2022 Kia EV6

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.

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.

The taillight came loose and every time i take it in to get checked or fixed at the dealer they ignore me, so i went in and tightened my self. there were 4 nuts already off and inside my trunk and there was no loctite on the bolts holding the light on. now the lamp is leaking water into the trunk and the tail light has water inside of it.

Vehicle Safety Complaint My Kia experienced an ICCU (Integrated Charging Control Unit) failure and was at the dealership for approximately two months while awaiting repairs. The ICCU and related components were replaced, and I was told the vehicle had been repaired. However, immediately after I received the vehicle back, the “Check Electric Vehicle System” warning illuminated again. Since that time, the vehicle has continued to experience serious electrical issues. The vehicle has unexpectedly shut off while stopped at red lights and has failed to restart on multiple occasions, leaving me stranded. This creates a significant safety hazard because the vehicle can lose the ability to move while in traffic, placing me and other motorists at risk. I have returned the vehicle to the dealership twice since the ICCU replacement, but the problem has not been resolved. The dealership has been unable to identify or permanently repair the defect. I have been without my vehicle for nearly three months this calendar year due to this issue. More importantly, I no longer feel safe driving the vehicle because I cannot trust that it will remain operational in traffic. I am submitting this complaint because I believe this represents a serious safety defect involving the vehicle’s electrical system and propulsion system. I request that NHTSA investigate this issue to determine whether other Kia owners are experiencing similar failures and whether additional action is warranted to protect consumers.

The front lower air dam and felt underguard detached while driving at highway speed on an interstate. The panel dropped and dragged on the pavement. I secured it with duct tape and zip ties at the roadside in order to drive home. There was no collision and no impact with road debris. The bumper fascia directly above the panel is undamaged, with no deformation and no paint transfer, which is not consistent with an impact and is consistent with failure of the panel's mounting fasteners. The panel shows longitudinal drag scoring on the underside and outward flex-fracture of the mounting clips. The right side detached first and the left side remained held by a single screw. The component is available for inspection on request. There were no warning lamps or messages before the failure. I brought the vehicle to a Kia dealer in [XXX] on XXX, at approximately 40,000 miles and within the 5-year/60,000-mile basic warranty. The dealer's technician identified multiple fractured mounting clips, of which only two remain intact. The dealer declined to submit a warranty claim, citing evidence of impact, and reattached the panel using added screws. The fractured clips were not replaced. The dealer's paperwork records the vehicle as repaired, but the technician verbally advised me to drive carefully because the underlying fastener failure was not corrected and the panel is not held by its designed fasteners. I opened a case with the manufacturer's consumer assistance center on June 9, 2026 (case number XXX) and submitted photographs as requested. I have received no substantive response in six weeks. A body panel that detaches at highway speed and drags on the roadway is a hazard to the vehicle behind it and to my control of the vehicle.

1. Severe Safety Concerns (Battery Thermal Risk & Component Interdependency) The PTC (Positive Temperature Coefficient) heater in my vehicle has failed. This component failure has completely disabled my vehicle’s air conditioning (AC) system. In the Kia EV6 architecture, the AC compressor loop is not merely a cabin comfort feature; it is intrinsically linked to the vehicle's thermal management system responsible for cooling the high-voltage traction battery pack. California temperatures are projected to hit 110°F immediately. Without a functioning AC system, the vehicle cannot execute critical battery cooling procedures. Yesterday, when plugging the vehicle into a charger, the high-voltage battery became alarmingly hot. Forcing a lithium-ion battery pack to accept high-current DC fast charging without operational coolant loop heat rejection poses an immediate, catastrophic risk of thermal runaway and vehicle fire. I am terrified to operate, park, or charge this vehicle in upcoming extreme summer conditions. 2. Predatory Maintenance Plan Tie-In Offer Yesterday, the dealership called and acknowledged the issue. They offered to cover 70% of the diagnostic and repair labor costs under corporate goodwill, as I am technically out of the standard warranty period. However, they applied an unfair and coercive condition: I am only eligible for this safety assistance if I purchase a mandatory 2-year maintenance contract costing $120 per month (totaling $2,880 over 24 months). Because the EV6 is a fully electric vehicle, its routine maintenance profile is virtually nonexistent. The dealership explicitly stated that this contract would exclusively cover tire rotations. Charging nearly $3,000 for tire rotations as a gatekeeping mechanism to fix a dangerous battery cooling defect is highly exploitative. The cost of this forced maintenance plan essentially equals or exceeds paying for the entire repair out-of-pocket, rendering the "70% goodwill coverage" an empty gesture.

Incident

May 21, 2026

On the night of [XXX], the vehicle was plugged in to AC charge at my home charging at 7.5kw (32 amps/240 volts). The next morning, the dedicated breaker to the EVSE was tripped, and the EVSE was damaged and unusable upon resetting the breaker. The car had charged approximately 20% before cutting off. A new EVSE was ordered and arrived by that night, however the car would not accept a charge, and displayed a "charging failure" message, despite the new EVSE working on two other electric vehicles. Additionally, the vehicle to load (V2L) functionality was compromised, and the vehicle displayed an error message when attempting to use the V2L. The vehicle was taken into Kia service center located in Mission, KS on 6/29, and diagnosed with a broken ICCU, which is scheduled for service on 7/1/2026.
