My 2014 FFE is at 142,000 and I get about 10-13 miles per charge. I’ve had to replace the small battery once and soon a second time as I am getting the “shutting down to save battery” message as soon as I turn off the car.
what I find that seems to be working:
I try to always have some EV range when I start the car. Not always possible if I forgot to switch while driving.
I tap the EV button to save the remaining range at about 7-8 miles every time I’m driving.
I try to run the vehicle with least amount of energy draining mechanisms. It’s counterintuitive to has so many base things that are awesome but drain the EV and the battery like the seat warmers, phone chargers, and AC.
the last one I do not know if it matters but I am getting the oil changed more often than the oil indicator calls for.
I drive around 90 miles a day for work.
