ELECTRICAL SYSTEM

Second failure of the Integrated Charging Control Unit (ICCU) on this 2025 IONIQ 5. The ICCU stopped charging the 12-volt battery, leaving the vehicle unable to start. This is the second time the ICCU has failed and required replacement in approximately one year. The vehicle was towed to the dealer. ICCU failure can cause a loss of drive power while driving; this failure was discovered while parked. Earlier model years (2022-2024 IONIQ 5) are covered by recall 24V-868 for this same defect; this 2025 vehicle is outside that recall population and has now failed twice.

ELECTRICAL SYSTEM

On XXX, while driving my 2025 Hyundai Ioniq 5 on a local road, the vehicle suddenly lost power and would not accelerate beyond 40 MPH. There was no prior warning. I had not yet merged onto the expressway. Had this happened at highway speed, I would have been unable to keep up with traffic, which would have created a serious risk of a collision. I continued driving at reduced speed until I could safely pull into a gas station. Once stopped, the instrument cluster displayed "Stop vehicle and check power supply." About 10 minutes later, with the vehicle parked and still on, it displayed "Check 12V battery. Stop safely and engage parking brake." Roughly 10-15 minutes after that, the vehicle shut down completely and could not be restarted. The vehicle was towed to Gerald Hyundai in [XXX] on that day. On XXX, the dealer confirmed that the Integrated Charging Control Unit (ICCU) and a fuse failed and had to be ordered for replacement. The vehicle is less than one year old. I am aware of numerous reports of ICCU and 12V battery failures on this model, and my experience is consistent with them. A sudden loss of propulsion while driving is a safety hazard, and I am concerned this defect can occur without warning at highway speeds.

SERVICE BRAKES

I am reporting a serious suspected brake malfunction involving my 2025 Hyundai IONIQ 5, VIN [XXX]. While driving straight on a wet road during rainy conditions, I pressed the brake pedal to slow down. The pedal felt soft and sank toward the floor, but the vehicle did not slow down or respond as expected. The vehicle continued moving, and an accident occurred. The vehicle sustained major damage and may be a total loss. I am concerned that the braking system may have malfunctioned. I am requesting that NHTSA review this incident for a possible safety-related defect affecting the braking system of the 2025 Hyundai IONIQ 5. I request that this complaint be considered alongside other reports of braking problems involving the same vehicle or braking components. I would like the vehicle and its braking system to be inspected before it is dismantled or disposed of, and I ask that relevant diagnostic information be preserved. Please investigate whether this incident may be related to a safety defect that could affect other drivers. Additional information, including the accident date, vehicle mileage, warning lights, and accident report, can be provided as available.

POWER TRAIN, ELECTRICAL SYSTEM

I am writing to document my case regarding my leased 2025 Hyundai Ioniq 5 XRT. Vehicle: 2025 Ioniq 5 XRT, VIN [XXX] Lease start / delivery date: Odometer: 4,368 miles Servicing dealer: Stevinson Hyundai, [XXX] Case number: XXX What happened: On Saturday, XXX, while I was driving, the vehicle displayed "Stop vehicle and check power supply" with the red 12V battery warning and the master warning light, and power was limited to approximately 25 mph. The high-voltage battery was at 66 percent. I was able to get the vehicle home at reduced speed, and Hyundai Roadside Assistance towed it to the dealer the same day. The symptoms are consistent with an ICCU failure, pending the dealer's diagnosis. Photos of the instrument cluster are attached. I consider a sudden loss of drive power at 4,368 miles to be a safety-related defect, and I have reported it to NHTSA. My situation: This is one of two vehicles in our household, and both of us need to get to work. The dealer is about 30 miles from my home. I am without transportation as of September 19. What I am requesting: 1. Written authorization for a rental vehicle starting immediately and continuing until my vehicle is repaired and returned, including the approved daily rate and how billing or reimbursement will work. 2. A parts availability check and estimated repair date as soon as the dealer confirms the diagnosis. 3. If the vehicle is out of service for an extended period, reimbursement of my lease payments for the time I cannot use it. 4. Confirmation of the warranty coverage that applies to the ICCU on this VIN, including any extended ICCU coverage. I am keeping a record of the days the vehicle is out of service, starting XXX. Please reply in writing so I have everything documented. Thank you for your help, [XXX] [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

STEERING

Driving at highway speeds, the front end feels unstable. It feels as if the tires are jumping around and will move the car to the right or left. It is difficult to maintain control. I had it into the dealer shortly after I bought the car to complain about what I thought was a front end alignment problem. They didn't think there was an issue until they got it into the shop. They said afterwords that it WAS OUT OF LINE. But their fix did not hold, so I went in again for the one year maintenace and mentioned the problem, but they said it was not out of line. Well, The problem still exists. Something serious is wrong and needs to be fixed.
