5/5 Overall
NHTSA 5-Star Safety Rating
Electrical system complaints dominate owner reports for the 2024 Ioniq 6, with the propulsion system and powertrain also drawing notable feedback. The most common pattern owners describe involves sudden, unexpected power loss while driving, vehicles abruptly drop from highway or normal driving speeds to 10–25 mph with no warning, often triggering a "check electrical system" warning on the dash. Several owners specifically describe the integrated charging control unit (ICCU) as the confirmed fault, with symptoms including complete vehicle shutdown, inability to start, and a dead 12-volt battery. Cold weather appears in multiple reports as a condition when these electrical failures surface. A smaller cluster of complaints involves the propulsion system behaving unexpectedly during low-speed maneuvering. One isolated report describes loose rear suspension alignment hardware that a technician attributed to the factory build.

By System
The 2024 Hyundai Ioniq 6 has 5 recalls, the most serious involving drivetrain failures that can cut power while driving or cause the differential to lock up, either of which raises the risk of a crash.
On the drivetrain side, differential gear bolts inside the gear drive unit may not be properly tightened, which can cause the vehicle to lose drive power entirely or, in a different failure mode, cause the differential to seize and lock the wheels. Separately but with the same consequence, the integrated charging control unit can fail and stop replenishing the 12-volt battery; when that battery drains, the vehicle loses drive power as well. Prior repair attempts did not fully resolve this charging control unit issue, which is why it appears in more than one campaign.
The seatbelt recall covers the front seat belt anchors for both the driver and passenger, which can detach from their mounting points. A detached anchor means the belt cannot hold an occupant back in a crash, significantly reducing restraint protection.
Finally, the charging port door panel on the driver's side can come loose and fall off the vehicle. A piece of body trim dropping onto the road at highway speed becomes a hazard for drivers behind.
