Passengers got out of the car and noticed fire under the engine; called 911 immediately, then police and fire engine arrived to extinguish fire. Towed the car to Local Honda Service center. Diagnosis from the service center mentions: "A CONNECTING ROD BROKE AND EXITED THROUGH THE ENGINE BLOCK/OIL PAN AREA ON BACK OF ENGINE. .... and ENGINE ASSEMBLY NEED TO BE REPLACED along with other fire damaged and water damaged parts/sections...."
