I am by no means a battery expert. But I have looked around for any info I can find on the battery issue.
Here is some sort of a timeline so that others can form their own thoughts on whether or not they think this is related to the previous issues:
1. March – August 2019. Hyundai received reports of vehicle fires (Korea, Canada and Europe).
2. September 2019. Joint investigation with HMC and KATRI. the Korean safety authority.
3. March 2020. Hyundai releases update for the Battery Management System. BMS software updated to detect early abnormalities in the battery state while the vehicle is parked. Software update developed jointly with LG chem. Hyundai starts collecting and analysing battery packs collected during the campaign.
4. March 3, 2020. LG Chem has “remedied” the folded anode issue by adding extra insulation. google report "RCLRPT-21V127-1095" This date is important as it is the cut off for all of the recalls. Essentially the safety authorities say the "fire issue" has been solved if you battery is manufactured after this date.
5. April – October 2020. Additional reports of fires (7). HMC continues review and study with KATRI. Looking like electrical shorts. Confirmed that previous software update was successful in early detection of internal short and disable vehicle. This seems to be what happened to my 2021 Kona.
6. June 11, 2020. The battery management system is upgraded and applied to older konas and all new production?

8. October 2020. US mandatory recall to update BMS software and inspection of battery packs. Advisory to park outdoors. Affects 77000 vehicles manufactured up to March of 2020?
9. October 9, 2020. Hyundai QC admission?

10. October 13, 2020. Business details about Hyundai, Mobis and HL Green power over the recall.

11. November 2020. My 2021 KONA Battery was made. Has HL GreenPower on the label. H stands for Hyundai and L for LG. Hyundai is still making the batteries for Konas with the same LG cells (although perhaps mods to catch production issues and a better BMS to stop fires before they start?).
12. November 16, 2020. Some info on Hyundai’s plan for Mobis and HL Green Power.

13. Jan-Feb 2021. A Kona with updated BMS caught fire at 100% charge. Found internal short. Folded Anode in cell.
14. February 12, 2020. Rumor from electrek.

15. February 23, 2021. LG Chem separator cell issue was discovered? (world wide? Except canada) North American recall of all potentially affected vehicles. Only includes 2019 and 2020. This is the battery replacement recall.
But does NOT include 2021 and later model years. http://www.thelec.net/news/articleView.html?idxno=2420 This article and the excerpt form the ministry of transport in Korea seems to place the blame on the battery anodes. LGChem denies this as it had corrected that problem long ago and tried to replicate the problem but was unable to start a fire.
16. April 21, 2021. Hyundai to stop making Kona’s in Korea.

17. May 28, 2021. Closes July 2021. Hyundai Mobis buys all of HL green power.

19. August 3, 2021. Looks like a KONA in korea caught fire after having the recall updates and a replacement battery.

20. August 20, 2021. GM recalls ALL Chevy BOLTS for battery replacement. They also use LG Chem cells, different, but similiar manufacturing process?. Found 2 issues, but don’t specify (folded anode and separator?)
https://my.chevrolet.com/how-to-support/safety/boltevrecallView attachment 13323Looks like GM is upfront that they may be providing "refurbished batteries" to bolt owners...
21. LG Chem just lost 8 billion dollars of share price.

22. Did GM just find the problem with their batteries. Folded separator?

23. Here is a great story of why GM suddenly had to do something about the bolts.

So. The "fix" seems to be to disable the vehicle before it starts a fire. This is what the transport authorities want to prevent and why there are safety related recalls. So, lets assume the BMS has fixed the fires...now the only issue is a disable Kona which becomes a owner issue and a warrantee issue NOT a safety issue. There will be no recalls unless more of these replacement batteries with updated BMS start to catch fire. See previous point 19.
Hyundai seems to have cancelled the Kona in Korea and then "re-distributed" them around the planet...Not dangerous...just potentially inconvenient when they shut down to prevent a fire and the owner has to wait months to get a replacement or make noise to force the company to do what is right.
This looks like the "not perfect solution". See point 9 above.
Presumably, all of us Kona Electric owners currently have warrantee coverage on our batteries. How will you feel when the warrantee runs out? Seems to me that these batteries cost $30K plus install...
