In owners’ own words
Source: NHTSA complaint databaseFiled with NHTSA by the people who own these cars, about the electrical system. Quoted as written, with anything identifying removed; unverified reports — what was said, not a finding that it was true.
The Integrated Charging Control Unit (ICCU) failed on my 2025 Hyundai Tucson PHEV at approximately 6,600 miles. The failure manifested through multiple concurrent symptoms. First, the vehicle displayed a "car not charging" warning light and completely refused to accept an electrical charge when plugged into a charger.
My entire dashboard goes black and I lose all directions and functions in car. It happens when driving often. Additionally after taking to dealership, it's getting worse. Now warning lights come on and stay on such as master warning lights, batteries, power steering, etc.
Vehicle: 2025 Hyundai Tucson SEL Approximate Date of Incident: Description of Problem: While driving at normal speed, the dashboard display and exterior lights suddenly turned off, then reset. The speedometer and warning lights disappeared, then reappeared after a few seconds.
The contact owns a 2025 Hyundai Tucson. The contact stated that while driving at an undisclosed speed, the instrument turned blank for several seconds. The contact stated that the failure had recurred several times while driving. The vehicle was not diagnosed or repaired by an independent mechanic or dealer.
On two occasions, the dash lights kept blacking out, along with the Heads Up Display. On my way to the dealer for a maintenance appointment, all of the emergency lights came on and would not go away.
