TL*THE CONTACT OWNS A 2006 FORD EXPEDITION. WHILE DRIVING 20 MPH, THE VEHICLE STALLED. THE ENGINE WARNING LIGHT ILLUMINATED ON THE INSTRUMENT PANEL AND READ, "ENGINE FAIL SAFE MODE." AFTER SEVERAL ATTEMPTS, THE CONTACT WAS ABLE TO RESTART THE VEHICLE. THE DEALER REPLACED THE THROTTLE BODY ASSEMBLY. AFTER THE REPAIR, THE CONTACT BEGAN SMELLING A BURNING OIL ODOR IN THE VEHICLE. THE SMELL BECAME STRONGER AND THEN TURNED INTO A GASEOUS ODOR, WHICH WAS ALSO ENTERING THROUGH THE INTERIOR VENTS. THE CONTACT INSPECTED THE VEHICLE, BUT COULD NOT LOCATE ANY GAS LEAK. THE ODOR BECAME SO OVERPOWERING THAT ONE OF THE OCCUPANTS HAD A NOSE BLEED AND SEVERAL OTHER OCCUPANTS SUFFERED HEADACHES AND STOMACH ACHES.
