VEHICLE WAS IN MOTION TURNING RIGHT DECELERATING AS I TURNED. ONCE I TURNED, ACCELERATION PEDAL WAS DISENGAGED AND NO ACCELERATION WAS HAPPENING. BRAKING SYSTEM WAS COMPLETELY LOCKED UP AND COULD NOT PRESS THE BRAKES. WHEN I COASTED TO A STOP, THERE WAS VISIBLE FIRE COMING FROM UNDERNEATH THE ENGINE COMPARTMENT. TEMP GAGE NEVER REGISTERED AS HIGH WHILE DRIVING. WITHIN A MATTER OF A COUPLE MINUTES, THE WHOLE CAR WAS ENGULFED IN FLAMES AS I WAITED FOR THE FIRE DEPARTMENT TO ARRIVE. THEY SAID THERE WAS NO VISIBLE FLUID LEAKING ON THE GROUND AND DID NOT KNOW THE CAUSE OF THE FIRE. CAR WAS MAINTAINED REGULARLY FOR OIL. HAD ISSUES WITH THE CAR OVERHEATING AND TOOK IT TO KIA AND THEY COULD NOT FIND ANYTHING WRONG WITH IT AND RELEASED ME. CAR IS TOTALED NOW.
