The 12 volt battery (which is less than 6 months old) died on two separate occasions in the span of 4 days. Each incident required a call to emergency roadside assistance for a jump start. This is a safety issue. If the 12 volt battery dies while driving, the car will display a warning message instructing the driver to pull off the road immediately and shut off the car. The car will also lose power and cease operating shortly after this message appears. After the second incident, I took the car to my local Hyundai dealer but after having the c…
While driving home, I experienced a sudden and complete power system failure in my Hyundai Ioniq 5 N. The failure occurred shortly after starting the drive, and was preceded by a faint "pop" sound. Within moments, the dashboard displayed the following critical warnings: Red 12V battery icon Red warning: "Stop vehicle and check power supply" Turtle icon (indicating limp mode / low power) Brake warning light ⚠️ The vehicle immediately entered limp mode, then fully lost power within approximately 3 minutes. I was able to safely pull into a near…
The Hyundai Ioniq 5N features a unique mode called N e-Shift which enables a software simulated 8-speed transmission that attempts to emulate the gear changes and driving dynamics of a traditional automatic transmission that would be found in an internal combustion engine vehicle. Unfortunately, the mode has a dangerous component in the programming, wherein, when the driver has been accelerating in a spirited fashion and lifts off the throttle, the vehicle CONTINUES TO ACCELERATE for approximately 1-2 seconds despite there being no input from …
The contact owns a 2025 Hyundai Ioniq 5 N.

Additionally, the contact stated that upon depressing the brake pedal, the vehicle responded as intended after three seconds. The vehicle was taken to an unknown dealer, where it was diagnosed and determined that the ABS module had failed, and a software update was needed. The vehicle was not repaired.

The dealership performed the software update from the Hyundai recall 275. After the update, when using the e-shift feature in N mode the car sometimes will accelerate out of control on its own without the accelerator pedal being engaged. Hyundai also changed the motor sounds and e-shift feel.

The contact owns a 2025 Hyundai Ioniq 5 N. The contact stated that while driving at 40 MPH, the service battery immediate warning light illuminated. A dealer was contacted. The vehicle was taken to the dealer because the ICCU unit needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 8,000.
What happened to me is a common problem with these models. I had an issue with the 12 V battery not being charged by the main battery as it should be. This led to a blowing of the main fuse which took out the ICCU unit. This seems to be fairly prevalent from what I can tell from online forums, and there needs to be a recall from Hyundai.
ICCU failure and fuse, the car became unoperational and needed to stop. The car would no longer charge the 12V battery, and the EV battery would not charge. Hybrid Control Problem Detected at 3,160 miles. DTC P056216
I have experienced two high voltage battery failures both requiring hv battery replacement. The first occurred around 6000 miles and the second occurred around 13,000 miles. I also had several dead 12v battery episodes where the card would be dead; even when plugged into the home charger overnight. I had to replace the 12v battery at 12000 miles.
