Hey everyone,
2022 Kona EV owner here. Took our Kona into Hyundai for its second scheduled maintenance and I asked for the gear reduction oil to be changed as well after reading this forum. Car is at just under 40,000km after 18 months of ownership and it has (had) been 100% perfect not even one minor issue.
Went in to dealership to pick it up as I was in the area, and noticed that they had the kids car seats out and the back seats unfolded and when I inquired why they said because in order to do the reduction oil change they needed to disconnect the high voltage battery. Strange but ok. So come back two hours later and it’s finally done and the service guy says yeah that was our first time doing that it’s a big process had to wear anti static suit and disconnect big battery. I just said oh ok and went on my way.
we live 100km from the dealership and 80km into my drive home and with 45% battery left the car displayed a turtle on and said limited power, stayed like that for a minute and went away.
so next day had it towed back to dealership, dealership now claims that they did NOT disconnect the high voltage battery and they have completely changed their story now that I explained what’s going on. So that’s a bit sketchy.
Few days later they call and said it was just software and they did some kind of software update to the car pertaining to hot weather battery performance, claimed it was all a big coincidence and that it’s all fixed now.
We knew it seemed fishy but we went with it, car was good for a few weeks maybe 500km or so no more turtle mode and now today on a highway drive went into turtle mode 20 times within 60km and with 30-40% battery left.
also when we were getting the car back I asked them for a print out of the battery state of health. They printed one out for me that said it’s at 100% state of health after 39,500 km. Isn’t that strange too?
anyways so yeah now we are at home will call dealership tomorrow morning again and send it back. Sucks that it worked absolutely perfect until the dealership laid their hands on it.
just thought maybe someone would have insight and wanted to share. Thanks for your time.
