulley, the growling when starting, hesitation when accelerating etc etc etc. The car looks great and is great inside, I just always wonder how long it will last mechanically.
