I saw mention of this on an unrelated group, didn't see it here, presumably this is a simple software update but I've seen no details yet.

Thread 'Another BMS recall for the Kona'

Apr 13, 2026

I heard wind of another BMS recall and sure enough, after checking my Vin# with Hyundai, they want to run some diagnostics on it. 2019 Kona EV
Checking for battery cell damage and updating BMS software I think. Sounds like the current BMS S/W may lead to over heating/charging and cause a fire in super rare cases.
