2022 Kia EV6

The 12V battery on my Kia EV6 has died 5 times (May 9, May 23, Jun 18, July 3, July 5 2023). I bought the car in March 2022 and there were no issues until May 2023. Twice the 12V died when parked at home with the Lithium battery at 80% charge, twice when my wife was out and parked and the last time at the 'Serramonte Kia' dealership in Daly City, CA. It required us to call Kia Roadside assistance to jump start the car. It was reported to Kia all 4 times that it happened to us. They recharged the car and when it finally died at the dealership, they replaced the 12V battery. I suspect that it's going to happen again because there's a fundamental problem with the ICCU which prevents the Lithium battery from charging the 12V. I have read that it's already been reported to NHTSA and that it's been investigate. Kia needs to recall and fix the underlying issue. I am worried that it puts my family at risk if we are stranded in the middle of nowhere.

The issue is essentially EXACTLY like this article: https://www.caranddriver.com/news/a44272155/2022-hyundai-ioniq-5-nhtsa-investigation/ We heard a semi-loud pop that appeared to come from the rear of the vehicle. Approximately 5-15 seconds later, we got a notice that the electric system needed to be diagnosed. We were only a block from the house, traveling at low speeds, and did not experience a complete loss of power. However, the system started giving additional alerts (I do not remember the exact phrasing) related to stopping the vehicle immediately.

On 5 May 2023 our 2022 Kia EV6 WIND AWD Automatic vehicle (~11,200 miles on the odometer) was being driven under normal conditions at approximately 30 mph in city traffic when the car lost motive power and a dashboard alerts appeared stating "stop vehicle and check power supply" and "check electrical vehicle system." The driver complied but the shutdown occurred on a heavily trafficked road and put the driver and other travelers at risk and caused the driver considerable distress. The incident was reported to the dealer and manufacturer via the Kia Access app, and the car was towed to the nearest Kia dealer and service center on May 8. The dealer diagnosed the problem as caused by a defective ICCU (a part of the electrical powertrain control system) requiring replacement. As of 12 July 2023, Kia has not provided a replacement part and it remains on backorder with no ETA for arrival. We have not been contacted by Kia and to our knowledge no one has inspected the vehicle other than the dealer service technicians.

The contact owns a 2022 Kia EV6. The contact stated while driving 35 MPH, the vehicle shut off and lost motive power. The vehicle rebooted and the message "Critical Electrical Failure" and "Stop Vehicle” was displayed. The low voltage message was also displayed. The contact was unable to stop the vehicle or restart the vehicle. The vehicle came to a complete stop independently. The vehicle was towed to the dealer for a diagnostic test however, no failure was found. The contact was informed that the vehicle needed to be diagnosed by a technician. The vehicle was not repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was 11,000.

HAD JUST CHARGED THE VEHICLE AT A LEVEL 3 CHARGER, RECEIVED BATTERY FAILURE WARNINGS ON THE DASHBOARD, BY THE NEXT MORNING THE CAR HAD LOST MOTIVE POWER DOWN TO 12 MPH MAXIMUM. THIS OCCURRED JUNE 19, 2023. THE CAR HAS BEEN AT THE DEALER EVER SINCE, WHERE THEY ADVISE THAT THERE ARE NO ICCU REPLACEMENT MODULES IN THE USA AS THEY ARE BACK ORDERED. THE DEALER IS NORTHSTAR KIA IN QUEENS, NY.

During Level 2, 48 amp charging the car continually stops and starts charging roughly every five minutes. After contacting the charging maker, their diagnostic showed nothing wrong with the charger or incoming power, and that the car was stopping the charge. My Kia dealer states it is a problem with the onboard charger. However, Kia support doesn’t seem to acknowledge it. I have seen multiple reports of this is happening including a potential lawsuit, so I’m reporting this as an issue as well.

Vehicle repeatedly interrupt its own charging, no error codes are surfaced. The charger(EVSE)is in proper working order, confirmed with other cars, the area around the plug gets very warm but not alarmingly so? The issue developed after many months of error free charging. The issue is non limited to a single EVSE, it seems to be avoidable by greatly reducing charging rate.

ICCU or 12v system has failed and car died mid drive on the road. Car is currently at the dealership for repairs. With complete electrical failure the vehicle reduced speed and stopped on it's own. This happened at night and I didn't have lights in or on the car to see. Additionally, I was unable to activate emergency lights and put on hazards. The dealership is struggling to diagnose the cause of the issue. The car dying was proceeded by a 12v battery light indicator and the turtle light saying it was reducing power. This was followed by a flashing "pull over vehicle and stop now" message.

On June 3, 2023 I found out that my EV6 was no longer charging, and that I could not open my doors or my trunk with my key fob. Nor could I start the engine. It turned out that my 12v battery was drained. As I never left my headlights or doors open overnight, I had no clue why the 12v battery was suddenly inoperable. I called AAA roadside assistance to have my 12v battery jumped. On June 4, 2023 my 12v battery had drained again, and I had to call AAA roadside assistance once more to have my 12v battery jumped. The earliest I could take my car in to the dealership for warranty-covered repairs was June 14. There, I was advised of the issues regarding the integrated charge control unit (ICCU). The dealership could not tell me when the part would arrive so they could replace it. I am currently using a rental car provided by the KIA dealership. Until the ICCU is replaced, I fear my EV6 could stop in traffic and leave me vulnerable to danger.

EV charging on Level 2 was overheationg the charging port, terminating the charging session. KIA released TSB ELE 283 software update. The software update throttled the charging so it only charges at half speed and does not overheat the port. To me this is a bandaid for faulty charging ports and that there is no guarantee there will be a failure of the port causing electrical failure and possibly even a fire. This was evaluated at the dealer and confirmed the charging speed is throttled. They could not do further evaluation unless I committed to leave the car for days, possibly weeks to work with KIA Tech Line to further diagnose. This is a known issue and others have had their charging port replaced after a lengthy stay at the service department. It appears this may be a bad batch of charging ports causing this overheating and failure
