What 399 owners told NHTSA about the 2022 Hyundai Ioniq 5 Bev

Component that failed: High-voltage main battery pack assembly and associated electrical architecture. The vehicle and the component are currently located at my home and are available for inspection upon request. Description of Incident & Safety Risk: While attempting to drive the car and when connected to the vehicle to a standard charging infrastructure, a catastrophic internal failure occurred within the high-voltage system (Diagnostic Trouble Code P1AA600). Upon attempting to plug the vehicle in, active electrical arcing and physical sparks emanated from the high-voltage architecture. This structural manufacturing component defect presents an immediate, severe, and active fire and safety hazard to the occupants, the vehicle, and any surrounding property. The vehicle is currently completely un-driveable and unsafe to connect to any power grid. Dealer Confirmation & Inspection: The vehicle was driven to a certified manufacturer dealership service center. A certified dealership technician formally inspected the vehicle, reproduced the fault, and explicitly documented the active electrical arcing and sparking coming from the high-voltage pack in the official service records. The vehicle history was also escalated to the manufacturer's executive consumer affairs team, who acknowledged the intake statement but refused to authorize a remedy or repair. Warning Symptoms: There were no long-term warning lamps or prior symptoms leading up to the structural breakdown. The high-voltage system failure occurred suddenly and catastrophically, immediately triggering a critical malfunction indicator on the dashboard cluster at the time of the failure.

While the vehicle was parked in a garage and charging overnight, I briefly went to the vehicle to retrieve an item from the back seat. I was barefoot at the time. I opened the driver‑side rear door and reached inside with my right hand while my left hand was near the upper door area where the door seal is located. When my left hand grazed the door frame, it felt unusually sharp. When I touched the area again to determine what was sharp, I received a significant electric shock. There were no warning lights, messages, or prior symptoms before the incident. The presence of electrical current on an exterior door surface poses a safety risk during normal vehicle use.

I was coasting into a library parking space with my foot off the accelerator. The car accelerated even with my foot on the brake, jumped a curb and was stopped with above ground tree roots. The dashboard should have been lighted up with collision warning indicators and the automatic braking should have engaged. It did none of that. The car was totaled. Nothing was ever checked to see if it was a mechanical error. My insurer totaled the car.

ABS or All wheel Drive did not seem to work while driving on a Highway, and I tried to stop as there was another vehicle on the road which was spinning out of control. If ABS was activated, the car would have stopped, and similarly if All wheel Drive was working, car would not have spun out of control.
