I bought Kona EV 2020 in Apr 2020. It does not charge. Inspection by dealer the second time indicates Cell problem. Hyundai has asked for a test drive to see what is wrong and this will be the third visit. I have a Charge Point level 2 charger at home and charge my Tesla and Kona on it. Have had Tesla for a year with no problems at all. Is the cell replacement of the battery within 4 months going to effect the longevity of the battery?? To what extent?
Battery Issues Kona 2020
If it is indeed a cell issue within the HV pack ( due to voltage differential or insulation test failure), the longevity of the battery will definitely be impacted as the present form of repair is to replace the pack itself. I believe there are 2 already recorded on this forum. The defective pack will be shipped to Hyundai for I assume rebuild at the cell level after the new one has been shipped and installed.

They are not going to replace just one of the individual 98 cell pouches at the dealer level. In theory the dealer could replace one of the 5 cell groups that has the offending cell but in all likelyhood they will replace the entire battery pack with a new one and ship the old one back to be refurbished. I am not surprised Hyundai wants a second opinion, the cell groups are retail new part priced at $7000 and entire pack is $25,000 US dollars. Not saying that is their cost but you get the idea that this won't be a cheap fix.

Replacement obviously won't be an issue even if it were used as a Taxi at this point, however the time to actually have the replacement installed has not been determined yet

Hi,
Been two months and Hyundai keeps giving future date to arrival of battery at dealer. Now it is Nov 23, 2020 (Defect since Sep). Unluckily we do not have the lemon law to force the company to buyback such vehicles. Anyone have a similar experience or knows the method to make the company buyback the car??

Hi,
Been two months since replacement battery has been ordered and Hyundai keeps giving future date to arrival of battery at dealer. Now it is Nov 23, 2020 (Defect since Sep). Unluckily we do not have the lemon law in BC Canada, to force the company to buyback such vehicles. Anyone have a similar experience or knows the method to make the company buyback the car??

I feel your pain. It took 10 weeks for my battery to arrive, but I did get my car back last week.
That arrival date almost identical to ericy's replacement wait time.
Hopefully the dealer will have the other associated equipment (lift table) and coolant on site as well.

The difference was that in my case that the couldn't supply an ETA. They just said the thing was backordered, and then out of the blue we found out the thing had been shipped. The dealer had been on the phone with Hyundai about something else, and they just casually mentioned it.
The pack replacement procedure could be modified with this new equipment to save time:
