Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical on this vehicle — documented
repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall
(it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
Warranty ProgramZ14 OLJun 2026
Certain 2022 – 2024 model year IONIQ 5, 2024 model year IONIQ 5 Robotaxi, and 2023 – 2025 model year IONIQ 6 vehicles may require a replacement of the Integrated Charging Control Unit (ICCU) and ICCU Fuse. At Hyundai, we are committed to providing vehicles of outstanding quality and value. In an effort to meet this commitment, the warranty coverage for the Integrated Charging Control Unit (ICCU) and ICCU Fuse Replacement has been extended to 15 years/ 180,000 miles from the date of original retail delivery or date of first use (whichever occurs first) and is valid for original and subsequent owners.
This bulletin provides information related to the navigation and head unit software changes introduced in the 2026 1st Navigation Map and Software Update. The changes may vary depending on vehicle type, model, and navigation system. Refer to the 2026 1st Navigation Map and Software Update Key Improvements and Additional Improvements tables in this TSB for a list of specific changes. The software can be downloaded via Navigation Updater (NAU) and updated by USB.

The failure pattern owners describe
The dominant complaint across these 15 narratives is ICCU failure—sudden, catastrophic loss of electrical power while driving or at a standstill. Owners describe hearing a pop, seeing warnings like "Check Electric Vehicle System" or "Stop vehicle and check power supply," then losing the ability to accelerate beyond 15–40 mph. One driver on a freeway at 60 mph felt the car nearly stall; another lost power while climbing a hill with traffic behind. A third was stranded at a DC charging station unable to restart despite an error claiming the charger was still plugged in.
The pattern is consistent: no warning beforehand, sudden failure, severe limp mode or shutdown. Owners note that some vehicles received the Recall 272 software update and ICCU replacement in November 2024 but failed again months later—one by January 2026. Dealership diagnostics confirm ICCU failure. The replacement parts are the same design and fail identically, leaving owners with no confidence the fix is permanent.
Parts are on indefinite backorder. Vehicles are sitting at dealerships for three weeks, four weeks, or longer with no ETA. One owner is making monthly lease payments on a car she cannot drive. Another waited in a winter storm on the roadside for a tow truck after the ICCU cut power in dangerous conditions.
A small number of reports cite 12-volt system failures or charging-related issues as precursors or concurrent problems. One unintended acceleration incident at 3 mph resulted in collision with a house, but was never diagnosed.

Failure modes owners describe
ICCU (Integrated Charging Control Unit) Failure
The ICCU, a critical electrical component, fails suddenly without warning, causing immediate loss of vehicle propulsion and power. Failures occur with minimal warning—sometimes just a dashboard alert moments before total shutdown. The ICCU controls charging and power distribution; when it fails, the vehicle cannot accelerate above 15–25 mph initially, then enters severe limp mode or complete shutdown. The part requires replacement; Hyundai has issued a recall (Recall 272 for 2023–25 Ioniq 6) that included a software update, but owners report the update has not prevented subsequent failures. Replacement ICCUs are the same design and also fail, indicating the root cause remains unaddressed. Parts are on indefinite backorder with no ETA, leaving vehicles at dealerships for weeks or longer.
When: Occurs across vehicle ages from 300 miles to 14,794 miles and beyond. No consistent pattern; happens at startup, during highway driving, or while charging.
Symptoms owners cite: Sudden loss of power while driving (60 mph, uphill, or during acceleration); Dashboard warnings: 'Electrical System issue,' 'Check Electric Vehicle System,' 'Stop vehicle and check power supply,' '12-Volt System Deactivated,' 'Please unplug the charger to start the car' (false message when not plugged in); Vehicle speed limited to 15–40 mph initially, then progressive limp mode or complete shutdown; Audible pop from rear/under vehicle at moment of failure; 12-volt accessory battery stops charging; Vehicle will not accelerate past limp-mode speeds even with heavy throttle input; Vehicle loses ability to charge from home charger
Codes mentioned:P1A9096
Repairs/costs cited: ICCU replacement required; fuse replacement often required simultaneously. Owners report replacement ICCU is same design and prone to same failure. Parts availability severely delayed; some vehicles waiting 3+ weeks at dealership with no ETA on parts.
Recalls/TSBs owners mention: Recall 272 (2023–25 MY Ioniq 6, 2022–24 MY Ioniq 5): software update and ICCU & fuse replacement. However, owners report the recall was not always completed before vehicle delivery, and the software-only fix did not prevent subsequent failures in the same vehicles. Replacement ICCUs are identical design.
Charging System Degradation Preceding ICCU Failure
In at least one case, DC fast-charging performance degraded over time before the ICCU failed completely. Charging time for reaching 80% battery capacity increased from 15 minutes to 20–30 minutes over roughly two months (November 2025 to January 2026). Vehicle then became inoperable at the charging station with a false 'unplug charger' message while already unplugged.
When: November 2025 to January 2, 2026 (on a vehicle leased in April 2025)
Symptoms owners cite: DC fast-charging (L3) speed drops: 15 minutes → 80% baseline becomes 20–30 minutes; Vehicle stranded at charging station with inoperable state; False error message: 'Please unplug the charger to start the car' when charger was not connected; Battery drained even while vehicle sat inoperable and not running
Repairs/costs cited: Vehicle towed to dealership and remained there over a week with battery draining. Not yet repaired at time of complaint.
Recalls/TSBs owners mention: Open recall on ICCU noted by owner on Hyundai website; however, no record that recall was completed before lease start in April 2025.
Unintended Acceleration at Low Speed
One report of unintended acceleration while reversing at approximately 3 mph, resulting in front-end collision with a house. Vehicle was not diagnosed or repaired. This is a single incident in the complaint set; it occurred at very low mileage (6,112 miles) with no confirmation of root cause. Electrical system failure could be involved, but the narrative does not specify ICCU or other electrical diagnostics.
When: At 6,112 miles
Symptoms owners cite: Vehicle inadvertently accelerated while reversing into driveway at ~3 mph; Vehicle struck the side of a house; Damage to front bumper and house
Repairs/costs cited: Vehicle not taken to dealer, not diagnosed, not repaired.
12-Volt Battery or Computer Module Failure (Possible Charger-Related)
One owner reported a computer control module failure triggered by using a faulty phone charger inside the vehicle. Vehicle stalled at very low mileage (300 miles) with a '12-Volt System Deactivated' message. The module was replaced and vehicle was repaired. This appears to be a separate root cause from the main ICCU failures but shares the symptom of sudden loss of propulsion.
When: At 300 miles
Symptoms owners cite: Vehicle stalled while reversing out of garage; Dashboard message: '12-Volt System Deactivated'; Loss of vehicle operation
Repairs/costs cited: Computer control module replaced. Owner reported root cause as faulty phone charger used inside vehicle.
Recalls/TSBs owners mention: Manufacturer was notified of failure.
