GENESIS Complaints

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 battery and maintaining critical electrical systems. Failure of this component can result in loss of drivability, propulsion limitations, or vehicle shutdown, creating a significant roadway safety hazard. Safety Concern Failures of the ICCU have been widely reported across Hyundai, Kia, and Genesis electric vehicles and have been the subject of prior recalls due to the potential for unexpected loss of motive power while driving. Despite prior recall actions, failures continue to occur, including in my vehicle. Current Status The vehicle remains out of service pending repair, and no written repair completion timeline has been provided. The failure rendered the vehicle unusable and required emergency towing. I respectfully request that the Office of Defects Investigation review continuing ICCU failures affecting Genesis, Hyundai, and Kia electric vehicles to determine whether additional corrective action or expanded remedies INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATIO

While driving at highway speed, the vehicle experienced a sustained loss of motive power. Despite the accelerator pedal being fully depressed, the vehicle would not accelerate beyond approximately 62 mph. Based on the symptoms and prior service history, the malfunction appears related to the fuel/propulsion system, engine, or powertrain. The vehicle is currently parked and available for inspection upon request. This failure placed the safety of the occupants and other motorists at risk. The vehicle was unable to safely accelerate, merge, pass, or respond to traffic conditions. Hazard lights were activated, and the vehicle was forced to remain in the slow lane of the highway for an extended period to avoid being struck by faster-moving traffic. The problem was reproducible and occurred repeatedly during the same trip. Acceleration was tested multiple times, and each attempt resulted in the same loss of power with no response to throttle input. The condition persisted for the entire drive. The vehicle has not yet been inspected following this incident. However, the vehicle previously received a manufacturer warranty repair involving replacement of the high-pressure fuel pump, and the manufacturer has issued a warranty extension for this component. The loss of motive power occurred after that repair. No warning lamps, alerts, or messages were observed prior to or during the failure. There were no warning symptoms immediately preceding the loss of motive power. This loss of propulsion at highway speed created a serious and immediate safety hazard due to the inability to maintain normal traffic speed or maneuver safely.

Had Recall 031G completed on 01/20/2026. Bluetooth continues to glitch and infotainment system continues to restart and go black while driving leaving driver without key information to operate vehicle posing a crash risk

The forward collision warning comes on and the car completely stops. We are traveling and it happened twice on busy hwy. We were not hit but came perilously close both times. We took our car in for service and asked that they disconnect this because we have had the problem before. They said they did. It has find for about 2 months and now is starting again even though it’s supposedly disconnected. There is no warning before this happens.

The fuel delivery system, specifically the fuel pump and fuel rail pressure system, has malfunctioned and continues to trigger diagnostic trouble code P0191 (fuel rail pressure sensor range/performance), despite a prior recall-related software update performed by the dealer, and the vehicle and all affected components are available for inspection upon request. While driving on the highway, the vehicle suddenly began stalling, hesitating, and hard jerking before losing power and entering limp mode, limiting speed to under 50 mph and forcing me to immediately pull over, which created a serious safety risk to myself and other drivers due to the sudden inability to maintain highway speeds. The issue has been confirmed by an authorized dealer through repeated diagnostic scans showing the same fuel system fault codes, and the dealer has determined the fuel pump now requires replacement, indicating the recall update did not resolve the underlying failure. The vehicle has been inspected by the dealer on behalf of the manufacturer, and prior to the failure the check engine light illuminated and has remained on since, with symptoms escalating abruptly and occurring without warning, making this an ongoing and unpredictable safety issue.

On multiple occasions when turning left the emergency breaking system stops and stalls out the car.

My 2024 GV80 with approximately 15k miles started completely powering off while driving multiple times and the vehicle started itself while in my enclosed garage space with no one in the vehicle, no button/brake pressed, not key fob pressed. I turned this into the dealership for manufacturer repair on 9/13/25 and as of today, 2/5/26, I still do not have my car back. The dealership explains there is an intermittent parasitic draw that they have been unable to identify. The battery drain, they claim, resulted in the car stopping by itself and starting by itself. The company has refused buyback under Lemon Law (not covering CPO), letters to the CEO have gone unanswered, multiple claims with Genesis corporate have resulted in no help and the local dealership is horrendous- no response, having the vehicle 5 months, no timeline.

The contact owns a 2024 Genesis GV70. The contact stated that while driving at 20 MPH, the vehicle's gear shifter independently shifted from drive(D) to neutral(N). A dealer was contacted. The vehicle was taken to an independent mechanic to be diagnosed. The contact was informed that the gear shift selector switch needed to be replaced. The gear shift selector switch was replaced, and the vehicle was repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 6,500.

On Feb. 2, While driving slowly in a school zone, with no cars in front of me, my car proceeded to abruptly brake over and over 5 times. The warning came on the dash "front end collision". I also had NO CONTROL over the car! I was extremely fortunate not to be rear ended during this event. At that time I immediately called my Genesis dealer who asked if it was snowing and often this can occur! What???? No it was NOT snowing and HOW could I drive a car knowing that this dangerous event can happen????? The Service Advisor was NOT very helpful, offered NO solutions and I was very scared driving my car home to say the least! Today, Feb. 3 (the next day following this incident) I called my Genesis dealer again asking for the Service Mgr. The car was now showed a warning light indicating a malfunction in the Active Air Flap system and the Service Mgr. informed me that the car is NOT SAFE to drive and they would tow it to the dealership.

The contact owns a 2019 Genesis G70. The contact stated that upon advising a friend that the turbocharger oil feed pipe was made of plastic, the contact was informed that there was a recall related to the issue. The vehicle was taken to the dealer, where it was confirmed that another dealer had marked NHTSA Campaign Number: 24V191000 (Engine and Engine Cooling); as completed even though the recall repair was not performed on the vehicle. The dealer and the district engineers inspected the vehicle and confirmed that the recall repair was not performed. The dealer notified the manufacturer of the issue and sent supporting pictures to the manufacturer; however, the manufacturer denied coverage after receiving several claims from the dealer. The dealer then advised the contact to report the issue to the NHTSA Hotline because the vehicle was at risk of catching on fire. The contact had not yet experienced a failure.
