Bought a 2016 f150 5.0 with 2 weeks its been back at the dealership the so called extended warranty they sold me doesnt cover a single thing supposedly and they wanted 900.00 just to swap a few solenoids well long story short i have swapped them the ones i took out were brand new looking and seemed to work fine so now im at the phasers being the culprit to all the issues well again not coverd under premium warranty not sure if anything is covered to be honest so canceling that trash first chance i get im about ready to take the truck back and just get my money back cause this had been nothing but bs
