The ICCU (Integrated Charging Control Unit) failed with DTC P1A9096 and I was driving at approximately 25-30 MPH on 01/17/2026 at approximately 5:40 pm in approximately 32 degree temperature. The car had just been disconnected from a hardwired Chargepoint Home Flex 11.5 kw 48A Level 2 home charger with a NACS connecter (so no adapters used), though the charging had mainly ended at approximately 5:24 am that same morning (after reaching the preset charging limit of 80% of battery capacity, I believe). That charging session provided 45.572 kWh of energy over approximately 4.5 hours and then the vehicle sat, still plugged in, for approximately 12 more hours until disconnected to drive it. After driving approximately 1-2 minutes on residential streets, I heard a muffled 'pop' sound behind the front seats, and the vehicle dashboard suddenly showed 'check electrical vehicle system' and 'stop vehicle and check power supply'. The vehicle suddenly had limited capabilities, including speed, and at that point gave a limited, unspecified, amount of time to get off of the road to safety. The vehicle is currently with a Hyundai dealer (Hyundai of 110 in Farmingdale, NY) who has since confirmed it was an ICCU failure. They are waiting on a new ICCU, which is on back order. The vehicle had been leased, new, in June of 2025 and after that, was driven approximately 9,506, miles (mostly highway) and never exhibited any sounds, warning lights, control issues, or any other indications that there was any problem or that there would be any sudden problem with the vehicle.

The ICCU (Integrated charging control unit) failed, causing my car to go into "Limp mode" where it was unable to accelerate over 44 mph. This put my safety at risk as I was unable to accelerate on the freeway. The Hyundai dealer confirmed the problem and it is still there, with no estimated time for repair due to a shortage of replacement part. It was not inspected by the police or insurance. There weren't any warnings or symptoms prior to the failure. Hyundai has issued recalls for 2022-24 models for this problem but not the 2025, although it appears they have not fixed this for 2025 models.
The vehicle's ICCU failed after 7 months and 7k miles of driving. This is a known issue that Hyundai has not addressed or issued a recall for.
Vehicle's charging system failed when vehicle was remote started. Specifically the ICCU failed, and drained the low voltage system of power. Vehicle would not move, and left me stranded. Currently, Vehicle is at a dealership awaiting inspection for warranty repair. Multiple warning lights, DTC P1A9096.
The integrated charging control unit (ICCU) failed on [XXX] rendering the vehicle inoperable and powerless. Warning lights did illuminate on the dash shortly after a popping sound, along with warning sounds. This occurred just minutes before I was going to enter a freeway.

The integrated charging control unit (ICCU) failed on [XXX] rendering the vehicle inoperable and powerless. Warning lights did illuminate on the dash shortly after a popping sound, along with warning sounds. This occurred just minutes before I was going to enter a freeway. The vehicle was towed to the nearest Hyundai dealer (Hanlees Hilltop Hyundai, Richmond, CA) on Jan. 7. The ICCU failure was diagnosed on Jan. 9. Hanlees Hilltop ordered replacement ICCU parts on Jan. 9. (At Hanlees, my customer # is [XXX]. The work order # is [XXX]. I checked with my service advisor at Hanlees Hilltop today (Feb. 10); the parts remain on backorder with no estimate for arrival. I take note that the ICCU was subject to recall in 2022, 2023, and 2024 Hyundai Ioniq 5 models. I am inquiring as to whether there will be a similar recall for 2025 Ioniq 5 models. About an hour of research online strongly suggests that ICCU issues remain a continuing problem. I filed a case with Hyundai Motor America (case# [XXX]). So far, the executive case manager assigned to me has not been helpful. I request an NHTSA Office of Defects Investigation to ascertain whether it is advisable and safe for Hyundai to do nothing about this critical problem for consumers. Further, two more questions should be explored: 1) should 2025 Ioniq 5 vehicles be recalled because of the ICCU; and 2) should the ICCU itself be improved or modified, given that it has been the cause of recall in the previous three model years? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
While charging the vehicle, I heard a loud pop and the charging session stopped and could not be restarted. An error warning icon appeared on the dash with a battery icon. Also a car with an! Icon and a large circle stating check the electrical system. I was able to drive a few miles before the car completely died.
ICCU FAILURE. Confirmed by dealer. Warning lights to check battery. Almost total loss of power. 4000 miles on the car. Service center has no estimate on when parts are available.
