I received a recall notice for my 2013 Kia Optima, VIN #: [redacted] related to engine issues and an increased risk of fire. After receiving the recall notice, my vehicle began smoking and briefly caught fire while in operation. I immediately shut the vehicle off, and the smoke and fire stopped. For safety reasons, the vehicle was towed by my insurance company to my aunt's residence, which was the closest safe location at the time. The vehicle was unsafe to drive. No injuries occurred, and the fire department was not called because the fire stopped once the vehicle was turned off. I believe this incident is related to a known safety defect and recall involving Kia Optima engine fires. I have contacted Kia multiple times regarding this issue, and there have been delays in addressing or repairing the vehicle.
