Safety concerns are highlighted as vehicles have stalled in intersections or on highways, posing risks due to the inability to shift to neutral or activate emergency flashers. These patterns and symptoms suggest potential reliability concerns for used car buyers considering this model.
POWER TRAIN
17 complaintsOwners report that the 2023 Kia EV6 frequently experiences sudden and complete power failures linked to the Integrated Charging Control Unit (ICCU), often without warning. Complaints frequently mention symptoms such as the vehicle entering limp mode, a loud popping sound, and total loss of propulsion, sometimes accompanied by dashboard warnings like "Check electric vehicle system." These issues appear at various mileages, with some occurring as early as 8,000 miles. Safety implications are significant, as the loss of power can leave drivers stranded in traffic or on highways, posing a risk of collision. Buyers considering a used 2023 Kia EV6 should be aware of these recurring power train issues and their potential impact on vehicle safety and reliability.
UNKNOWN OR OTHER
5 complaintsOwners of the 2023 Kia EV6 frequently report issues related to charging and power loss. Complaints describe the vehicle not charging at its rated capacity on level 2 chargers, with the charging port becoming extremely hot, potentially posing a fire risk. Multiple owners also mention a loss of motive power while driving, particularly at highway speeds, which increases the risk of crashes. These issues often occur within the first two years of ownership and at mileage under 24,000. Additionally, some owners face challenges with dealership service, including delays in resolving these issues and lack of available parts. Safety concerns are heightened by the potential for sudden power loss and overheating during charging.
FUEL/PROPULSION SYSTEM (4 complaints)
FUEL/PROPULSION SYSTEM
4 complaintsSafety-relatedOwners report issues with the 2023 Kia EV6's fuel/propulsion system, including sudden loss of power and propulsion, often without prior warning. Complaints frequently mention warning lights for the electric vehicle system and power supply, leading to the vehicle entering reduced speed mode or shutting down completely. Two incidents involve crashes, one during lane changing on a freeway due to motor disablement, and another while parking when unintended acceleration occurred. Additionally, battery pack issues result in low range and range anxiety, with one owner stranded for hours in cold weather. These problems occur at various mileage levels and are sometimes linked to weather conditions, with service interventions not significantly improving performance.
SERVICE BRAKES (4 complaints)
SERVICE BRAKES
4 complaintsOwners of the 2023 Kia EV6 report several braking issues, with two main patterns emerging. Firstly, multiple complaints describe the i-Pedal feature, intended for one-pedal driving, failing to stay engaged, forcing drivers to switch abruptly to traditional brakes, which increases the risk of delayed reactions in traffic. Secondly, some owners experience unexpected brake behavior, such as rear tires locking up during normal braking or the vehicle stopping abruptly without driver input, often accompanied by a grinding noise and vibrations. These issues typically occur without warning lights or error messages, and some reports suggest they persist even after dealer inspections. Safety implications include potential loss of control and increased risk of accidents, especially when the brake lights do not illuminate during rapid deceleration in i-Pedal mode.
TIRES (3 complaints)
TIRES
3 complaintsOwners of the 2023 Kia EV6 report issues with tires, particularly involving unexpected deflation and handling difficulties. One owner describes an instantaneous deflation of a rear tire at highway speeds, despite proper tire pressure and good road conditions, suggesting potential product defects. Another complaint involves a tire vibration issue due to a separated foam tire liner, which was resolved by removal, but raises concerns about potential recurrence. These issues are reported at approximately 11,556 miles, and there are safety implications such as difficulty in vehicle control and potential hazards if similar problems occur in other tires. Buyers should be aware of these tire-related concerns when considering this vehicle.
ENGINE (3 complaints)
ENGINE
3 complaintsOwners report issues with the 2023 Kia EV6's cooling system and charging system. Complaints frequently mention coolant leaks or malfunctions, leading to repeated coolant refills within a short timeframe, such as three times in 49 days. Additionally, there are reports of significant charging system failures and battery management issues, resulting in range discrepancies and potential stranding. Symptoms include warning messages related to charging and battery health, while coolant issues often lack warning lamps but are identified through physical checks. Safety implications arise from the risk of engine overheating and being stranded in unsafe locations, with problems emerging shortly after purchase.
VISIBILITY/WIPER (1 complaints)
VISIBILITY/WIPER
1 complaintA small amount of snow / ice is sufficient to prevent the windshield wipers from returning all the way to the original starting position low on the windshield. For some reason this prevents them from functioning entirely - they just get stuck in a loop trying to go all the way down. I am able to lift them up manually but they won't do so under wiper motor power / while driving. I have a video that clearly shows the failure mechanics that this system won't allow me to upload.
STEERING (1 complaints)
STEERING
1 complaintMy 2023 Kia EV6 experienced a sudden ICCU and 12-volt system failure while traveling approximately 50 mph. Without warning, the vehicle instantly lost propulsion and all electrical power. This included loss of steering assist, braking assist, hazard lights, shift capability (unable to shift into Park), and even the ability to lock the doors. The failure effectively “bricked” the vehicle in motion. I was only able to get the vehicle off the roadway because the road happened to slope downward into a nearby lot. Steering required significant physical effort, the brake pedal went completely hard (“dead”), and the vehicle offered no functional parking brake or Park engagement once stopped. Because I was on a hill, we had to allow the car to roll to the bottom until it met a curb to prevent movement. After power loss, the doors could not be locked at all. This type of unrecoverable electrical failure creates an extreme safety hazard for the driver, passengers, and surrounding traffic. There is no pre-warning and no diagnostic indicator. The ICCU fuse appears to fail spontaneously and renders the vehicle uncontrollable in several critical respects. This is not an isolated issue. ICCU failures have been occurring across the Kia EV6 and Hyundai Ioniq 5/6 platforms for more than three years, including on brand-new 2025 models. The persistence of this defect across multiple model years indicates that the underlying design or component defect has not been resolved by the manufacturer. Given the suddenness of the failure, the total loss of vehicle control systems, and the long history of similar incidents reported by other owners, I am now hesitant to drive the vehicle due to the unpredictable and dangerous nature of the defect.
STRUCTURE (1 complaints)
STRUCTURE
1 complaintThe trunk continues to rattle after multiple trips to the dealership, it has been verified to not be the license plate or any loose components by the dealership. The noise sounds like the trunk latch striking repeatedly during regular driving. The sister model Hyundai Ioniq-5 has had numerous TSBs to fix this issue while Kia EV6 has had none published. And example of the TSB listed is [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

How We Calculate Reliability Scores
Auto Reliability Index scores are calculated on a 0–100 scale using a weighted formula that combines multiple public data sources. Each factor is weighted based on its predictive value for real-world ownership experience.
Key Ranking Factors
Complaint Severity
NHTSA owner complaints weighted by component category (e.g., powertrain, safety systems, electronics, cosmetic) — safety-critical issues carry more weight than cosmetic ones. Adjusted for sales volume so high-volume models aren't unfairly penalized.
Repair Costs
Independent reliability ratings based on repair frequency, average repair costs, and severity of typical repairs for each model.
Recall Impact
Number of NHTSA recalls weighted by severity. “Stop driving” and fire-risk recalls are penalized more heavily than minor software or labeling recalls.
Issue Diversity
Measures how many major vehicle systems (engine, transmission, electrical, braking, etc.) have recorded complaints. A vehicle with issues spread across many systems may indicate systemic quality issues.
Scores are grouped into four tiers:
- 80–100: Excellent— Top-tier reliability, minimal issues
- 60–79: Good— Reliable with some minor concerns
- 40–59: Mixed— Notable issues, research before buying
- 0–39: Risky— Significant problems, proceed with caution
Data is sourced from NHTSA recall records, owner complaint filings, and independent repair databases. Scores are recalculated as new data becomes available. While the weighting model is proprietary, all underlying data sources are public and traceable.
