NHTSA investigations into the 2024 Hyundai Ioniq 5
An investigation is the step before a recall: the agency has seen enough
complaints to look into a pattern itself. An open one means it thinks
something may be wrong and nothing has been fixed yet.

Loss of Motive Power
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 I...
Recalls on the 2024 Hyundai Ioniq 5
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.
Hyundai Motor America (Hyundai) is recalling certain 2023-2024 Ioniq 5 vehicles. The high voltage battery cells may contain misaligned electrodes, which can lead to a fire while parked or driving.
Risk: A fire increases the risk of injury.

Canada — Transport Canada
Canada runs its own recall programme, and its campaigns do not
always mirror the American ones.
Recall 202470134,529 units in Canada
High Voltage
Issue: Over time, the integrated charging control unit (ICCU) could become damaged. As a result, the 12 V battery will not charge and could cause the vehicle to enter a reduced power mode. If this happens, and you continue to drive the vehicle, there could be a loss of power to the wheels. Note: This recall replaces Transport Canada recall no. 2024-174. Vehicles that were repaired under that recall also require this repair. This problem will cause a warning light to turn on and warning messages to display before any loss of power. For the Genesis GV70 and G80 models, only the electric versions (EV) are affected. Safety Risk: A loss of power to the wheels could increase the risk of a crash. Corrective Actions: Hyundai will notify owners by mail and advise you to take your vehicle to a dealership to update the vehicle software. The dealer will also inspect and, if necessary, replace the ICCU and ICCU fuse.
Recall 2024552824,695 units in Canada
Label
Issue: On certain vehicles, the compliance label may be missing information in French. The words listed on the label for "Tires", "Rims", "Front" and "Rear" appear in English only, when they should be listed as "Tires/Pneus", "Rims/Jantes", "Front/Avant" and "Rear/Arriere". Canadian regulations require this information to be listed on the label in both English and French. Safety Risk: These small errors do not affect vehicle safety. Corrective Actions: This is not a recall. The company has corrected the compliance label for all new vehicles.
Recall 202417419,443 units in Canada

POWER TRAIN
Was driving to vegas, it was 103-107 degrees After fast DC charging drivetrain had issues that when pressing acceleration the car would have almost a loss in power that caused a stuttering movement. If forcefully driven, the error message drivetrain electrical system would pop up. Issue can be resolved but only after letting the car stay in park for 10-15 minutes after finished charging. Issue was repeatable but only if weather was hot enough. This shouldn't happen or at least warn the driver to not drive for a certain period instead of guessing the issue.

STEERING
Vehicle steering or at least power steering failed catastrophically. Started with some electronic sounds at extremes of turning radius but subsequently failed completely and rendered car undriveable. Hyundai repair center attributed this to "excessive dirt and dust" or some external force, but was unable to substantiate or demonstrate any damage to parts they say need replacing. Ultimately this remains undiagnosed with regards to cause but dealer clearly identifies need to replace P/S motor and rack and pinion assembly. Insurance inspection documents no sign of external involvement in the failure. No warning lights/messages. Problem is repeatable. While failure would have been a safety risk at higher speed, it went from "noise at edge of turning radius" to "cannot steer the car" at a point in time where the car was moving at low speeds.

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.

TIRES
TIRE SIZE 235 / 55 R 19. Vehicle is a 2024 IONIQ 5. Issue began at/around 10k miles of use. Sound dampening foam inside of the tires comes loose and bunches up in the tire, creating varying degrees of car shaking and vibration. At its worst, the steering wheel and tires violently shake, especially between 50 - 75 mph. On the highway this causes a very dangerous situation of the driver fighting the wheel to remain safely within their lane. This can happen with no warning (or very little) as the vibration may be subtle at lower speeds on local roads, only to become unexpectedly extreme and violent while speeding-up to join highway traffic. Local Hyundai dealership inspected and tried rotating and balancing which did not fix the problem. Finally they removed the tires and inspected the foam which fixed the issue on one single tire. Cost was passed to the consumer, who is not at fault. And with only one tire addressed, the potential remains for each tire to experience the same failure without warning as time goes by. This is a very dangerous issue, well known as evidenced by complaints since 2023 online, and is going to cause accidents. It is unacceptable that drivers have risk their safety and that of other drivers if they lose control of the car due to the inability to control the steering wheel. Then have to pay to fix this issue or pay for new tires after only 10-12k miles.

ELECTRICAL SYSTEM
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.
