'11 I had, had sunroof issues. Make sure you open and close yours on a regular basis or later on, you will have issues. Would've been $2500 to fix if it hadn't been covered under warrantee.
Third brake light leaked on mine. It was replaced under warrantee. Truck had a mildew smell after that.
I jumped the truck. A lot. The frame held up fine, but boy, could I tell a difference when I drove my '14 Raptor. The steering and chassis feels wayyyy tighter.
I had an engine tap issue with my '11. It's covered on Ford's TSB for that particular year.
I had the transmission shifting into gear hard on occasion. A few times a month. Nothing alarming, but it's an issue pretty widely known in this community.
Don't let anyone tell you that you won't have issues. Because you will. But I ramped up to a '14 because all of these issues have been corrected (save the sunroof binding, as I haven't heard anything about that). If you plan on jumping the truck on a regular basis (like me) I would suggest you look into the products available to strengthen the frame just so that everything stays nice and tight over the long run.
Good luck!
