5/5 Overall
NHTSA 5-Star Safety Rating
Electrical system complaints dominate what 2023 Ioniq 6 owners report, making up roughly half of all filed complaints. The most frequently described issue centers on the integrated charging control unit (ICCU), where owners report the vehicle entering a reduced-power "turtle mode," cutting speed to well under 30 mph, and displaying a "Check Electrical System" warning. Several owners report the ICCU failing more than once, with the vehicle returning to the dealer for the same fault after a prior repair. A related pattern involves the 12-volt battery draining as a consequence of the ICCU fault, leaving the car unable to restart without a jump. Some owners also describe sudden, complete power and steering loss while driving, with no warning lights preceding the event. Engine and powertrain complaints trail far behind at four reports each, with no clear pattern emerging at that volume. The ICCU and associated electrical failures account for the bulk of what owners are reporting.

By System
The 2023 Hyundai Ioniq 6 has 7 recalls, the most serious involving the rear driveshaft, which can break under load and cut drive power to the wheels, raising the risk of a crash.
The charging control unit (ICCU) is the subject of another significant recall: the unit can fail and stop charging the 12-volt battery, which also causes a loss of drive power while the vehicle is in motion. Prior repair attempts did not fully resolve this issue, and a software update has since been issued as part of the remedy. On the occupant safety side, the driver and passenger seatbelt anchors can detach, leaving occupants without adequate restraint in a crash. There are also two lower-severity issues related to the charging port door panel, which can loosen and fall off the vehicle, creating a hazard for other drivers on the road.
