 2.7 ecoboost. My first oil change was done by the dealer, then my truck often smoked a lot. I had the same dealer make sure they put enough oil in it. They said the oil level was fine and the smoke was normal and gave some silly reason. Then only a couple thousand miles later my low oil pressure alarm went off. I called a different dealer and they asked me to wait. I took it to them anyway because the motor sounded awful. TSB 17-0007. Excessive oil consumption issue with 6 months worth of build dates effected. I got a new motor and they reinstalled the old turbos which I'm concerned about. My hood no longer lines up, and my steering is off. So back to the dealer it goes on Monday. Now I have a new $43,000 truck that I'm not happy with, and it's got a carfax that shows a motor replacement which devalues the truck significantly.  In addition, my doors rattle and shake when going over bumps. If you are thinking about buying one of these trucks it's a risk in my opinion. Ford refused to buy it back.
