   The Integrated Charging Control Unit (ICCU) has failed repeatedly on this vehicle. It has been replaced three times by Haselwood Hyundai dealer since the vehicle was purchased new in 2021. Dates: 9/8/2023, 12/19/2024, 9/30/2025 at approximately 17k, 35k, and 50k miles. Each failure presents the same way: the ICCU stops charging the 12V battery from the high-voltage pack, the 12V drains, and warning messages appear on the dash: Check Electric Vehicle System. The vehicle then…

   Finished charge, low battery indicator on the dashboard. started to drive, within mile "pull over immediatedly" well documented and continued flaw with vechile ICCU component (that I had the software "patches" applied). Car will no longer accept charge (so now has the remaining charge before being a 3 ton brick) and cannot not be driven as if the 12v battery loses charge (which it will) I will lose powersteering and brakes.

   On January 19, 2026, the vehicle lost power while driving and required a tow to the local dealership. After inspection, the dealership determined that the ICCU was at fault and needed to be replaced. The ICCU part was backordered. The vehicle was inoperable for 6 weeks as we waited for the part to be available and installed.

   The ICCU failed while 300 miles from home. I was unable to charge the car with level 2 charging to get home. Luckily level 3 charging still worked. The ICCU breaking can also disrupt propulsion, so I'm lucky it didn't break to that degree while driving. The dealership ultimately replaced my ICCU. There were no warning signs. In fact, the car didn't even throw a code or error. It simply wouldn't charge.
