Owner report 11700722 · 2025-11-21 (November 21, 2025)
The ICCU had a failure and fuse also blew; vehicle needs those parts replaced. After reading about ICCU recalls, my vehicle was not in the last recall. It affected 2023-2025 models I started up my car in morning and was about to reverse out of my driveway. I heard a pop near the rear of my vehicle and then saw a "Check Electric Vehicle System" warning and battery light indicator on my dashboard. I tried driving around for a couple of minutes around my area, the car would not accelerate over 20-25 mph. I returned home and looked up the issue. …

Owner report 11709790 · 2026-01-08 (January 8, 2026)
It is the ICCU (Integrated Charging Control Unit). The car lost power while I was going up a steep hill with a car behind me. The Hyundai dealership technician stated it is the ICCU (Integrated Charging Control Unit), and according to him, "We have ordered a replacement ICCU and FUSE. No eta on special order parts." The dashboard gave me the following message with a red battery symbol: “stop vehicle and check power supply.” In researching the VIN on the HYUNDAI SAFETY RECALLS AND SERVICE CAMPAIGNS website I learned that servicing was done on N…

Owner report 11719923 · 2026-02-23 (February 23, 2026)
My leased 2025 Hyundai Ioniq 6 experienced a sudden malfunction resulting in loss of vehicle operation. The vehicle has been at the dealership with delayed diagnosis and no clear repair timeline provided. This appears to be a safety-related defect involving the electric system. I am aware of multiple reports and recent news coverage describing similar failures in Hyundai/Kia electric vehicles related to ICCU (Integrated Charging Control Unit) defects, which can cause sudden battery discharge and loss of propulsion. Media reports indicate that…

Owner report 11733569 · 2026-04-24 (April 24, 2026)
I was driving at 60mph. I heard a sudden pop that felt like it came from behind me / under the car. While I glanced to see if I ran over something (I did not), the car suddenly felt like it was about to stall. It was slowing down quickly and dramatically. My safety was in danger as I quickly dropped speeds in heavy traffic on a freeway without warning. I was able to maintain control, and I turned my hazards on. I noticed that I was maintaining speed around 35-40 mph (no matter how heavy I hit the accelerator), and I moved to the right lane and…

NHTSA COMPLAINT , SHORT VERSION I am reporting a persistent, unresolved, safety-related steering defect in my 2025 Hyundai Ioniq 6 (leased 10/12/2024).

Owner report 11743155 · 2026-06-10 (June 10, 2026)
"While driving a 2025 Hyundai Ioniq 6 at approximately 10,000 miles, the vehicle experienced a sudden, catastrophic Integrated Charging Control Unit (ICCU) failure with no advance warning. The vehicle instantly experienced a total electrical shutdown while the car was on the ramp. The failure completely bypassed and disabled standard safety redundancies: the electronic parking brake/emergency brake system failed , and the 12-volt backup battery died instantly, making it impossible to activate the hazard lights. The vehicle became a completely i…
