2025 KIA EV6 — Complaint #2161251
Open-data reference.
NHTSA Complaint about FUEL/PROPULSION SYSTEM filed December 29, 2025
NHTSA complaint #2161251 (ODI reference 11707594) concerns a 2025 KIA EV6 and was filed on December 29, 2025. The owner reports the failure occurred on December 22, 2025. The report was geocoded to Texas 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 2025 KIA EV6 shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
I was driving on the highway when I heard a pop like a loud fuse sound from the back seat area. Suddenly the car dropped 15 mph from 70 mph to 55 mph and the battery and electrical system warning lights came on and the vehicle said check electrical system. I was able to continue with my hazard lights on to exit the highway, at which point the max speed of the vehicle dropped to 45 mph. It would not go faster no matter how hard I pushed the gas pedal. I was able to pull over to a gas station and park in a spot but the vehicle had to be towed. When the tow truck arrived, the vehicle also flashed with the 12V battery low warning. It was diagnosed as a failed ICCU, which rapidly drained the 12V battery. The car is only 4 months old with about 7,300 miles. This is a serious safety concern, especially with the sudden failure and loss of power. Iâm lucky I wasnât hit and that I was able to get off the road before it totally died.
