I have a FFE 2017 and they fixed a lot of that.
1) Range is 110mi (winter: 80, summer: 130)
2) Acceleration is improved (I smoked a Porche Boxster between 2 very long lights).
3) Sync3 is better, and they support Android Auto/ Apple Carplay.
4) DC Fast charging support = 30m recharge ( we have one at my office) to about 80% from near-zero.
Some things are unchanged / still suck: traction due to it not being 4wd - is the same. Battery position is the same (really unfortunate since it kneecaps the benefit of having a hatchback. The radio always comes on if I disconnect CarPlay - I wish I could disable it from every getting AM/FM as I find it mostly ads and useless.
That said, I still really enjoy the car. It's more fun than my old Prius, still fits 5 (3 kids in back) and I never visit a gas station. Of course, I'm on the list for a Model 3.
