According to Au7o's analysis of 846+ owner reports, the 2025 Kia EV6 has 3 documented known issues. No issues are rated critical, indicating generally reliable ownership. The most commonly reported issue is Heat Pump Malfunction in Cold Weather with 423 owner reports. Across all issues, repair costs range from $0 to $4,000. DIY maintenance guides at au7o.io.
On the 2022-2025 Kia EV6, 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 compressor can also produce loud clicking or knocking sounds during cold starts. Software updates have improved low-temperature heat pump operation.
Have dealer perform latest HVAC software update to improve cold-weather heat pump operation. Pre-condition the cabin while plugged in to reduce cold-start heat pump strain. Some owners add aftermarket heated seat cushions for supplemental heating. If heat pump compressor has failed, replacement under warranty ($1,000-2,000 part).
Parts and tips from 423+ owners who fixed this issue
On the 2022-2025 Kia EV6, 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 must open fully. The issue occurs more frequently in cold weather when the actuator motor draws more current.
Emergency override: there is a manual release cord in the front trunk area to open the charge port door. Charge port door actuator replacement ($200-400 part, 1 hour labor). Applying silicone lubricant to the latch mechanism preventively can reduce cold-weather failures. Under basic warranty (5 years/60,000 miles).

On the 2022-2025 Kia EV6, 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 motor continues to function. Kia has replaced rear motors under warranty for some owners.
Have dealer diagnose with an EV-specific vibration analyzer to confirm motor bearing noise versus normal operation. Under EV powertrain warranty (10 years/100,000 miles), the rear motor assembly is replaced if bearing wear is confirmed. Out-of-warranty motor replacement: $2,000-4,000.
