NHTSA complaint #2174272 (ODI reference 11716251) concerns a 2025 KIA K4 and was filed on February 6, 2026. The owner reports the failure occurred on October 24, 2025. The report was geocoded to Texas based on the filer's self-reported location. The affected component is categorized as back over prevention: rearview system braking, 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: yes, fire: no, injuries: 0, fatalities: 0. A complaint that flags a crash, fire, or fatality is escalated on NHTSA's internal review queue and factors more heavily into any Preliminary Evaluation decision on this make and model. 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 K4 cohort independently describe similar back over prevention: rearview system braking failures, defect investigators have grounds to open a PE and request manufacturer data.
