There are 4 owner-reported engine complaints for the 2023 Kia EV6in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
On April 24, 2025, I plugged my Kia EV6 into my 48-amp hardwired ChargePoint HomeFlex at 7:26 PM. Around 10:30 PM I heard a noise outside but did not investigate. At 12:25 AM I noticed I had not received a “charging complete” notification. The Kia Connect app showed the vehicle at 74% and no longer charging. The ChargePoint app was unresponsive.\n\nThe next morning I found the charger’s 60-amp breaker had tripped. After resetting the breaker and rebooting the charger, the EV6 would not start charging and displayed no “Charging started” or “Charging unsuccessful” message.\n\nI then attempted to charge using a portable Tesla Level 1 charger on a 120V GFCI outlet. The EV6 briefly announced “Charging started,” but the dash showed no charging data. The outlet’s GFCI breaker tripped. After resetting, the breaker immediately tripped again when reconnecting the vehicle.\n\nI attempted to drive to a nearby DC fast charger. Upon shifting into drive, the vehicle displayed “Check electric vehicle system” and entered power-limited mode (would not exceed 20 MPH). I returned home. While backing into my driveway, the vehicle triggered a red alert with “Stop vehicle and check power supply.”\n\nThe vehicle was towed to a Kia dealership. They diagnosed a failed ICCU (Integrated Charging Control Unit) and high-voltage fuse. The ICCU recall issue is known for this model. Repairs took over two weeks due to parts delays. The ICCU and high-voltage fuse were replaced.\n\nThe ICCU failure also damaged my home ChargePoint charger, which required replacement under warranty
I received recall 24V867 from Kia dated 12/13/2024. The dealer alternately claims no knowledge of this recall, scheduled a service appointment to complete it, an today again claims no knowledge of the recall. Union Kia has put it on me to contact Kia America - that is not my job to correct their internal problems. Please advise.

1. **Component/System Failure**: The vehicle's cooling system is repeatedly losing coolant, suggesting a leak or malfunction. The system has not been officially diagnosed due to technician availability but is available for inspection. 2. **Safety Risks**: The frequent need to refill coolant raises concerns about engine overheating, posing a potential safety hazard during operation. 3. **Problem Confirmation**: The issue has been consistently observed by the owner, requiring coolant to be refilled three times in 49 days. However, a formal diagnosis by a dealer or service center has been hindered by a lack of available technicians. 4. **Inspections by Parties**: The vehicle has not yet been inspected by the manufacturer, police, insurance representatives, or other third parties concerning this coolant issue. 5. **Warning Signs & Symptoms**: No warning lamps or messages have indicated a problem prior to noticing the coolant depletion. The issue was identified only through physical checks of the coolant level.
Component/System Failure: The main components that failed or malfunctioned include the vehicle's charging system and battery management system, leading to significant range discrepancies and charging issues. Additionally, the coolant system issue suggests a failure in the vehicle's cooling system. These systems are available for inspection upon request to further diagnose and address the underlying problems. Safety Risks: The safety of the vehicle's occupants and others was put at risk due to the potential for being stranded in unsafe or remote locations, as experienced on [XXX], in Pennsylvania. The inability to reliably charge the vehicle and the coolant system issue could also pose a risk of overheating, potentially leading to engine damage or failure while in operation. Problem Reproduction/Confirmation: The range and charging problems have been repeatedly reproduced and confirmed by both dealership service departments and independent service centers during multiple service visits. The coolant system issue was also identified and addressed during these visits, indicating a persistent and recurring problem. Inspections: To date, the vehicle and its components have been inspected by dealership service departments on several occasions as part of the attempted repairs. There have been no specific inspections by the manufacturer, police, insurance representatives, or others outside of these service visits. Warning Lamps/Messages/Symptoms: Prior to the failure, there were instances of warning messages related to the vehicle's charging system and battery health. The first indications of these issues appeared shortly after purchase, escalating to the point of the vehicle being stranded due to insufficient charge. The coolant system issue was initially noted without specific warning lamps but was confirmed upon inspection during a service visit.
