Open-data reference.
NHTSA Complaint about FUEL/PROPULSION SYSTEM filed February 19, 2026
NHTSA complaint #2178522 (ODI reference 11719101) concerns a 2024 KIA EV6 and was filed on February 19, 2026. The owner reports the failure occurred on February 19, 2026. The report was geocoded to California based on the filer's self-reported location. The affected component is categorized as fuel/propulsion 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 KIA EV6 cohort independently describe similar fuel/propulsion 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 2024 KIA EV6 shows the complete component-level complaint distribution alongside any active investigations or recalls.

ICCU failure while driving. Vehicle defaulted into limp-home mode and required towing to a dealership once it fully died. The issue was confirmed to be the ICCU and the part was replaced.
Car suddenly slowed from 55 mph to 25 mph because of issues with the 12v battery and the ICCU system. The car is only 1 year old. From looking online, this seems to be a fairly common issue/problem.
Heard a pop, followed by power failure and warning lights to stop operating the vehicle. The ICCU unit had blown.
