What is the 2022-2024 Kia EV6 ICCU Failure and 12V Battery Drain?
The Integrated Charging Control Unit (ICCU) in the 2022-2024 EV6 can malfunction and stop charging the 12V battery from the main high-voltage battery pack. This causes the 12V battery to drain, resulting in a no-start condition and loss of drive power. NHTSA recall covers affecte… Repairs typically run $0-$2,500. Severity: high.
What is the 2022-2023 Kia EV6 Brake Lights Fail to Illuminate During i-Pedal / One-Pedal Regenerative Deceleration (Campaign SC273A)?
On early EV6s, using strong regenerative braking (i-Pedal / one-pedal mode) can decelerate the car firmly — even to a full stop — without illuminating the brake lights, unless the driver fully lifts off the accelerator. Consumer Reports independently confirmed the 2022 EV6 Wind A… Repairs typically run $0-$0. Severity: high.
What is the 2022 Kia EV6 Shift-by-Wire Rollaway Risk in Park (SCU Software Defect)?
On 2022 EV6s, a voltage fluctuation in the Shifter Control Unit (SCU) while the vehicle is off and in Park can affect the command to the parking pawl actuator, temporarily disengaging the parking mechanism and allowing the car to roll away. NHTSA recall 22V322 covers 2022 EV6 uni… Severity: high.
What is the 2022-2025 Kia EV6 Electric A/C Compressor Failure and Long National Parts Backorder?
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.
What is the 2022-2025 Kia EV6 Heat Pump Malfunction in Cold Weather?
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.
What is the 2022-2025 Kia EV6 Charge Port Door Actuator Failure?
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.
What is the 2022-2025 Kia EV6 Rear Electric Motor Bearing Whine (AWD Models)?
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.
What is the 2022-2025 Kia EV6 Severe Highway Vibration from Loose Acoustic Foam Inside OE Tires?
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.
What is the 2022-2023 Kia EV6 Reduced DC Fast-Charging Speed in Cold Weather (Capped ~70 kW Without Preconditioning)?
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.
What is the 2022-2025 Kia EV6 Brake Rotor Corrosion and Pitting from Low Regen-Braking Use?
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.
What is the 2022-2025 Kia EV6 Premature Inner-Edge Rear Tire Wear from Negative Camber?
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.
What is the 2022-2023 Kia EV6 Level 2 AC Home Charging Interruptions from Charge-Handle Overheating (TSB ELE283 / ELE295)?
Distinct from the cold-weather DC fast-charge speed cap, many EV6 owners cannot reliably complete a Level 2 (240V AC) home charge. The onboard charging logic (VCMS) monitors the temperature of the charge connector/inlet, and when the handle warms up during a normal 40-48A session… Repairs typically run $0-$400. Severity: medium.
What is the 2022-2025 Kia EV6 Forward Collision-Avoidance Assist (FCA) Phantom Braking / False Warnings?
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.
What is the 2022-2025 Kia EV6 Spontaneous Windshield Cracking on Acoustic Laminated Glass?
EV6 owners widely report windshields cracking with little or no impact — a line appearing from the edge and spreading horizontally, or a crack forming during a car wash, after max defrost on a cold morning, or even while parked. The EV6 uses thin acoustic laminated glass (special… Repairs typically run $450-$1,500. Severity: medium.
What is the 2022-2025 Kia EV6 Infotainment Reboots and Apple CarPlay / Android Auto Disconnects?
EV6 owners widely report the head unit lagging, freezing, or rebooting (including after OTA updates) and dropping wired or wireless Apple CarPlay/Android Auto, with disconnects often recurring every 20-30 minutes. A loose/worn USB-data port and cable quality are commonly implicat… Severity: low.
What is the 2022-2024 Kia EV6 Meridian Premium Audio Defect — Out-of-Phase Subwoofer / Failing Amplifier?
EV6 trims with the 14-speaker Meridian system suffer audio defects: the subwoofer is wired out of phase with the other speakers (killing bass), and some amplifiers produce speakers that play at very low volume or no sound at all. A law firm opened a defect investigation, and Kia… Severity: low.
What is the 2022-2025 Kia EV6 Panoramic Roof / Sunroof Rattle and Creak (Temperature-Dependent)?
Owners, particularly of glass-roof / GT-Line and GT cars, report a hard-plastic rattle or creak from the roof/headliner area. The noise is present with the roof/sunshade closed and generally disappears when it is vented or opened, pointing to plastic frame components rattling or… Repairs typically run $150-$600. Severity: low.
What is the 2022-2025 Kia EV6 Flush Door Handles Freeze and Fail to Present/Open in Cold Weather?
The EV6's motorized flush 'presenting' door handles are prone to icing up in freezing/wet conditions. After a freeze, handles can fail to pop out (or fail to retract), and owners have reported being locked out or rear doors that would not open. Complaints appear at temperatures o… Repairs typically run $0-$200. Severity: low.
What is the 2022-2025 Kia EV6 Power Tailgate / Liftgate Intermittently Stops Working?
Owners report the power tailgate refusing to open or close automatically — sometimes reverting within 48 hours of a dealer reset. The powered gate uses pinch-strip obstruction sensors in the struts; an over-current in one motor (or the gate sticking to its wet weather-seal) makes… Repairs typically run $100-$800. Severity: low.
What is the 2022-2025 Kia EV6 Front Suspension Clunk / Knock Over Bumps (Sway-Bar Links and Strut Mounts)?
A frequent EV6 owner complaint is a distinct clunk or knock from the front end over sharp bumps, expansion joints, speed bumps, or at low speed. It is commonly traced to front stabilizer (sway) bar end links, strut top mounts, or bushings. The heavy E-GMP curb weight loads these… Repairs typically run $80-$450. Severity: low.
