EV system not working on car with 8k miles on it. Dealer backed up and cannot offer rental car. This is a safety issue for me . This is a KNOWN issue for Hyundai and they are not recalling and their dealers are not equipped to resolve quickly.

I was slowing down, actively pressing the brake pedal to bring the vehicle to a full stop. As the car decelerated to what my senses and perception registered as a full stop, I pressed the “P” (Park) button while keeping my foot on the brake pedal. I felt the physical click of the “P” button under my thumb while still holding the brake, and my mind registered that the vehicle had successfully transitioned into Park. Before turning around, I visually confirmed that the vehicle had come to a complete stop. Believing it was fully secured in Park, I turned my head to check on my child in the back seat and naturally released the brake pedal completely. However, the system had actually rejected my command. I assume that the vehicle likely still had a small amount of speed at the exact millisecond I pressed the button, and the computer automatically blocked the “Park” command and kept the car in gear. Because an electric vehicle operates in almost complete silence, with no engine noise or vibration to indicate that it is still in gear, there was no auditory or physical cue to alert me that the car was moving when I released the brake. While my attention was turned toward the back seat for a few seconds, the car quietly began to creep forward, leading directly to the collision with the car in front of me. Following the accident, I found that the vehicle produces slightly different sounds when Park is rejected and when it is successfully engaged. However, the owner’s manual describes only the dashboard message and does not describe these sounds or explain how to distinguish them, so their meanings may be learned only through the failure. At the time of the incident, I was not familiar with the distinction between these two sounds. Because my brain processed the physical press of the button as a successful action, and I had visually confirmed that we were not moving, my focus immediately shifted to my child. I was entirely misled by the digital interface.

Description of Safety Defect:The integrated Forward Attention Warning (FAW) driver-monitoring camera located on the steering column continuously fails to track facial structures or pupils during routine daytime driving. This occurs despite maintaining a proper driving posture, adjusting the steering column layout, and removing any facial obstructions.Safety Consequences:When the system falsely registers a "distracted driver" state due to its faulty sensor calibration, it routinely triggers erratic high-pitched chimes and immediately disables active highway driver assistance systems, including Highway Driving Assist (HDA), Lane Keeping Assist (LKA), and Smart Cruise Control. This abrupt loss of active steering guidance and vehicle speed maintenance creates sudden, hazardous driving situations on open highways. Furthermore, to get the faulty alert chimes to clear, the driver is forced to take their eyes off the roadway to stare directly into the steering column sensor camera, actively causing driver distraction.

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. It restricted me from going over 10 mph on Highway 1 and I eventually pulled over the side of the road and got towed to the dealership. The car is home with me now but I do not feel safe driving this vehicle after all of the reports of ICCU failures. I am very concerned this will happen again and in a more dangerous situation. I was also stranded by this car in March 2026 with a dead battery.

During a family road trip, my 2025 Hyundai Ioniq 5 (~9,000 miles, less than one year old) suddenly showed red "Check Electric Vehicle System" and 12V battery warning lights and then completely lost power. The 12V system failed entirely - the vehicle could not be driven or shifted, and the doors and the rear hatch could not be locked or unlocked. It had to be flat-bedded to a Hyundai dealer because it was completely inoperable. The dealer diagnosed a failed ICCU (Integrated Charging Control Unit) and a blown ICCU safety fuse (fault code P1A9096) and is replacing both under warranty; the component is available for inspection. The ICCU converts high-voltage battery power to charge the 12V system; when it fails, the vehicle loses all electrical power and drive capability. The warning lamps appeared immediately before total power loss, with no prior symptoms at the last scheduled service. This is a known, safety-critical failure on this platform: a sudden, complete loss of power can strand occupants and, if it occurs while driving, cause loss of motive power - a serious crash risk. My vehicle was stationary when it failed, but the same failure at speed would be extremely dangerous. I have video evidence of the car completely bricked out.
