On [XXX], I was driving at about 45mph on main road and heard a pop noise from under car followed by warning display on dash (messages and images showing no charging to wheels) and immediately experienced a tremendous decrease in power. The foot pedal was no longer responding as the power continued to decrease over a period of approx.20 minutes. I was very lucky not to get rear ended as it was rush hour and there was heavy and fast traffic on that road. Engaging emergency flashers appeared to slow the car further as I kept ducking in and out of traffic trying to get home safely. The car was towed to the closest dealership (Preston Hyundai in Millsboro) and has been there since. Therefore, it is available for inspection. Although I have called the service dept. numerous times, I have not gotten any answers as to problem, fix or given a loaner /rental. It will be 3 weeks this coming Monday. They told me that the car has been run through tests and the engineers have not "diagnosed" the problem! I was told it might be the ICCU and that they have 2 other cars in the lot behind me with similar issues. The vehicle was up to date on all recalls (including the prior recall on ICCU issue). Therefore, it has been inspected previously. There was no warning prior to the failure. i noticed that the VIN is not on the list of recalled vehicles- it should have been!! I have contacted the Hyundai national customer service (855-371-9460) on 3/6/25 and explained I was getting the run-around and not being furnished with loaner/rental. I do feel that they should be responsible for the towing cost as well. I was told that a case manager will contact me within 2-3 business days which means sometime next week. Hopefully, he/she will handle the customer service issue with re: to loaner/rental. I hope you will be able to get action on resolving the car issue as those cars are "accidents waiting to happen"!!

While running errands, my Ioniq 5 suddenly made a pop sound, and the dashboard displayed a “Check Electrical System” warning, followed by a loud alert and a message instructing me to “Stop Vehicle and Check Power Supply.” I was able to safely park in a lot and called for a tow. At that point, the car was still operable, but after being unloaded from the flatbed, it would no longer turn on. The issue was diagnosed as a failed ICCU, and I was informed it will take one month to receive the parts and complete the repair. Had this failure occurred on a highway or busy street, it could have been extremely dangerous. I am fortunate that it happened in a safe location.
While driving my car in a high traffic area, it stopped working. Completely stopped. It would not accelerate whatsoever and I was forced to stop on this busy street, luckily right past an intersection. This is a known problem with this vehicle.

While driving my car in a high traffic area, it stopped working. Completely stopped. It would not accelerate whatsoever and I was forced to stop on this busy street, luckily right past an intersection. This is a known problem with this vehicle. Yes there is a recall on the car but getting scheduled to have the recall done has been a very long process with me being told it would be months to fit me in.
ICCU failure resulted in a loud pop and then loss of most power. Was still able to move the car but was limited to ~22 miles per hour. Had to be towed to the dealer. Tow and service from the dealer is pending, but my understanding from talking to service is that this is a relatively common issue and will require replacement …

ICCU failure resulted in a loud pop and then loss of most power. Was still able to move the car but was limited to ~22 miles per hour. Had to be towed to the dealer. Tow and service from the dealer is pending, but my understanding from talking to service is that this is a relatively common issue and will require replacement of the ICCU unit. The car has had multiple recalls to attempt to address this issue preemptively including a little over a month ago. There were no issues reported at that the time of those recall services. Incident occurred without warning. After the pop and loss of power electrical and service warnings popped up all over the dashboard.
After having recall service of ICCU applied, the symptoms that initiated the recall surfaced. I had not driven 200 miles before I received a warning that the electrical system needed attention, followed by a warning the battery (12volt) had an issue and to stop driving. On top of that, the car will not accept a charge.
ICCU fuse blown. Most likely the ICCU failed. Getting it towed now.
I took my Hyundai Ionqi 5 Electric Set AWD in for two recalls. After picking up the car, I left the car dealership and merged onto the highway.

I took my Hyundai Ionqi 5 Electric Set AWD in for two recalls. After picking up the car, I left the car dealership and merged onto the highway. Within 1-2 minutes after I left the dealership, the dashboard was flashing red circle with an exclamation point that said the electrical system was low. I could no longer accelerate. I proceeded to move to the right with traffic traveling 60-70 mph. I was extremely scared as I tried to drive on the side of the road. I had to turn on my flashers to get to the next exit. I was going about 20-25 mph. As I tried to go back to the dealership, it died in an intersection. Again, I was concerned about my safety with my car unable to move. I had the car towed back to the dealership. They said it was the 12 volt battery, but when they looked further they said it was the Integrated Charging Control Unit (ICCU) which wasn't working. The dealership said that they checked the 12 volt battery and the ICCU when they finished the recalls and everything was OK. That doesn't make any sense when everything dies within 1-2 minutes. Then the dealership said they would not be able to get a part until the end of March.
After taking 2023 Hyundai Ionic5 in three times due to recall notice for ICCU software update over the course of 18 months, ICCU still failed causing complete loss of power. Car has less than 5,000 miles on it. Have been told no estimate available on time it will take to get part replacement. Could be months.
ICCU error, check power source error then all electrical in the vehicle went out. No power steering, no acceleration, anll screens went black, all recalls addressed.

1PE23011 · Loss Of Motive Power
Opened Jun 8, 2023 · Closed Apr 17, 2024
Status: closed (inferred from source dates) · Electrical SYSTEM:12V/24V/48V Battery; Electrical System:propulsion System:dc/dc Converter
On June 8, 2023, the Office of Defect Investigation (ODI) opened PE23011 to investigate allegations of loss of motor power on model year (MY) 2022 Hyundai Ioniq 5 vehicles. Some consumers reported loss of motor power immediately after a warning lamp illumination or reduction of motive power while the vehicle was in motion. This investigation found that the Integrated Charging Control Unit (ICCU) may be subject to various conditions such as overcurrent, overvoltage induced at the end of charging, and certain thermal loading during operation that can damage its internal components and open the ICCU fuse, resulting in an inability to charge the 12-volt battery. The vehicle could eventually lose all motive power, increasing the risk of a crash. In July 2023, Hyundai issued a service campaign to address certain MY 2022-2023 Ioniq 5 and MY 2023 Ioniq 6 vehicles that may have low 12V auxiliary battery charging occurrences due to an ICCU fault and may set the DTC P1A9096 “DC/DC Converter Input Voltage Sensor Fault”. On March 15, 2024, Hyundai filed Safety Recall 24V-204 for 98,878 MY 2022-2024 Hyundai Ioniq 5 vehicles and MY 2023-2024 Hyundai Ioniq 6, Genesis GV60, Genesis GV70 “Electrified” and Genesis G80 “Electrified” vehicles. The recall remedy provides an inspection, and if necessary, a replacement of the ICCU and the associated fuse. The ICCU software reduces the risk of overcurrent and implements voltage peak reduction at the end of EV battery charging. The recall also includes a software update that revises the electric water pump operational threshold to reduce thermal loading during charging and driving. In view of the recall action being taken by Hyundai, ODI is closing this Preliminary Evaluation. The agency reserves the right to take additional action if warranted by future circumstances. To review the reports cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.
