ICCU failure and power loss
6,255–14,794 miles
NHTSA complaints for the 2025 Hyundai Ioniq 6, grouped by the part owners named. Open a row to read what goes wrong.
Sudden loss of power is the dominant problem. Drivers often hear a pop, then get a "Check Electric Vehicle System" warning. Speed drops to a crawl or the car shuts down completely, sometimes on freeways or at night in winter weather. The 12-volt battery stops charging. Dealers usually diagnose a failed ICCU (Integrated Charging Control Unit), often with a blown fuse. Replacement parts are frequently backordered, so cars sit at dealers for weeks. Failures show up early, around 10k to 14,794 miles. One crash report describes the car surging forward at low speed in a driveway.
The ICCU and the high-voltage fuse fail without warning, and the car goes straight into limp mode. Top speed falls to somewhere between 11 and 25 mph while traffic around it is moving fast. In at least one case every system except the blinkers quits, leaving the car stuck in the road in freezing weather. Dealers fix it under warranty by fitting the same part again, and replacement units can be backordered. One failure came at 6,255 miles.
A "check electrical system" warning comes on and the car goes into limp mode, capped at 20 mph. A few miles later it loses all power and has to be towed. The dealer reads code DTC P1A9096, which points to ICCU failure. A separate report says the high-voltage battery still will not charge to full capacity after the ICCU was replaced.
The windshield cracks when the defroster runs on a cold morning. A separate report describes a windshield scratched by the wipers on a car only months old, which causes glare when driving into the sun. The manufacturer suggested debris on the wipers was to blame and did not accept responsibility. Neither report involves a crash or a loss of control.
