2025 HYUNDAI IONIQ 5 — Complaint #2178590
Open-data reference.
NHTSA Complaint about ELECTRICAL SYSTEM filed February 19, 2026
NHTSA complaint #2178590 (ODI reference 11719145) concerns a 2025 HYUNDAI IONIQ 5 and was filed on February 19, 2026. The owner reports the failure occurred on February 12, 2026. The vehicle had 8,000 miles on the odometer at the time of the incident. The report was geocoded to California based on the filer's self-reported location. The affected component is categorized as electrical system, one of NHTSA's standardized taxonomy codes used to group defect patterns across make, model, and year.
The filer flagged the following severity indicators: crash: no, fire: no, injuries: 0, fatalities: 0. No crash, fire, or fatality was associated with this report, which places it in the early-warning stream rather than the priority-review stream. Because a VIN was supplied, this complaint is tied to a specific vehicle and not just a model-year cohort.
Individual complaints are consumer-submitted and unverified by NHTSA engineers — the agency's role at this stage is to collect, index, and make them searchable. What matters for federal action is the pattern: when many owners of the same HYUNDAI IONIQ 5 cohort independently describe similar electrical system failures, defect investigators have grounds to open a PE and request manufacturer data. Related filings for the same vehicle and component appear below, and the detail page for the full 2025 HYUNDAI IONIQ 5 shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
The contact owns a 2025 Hyundai Ioniq 5. The contact stated that after starting the vehicle, the battery warning light remained illuminated, and the vehicle failed to exceed 45 MPH while driving. The messages "Onboard Charger - Stop Vehicle" and "Power Supply" were displayed. The vehicle was later towed to the local dealer who diagnosed that the ICCU Module had failed and needed to be replaced. The vehicle was not yet repaired. The contact stated that during the failure, the electric battery had failed to recharge the 12-Volt battery as intended, which caused the failure. The manufacturer was notified of the failure and informed the contact that the vehicle was not included in NHTSA Campaign Number: 24V868000 (ELECTRICAL SYSTEM). The contact stated that the vehicle had experienced the failure listed in the recall. The failure mileage was 8,000.
