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.

HYUNDAI IONIQ 5 2024 STEERING

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.

HYUNDAI IONIQ 5 2024 ELECTRICAL SYSTEM

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: âStop vehicle and check power supplyâ 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 100Â°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 vehicleâ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 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.
