The failure pattern owners describe
The 2023 GV60 electrical system is showing multiple failure patterns across 26 complaints. ICCU (Integrated Charging Control Unit) failures are the most serious: owners report sudden loss of propulsion at highway speeds with no warning, forcing emergency shoulder stops. The problem persists even after NHTSA recall 24V868000 and follow-up campaigns 907G and 025G were completed—one owner had the identical ICCU replaced but expects the same failure in 1–2 years since Genesis made no design changes.
Level 2 charging port overheating is nearly universal. The car is rated for 48-amp (11.2 kW) charging but the port overheats within 30–60 minutes. Genesis released TSB 23-EV-003h to throttle charging speed to 5.3 kW—effectively a workaround that doubles charging time from 7 to 10+ hours and doesn't fix the hardware defect. Some vehicles fail even at 28 amps.
The instrument cluster goes blank at startup, especially in cold weather, for up to 15 minutes. Owners lose access to speed, warnings, and safety diagnostics. This issue appears intermittent and doesn't always trigger fault codes, leaving dealers unable to confirm the problem during diagnosis.
A separate pattern involves 12-volt battery drain and high-voltage fuse failure, both leading to sudden power loss and immobilization. One owner's fuse failed two weeks after completing recall 021G, which was supposed to prevent exactly that.
Failure modes owners describe
ICCU (Integrated Charging Control Unit) Failure with Loss of Propulsion
The ICCU is failing catastrophically, cutting power to the drivetrain without warning. Owners report the vehicle suddenly losing propulsion at highway speeds, dropping to zero power, or becoming difficult to maneuver. Multiple complaints detail failures occurring even after NHTSA recall 24V868000 (Service Campaigns 907G and 025G) were completed, which were supposed to address this exact issue.
When: Highway speeds; one case at approximately 24,300 miles; one owner reports failure about 1-2 years after replacement
Symptoms owners cite: Sudden loss of propulsion or dangerous reduction in power; Complete loss of power while driving; Vehicle became difficult to maneuver; Loud audible pop from back seat (associated with HV fuse and ICCU); Battery draining excessively; Warning lights appearing after the failure (Check Electric Vehicle System, Stop vehicle and check power supply)
Codes mentioned: P1A9096
Repairs/costs cited: ICCU replaced under 10-year powertrain warranty; replacement ICCU is identical to failed unit with no design updates announced. Dealerships replacing with same part.
Recalls/TSBs owners mention: NHTSA recall 24V868000 completed with Service Campaigns 907G (10/26/23) and 025G (01/13/25); TSB issued for fuse problem; vehicle replaced under 10-year powertrain warranty in at least one case
Level 2 Charging Port Overheating and Charging Failure
The charging port overheats during Level 2 AC charging, causing the charging session to stop or fail. The vehicle is rated for 48-amp (11.2–11.5 kW) charging but cannot sustain this amperage without thermal issues. Genesis and Hyundai/Kia released TSB 23-EV-003h with a software patch that throttles amperage to around 5.3 kW to prevent overheating, but this is a workaround that does not fix the underlying hardware defect and doubles charging time from ~7 hours to 10+ hours. Some vehicles fail even at very low amperage (28 amps).
When: After approximately one year of ownership; during charging sessions
Symptoms owners cite: Charging port overheats within 30–60 minutes of use; Charging stops or fails intermittently; Charging unsuccessful message displayed; Vehicle refuses to charge; Error codes appear during charging; Charging stops after 7 minutes, 10 minutes, or 1 hour of charging
Repairs/costs cited: Software patch (TSB 23-EV-003h) throttles charging to 5.3 kW (from 11.2 kW), requiring 10+ hours instead of ~7 hours to charge. Owners also manually reduced charge rates (from 11.2 kW to 10.2 kW to 6.8 kW) without resolving overheating. Described as a charging port design defect.
Recalls/TSBs owners mention: TSB 23-EV-003h issued; software update released by Genesis, Hyundai, and Kia to detect overheating and throttle amperage; no permanent fix announced
Instrument Cluster Display Blank at Startup (Cold Weather Related)
The driver's instrument cluster remains blank or black at startup, particularly in cold weather or during winter months. The display takes from 30 seconds to 15+ minutes to activate, leaving the driver without critical information including speedometer, warning lights, brake regeneration status, safety diagnostics, and blind spot camera feeds. The issue is intermittent and does not always produce fault codes, making it difficult to diagnose at dealerships. One owner reports the issue worsened over time since summer 2024.
When: At startup, particularly in cold weather; duration can be 30 seconds to 15 minutes; one case noted distance traveled before display energizes is increasing
Symptoms owners cite: Instrument cluster display remains black; No access to speedometer or speed information; No warning lights or safety diagnostics visible; No brake regeneration information displayed; Blind spot camera not visible; Issue worse in cold weather; Using pre-warm climate function before starting resolves issue
Repairs/costs cited: Dealership determined instrument panel replacement needed; book price exceeds $9,000. One owner reports using heads-up display as workaround for speed information.
Recalls/TSBs owners mention: No recall or service bulletin issued despite multiple consumer reports on Genesis forums and Reddit; Genesis has not acknowledged the problem
12-Volt Battery Drain and Loss of Power
The 12-volt auxiliary battery is draining rapidly while driving, with the ICCU failing to properly charge it (voltages dropping from normal 14V when charging to 12.4V and lower). This causes downstream electrical system failure, limp mode, or complete power loss. In one case, the vehicle slowed to 20 mph on a 50 mph road and became undrivable; in another, the vehicle did not accelerate.
When: During normal driving; one case occurred at approximately 24,300 miles
Symptoms owners cite: Excessive battery percentage draining; 12-volt battery voltage dropping (12.4V or lower); Charger port warning light illuminated; Vehicle did not decrease in speed when brake pedal depressed; Vehicle difficult to maneuver; Car slowed to 20 mph and would not accelerate; Check Electric Vehicle System warning; Stop vehicle and check power supply warning
Repairs/costs cited: Vehicle towed; one case not diagnosed or repaired
Recalls/TSBs owners mention: Manufacturer notified in at least one case; no detailed response documented
High-Voltage Fuse Failure
The high-voltage fuse is failing, resulting in loss of electrical power and charging capability. Owners report a loud pop from the vehicle and subsequent loss of all propulsion and charging ability. One case occurred in a garage; another after a recall was completed.
When: Unpredictable; one case within two weeks of completing recall 021G for ICCU software
Symptoms owners cite: Loud audible pop from back seat; Check Electric Vehicle System warning; Stop vehicle and check power supply warning; Loss of propulsion; Vehicle refuses to charge; Charging Unsuccessful message
Repairs/costs cited: Blown fuse diagnosed; vehicle did not charge afterwards
Recalls/TSBs owners mention: Safety recall 021G (ICCU software update) was supposed to prevent fuse failure but did not; TSB recall check available but did not prevent failure

In 2023 & 2025, my vehicle had been brought into the Genesis dealership to complete NHTSA 24V868000 safety recall by receiving a new software (Service Campaigns 907G & 025G). However, despite that, on [XXX], the vehicle's ICCU failed while I was traveling at highway speeds. The ICCU is the primary component that the safety recall was supposed to address, yet it failed anyways. The car suddenly…
Since the weather got colder, the driver's instrument cluster does not display immediately when the vehicle is powered on. When cold, the cluster takes from a few seconds to several minutes to come on. While it is off, there is no access to any warning lights or messages.
When starting the car on cold mornings--parked outside, under a carport--the instrument cluster is blank. It stays blank for two to seven or so minutes, whether or not the car is being driven. This only happens on the cold days, and didn't happen last winter. When the display comes on, it doesn't register the miles that were driven while it was blank. Using the pre-warm climate function before…
Driver’s instrument cluster screen blank at startup every day for several minutes. Without it, the driver can’t see their speed, critical safety warnings, or blind spot cameras. This started in summer 2024 and has gotten worse over time.
The driver instrument cluster is not turning on the startup . Takes several minutes to be turned on.
The contact owns a 2023 Genesis GV60. The contact stated while driving at an undisclosed speed, it was noticed that the battery percentage was excessively draining. The charger port warning light was illuminated. The contact attempted to depress the brake pedal however, the vehicle failed to decrease in speed; the vehicle suddenly became difficult to maneuver. The vehicle was veered onto the…
Sometimes after starting the car the instrument panels remain black and will not display properly for several minutes or unless the car is shutdown for a long period of time and restarted. Additionally, Genesis uses a fingerprint scan to verify who is driving the vehicle. After verifying my fingerprint the vehicle now asks me for a password even though I already verified my biometrics.
At random occurrences during car startup, the instrument cluster remains blank and can take up to several minutes to “wake up”. Since no cluster-related information such as speedometer or safety and diagnostic lights is available at this time, the car remains un-drivable until it eventually resolves. Should it occur while the car is being driven, it can pose a significant safety risk as none of…
This car will simply stop charging after 7 minutes, 10 minutes or one hour. You have to babysit it so it charges.
