The ICCU on my 2023 Hyundai Ioniq 6 failed on December 5, 2025 after 19,616 miles. Luckily, the car was parked in my driveway when this occurred. If the car was in motion when the ICCU failure occurred it would have been very dangerous. The car cannot be driven. The car's system shows Hyundai Diagnostic Trouble Code (DTC) P1A906. The problem has been confirmed by a dealer. A new ICCU has been ordered. The car is under warranty and the dealer provided a loaner car while my car is being repaired.

Subject: Safety Complaint – Sharp Upper Door Edge Causing Facial Injury (Hyundai IONIQ 6, 2023) Message: To whom it may concern, I would like to submit a safety complaint regarding my 2023 Hyundai IONIQ 6 (VIN: [XXX] ). On October 14, 2024, my wife suffered a facial injury caused by an extremely sharp upper edge of the front door. This occurred in our driveway at [XXX] . The injury happened when the front door stopped at its mid-detent position and the sharp, exposed upper edge made forceful contact with her forehead and the area next to her eye. She avoided a direct eye injury only due to quick reflex. This design presents a serious risk to passengers, especially those of shorter stature. I have photographic documentation showing the sharp door edge and the injury mechanism. Hyundai Motor America was informed, but they dismissed the case and advised us simply to “be more careful.” They offered a $150 virtual compensation card, which I did not use, because accepting it could be interpreted as accepting their proposed settlement. Hyundai insisted on dealer inspection, which is irrelevant because this is not a defect of a single unit — all vehicles of this model have the same door-edge geometry. I believe this is a safety-related design hazard affecting all Hyundai IONIQ 6 vehicles. I respectfully request that NHTSA review this case, as the risk of eye or facial injury is significant. Please let me know if you require additional information or photographs. Sincerely, [XXX] [XXX] Phone [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Integrated charging control unit ICCU failed and was replaced by dealer. Warning light directed me to immediately pull over and have the car towed to the nearest dealer. Dealer confirmed ICCU failure with Diagnostic trouble code DTC P1A9096. Unknown whether the failed ICCU has been inspected by the manufacturer, police, insurance representatives or others.

I was crossing the Mackinac Bridge, northbound, this afternoon, at the time traveling over the bridge deck's grates in the left lane. Traffic was backed up and I was traveling in the single-digit MPH. There was more that a car's length between myself and the next car ahead, and as I accelerated a little bit to close the distance my emergency braking activated. Fortunately, the car behind me was trailing by a little bit and was also traveling slowly.

ICCU failure. EV car flashed battery issues and could not drive. ICCU and 12 volt battery replaced after 10 days in dealership shop. Manufacturer inspected. Prior to issue electric hatchback closed half way then stalled. I drove to the dealership and asked them to check if there was something wrong. They closed the hatch manually and said the 12 volt battery was fine and the computer said something blocked the closure, I left the dealership and made it less than a mile before battery light went off (within 5 minutes of leaving dealership). Made it back to dealership in turtle mode and this time computer said the ICCU failed.
