Kia Long Range AWD
Dual-motor all-wheel drive on the E-GMP platform with high system output. Convincing traction on all surfaces — check battery state of health with a diagnostic tool when buying used.
EV6 AWD — electric all-wheel thrill
325 hp all-wheel drive in the EV6 — 0-100 in 5.1 seconds and immediate response. Unusually good driving fun for a family EV.
Engine Weaknesses 4
Identical ICCU issue as on the RWD: the integrated charging control unit can fail and no longer supply the 12V network. Kia recalled EV6 AWD (2022–2024) under the same recall (SC327).
Symptoms: Audible 'pop' noise, dashboard warning lights, gradual loss of drive within 22–45 minutes
The AWD variant of the EV6 is fully affected by the ICCU recall. The combined load of both electric motors can increase the thermal stress on the ICCU unit.
Symptoms: Gradual power reduction, 12V system failure, vehicle comes to a standstill, no hazard flashers possible.
On performance-oriented AWD vehicles, bearing noise from the rear reducer has been reported, particularly with a spirited driving style and at higher mileage.
Symptoms: Humming from the rear axle area at certain speeds, increasing noise level at higher mileage.
As with the RWD variant, the heat pump on the AWD EV6 also generates loud whistling noises at low temperatures. Software updates resolve the issue on most affected vehicles.
Symptoms: Whistling or whirring from the climate area when heating is on below 0°C.
Vehicle Weaknesses 6
The integrated charge control unit (ICCU) charges the 12V starter battery incorrectly, which can cause the vehicle to stall. Recall for approx. 19,078 vehicles in Germany (production April 2021 to February 2024). Software update or ICCU replacement.
Even after the ICCU recall, EV6 drivers report a flat 12V battery after extended periods of inactivity. An infotainment system crash prevents a complete shutdown and drains the battery.
On the Kia EV6 CV, leaking expansion valves have been documented that cause complete AC failure. Refrigerant loss becomes apparent through lack of cooling and heating.
The EV6's infotainment system occasionally freezes or reboots. Known link to 12V battery problems. Kia provides regular OTA updates.
On the Kia EV6 CV, rumbling suspension noises occur at the front when the vehicle rolls on poor road surfaces. The cause is often loose suspension bolts or dust boots.
On the Kia EV6 CV, the headliner creaks in the area of the B-pillar above the driver's door, particularly when the body flexes on uneven surfaces. Multiple forum members report the same symptom.
