What is the 2025 Kia EV6 Pre-Charge Resistor Damage From PDC Software Logic Error — Vehicle Will Not Enter READY, DTC P1B7700 (Campaign SC343)?
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.
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 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 Third-Party Kia Connect Integrations May Contribute to 12V Battery Drain (Kia PS748)?
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.
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 2022-2025 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 2022-2025 Kia EV6 Forward Collision-Avoidance Assist (FCA) Phantom Braking / False Warnings?

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 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.

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 2022-2025 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.
