They don't sell the Kona EV in PA. I bought mine in Cumberland, MD -- about 2 hours away. I located a car rental place a few doors down from the dealer. Rented a car, drove to Cumberland, dropped it off and someone from the dealership picked me up at the rental place. Bought the car, drove it home.
The EV part of maintenance has actually been less of a problem than just a crappy experience period. Maybe it would've been a better experience if they were more used to the EV. Maybe not.
My local Hyundai dealer is sort of crappy. Lots of recalls, no loaners. Everything takes all day. They have never successfully fixed my brakes that squeaked from day one. They have never acknowledged the playing-card-in-spokes sounds.
Apparently one of the other dealerships (that Mattsburgh goes to) is better, but not nearly as convenient for me. He also found out that one of the (even further) dealerships is the designated one for battery replacements, so maybe they are more comfortable.
About a year into owning the car, a deer ran into the side of it. The collision center attached to my local dealership fixed it no problem (plus they also fix a lot of Leafs).
The reality is that Hyundai gives the dealerships service manuals to update software, change coolant, and even do collision repairs, regardless of whether they sell the car here.
