2012 KIA OPTIMA — Complaint #2137973
Open-data reference.
NHTSA Complaint about ENGINE AND ENGINE COOLING filed October 9, 2025
NHTSA complaint #2137973 (ODI reference 11692397) concerns a 2012 KIA OPTIMA and was filed on October 9, 2025. The owner reports the failure occurred on August 7, 2025. The report was geocoded to UN based on the filer's self-reported location. The affected component is categorized as engine and engine cooling, 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: yes, 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 OPTIMA cohort independently describe similar engine and engine cooling 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 2012 KIA OPTIMA shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description

On XXX, my vehicleâs engine failed and caught fire. This is the exact condition covered by the above recalls, which state that affected engines may seize, stall, or ignite. I have been in contact with both a Kia dealership and Kia Consumer Affairs for close to a month without any resolution. The dealership has confirmed that my car requires a complete engine replacement, but Kia has refused to address the recall issue, claiming that other unrelated recalls were not performed. When I previously contacted dealerships to schedule recall repairs, I was told that parts were not available, which prevented me from completing them. In addition to the engine failure, the fire also caused my starter to fail. I was forced to purchase a replacement starter out of pocket, which has added to my financ
