At the pack level I can't imagine why wouldn't be. At the module (10) or cell level (294) it's unclear.
Stopped KONA) After lasted BMS update - we found 7th cases..

I had the same message at the fast-charging station and 12V battery replaced because it is a fault, the gear not connected, after the message coming again the same situation and then replaced HV battery. Kone 2019 drive 73 00 km. After both batteries replace all work well, hope that the new HV battery works better than the original. Maybe the same error message can mean a different, have to check the battery by an office service station and if the battery is fault importer maybe report factory and so on.

You are correct. However, until there a definite knowledge of the source of the problem, it can not be corrected. Replacing thousands of batteries with new ones with the same self destructive possibility is not a solution. So the matter at this point is purely academic.
It is interesting to note that neither the Hyundai nor GM stopped making the Kona/Bolt respectively. Both cars are at dealers, available for sale. And there is no news of change of battery supplier or battery chemistry.
Hyundai electric car sales are down in January. Is this a blip or is the result of battery issues?

I think they are trying to fix the issue 1 by 1 rather than recall the whole 77000 car. And some owner only charge their car to 80% to prevent the problem. Possibly They know the problem by inspect the failure battery, but keep it in house. Kona was stopped selling in Korea right?

If it is true that the fault for the fires lies with the supplier of the separator, which does not meet the specified technical requirements, as well as the incorrect parameter of the maximum voltage difference between individual cells in the battery (the synergy of these problems leads to an internal short circuit in the cell, because the defective separator is damaged by dendrites, and the software set to 1V voltage difference, instead of 0.1V, is not able to detect and block the damaged cell in time), only a massive repair action (replacement of all affected batteries) could save Hyundai's opinion and protect the company from potential legal and market problems, which will be far greater than the estimated cost of the corrective action ($ 1.1 billion). Let me note that the window of the relative oligopoly on the EV market closes, and that Hyundai has not used it for promotion enough. If a fully equipped Hyundai Kona costs in practice the same as a medium equipped Tesla 3 or Mustang Mach-e, how does Hyundai want to achieve market advantage and high sales? These models are as incomparable as Hyundai and Genesis in terms of the standard of finish and comfort, even if on paper they perform very similarly. This year the market will be practically flooded with new EV propositions and Hyundai/Kia will have to stand on their eyelashes to maintain market share, and even to maintain sales growth in absolute numbers. And the following years are even more difficult, because the Chinese are just around the corner, who will hit the markets with their attractive models like a young boar in a cabbage. The scandal with burning Hyundai cars and the scandalous treatment of customers, the helplessness of the factory repair system and blaming subcontractors (even if this is true) will not encourage customers to accept the Korean concern's offer, despite its really good opinion so far.
However, it may turn out that despite the above-mentioned reasons, Hyundai is still not completely sure about the cause of the fires and is still waiting with decisions for final conclusions. Or that he just wants to sweep the case under the rug and to dazzle the market with a new platform in the hope that customers will forget. It may be difficult, however, because competitors will not forget to ask innocent questions that hit the image of the concern with the force of a tsunami. So maybe it's better to fork out a handful of coins and deal with honor, cutting off competitors from the source of easy gags. Everyone also always have to bear in mind the risk associated with the introduction of a new platform - and what if it also starts to create problems that will not allow to forget about the burning/bricked Konas and only further worsen the company's image?

I am not sure is is true. But it would look stupid. They don't sell it at home so they can burn and or experiment on cars in other parts of the world? Basic rule: if you have a problem you want to analyze it close to home.

Absolutely! You want to correct the root cause because you want to go massive in EV. My coworkers asked me about my bricked Kona, and clearly stay away from Hyundai. After 2 years , Kona EV now sitting at the dealer, already got thousands dollars discount.

Not sure it is relevant, to our Konas but on the Bolt forum there is talk about a First and Second Design Battery. The Second Design batteries have a female and a male connector for battery cooling - see picture. The first design used two female connectors. Speculation is that Bolts built with Second Design battery are OK. But no one is sure.

Chevy Bolt had a upgraded battery before with increasing range right? Something related with new chemistry inside the battery.

My Kona is now chang the original fault HV battery to the new one but I not know is that new battery exactly the same as the original was. I hope that the new one is improved maybe. I am interested in that kind of information for the new replacement batteries for Kona.

Where are you ? How long does it take for the battery to arrive? Mine is no ETA on replacement battery. Ordered 2 weeks ago

I am in Finland, HV battery coming in two weeks, all batteries transport in groupage so them coming when groupage coming. After that, I wanted four weeks for the 12V battery.

Hey, Markku,
Talk to your dealer to make sure they have all special tools and the hydraulic jack needed to remove the old and to install the new battery. And those stupid "one time use bolts".
In my case all these were shipped in four (4) different shipments to the dealer. The bolts supposed to come in today, but today is a holiday here in Ontario.

Hi Lars, I read your story and I remembered my dealer some things, bolts that have to change and software update and so on. The battery is now changed and I hope it working well for more years and kilometers than the original. I mention many times that nobody knows is the new battery different from than the original.
I purchase an ODB_II dongle to check batteries if it is possible to know something earlier than journey stop accidentally for faulty batteries.

Do I read you right? Are you rolling again on the new battery?
The ODB II dongle is a good idea. I will get one myself. I saw my dealer used one I will ask him which one he uses and what software. The dongle and the software may be provided to them by Hyundai.
We got 20cm snow over night. The first real snow fall this winter.
