2022 Hyundai Kona Electric

My hybrid or power battery failure, my EV Hyundai Kona from October 14, 2022 up to now in maintenance at the dealer “Keyes Mission Hills Hyundai.” They withdrew every month the lease amount, from my side I pay monthly lease and insurance for car and gap. Every time contact them just swiftly disregarding the whole call and promises in, even they didn’t call back with solution or updates as promised in the call. I wanna get a solution for all these. Stop draining my money, I’m still using my old car and paying for gas every week.

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.

This is a continuation of Complaint #11495997. Mon 12/05/22 AM - I could unlock the car, but it wouldn’t start. I jumped the 12v battery and drove car for about 30 minutes. Tue 12/06/22 AM - Car Completely Dead. I called Hyundai Roadside Assistance who sent a AAA technician who jumped 12V battery. I drove car for about 45 minutes to charge battery. I left a message with San Leandro Hyundai - Service & Parts Center about bringing car in and getting a loaner car, and am waiting for a callback today.

The following was posted on 12/5/22 on Kona Owners Forum: "USA location. Have a '22 Kona (EV; but, that apparently that not relevant to problem). Horn stopped working at about 7500 miles. Immediately made appt with dealer. On day of service there was another 2022 Kona (gas powered) in shop for same thing. Since I only have one car and wife with Alzheimer's, dealer checked obvious things and released me, saying the other owner could leave their Kona for detailed diagnosis. Dealer reported back to me that they believed they had found problem with other Kona, ordered part and would let me know if problem would be solved for the other Kona. If problem solved they would replace my part, of course under warranty. Today I was informed part didn't fix other Kona. So, I am without horn and dealer back to square one. Dealer said there is no recall and no tech bulletin addressing this problem. I can see from forum history that many have experienced a failed horn. HAS ANYONE EXPERIENCED A SOLUTION? If so, please share solution. Dealer welcomes any info I can provide. I think I will also report this to US Dept of Transportation, since 'no horn' is a safety hazard and may in fact be illegal.

The 12V battery keeps draining on this 2022 Hyundai Kona Electric. This problem happened when I owned the car for 7 months, I believe the battery management system from Hyundai caused the ruin and drainage to the 12V battery. It has happened 10 or more time ever since the battery keeps draining and Hyundai refused to take any responsibility in their faulty 12V battery.

The car turned into a bricked mode 3 times after I fully charged the car to 100%. The car cannot open or start the engine. The battery was dead or drained somehow. I have to jump start the battery and reset the battery terminals in order for it to work again. Now the braking warning light has stayed on after I reset the battery terminals. I think this 2022 Hyundai Kona EV has some electrical issues that Hyundai need to fix or be aware of.

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.
