Potential Consequences:
I am the owner of a 2024 Hyundai Ioniq 5 with Vehicle Identification Number [XXX] I purchased/leased this vehicle on [XXX] from Stockton Hyundai. Over the last couple of months my vehicle has experienced an ongoing charging defect: it only charges on Level 1 but fails to charge properly using Level 2 or DC fast chargers, which significantly impairs its use, value, and convenience — a key feature advertised for this vehicle. The issue has not been confirmed by the dealer as they have not been able to figure out why it’s happening and the vehicle has not been inspected by anyone else I also feel like it’s a safety risk because I’m at risk of being stranded.

Defect Description:
ELECTRICAL SYSTEM
Potential Consequences:
The car was down to 16% charge on the battery so I put it on the 220 v charger at my house. The next day I went to leave and removed the charger from the car and started it. I heard a pop and thought the garbage truck doing weekly pickup had run over something but now I think it was a noise from the failed component. Got in the car and started it and saw a yellow circle with the words “check electrical system”; I had seen this error message once before following a software update to the ICCU back in September 2024 [turned the car off and back on and the error went away] so I did the same thing again but the error didn’t go away instead the circle warning on the screen went to a red circle and read “stop the car and check the electrical system”. Went inside the house and called the closest Hyundai dealership [in Longmont since the one in Boulder closed with no warning] and after some back and forth they told me to have the car towed in since the 12 v battery charging system wasn’t working and it controls many things like power steering and regeneration braking and can cause a loss of power making the car undriveable and unsafe. Towed the car in and got a diagnosis of a failed ICCU module. The part is on order and I have no idea when it might actually come in and get installed. Hyundai is aware of problems with the ICCU and 12 v charging system and has issued several software recalls; this ICCU problem is all over the Hyundai Ioniq 5 forums and is a widespread issue with the Ioniq 5. I’m lucky this failure occurred at my home versus when I was driving or many miles away or at night cuz I would have been stranded.

ELECTRICAL SYSTEM
Potential Consequences:
On 4/7/2025 the vehicle came to a dead stop while driving about 45 mph on a highway entrance. I was able to get the car to the edge of the highway but it was completely inoperable. It required towing to the nearest dealer. After a day diagnosis it was determined that the ICCU and 12 volt battery had failed. I was stranded on the edge of the highway while waiting for a tow. The problem was confirmed by the dealer, replacement parts were ordered and the repair completed seven weeks later. A warning message appeared so briefly that I could not read it before the car failed completely.

ELECTRICAL SYSTEM
Potential Consequences:
The car made a loud popping noise and immediately started displaying electrical system fault errors. The car propulsion stopped within 15 seconds and was not able to be moved after. I was on the freeway and just barely made it over to the side. Car was not able to be towed by a regular tow truck because the electrical system was gone and the car was not able to be shifted into neutral. Jump starting the battery did nothing. Car was sent to the dealer who confirmed that the car sustained an ICCU failure which controls the entire battery electric system. The ICCU had to be replaced. There is already a mandatory recall on the vehicle regarding the ICCU. The recall was to check the status and confirm that the ICCU was working properly and in good condition. I had this recall done BEFORE the ICCU failed, so even though the recall check was performed, the ICCU still failed and put me in a very dangerous situation. The car is 6 months old and has 6200 miles on the odometer.

ELECTRICAL SYSTEM
Potential Consequences:
Dear NHTSA, On [XXX] at [XXX] CST, my 2024 Hyundai Ioniq 5 SEL experienced a sudden ICCU failure. While reversing into my driveway, I heard a loud “pop,” followed by warning messages: “Stop vehicle and check power supply” and “Check electric vehicle system.” A DTC scan showed code P1A90(96). The car became inoperable and had to be towed to a Hyundai dealership. The dealer confirmed ICCU failure and replaced both the ICCU and fuse on 6/17/2025. However, the replacement was not a redesigned part—it was the same model that failed. I purchased this vehicle in March 2025 as a Certified Pre-Owned with ~12,000 miles. All recall-related ICCU updates had been completed before this incident. There were no warning signs before the failure. This failure could have been dangerous had it occurred on a highway, in extreme weather, or far from help with my [XXX] daughter with me. I no longer feel safe driving this car. Hyundai’s recall remedy is clearly not effective, and they continue replacing defective ICCUs with the same flawed units. They have not disclosed the root cause or implemented a permanent fix. I urge NHTSA to: Investigate ongoing ICCU failures despite recall compliance. Mandate a stop-sale of affected vehicles until a real fix is found. Require Hyundai to disclose the root cause. Consider a buyback program if no safe solution is available. This is a serious safety risk. These failures will continue without regulatory action. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I urge NHTSA to: Investigate ongoing ICCU failures despite recall compliance. Mandate a stop-sale of affected vehicles until a real fix is found. Require Hyundai to disclose the root cause. Consider a buyback program if no safe solution is available. This is a serious safety risk. These failures will continue without regulatory action. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

POWER TRAIN
Potential Consequences:
Dear NHTSA, On [XXX] at [XXX] CST, my 2024 Hyundai Ioniq 5 SEL experienced a sudden ICCU failure. While reversing into my driveway, I heard a loud “pop,” followed by warning messages: “Stop vehicle and check power supply” and “Check electric vehicle system.” A DTC scan showed code P1A90(96). The car became inoperable and had to be towed to a Hyundai dealership. The dealer confirmed ICCU failure and replaced both the ICCU and fuse on 6/17/2025. However, the replacement was not a redesigned part—it was the same model that failed. I purchased this vehicle in March 2025 as a Certified Pre-Owned with ~12,000 miles. All recall-related ICCU updates had been completed before this incident. There were no warning signs before the failure. This failure could have been dangerous had it occurred on a highway, in extreme weather, or far from help with my [XXX] daughter with me. I no longer feel safe driving this car. Hyundai’s recall remedy is clearly not effective, and they continue replacing defective ICCUs with the same flawed units. They have not disclosed the root cause or implemented a permanent fix. I urge NHTSA to: Investigate ongoing ICCU failures despite recall compliance. Mandate a stop-sale of affected vehicles until a real fix is found. Require Hyundai to disclose the root cause. Consider a buyback program if no safe solution is available. This is a serious safety risk. These failures will continue without regulatory action.

ELECTRICAL SYSTEM
Potential Consequences:
I was driving on a highway during traffic on June 17 2025 and my ioniq 5 car started to make weird sound. Then after a minute, it abruptly started to push back and forth and the noise became stronger. A couple of minutes later, the "Check electrical vehicle system" sign was displayed on the screen. I pulled over due to the scare and turned off the car. A minute later, turned ON the car and drove. Same exact thing happened a day before too. This has not happened before since I got the car in Dec 2024. Car's battery was at 82%.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
Potential Consequences:
While backing into my driveway if a car passes in front on the street my car will not continue backing up. This also happens in parking lots. While backing out of my driveway onto the street and staying in the lane closest to the driveway, traffic in the far lane will cause the car to stop moving even though the street is more than wide enough to accommodate both cars without crossing the double yellow lines. As I live on a busy street this can cause an accident. In both cases turning off the parkin sensors with the dashboard button has no effect.
