ICCU failure at 16k miles. The ICCU was replaced at the dealership on January, 29th of this year, so it is not available for inspection. The failure tripped a breaker at my home while it was charging possibly indicating a short circuit. The short circuit could have potentioally overheated and caught fire in my home. I took the vehicle to the dealership and they confirmed it was the ICCU and replaced it under warranty. I have a copy of the invoice received after the replacement was installed. I do not know what they did with the old ICCU after it was placed. There was no indication of pending failure that I noticed prior to this incident occuring.

The contact owns a 2022 Kia EV6. The contact received notification of NHTSA Campaign Number: 24V867000 (Electrical System) and the vehicle was repaired at the local dealer. The contact stated that four months later while driving 75 MPH, there was a popping sound coming from the rear of the vehicle. The message to "Check Electrical System" was displayed, and the vehicle unexpectedly decelerated to approximately 45 MPH. The contact continued driving and the message to "Stop Vehicle and Check Power Supply" was displayed. The vehicle decelerated to 5 MPH and failed to accelerate as intended. The vehicle was pulled over to the side of the road and inspected. All the doors were unlocked, and the vehicle then stalled. The vehicle failed to restart. The vehicle was towed to a dealer where it was diagnosed and determined that the Integrated Charging Control Unit (ICCU) assembly and fuse needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 148,309.
The car has 41,000 miles and has experienced the second failure of the ICCU, so it will have a third unit in 3 years. The noteworthy issue is the risk associated with these failures. The unit failed on the freeway, and power was reduced to 20% (estimate), which put me and others in danger. This is apparently a known and signi…

The car has 41,000 miles and has experienced the second failure of the ICCU, so it will have a third unit in 3 years. The noteworthy issue is the risk associated with these failures. The unit failed on the freeway, and power was reduced to 20% (estimate), which put me and others in danger. This is apparently a known and significant issue with KIA. As a consumer, I am extremely concerned it will experience a 3rd failure, which could include immediate risk to self and passengers. How is this acceptable? Thanks for providing the forum to discuss.

Iccu failure and defective drivers seat. Was covered under warranty but took over a year to finish all defective parts. Still not 100%
The ICCU failed which was part of the recall. Kia is unwilling to honor repairs beyond the 100,000 mile warranty which is unacceptable because there is still no resolution and it is subject to potential future failure. I need an extended warranty.
The ICCU failed and had to be replaced. This is a known issue.

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.

DP22005 · Pedestrian Alert Sounds
Opened Jan 27, 2023 · Closed Aug 7, 2023
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.
