One other note about my experience (similar to another poster), after the dealership verified that I'd limited charging to 80% pre-replacement, I kept and drove the car until it was time to take it in for the replacement appointment. I'm quite surprised by the number of posters whose cars seem to have been effectively confiscated while awaiting a replacement. There is no reason for that if you're limiting charge to 80%.
To the person getting annoyed by the negative comments, I'm another happy camper. Our Kona is one of the best cars I've ever had. I admit, though, I've supplemented with a Rav4 Prime (another fantastic ride!) so I could take longer trips without worrying about finding a rapid charger along the way. The Kona is great for any driving along the Wasatch front and, with planning, even longer (before we got the Prime it'd taken my wife and me to San Diego, Donnelly, ID and Boulder, UT, for example).
