Problem overview

Some Kia Optima owners report experiencing stalling and loss of power accompanied by a burning smell prior to failure. These issues may stem from common causes such as fuel system problems and ignition failures, or even fuel quality issues like bad gas or water in the tank. Additionally, loss of power can indicate engine issues, transmission problems, or electrical malfunctions. The presence of a burning smell, particularly if accompanied by a squeal, may suggest overheating or belt issues. Owners have also noted signs of electrical system malfunctions, such as multiple blown fuses and intermittent failures of electrical components. Furthermore, stalling and loss of power might trigger warning lights on the dashboard, including the check engine light, coolant light, battery light, and oil light. It is crucial for owners to address these symptoms promptly to avoid further damage and maintain the reliability of their Kia Optima. Consulting a qualified mechanic for inspection and diagnosis is highly recommended.
