I suppose the BMS is doing his work to stop any issues with the battery. I'm still waiting for the recall and see where this take us, the only solution I don't want to see is a reduction of range because I will be regretting not getting the Model 3 :'(Who wants to Beta test the new BMS update?!?! Anyone???
I thought the major point of the BMS update was to tighten diagnostics and identify packs that were at risk and needed replacing, so they could be fixed before they became fireballs... so the fact that we have cars getting flagged like this is not the least bit surprising to me.
This would indicate an issue with the packs as I have suspected. I am starting a new thread on the specifications of the cells themselves:
After BMS update (15-oct-2020) by automaker then some KONA stop and comfirmed will need to be replacement whole hi-voltage battery pac at korea.

it sounded to me from the media info that the fire problem was more probable if charging was to 100%.
i only charge to 80%, so i am not too worried. but still want to hear the problem solved.
i have a kona 2019 ev in new york state. i called the local hyundai dealer and they were aware of the recent recall(not just the bms update). but they had no directions from hyundai as what do do. they will call be when they get that and in the meantime i could call them every so often for any updates.

I wouldn't worry about it.. I'm not changing my charging habits because of a few fires in 77000 cars... I know that my cells are within .02 volts, so I should be fine..Mine is a 2021 Preferred, manufactured on June 17th.had the right equipment I also charge to 80% unless planing a long trip - like tomorrow - for three days! When started to charge from 56% my "check EV" light came on inside and the charger stopped charging. The light around the charge port blinked in red. I drove the car to the dealer who run the diagnostic. While waiting for him to get the diagnostic scanning gear the light went out. The scan showed no problem. Go figure. I was pleased that he had the right equipment and new he operated it with confidence. He made a note on the car's record and sent me away. Now the charge is at 90% and 448km. I think I will stop charging. Darn I need the distance tomorrow! The timing sucks. Just to be safe I will leave the car outside of the garage overnight.
Can somebody tell me how to set the time on my Bluelink? It is 5 hrs behind Eastern Daylight Time. Hawaii time?

Oh boy, Lars I think you may have the distinction of being the first 2021 Kona (post March 2020) with a traction battery failure. So sorry for your troubles.The new charge circuit did not fix the charging problem. My car is now back at the dealer, waiting for a new HV battery.
It may be, curious as to the pack build date and related info off the pack label (Part# and BMS ROM ID). I wonder if Lars obtained that info (hopefully), and it does not correspond to any of the recall listed packs detailed here:Oh boy, Lars I think you may have the distinction of being the first 2021 Kona (post March 2020) with a traction battery failure. So sorry for your troubles.
Can you phone the dealer and get them to supply you with the label information off the pack? ( part#, BMS ROM ID and Manufacture date) unless you already recorded that info.You know the good thing is, if any, that the problem showed up while the car is "new" (3,600km).
Here is a quick recap:
On Oct. 22 I took the car in with the complaint that charging stopped at 55% SOC. A diag scan on that day indicated a "cell overvoltage" - as in past history? - but completed with all test OK. It did not indicate a charge problem at all. I took the car home, it charged to 80% no problem.
On the evening of the 25th the charge stopped again - back to the dealer. The second scan, on Oct 26, must have prompted the dealership to order a new 'charge controller'. After they installed the new charge controller (fresh off the boat) yesterday afternoon, the car was left charging overnight to make sure everything is a OK. As it turned out it was a good idea, because charging stopped at ~50%. Roughly the same SOC as the one I took the car in with as a problem.
But we know know that the source of the problem was not the charge controller after all.I wonder how accurate the diag scans really are?
The service manager said "strange, you car is not on the recall list ...hmm".
In any case my dealer was excellent in looking after me. No complaints there.

I do not have that info. I will ask the dealer tomorrow. Hopefully they will give it to me. They also told me that because of the weight of the pack they are not equipped to safely swap it. They will have to send the car somewhere to do that.
Money well invested by the dealer. Judging by the way things have been going, I suspect the lift device will become a very handy and well used toolThey required my dealer to purchase a special lift table to perform this job. Evidently around 5kUSD$.
I am wondering if pack removal will ever be something that one could do at home. Unless you had a palette jack or some such, the answer is probably no.

It's inelegant, but I have seen some YouTube DIY types swap battery packs in a home garage setting (one chap in Finland (I think) with his Leaf...plus Rich Rebuilds from his early days are two examples that come to mind).They required my dealer to purchase a special lift table to perform this job. Evidently around 5kUSD$.
