During routine driving, the vehicle suddenly displayed an electrical system. Error code followed several minutes later by a 12-volt battery error. The vehicle was stopped and turned off. When turned back on all warnings disappeared and vehicle was returned to service for approximately 3 MI before warnings appeared again. Vehicle was then parked as it entered limp mode with a maximum speed of 11 mph. manufacturers roadside assistance was called and arrived to jumpstart the 12-volt battery which resulted in the vehicle turning on but not charging despite sufficient charge in the high voltage battery. Vehicle was stranded in a secure parking lot after hours with Windows unable to be closed and doors unable to lock. The vehicle is immobilized due to being unable to put the vehicle into neutral to move it to a suitable location for a tow. Vehicle was certified by dealership as a certified pre-owned vehicle approximately 45 days ago. All listed recalls have been checked and no undue stress has been placed on the vehicle since purchase. Vehicle stranded to adults and one toddler in 80 plus degree heat without any ability to remove the car to a safe location or secure transportation to an appropriate business.

This is an EV . We use the regenerative braking to slow down. This car has both a front and rear dash cam. The car is about two and a half years old and has about 20,800 miles. We were approaching a red traffic light with several vehicles stopped in front of us. My partner was driving and had slowed to 8 mph, with her foot off the accelerator, advancing slowly towards the car in front of us when the vehicle experienced unanticipated, rapid acceleration. With quick reflexes, she was able brake hard and avoided a collision. Ten minutes later she was parking at our house, going 4 mph and it did it again, coming within four feet of the building. Neither time was she touching the accelerator, but the car accelerated like the accelerator was pressed to the floor. This is very dangerous.

On June 13, 2026, my 2024 Hyundai Ioniq 5 experienced a sudden and dangerous propulsion failure while in active motion. The vehicle had approximately 9,447 miles on it and was at 58% battery charge at the time of the incident. The vehicle was leased in January 2025 and has been serviced exclusively at the Hyundai dealership. While driving with two occupants, the vehicle abruptly lost all ability to accelerate. The dashboard displayed a critical warning: “Stop vehicle and check power supply” along with a red battery icon. This failure occurred without warning and immediately placed us in danger of being struck by surrounding traffic, as the vehicle could no longer maintain speed or respond to throttle input. I was able to coast the vehicle off the roadway. Shortly after stopping, the vehicle issued an additional warning stating that auxiliary functions were draining the battery. Within moments, the vehicle shut itself down completely. This left both occupants stranded in extreme heat (over 100°F) with no air conditioning, no ventilation, and no ability to restart or power the vehicle while waiting for rescue. This created a serious risk of heat-related medical distress in addition to the initial roadway hazard. The vehicle’s complete loss of propulsion followed by a full electrical shutdown represents a severe safety defect. At no point should an electric vehicle with more than half a charge and fewer than 10,000 miles lose propulsion during active driving or shut down all systems while occupants are inside. This incident posed a significant risk of collision, injury, or heat-related harm. I am requesting that NHTSA investigate this failure mode, as it may indicate a broader defect affecting the propulsion or battery management systems of the Hyundai Ioniq 5. The vehicle is currently at the Hyundai dealership undergoing diagnostics and they confirmed they had difficulty jumping it to move it from where the tow truck had parked it on arrival.

I am writing regarding a very serious and frightening safety incident involving my 2024 Hyundai IONIQ 5. While driving through a busy intersection in California, the vehicle displayed the warning message: “Stop vehicle and check power supply.” Within approximately one minute of that warning appearing, the vehicle completely lost power and became inoperable in the middle of the intersection. The shutdown occurred without warning and created an extremely dangerous situation. The vehicle’s hazard lights would not function because the car appeared to be entirely without power. Traffic continued moving around me while I was stranded in the intersection, and I genuinely feared that another vehicle could collide with me. I ultimately called 911 because the situation was unsafe and I could not move the vehicle. Police responded and directed traffic until the vehicle could be towed. Hyundai dealership had the vehicle for 22 days and diagnosed it as a faulty ICCU (Integrated Charging Control Unit) which they replaced for no charge. This incident has caused me to lose confidence in the safety and reliability of this vehicle. A complete loss of propulsion in active traffic — especially accompanied by failure of the hazard system — is an unacceptable safety risk. I no longer feel safe driving this vehicle. Hyundai of America would not let me cancel the lease early due to safety concerns.
I received a warning on the screen that said "Stop vehicle and check power supply". Later I got a different message about the 12V system. I checked the error codes with an android app and got error codes P1A90 and PPOC17.
This is the second time the ICCU failed. The car is waiting for a full EV battery replacement. The first time the failure happened on 12/11/25, at 9,165 miles, the alert happened just before the car came to a full stop as we were driving along the road near our house, it was very difficult to steer, we were sort of stopped in th…

This is the second time the ICCU failed. The car is waiting for a full EV battery replacement. The first time the failure happened on 12/11/25, at 9,165 miles, the alert happened just before the car came to a full stop as we were driving along the road near our house, it was very difficult to steer, we were sort of stopped in the road and had to get it towed. The second time the alert came on 4/16/26 and we were able to get it to the dealer.
The vehicle flashed a warning and suddenly lost power, forcing me to pull over or be stuck in the middle of the road. The vehicle could no longer be driven, as this problem occurred quickly after subsequent restarts. I had the vehicle towed to the dealership, who confirmed it was a broken ICCU, and stated that this had been happ…

The vehicle flashed a warning and suddenly lost power, forcing me to pull over or be stuck in the middle of the road. The vehicle could no longer be driven, as this problem occurred quickly after subsequent restarts. I had the vehicle towed to the dealership, who confirmed it was a broken ICCU, and stated that this had been happening a lot to the Ioniq5s. The replacement part was on backorder. It ended up taking nearly 60 days for the replacement to arrive and to be installed.

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.
