5/5 Overall
NHTSA 5-Star Safety Rating
Electrical system complaints dominate what 2025 Ioniq 6 owners report, making up the largest share of filed complaints for this model year. The most frequently described pattern involves sudden loss of power while driving, often accompanied by a "12-Volt System Deactivated" warning on the display. Owners describe the vehicle slowing unexpectedly, sometimes at highway speeds, with several tracing the issue to a failed integrated charging control unit or 12-volt battery. A smaller number of powertrain and propulsion complaints overlap with this theme, as owners report the car behaving as though it's about to stall mid-drive. Outside the power-loss cluster, a couple of isolated reports describe windshield cracking when the defroster is used in cold weather, and one report describes unexpected acceleration at low speed.
