Our known issues database covers the 2022-2025 Kia EV6 with 29 documented issues documented across 846+ owner reports.
NHTSA campaign 24V867000 (Kia SC327) covers all 2022-2023 and certain 2024 EV6 vehicles. Transient high voltage and thermal cycling can damage the Integrated Charging Control Unit, preventing it from charging the 12-volt battery. Continued driving after warnings may cause progres… Severity: high.
Kia bulletins ELE283 and ELE295 address interrupted or inoperable high-voltage-battery charging caused by excessive temperature at the EV6 combo-charger inlet. Kia later opened voluntary campaign SC311 for certain EV6 vehicles that can experience interrupted Level 2 charging or r… Severity: high.
NHTSA campaign 24V057000 (Kia SC295) covers certain 2023 EV6 vehicles built from January 26 through April 8, 2023. A supplier manufacturing error may have left the rear inner drive shaft improperly heat-treated. The shaft can break under load, causing loss of motive power and inc… Severity: high.
In July 2026 Kia filed NHTSA recall 26V431 (Kia campaign SC375) for seven 2022-2024 EV6 vehicles built between December 30, 2021 and September 14, 2023 (plus one 2024 EV9). Supplier SK On produced certain battery cells with a misaligned electrode during limited production periods… Repairs typically run $0-$0. Severity: high.
Kia recall 24V867 (SC327) addresses ICCU damage from thermal cycling and transient high voltage. Loss of 12V charging can lead to warning messages and progressively reduced propulsion, potentially ending in loss of drive power and increased crash risk. The November 2024 filing co… Severity: high.
Kia SC343 concerns certain US-built 2025 EV6 (CV1a) vehicles produced December 10, 2024–June 24, 2025. A PDC software error can damage the pre-charge resistor during an abnormal shutdown, such as powering off in Neutral. Kia's owner letter describes a Service warning, Check elect… Repairs typically run $0-$0. Severity: high.
NHTSA campaign 22V322000 (Kia SC236) covers certain 2022 EV6 vehicles built from November 17, 2021 through April 7, 2022. A voltage fluctuation while the vehicle is off and parked can affect the Shifter Control Unit command to the parking-pawl actuator, temporarily disengaging th… Severity: high.
Kia voluntary service campaign SC273 applies to certain 2022-2023 EV6 vehicles other than the GT. During rapid regenerative deceleration in i-Pedal mode, the original Vehicle Control Unit logic may not illuminate the brake lamps unless the accelerator is fully released, reducing… Severity: high.
Owners report the EV6's high-voltage electric A/C compressor failing outright — sometimes taking cabin heat (heat-pump) with it since the same refrigerant loop is shared. Symptoms range from no cold air in hot weather (compressor won't stay energized above ~105°F) to stored 'ECOM… Repairs typically run $1,200-$2,600. Severity: high.
The EV6 heat pump HVAC system can malfunction in extreme cold weather (below 15F / -10C), failing to provide adequate cabin heating and causing the system to fall back to resistive heating. This dramatically reduces range in cold weather (up to 40-50% range loss). The heat pump c… Repairs typically run $0-$2,000. Severity: medium.
The EV6 charge port door actuator can fail, preventing the charge port door from opening or closing properly. The electric actuator motor burns out or the latch mechanism jams, leaving owners unable to charge. This is particularly problematic at DC fast chargers where the door mu… Repairs typically run $200-$500. Severity: medium.
AWD EV6 models can develop a noticeable whining or humming noise from the rear electric motor, particularly during deceleration and regenerative braking. The rear motor bearings develop wear and produce an audible whine that increases with speed. While the noise is annoying, the… Repairs typically run $0-$4,000. Severity: medium.
Kia's voluntary service campaign SC345 (August 2025) covers 2023-2024 EV6 built December 14, 2022 through February 22, 2024 whose front motor and reduction-gear assembly may have been filled with gear oil below factory specification during production. The front drive unit only ex… Repairs typically run $0-$0. Severity: medium.
Because the EV6 relies heavily on regenerative braking (i-Pedal/one-pedal), the friction brakes are used so little that the cast-iron rotors do not self-clean and develop surface rust that progresses to pitting. The resulting disc-thickness variation produces brake pulsation; EV6… Severity: medium.
Early EV6s (especially 2022 before the software update) suffer dramatically reduced DC fast-charging speed in cold weather — sessions can be capped around 70 kW instead of the advertised 230-240 kW peak when the 77.4 kWh pack is below roughly 15°C. Because early cars had no autom… Repairs typically run $0-$0. Severity: medium.
Kia bulletin PS748 (June 2023, all EV models from 2015) reports unexpected 12V battery drain and identifies excessive Kia Connect connections from third-party applications as a possible cause under investigation. Kia asks dealers to document affected customers' integrations in a… Severity: medium.
On 2022-2023 EV6 built November 17, 2021 through February 3, 2023 the Battery Management System lumped many pack faults under a single code, P1AA600: cell over-voltage deviation, insulation breakdown, abnormal cell-voltage movement after charging, abnormal current change during c… Repairs typically run $0-$0. Severity: medium.
A very commonly reported EV6 complaint is a strong steering-wheel and body vibration/shudder at highway speed, typically emerging around 58-70 mph, that returns even after repeated wheel balancing. The frequent root cause is not a bent wheel or bad balance but the sound-deadening… Repairs typically run $50-$400. Severity: medium.
The EV6's rear suspension runs aggressive negative camber, and combined with vehicle weight and instant torque, owners report rapid inner-edge wear on the rear tires — in extreme cases cords showing on a 2023 EV6 GT within a few thousand km. Excessive rear toe-out is also implica… Severity: medium.
EV6 owners report the Forward Collision-Avoidance Assist system triggering unwarranted alerts and hard automatic braking ('phantom braking') at speed with no real obstacle — on curved roads it may detect vehicles/objects in adjacent lanes, and a camera/radar sensor fouled by snow… Repairs typically run $0-$300. Severity: medium.
