Default eco-boost cylinder scoring

Has anyone else had this happen with their F150? I had this happen just before Christmas and it was completely rebuilt under warrantee. Now, I think it may be happening again. Dealer said something got into the cylinder and caused the original scoring back in December after owning for just under four months. This is the third F150 and the first that has given me a problem. I'm afraid it's happening again because of the dirtiness of my tailpipe drippings and the stains on my driveway. My neighbor claims to have heard of a known problem with this engine because the plugs are too low in the cylinder and there are some that have the piston impacting the plus, thus breaking off a piece of the plug.

Has anyone heard of this happening?
