Anyone work on mustangs? I have a 2019 Mustang with all of 31k on it. Long story short . Back right passenger tire will not hold air. Had tire replaced over the holidays .fast forward to last night Pressure was fine, then suddenly drops to 19psi, then to 11. Can’t see a nail. but won’t rule that out . I am betting bad valve stem / Tpms unit that leaks. Any thoughts ? Ford dealership in sandy springs has a 7-10 backlog of work, know of a independent shop that works on this stuff?
