We were driving and vehicle suddenly showed multiple warnings including check forward/side safety system, check change lane assist, check inattentive driving warning, check lane safety system and then things went away and it showed 4 needs attention represented by triangle with exclamation point. We also seemed to lose power steering assist. It could drive but was "heavy". We were on highway trying to figure out what to do and what was wrong. Isolated stretch of highway at night. Suddenly the multiple warning flashed again. We were trying to determine what to do. The car seemed to drive fine except power steering seemed heavy.

Shift-by-wire system completely locked up, the vehicle refused to power down, and potentially the brake pedal switch failed. The vehicle became unresponsive while I was in a parking garage. Thankfully this didn't happen on the road. After spending over an hour trying random "tricks" found online, I eventually managed to turn the car off and restart it. I still don't know how.

Vehicle was towed to Stew Hansen Hyundai in Clive, IA. 12-volt battery, ICU and high-voltage fuse were replaced. My VIN did not appear in NHTSA recall lookup results for this issue.

"While driving a 2025 Hyundai Ioniq 6 at approximately 10,000 miles, the vehicle experienced a sudden, catastrophic Integrated Charging Control Unit (ICCU) failure with no advance warning. The vehicle instantly experienced a total electrical shutdown while the car was on the ramp. The failure completely bypassed and disabled standard safety redundancies: the electronic parking brake/emergency brake system failed , and the 12-volt backup battery died instantly, making it impossible to activate the hazard lights. The vehicle became a completely invisible, immovable dead weight on an active roadway, presenting an imminent, extreme threat of crash, injury, or death to myself and surrounding moto
