What owners report
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.
On April 20th while parking the vehicle suddenly had a power surge crossing over multiple curbs and across a parking lot and landscaped areas and hitting a tree. The vehicle refused to brake and the driver airbag never deployed.
I heard a loud popped sound from the back of my car while driving home. The car lost power and eventually died on the street. The war displacy came on to tell em to check electrical system.
Active powertrain failure on my 2022 Ioniq 5 SE, which poses an immediate and severe safety risk. On May 18, 2026, the vehicle suffered a catastrophic loss of power and a complete failure to charge.
The car engine shutdown mid drive. One minute before the complete stop, the car was stalling every 20 sec or so, then the acceleration stop responding to the drive pedal. The car was gliding to a stopping point. The "Engine " warning was on the display.
The car entered a failed ICCU state (not confirmed until the car was looked at by Hyundai at the dealership) while I was driving down to Ano Nuevo regional park. Received a warning on the dash that said that electrical system has failed and to pull over.
