I have the original 2013 Titanium FFE. I have about 55k miles Recently the battery stopped charging up to 21-ish and now tops out at 13mi estimate. Chargepoint says it has drawn 5.14 kWh on a typical charge.
The Ford dealership near me (Santa Monica Ford) is not at all supportive as JSAMP suggests. I'm surprised there isn't some sort of aftermarket battery option after 10 years.
I heard that Ford is spinning off their EVs into a new company.
