My 2019 3.5 had the cam phaser rattle. $2700 repair with new timing chains. Ford paid $900. I paid the rest. That was with 80k miles. Other than that, very solid. Ran great and rode great as well. Around 18.5 avg mpg. Just rattled like crazy on start up. They redesigned the phasers, so if you go that route, make sure it has the new ones.
