(1) If main (big) battery out of warranty needs replacement in my 2022 Kona EV, what would be out of pocket expense? (2) I don't have extended warranty, potential buyer wants to know of full Hyundai warranty of 100,000 miles on big battery transfers to new owner - anyone know?

I saw a price online at an OEM retailer of about $9K. No idea what a dealership would charge but their prices are significantly higher. Also, there would be dealer prices for installation. It would be steep.

I would buy a battery and DIY the install because I have a background of advanced vehicle repairs and high voltage systems.

You could buy the battery and have an independent EV shop install it at some savings.

HOWEVER - you don't generally need to replace a battery at all. The 100K mile/10 year warranty ought to cover you pretty well. Also, there are cars (Kona, Niro, Chevy Bolt) who have the same or similar LG battery approaching 200K miles reporting 10-15% degradation. In other words if you treat the battery well, you should be fine.

ALSO - these batteries can be repaired. If one cell fails outside of the battery warranty, an EV independent shop can disassemble these batteries and replace a single cell. I don't know the cost of a single cell or the cost of the labor. There are many YouTube videos that show the disassembly of EV batteries for small repairs like cell replacement. If you need suggestions, i can post some links. One video talked about a Nissan Leaf battery repair a few years ago. I believe the cost for a cell replacement to be less than $500 in that video.

Another option is a battery from a wrecked Kona. I'm not sure they are easy to fine but surely they exist. I'd still have any batteries from wrecks to be inspected to make sure the cells inside didn't move or weren't damaged. I saw one video about a different brand EV which was in a collision. The rear stack moved and had to be disassembled, inspected and reassembled.

I was hugely concerned about the very same things when I began my EV journey. I did not want to spend X money only to discover that repairs would cost 2X later. We bought a used '21 Kona with the 64 KWH battery. We have driven it about 11.5K miles since May with zero issues.

Also, there is a US federal law that requires all EV batteries to be warranted for 8 yrs, 100K miles regardless of which owner has the car.
