Started my 2022 Kona EV as usual in my driveway in Southern California in May 2023. Vehicle started then flashed "Check Vehicle System (EV) failure code appeared. Car would not stay started. Had it towed to Dealer they kept if for 2 week and called me to say the vehicle was fixed and I could come pick it up. Repair Order said that the "EV Safety Plug failed upon testing" That was a Friday afternoon. Drove the vehicle home and it seemed to be fixed. The next day (Saturday) went out in the am to run errands and got the same code again and again it wouldn't run. Again had it towed to Dealer (with poor Hyundai Roadside Service). It remains there as I suspect the Dealer tried an easy fix instead of a major one. Will update with status. Already a California Lemon Law buyback situation. I'm not even going to try to work it out because the new car is not operating as advertised. Car is unreliable.

The electrical system is not fulling shutting down after the vehicle is turned off and the 12 volt battery drains. This also caused the Instrument Panel to fail and made the car not safe to drive as we had no speedometer or odometer. The battery drain happened over and over again. The car is a lemon. This car has been at the dealer since December 30th, with no fix in sight.

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.

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.

This 2022 Hyundai Kona Electric keep draining the battery after I charged my electric car overnight. It has happened 6 or 7 times now, which I think Hyundai needs a recall on this car. It killed the 12V battery after fully charged the car. Something has drained the battery completely. It is very annoying when this happened.

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.

I noted a sever drop in the full charge range. The battery meter does not reflect the true and accurate available storage. You can-??t depend on these readings.
