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.

STRUCTURE:BODY
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)

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
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.

March 21st at around 7:30 PM, I was driving on the highway when my panoramic sunroof suddenly exploded—or shattered—completely out of nowhere. It was a clear night, no rain or debris, and there were no cars directly in front of me. Nothing hit it—no rocks, no objects—just a loud bang, and the glass was gone. I’ve got photos of the damage (attached), and it’s clear this wasn’t caused by an external impact. The glass blew outward, which makes me think it’s a manufacturing defect or stress in the material. Thankfully, no one was hurt, but this is a major safety issue.

There are 2 horns; a high tone and a low tone. The low tone horn failed, making the horn sound difficult to hear. This same issue has been reported by many Ioniq 6 owners. I scheduled an appt w/ a Hyundai dealer and the defective horn was replaced. This happened when the vehicle had less than 3,000 miles.

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.

The ioniq 6 horn is a two (2) tone horn. First, one (1) of the tones went out (lower tone). Now, the horn completely doesn't work. Reading online, this is a common issue with the 2023 & 2024 ioniq 6. This is the same horn (car is the same platform) as the ioniq 5, and lots of forums online also have people posting about their horns going out and not working at all.

While driving, "check power system" warning appeared on this 2023 Hyundai Ioniq 6. Moments later an alarm sounded advising to stop driving and turn off engine. I was able to drive to a safe place although the vehicle would not accelerate beyond approximately 15 mph. Car was conveyed by carrier truck to dealer where as of this date it has remained for two weeks as the service department awaits parts. Note: all prior software updates/recalls had been completed before this unfortunate incident occurred.
