Owner report 11578415 · 2024-03-20 (March 20, 2024)
My vehicle was fully charged. About 1 mile after leaving my house, I received a warning message on my display (vehicle electrical system error or similar). Shortly after I received another message that power was reduced, then finally, "stop driving". I pulled into the nearest driveway and called roadside assistance. At that point, the vehicle was COMPLETELY dead. No lights or power whatsoever. I could not activate the car to shift into neutral. I had my vehicle towed to the dealership. They said it was due to a faulty ICCU and fuse. …

Owner report 11695346 · 2025-10-23 (October 23, 2025)
Despite being up-to-date on recalls for this vehicle intended to address failures with the integrated charging control unit (ICCU), I still experienced an ICCU failure. I was driving along a surface road at approximately 40 mph for about 9 minutes when I heard a pop that sounded like cargo shifting in the rear cargo area. The vehicle then flashed a "Check EV System" warning but otherwise continued to operate normally. About 2 minutes later, there was a warning to stop vehicle and check power supply. After I pulled into a parking lot, I restarte…

Owner report 11707684 · 2025-12-29 (December 29, 2025)
Shift gear was not engaging then i noticed the knob was slightly sticking out so I pushed it back in. The car changed gear then but it happened again a couple days later but this time the knob fell off while i was trying to push it back in. Brought to the dealers for inspection in September within a week after the problem started. Followed up twice now with no update as to when it will be fixed, I was told they will need to order part and that the entire shift gear will need to be replaced. They didn’t seem to be concerned about the safety of d…

Owner report 11523865 · 2023-05-25 (May 25, 2023)
When using the most aggressive braking energy recovery mode in the Hyundai Ioniq 5 (i-Pedal), the brake lights do not illuminate despite the aggressive nature of the braking provided by this mode. This mode brings the car to a full and complete stop and is very similar to commanded braking via the brake pedal. When using the L1-L3 braking energy recovery modes, the deceleration experienced by the car is more or less mild enough that it would be similar to a downshift in a manual transmission car. But the brake lights only illuminate if your fo…
