Have a 2010 myself. I have had 3-4 leaks over the years and (in my case) every single one was due to a failed oring. Latest was on the cooler thing in the driver side bumper area. That one took me a minute to find as it was not obvious and the last place I checked. In the crank area I would take a good look at the egr cooler and even the orings on both ends. Many people have had issues with the cooler leaking and I believe they have updated that part once or twice. Flashlight, mirror, and a borescope camera would help if you have access. Good luck.
