Kia
Ev6

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.

Software updated for recalls still have ICCU failed.

The contact owns a 2022 Kia EV6. The contact stated that the electric vehicle battery failed to charge during level one or level two charging. The vehicle was driven to the local dealer, who diagnosed that the Integrated Charging Control Unit had malfunctioned and needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure, but no assistance was offered. The contact stated that the vehicle was previously serviced under NHTSA Campaign Number: 24V867000 (ELECTRICAL SYSTEM). The contact stated that the vehicle had experienced the failure listed in the recall. The failure mileage was 81,300.

The air bag (SRS) floor wire harness running directly under the moving front driver and passenger seats are assembled with no shielding or protection. So they are subject to being severed or damaged, and the wires are at risk of corrosion if exposed to moisture or road salt. This is clearly a preventable safety issue. However, Kia and Hyundai are not providing warranty coverage. And replacement of a damaged harness is ~$9,300+ because the harness apparently routs behind the dashboard and to the engine compartment.

Prior to midnight on 9/25/2025 I stopped at a Sheetz in Stephen"s City , Va to charge my 2022 Kia EV6. Upon pulling into the charging area I discovered construction fencing around the area with the chargers removed. I then drove to the other side of the store and parked next to the building to take advantage of the lighting as I scanned my phone app for alternative chargers in the area. SUDDENLY, within the blink of an eye, my car lunged forward at MAXIMUM speed. It came to a sudden stop , prior to hitting the glass and brick wall of the building. I was stunned. My first reaction was to try to go into reverse to back away from the building and then I noticed people coming toward me. I rolled the window down and heard them ask if I was ok , if I needed help calling 911, and then they began to insist that I climb down out of the car as they feared it would catch on fire. I did not understand what they meant initially, until I realized I was LOOKING DOWN at them. With assistance, I got out of my car and realized it was impaled upon the metal barrier post located in the middle , front of the parking space. The local sheriff dept responded and after putting me through all the DUI tests/exercises realized that I , indeed , was sober and not responsible for the incident. The deputy called Clem's Garage/Towing who arrived 30-45 min latter with a standard tow truck - I tried to explain that tugging at my car from the rear would not release it from the pole ( the rear of the car pointed toward the pavement while the front pointed toward the sky) and that continuing to tug would only do more damage (I wanted to prevent my car further damage). He eventually called another company who arrived with a large crane-like vehicle that lifted my car off the pole. The top portion of the pole was missing and apparently stuck in my car . My car was then towed to Clem's holding yard.
