2024 Hyundai Ioniq 5 Complaints

The contact owns a 2024 Hyundai Ioniq 5. The contact stated while driving at an undisclosed speed, the vehicle stalled and failed to return to normal operation. The "check the battery" message was displayed on the instrument panel. The vehicle was towed back to the residence. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 9,240.

I was driving and the vehicle was operating as expected in normal conditions when I heard a loud pop sound, followed by an alert on my car infotainment to pull over and inspect the 12v battery. "12 volt battery low. Stop safely" I turned the car around to drive back home. The car wouldn't go any faster than 40mph. Once parking the car back home, the car would not turn on anymore. This is congruent with what I've been reading online about other Hyundai Ioniq 5 drivers experiencing when the ICCU in the car fails, requiring Hyundai to fix it.

There was a failure of the ICCU (Integrated Charging Control Unit) on my Ioniq 5 that forced me to pull off the highway after my car was no longer able to accelerate past 40 or so MPH.

I lease a 2024 Hyundai Ioniq 5 AWD. Prior to a planned trip, the vehicle displayed an electrical system warning. I contacted the dealership and was advised to bring it in. While driving approximately 5 miles to the dealership, the vehicle lost all power including hazard lights, leaving me stranded on a busy road. I contacted roadside assistance and the vehicle was towed to the dealership. The dealership confirmed the failure was caused by the ICCU (Integrated Charging Control Unit). The repair took approximately two weeks. The vehicle was unavailable during this time, requiring a rental car. Hyundai partially reimbursed rental costs but did not compensate for other losses incurred. The ICCU failure is a known widespread issue affecting the entire Hyundai/Kia E-GMP platform across multiple models and model years.
