There was a parasitic or phantom drain on my 12v battery (after 7 months 6K miles) - DEAD. A dealer service tech determined it to be the Harman Kardon radio (KONA EV Limited). Drained 3 batteries before it was found to be the culprit. Radio on backorder with no sign of ever showing up. Car has been at the dealer long enough to trigger the lemon law in CA. Considering the buyback as I have made two lease payments without the car in my possession6 weeks.

After only having 2300 miles on my 2022 Kona electric I received a warning indicator on my dash, -??Electrical system error.-?? I looked in the manual and was directed to take the car to the dealer. The dealer diagnosed the issue and shared that the battery itself is defective and a new one will need to be ordered. As a result, I began some online research into the issue. It appears that similar issues arose within previous year models, and some even resulted in fires once the battery reached 100%. I also read other stories about how batteries had inconsistent charging rates. I Experienced an issue with inconsistent charging rates prior to the error message but assumed it was simply me not remembering the percentage it was at when initially plugged in. After reading the issues I quickly realized it was not a fluke. I also felt it important to report bc I asked the dealer if they had encountered any other issues with the Kona EV and it-??s battery units and they said no. Obviously, this was before I did my own research, and am more very surprised they said they have had no other issues knowing that their copy recalled nearly 100,000 cards recently for faulty batteries.
