2026 GENESIS GV70 Electrical System Problems

Tried to start the car and got a several warnings of "turn off vehicle and check EV system" and "power limited". This is similar to the ICCU failure issue other people have reported.

National Highway Traffic Safety Administration Office of Defects Investigation 1200 New Jersey Avenue SE Washington, DC 20590 Subject: Safety Defect Complaint – Integrated Charging Control Unit (ICCU) Failure Vehicle: 2026 Genesis GV70 Electrified (EV) VIN: [XXX] To Whom It May Concern, I am submitting this complaint to report a safety-related failure involving my 2026 Genesis Electrified GV70, which experienced a sudden “Check Electric Vehicle System” warning consistent with a failure of the Integrated Charging Control Unit (ICCU). Incident Summary On February 5, 2026, at approximately 4,480 miles, the vehicle displayed a “Check Electric Vehicle System” alert and was no longer safe to operate. Due to the risk of propulsion loss and electrical system malfunction, the vehicle required flatbed towing to an authorized Genesis dealership for evaluation. A dealership service advisor subsequently informed me that the vehicle has been diagnosed with an ICCU failure, a component responsible for charging the 12-volt...

The Instrument Cluster Screen went blank (OFF) while driving 65mph on the freeway. The vehicle mechanically kept functioning. I had no gages. The system began to reboot within a few seconds as I was attempting to pull over to the shoulder of the freeway. My vehicle continued to function normally so I drove home. My wife was very startled and shaken. This happened again so I took vehicle to the dealership service dept. where they performed a diagnostic test finding “ technical glitches” as I was told. They ordered a new screen. I drove off with my car until a new screen arrived two weeks later. The screen again went blank on the city streets a day or so before the new screen arrived. I only drove my car as necessary while my wife refused to do so and never had other passengers. I surrendered my car for repairs on...

I purchased a 2026 Genesis GV70 3.5T Sport Prestige (Certified Pre-Owned) on August 26, 2025, with ~100 miles on the odometer. At around 475 miles, the climate control screen went completely dark, rendering the HVAC and seat heating/cooling systems inaccessible via the center stack. While some touch-sensitive functions remain partially active (e.g., seat heater turned on and could not be turned off; AUTO and SYNC lights blink), no display is visible, making the system unusable. This poses a driver safety hazard—especially in foggy or cold conditions when defrost or rapid cabin adjustments are needed—and causes distraction and discomfort during operation, hot seats in the summer and cannot turn off. The vehicle was dropped off at the dealer (Genesis of Cary, NC) on September 11 and remains out of service awaiting a replacement screen (ETA September 24). I was told this was the first time the dealership had seen this issue....
