2022 Hyundai Kona Electric

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.

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.

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.

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 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 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.

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.

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.

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.

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.

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.

While driving slowly less than 5 mph into parking stall the vehicle accelerated excessively while trying to brake the vehicle it continued to accelerate and jumped the curb while i was still pumping the brakes to try to get it to stop and the car finally stopped after hitting the front of the establishment building. no collision warning went off at this time as well. i checked the mats to see if they were against the accelerator pedal and they were not.

The push door to the charging port locks and i am unble to open it. it will sometimes unlock if i push the unlock button several times. this is worrisome since i need access to the charging port to charge my batter. not sure if there is a design flaw with the latch to the door.

There were several recall/service notices on my vehicle. i brought car to dealer in may and they were unable to address them all b/c i was informed a dealer specific piece of equipment necessary for the recall had broken and they could not address that issue. why is it saying on nhtsa website zero unaddressed recalls for my car? here are some of the notices: service campaign 9a4: kona ev dtc inspection, bms update, and bsa replacement – dealer best practice august 29, 2023 i believe there was an additional issue of concern. i originally scheduled for early 2024 & then there was an additional recall/concern and i could not be accommodated until may 2024; however, as mentioned, they were unable to address all the issues at that time. please let me know.

During the winter the vehicle does not produce heat. there is a knocking sound from under the dash and only cold air comes out of all the vents. when it was 20 degrees out i measure 35 degree air out the vents over the couse of an hour drive. the car has been to the dealer multiple times for this issues. they have acknowledged the problem and have tried replaing different parts but the problem still occurs. it's very cold in the car when it's below freezing outside and it's difficult to clear the windows of fog, frost, and snow with no heat. the hvac system will make the knocking sound when turing on the car and sometimes when driving also. trying to adjust the temperature will sometimes trigger the noise. i feel the knocking sound and lack of hear are related.

Horn stops working.  it stopped working about a year into owning the car, then again a few weeks later. the horn seems to stop working after windshield wiper fluid is refilled; not sure if it's related though.  i have been in situations where i needed to use the horn but was unable to because it was constantly not working.
