2022 KIA EV6 Complaints

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.

Collision a avoidance warning randomly goes off while stopped a good distance behind cars at traffic light.

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

Heard a loud pop from rear passenger side of vehicle followed by dash warning lights to check charging system, then pull vehicle over immediately. All power to the vehicle was subsequently lost immobilizing the vehicle. Dealer service department said ICCU board needs to be replaced, but is on national backorder. Car has been immobilized since.

After driving my vehicle for a few minutes on my way to work my car lost speed rapidly, going from 40 mph to 25 then seconds later to 22 mph. I tried to accelerate; the car was unresponsive and would not accelerate over 22 mph. Dropping speed rapidly and suddenly during rush hour on a secondary road with a limited shoulder was unnerving as the slow response required waiting for a gap in traffic flow to safely turn around to head home. Upon returning home a message appeared on right side of dash board in an orange circle "check vehicle system" with a small upside down triangle with letters EV also inside this circle and a "small orange battery" picture showed on the left. I called Kia Roadside Assistance and reported the above and was advised it would take about 90 minutes for a tow to dealer as I was unwilling to drive it. Once the tow truck arrived I tried to drive EV6 out of my driveway onto flatbed and it died halfway. Driver had to jump 12 volt to get car to start and maintain power to get up flatbed. He advised 12 volt had to stay connected to ensure power to deliver to dealership. After weeks of calling / emailing dealer, opening a case with Kia America and sending several unanswered tweets the dealer advised on 06/02 that tech determined the ICCU assembly and a new high voltage fuse would be required. The service manager advised this would take 7-10 business days but on 06/15 advised the parts had still not arrived and in following up with Kia America there was no available ETA on when the part would be received.

Issue has been diagnosed by Kia and our dealership as a failed Integrated Control Charging Unit (ICCU). Parts are backordered indefinitely (we were told there's 106 on order nationally). Same issue as the Hyundai Ioniq 5 (which is built on the same platform): https://news.yahoo.com/highway-safety-agency-reports-power-162735107.html Car dash showed a "Check electric vehicle system" alert, followed shortly after by "Stop vehicle and check power supply" on a short city drive home. Was close enough to make it home without the car turning off, where I confirmed the car could also no longer be charged at home using AC charging. The ICCU manages AC to DC power conversion for home charging and also keeps the 12-volt battery charged. Per Kia's recommendation, had the car towed to the nearest dealership. The worst part is just the wait time for backordered parts that Kia and Hyundai; dealership can't even give us an estimate of when to expect the parts. 107 does not seem like a difficult number of components to come up with on short notice for a carmaker that sells 2.3 million cars annually.

Vehicle suddenly showed warning for electrical failure and could not longer be driven. Towed to dealership. Main fuse was blown. After waiting a couple of weeks for that part to arrive, it was replaced, only to find out that another component had failed; the ICCU. Kia stating there is NO ETA on when this part will be available. Car had been at dealership for almost 5 weeks with their admission that no estimate exists for when the car will be repaired due to the unknown time to wait for the part.

There exists a serious manufacturing defect in that the brake lights do not turn on when the car is used in one-pedal drive mode and even a rapid deceleration occurs due to regenerative braking. This was documented by Consumer Reports and it presents a critical safety hazard. https://www.consumerreports.org/cars/car-safety/brake-lights-can-fail-to-provide-fair-warning-on-some-evs-a9533519285/?EXTKEY=YSOCIAL_FB&fbclid=IwAR3N_MQOI4ZGHfHSf18eAJSE7Cx02eftIx2k8F_oKaVo19_YJKgYEn7yeOE

The contact owns a 2022 Kia EV6. The contact stated while driving 65 MPH, the vehicle shut off with the check battery warning message displayed on the instrument panel. The contact pulled the vehicle off to the side of the highway shoulder and had the vehicle towed to an independent mechanic. The mechanic performed a diagnostic test that showed that the integrated charging control unit (ICCU) had failed and needed to be replaced. The manufacturer was notified of the failure and provided a case number. The vehicle was not repaired. The failure mileage was approximately 8,000.
