2023 Hyundai Ioniq 6

Left the house, made it a few miles from the house. Loud pop from the rear seat, warning lights came up on the dash limited power and check electrical system. Was limited to 25mph to drive home. All recalls were done prior to failure. Last recall was done approx 2 weeks prior to failure. ICCU was diagnosed as the failure and was replaced.

The Integrated Charging Control Unit (ICCU) failed in November 2024. Instrument panel warning indicated an electrical failure and that the vehicle should be stopped immediately. The Hyundai dealer identified Diagnostic Trouble Code (DTC) P1A9096 and per Service Campaign 997 Technical Service Bulletin 23-01-060H replaced the Integrated Charging Control Unit (ICCU). In December 2024 Recall 272 TSB 24-01-086H software upgrade installed to further address Integrated Charging Control Unit (ICCU) failure.

The horn on my vehicle is defective after 16000 miles. I am available to take it in for an inspection. I was almost backed into and I had no way of alerting the other driver. This problem has not been reproduced by my local dealership but it has been at other national and international dealerships per forums. I am unsure if this component has been inspected by the manufacturer, police, insurance company, etc. This problem was random without warning which makes this even more of a safety concern since I had no clue this was defective until I actually had to use it.

Shortly after the ICCU recall was repaired I received numerous electrical system warnings on my Hyundai Ioniq 6 (2023, SE model). The dealership identified the problem to be the Battery Management System needed a complete replacement would you take 1-2 weeks. When you factor in three different ICCU service appointments (two SW updates and full replacement) the BMS issue was the fourth electrical / battery issue in the 16 months I've owned the vehicle. Purchased Sept 20, 2023 and have 40k miles.

4 days after having recall 272 performed by the dealer the ICCU on the vehicle failed. Warning lights indicated failure and to stop the vehicle. Luckily, only 1 mile from home and drove it home under reduced power . Called the dealer (70 miles away) and was told to tow the car to them. Car was diagnosed with ICC failure. Replacement had to be ordered but might take at least 4 weeks.

The dashboard error code (check vehicle power supply) also in the bluelink app the error code(DTC P1A9096). I was driving the car. It was 196 miles of range. The car suddenly went into turtle mode and then the car just died in the middle of the road. Luckily I was outside my residence. After waiting 4 hour for towing. I had it towed to the dealership.
