NHTSA Complaint #10490106 — 2009 TOYOTA CAMRY

TOYOTA MOTOR CORP. HAS ISSUED SERVICE BULLETIN # T-SB-0094-11 DATED AUG. 11, 2011. THIS SB DESCRIBES THE DIAGNOSIS AND REPAIR OF TOYOTA MOTOR CARS AND TRUCKS USING THE 2AZ-FE 4 CYLINDER ENGINE. THESE ENGINES HAVE A DEFECT RESULTING IN EXCESSIVE OIL CONSUMPTION. EXCESSIVE OIL ENTERING THE COMBUSTION CHAMBER DOES NOT BURN WITH THE FUEL AIR MIXTURE. IT ENTERS THE EXHAUST SYSTEM AS UNBURNED FUEL. IN THE EXHAUST SYSTEM THERE IS A DEVICE CALLED A CATALYTIC CONVERTER. THIS DEVICE HAS A NORMAL INTERNAL OPERATING TEMP. OF 500-1000 DEGREES F. OIL ENTERING THIS DEVICE IS LIKE "POURING OIL ON THE FIRE" WHICH RESULTS IN EXHAUST SYSTEM OVERHEATING ANF FIRE. FURTHER...EXCESSIVE OIL ENTERING THE COMSUMPTION CHAMBER RESULTS IN ENGINE SPARK PLUG FOULING AND MIS-FIRE. ENGINE MIS-FIRE RESULTS IN A MOST VERY SERIOUS CONSEQUENCE...NAMELY...CATALYTIC CONV. OVERHEATING AND FIRE. WHEN A SPARK PLUG FOULS, IT DOES NOT FIRE AND IGNITE THE FUEL AND AIR IN THE CYLINDER. RESULT? RAW FUEL ENTERS THE EXHAUST SYSTEM INCLUDING THE CATALYTIC CONVERTER. NOW YOU ARE "POURING GASOLINE ONTO THE FIRE".I SUGGEST YOU FOLKS INVESTIGATE THIS ENGINE DEFECT, AND DETERMINE IF TOYOTA NEEDS TO RECALL THE VEHICLES HAVING THIS 4 CYLINDER ENGINE. IF THIS EXCESSIVE OIL CONSUMPTION PROBLEM IS NOT ADDRESSED, TO INCLUDE THOSE VEHICLES OUT OF WARRANTY, THERE IS A POTENTIAL FOR LIFE THREATENING UNDER HOOD AND UNDER CAR FIRE TO OCCUR ON THESE HIGH MILEAGE VEHICLES. *TR
