Have had the battery replaced once. Battery has gone dead a couple of times. Get Ford messages sometime about remote being shut down. Never have got the message before battery dead in the morning. I carry a small jump start unit and have used it after overnight. 30,000 miles 2020 ST. Never had a new car do this before..
Anything with a dealer is a PITA the dealer I went to checked battery using the guy that checks the cars in and checks batteries routinely, Funny thing was when battery failed his test it was not good enough to replaced battery under warranty and had to be taken to shop for further testing and then they replaced the battery. If they had just tested battery routinely during service check in they would have told me is was bad if no warranty was involved with no further testing.
Actually my question was why did the remote still start the car after notification of shutdown. Found out today that it did indeed stop remote starting using Ford Pass but not using the remote (key).
When the battery went bad in November the car did nothing as to warning of shutting down. Just died overnight and could not even unlock doors electrically.
