I have read that the ecoboost engines with the direct injection can be the issue here. The 3.5 twin turbos in the F-150 were known to do the same thing. I think the fuel is being sprayed right on top of the piston and then blows past the rings. I am not sure there is much they can do about it. The good news is that you probably won't have any issues with the car in 3 years, so you can just turn it back in and start over.
