My Ford Mach e had a potential issue that was fixed with an over the air update. It involved the battery terminals.
I have noticed that it charges more quietly now; it must throttle back the charge to the point where the cooling fan isn’t needed as much.
BTW, I charge mine after work, but while still awake. With my short commute it’s up to 90% in an hour or so.
Because I’m partial to Mustangs (I own a GT)...I’ll refrain from making negative comments about the E version. LOL.
However, we also own a F150, and I gotta say...the dashboard monitor/system sucks. Just did the Sync 3.3 to the 3.4 upgrade especially for the updated NAV function. It’s horrible. You’d think...you spend $60 grand on a truck and you’d get a decent onboard computer system. Wrong. I am now using my Android’s Google maps function to navigate.
Don’t even get me started on the Ford Pass app.
The point I’m making, I guess, is that I just don’t think I’d trust Ford with that specialized a system. (I will say though, that we test drove an Escape Hybrid years ago. I was very impressed. Wound up with a Prius instead.)
Takes an hour to charge it to 90%? Imagine then if you had to do it while on the road - wait an hour before being able to continue your trip.
