Yes it is price/construction decisions and yes I fell short in my research missing the lack of memory seats, didn’t even occur to me but I should have caught that. I had to look at gas Kona’s because EV isn’t available at the local dealership. Once again that wouldn’t have been a deal breaker, I would have still bought the car, it was just interesting that memory seat is a bank buster. My Sonata PHEV has memory seats. Also the mechanical passenger seat is a North American thing, in Europe the Kona has electric passenger seats. I don’t know if the driver seats remembers anything though. Apparently Europeans have more disposable cash.
I’ve probably lost 15% of my hearing while driving the Kona EV these past couple of weeks with all the Bells chiming and Whistles blowing. When I buy a car I buy it as if I were going to drive it for 10 years because . . . Well I keep my cars for 10 years. Past 30 years I’ve been driving Acura, Legend, CL, TL (why would you drop the name Legend?, It’s a Ford Mustang not a MLX) We traded my wife’s 2010 RDX in for the Kona. I always buy the top trim line. 2010 was a year before blind spot detection came in. Now the car practically drives its self. I was blown away with all the 2019 Sonata PHEV Limited had on it. Kona EV Ultimate has even more (except for the seats) So having to rough it for the drive train isn’t true. Hyundai’s price/construction decisions should be left to the consumer which it is with the various trim levels offered for each model. It is a “quirk” that the Kona doesn’t offer electric passenger seats or memory seats in North America.
That said, If I had “money” I would have bought a top of the line Tesla. My intro to EV was a ride in my brother-in-laws friends Model S. I’d never felt Gs accelerating in a car before. Living in the desert a battery doesn’t last very long so I was leery of Hybrid or EV cars. Hyundai’s lifetime battery warranty is what pushed me over the line. In my 30 year marriage with Acura the only thing any of my cars went in for other that routine maintenance was the Takata airbags in both my TL and my wife’s RDX. Acura gave me a rental for 3 months (waiting for parts, would have given us 2 but I thought 1 was enough) which turned out to be a Sonata. For a rental it was a nice car.
I love my 2019 Sonata PHEV, the 28 mile range covers about 80% of my driving. I had to start working on my wife to go to the Kona. She had range anxiety. The RDX never left Phoenix, I doubt she has driven more that 90 miles at a time and that would be rare so 258 miles should be more than enough. It didn’t help that right out of the box we had to drive 300 miles to get it home. Topped it off at the Ca/Az border and got home with 32 miles to spare

It hasn’t taken long for her to fall in love with the car. It’s was charged after the initial trip, (8 hrs) today it’s at 48% so range isn’t an issue.
So except for the seats (in North America) it’s a heck of a car with more bells and whistles than you can ask for. I can’t imagine what there will be in the next 10 years. For now I guess I’ll just have to rough it. Alexa, please make me another margarita, no salt. I hate roughing it.
