This page covers 5 recalls, 129 owner complaints and NHTSA crash-test ratings for the 2023 Kia Ev6.
5/5 Overall
NHTSA 5-Star Safety Rating
Electrical system complaints dominate owner reports for the 2023 KIA EV6, accounting for roughly half of all filed complaints. The most frequently described issue centers on the integrated charging control unit (ICCU), which owners report failing without warning. Common symptoms include a "Check Electrical System" warning on the instrument cluster, the 12-volt battery dropping voltage, and the vehicle progressively limiting speed, sometimes down to 30 mph, before becoming undriveable. Several owners describe being stranded and requiring a tow. Powertrain and propulsion complaints follow at lower volume, with owners describing sudden power reduction, turtle mode activation, and error messages appearing together, occasionally accompanied by a burning smell from the drivetrain. Some owners report that dealer repairs, including 12-volt battery replacement and software updates, did not fully resolve the underlying electrical fault on the first service visit.

By System
The 2023 KIA EV6 has 5 recalls, the most serious being a high-voltage battery cell defect where misaligned electrodes can cause the vehicle to catch fire while parked or in motion.
The remaining recalls share a common theme: loss of drive power. A rear axle shaft can break under load, cutting power to the wheels without warning and leaving the vehicle unable to accelerate or maintain speed. Prior repair attempts did not fully resolve this issue, and a separate filing covers the same driveshaft failure from a different angle, so owners should confirm with a dealer whether their specific vehicle has received a complete remedy. On the electrical side, the integrated charging control unit can fail and stop replenishing the 12-volt battery. In an electric vehicle, that auxiliary battery handles critical systems including the drive computers, so when it drains completely the car can lose drive power entirely. This charging unit issue was addressed in two separate campaigns, one involving a hardware remedy and one involving a software update, and both may apply to the same vehicle.
