My ICCU failed while I was driving and I lost power while in a light controlled intersection in Chicago. The screen turned off and I could not see my speedometer or any driving information. I luckily was able to roll to the side of the road and park the car. My car could not change gears, doors would not work, trying to jumpstart the 12V did not work.
Started car. Heard a pop in the back seat area and then an error message appeared on the dash.
I had an ICCU failure. There were no warning lights . The dealership initially could not find the problem but when I brought it back again they did confirm the ICCU failed and replaced it. Failure of this causes the car to stop driving and lose power causing you to stop on the road as well as be unable to charge the car.

In November 2024, my 2022 Kia EV6 became suddenly non-drivable due to electrical failure consistent with a repeat ICCU/12-volt system malfunction. The vehicle would not start or maintain normal electrical power and became stuck in accessory mode, creating a loss of propulsion and complete loss of transportation. This vehicle previously experienced an ICCU failure earlier in 2024 that required dealership repair and battery replacement. After that repair, the vehicle again developed electrical failure symptoms, including loss of 12-volt power and inability to operate. Due to the unsafe non-drivable condition, Kia Roadside Assistance directed and arranged a tow to a Kia dealership. Upon arrival at the dealership, new undercarriage and wheel-well damage was documented within approximately 90 minutes of drop-off. This damage was not present prior to towing and is located where tow equipment attaches. The vehicle remains in the possession of the dealership and is available for full inspection. The electrical failure created a safety risk because the vehicle became immobilized without warning and could not be safely operated. There was no advance notice or driver-caused event. The failure resulted in complete loss of vehicle function. The vehicle has been inspected by a Kia dealership, and I have been working through Kia corporate and roadside providers since the incident. The vehicle remains out of service with unresolved electrical issues and unresolved damage resulting from the manufacturer-directed tow.
Not charging on Level 1, Level 2 chargers, only level 3. ICCU problem confirmed by dealer diagnostic even after recall software update was installed.
MY DRIVERSIDE FRONT DOOR WON'T OPEN, WHEN DOOR IS UNLOCKED, BOTH OUTSIDE AND INSIDE HANDLE WONT'T OPEN THE DOOR. YOU HAVE TO CLICK ON THE UNLOCK/LOCK BUTTON 15-20 TIMES TO GET THE DOOR OPEN. ALL THE OTHER 3 DOORS WORKS FINE.

My 2022 Kia EV6 developed a serious electrical/MCU malfunction on 10/19/2025 at approximately 64,300 miles. While driving, the vehicle began to stutter during acceleration, all driver-assistance and safety systems disabled (LKAS, collision avoidance, lane keeping), and the vehicle could not accelerate normally (topping out around ~60 mph when fully pressing the pedal). The Kia Connect app displayed fault codes MCU P0A4100 and LKAS C164286. The malfunction recurred immediately after a dealer visit on 10/20/2025. The vehicle has since been inspected by Huffines Kia in Corinth, Texas, but no confirmed diagnosis has been provided, nor have they notified me of dropping/reconnecting the HV battery. On 11/18/2025, a new fault code appeared: MCU P0C1700. This failure affects the high-voltage electronics/MCU and causes sudden loss of acceleration capability and complete disabling of active safety systems while the vehicle is in motion, placing me and other drivers at risk. The issue is reproducible, continues to occur, and the vehicle remains at the dealership. I am requesting NHTSA review of this electrical/MCU malfunction as a safety-related defect.

The ICCU (Integrated Charging Control Unit) failed while the vehicle was charging at my home. It tripped the 60A circuit breaker for my EVSE circuit and now my EVSE is inoperable. The vehicle no longer charges via AC (Level 1 or Level 2) at any charging station. Attempting to charge the vehicle triggers a safety fault error on the EVSE indicating an electrical problem with the vehicle. Additionally, attempting to use the V2L (Vehicle to Load) adapter on the vehicle causes audible arcing sounds from the ICCU accompanied by a "Check Electrical System" message on the vehicle's display. These symptoms indicate a complete failure of the OBC (On-Board Charger) circuit inside of the ICCU. The arcing is most likely coming from a failed MOSFET. The ICCU has been recalled twice in this model, however it is clear that the software update "remedies" are not satisfactory. I had the most recent recall campaign SC327 completed during the month it was released in November 2024, yet it still failed only a year later. Reports of ICCU failures are constantly being posted online from "remedied" Kia EV6 vehicles. Software cannot fix a hardware design fault. The part should be redesigned to correct the cause of the defects and, if Kia doesn't want to replace every ICCU with new hardware, the warranty on the ICCU should be extended to unlimited miles and 15 years.

2PE23012 · Loss Of Motive Power
Opened Jul 3, 2023 · Closed Apr 17, 2024
Status: closed (inferred from source dates) · Electrical SYSTEM:12V/24V/48V Battery; Electrical System:propulsion System:dc/dc Converter
On July 3, 2023, the Office of Defect Investigation (ODI) opened PE23012 to investigate allegations of loss of motor power on model year (MY) 2022 Kia EV6 vehicles. Some consumers reported loss of motor power immediately after warning lamp illumination or reduction of motive power while the vehicle was in motion. This investigation found that the Integrated Charing Unit (ICCU) may become damaged over time from transient high voltage and thermal cycling. A damaged ICCU may not be able to charge the 12-volt battery which can discharge gradually while driving with a reduction of motive power. The vehicle could eventually experience a complete loss of motive power thereby increasing the risk of a crash. On July 13, 2023, Kia conducted a service campaign to inspect the ICCU and install an improved over-current detection software logic in certain 2022-2023 EV6 vehicles. On March 15, 2024, Kia filed recall 24V-200 for 48,232 MY 2022-2024 Kia EV6 vehicles. The recall remedy provides an inspection of the ICCU, and if necessary, a replacement of the ICCU and the associated fuse. The ICCU software reduces the risk of overcurrent and implements voltage peak reduction at the end of EV battery charging. The recall also includes a software update that revises the electric water pump operational threshold to reduce thermal loading during charging and driving. In view of the recall action being taken by Kia, ODI is closing this Preliminary Evaluation. The agency reserves the right to take additional action if warranted by future circumstances. To review the reports cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.

Status: closed (inferred from source dates) · Electrical System:propulsion System
NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.
