I need help! Had service done at a Ford Dealership. When I got it back it will not go into EV mode at 68mph speed. In Nov 2014 I had an issue where the car said it had the updated software but it would not go into EV mode on highway. Ford made a dealer reinstall the software and when he tried he found the existing software corrupt. Had to uninstall all software, reinstall original software and then install updated software. Since that time the car has been running great and getting between 39 and 42mpg, with EV mode operating 36 to 47% of the time.
now, the EV is operating between 2 and 4% of the time. MPG has drastically reduced. Anyone have any idea what a tech could have done to make such a dramatic change in my car? Any ideas about how I will even fix this problem?
