I have a 2017 GT. There is a typewriter noise coming from the wheel well on a cool start at low rpm's. Ford says it is found in some the 5.0 liter motors in 2011-2019 vehicles .
Ford also states it is not detrimental to engine function or durability. Anyone else have this issue. Sorry if I'm beating a dead horse, I tried to do a search, and could not find anything related.
