NHTSA Complaint #11682620 — 2015 KIA OPTIMA

The vehicle unexpectedly stalled while idling at a complete stop, posing a serious safety concern. Shortly afterward, the check engine light illuminated. These events occurred around 78,000 miles. Prior to the stall, the engine had been making occasional knocking or tapping noises, particularly at idle. The vehicle was immediately taken to a certified Kia dealership, where a technician diagnosed the issue as engine failure consistent with a known manufacturer recall affecting this vehicle model and year. A recall claim was submitted to the manufacturer, but the repair has been delayed for over a month with no authorization to proceed. No loaner vehicle has been provided. The engine failure puts the driver and others at risk, especially if the vehicle were to stall during active traffic conditions. The problem has been confirmed by the dealership but has not yet been resolved by the manufacturer. Inspection by the manufacturer is still pending. Warning symptoms included the engine light and knocking sounds, which began shortly before the stall occurred.
