2005 TOYOTA SIENNA Engine Problems

THE TRACTION CONTROL SYSTEM IS ACTIVATING IMPROPERLY. THE VEHICLE'S ANTI-SLIP INDICATOR WARNING LIGHT ILLUMINATES; AN ALARM SOUNDS; THE ABS SYSTEM ACTIVATES; AND THE VEHICLE SOMETIMES LOSES POWER. THIS HAPPENS ON DRY ROADS, MOST COMMONLY EITHER GOING DOWNHILL OR ELSE ON A CURVE, EVEN A MILD ONE. THIS HAPPENS ABOVE 20 MPH. WHEN IT HAPPENS, THE COMBINATION OF ALERTS AND SENSATIONS ARE VERY STARTLING TO THE DRIVER, CREATING A DANGEROUS SITUATION. IT HAS OCCURRED WHILE TRYING TO ACCELERATE TO MERGE ONTO A HIGHWAY. THIS WAS EXCEPTIONALLY DANGEROUS AS THE VEHICLE BEGAN LOSING POWER AND VEHICLES BEHIND US ALMOST HIT US FROM BEHIND AS WE WERE SLOWING INSTEAD OF INCREASING SPEED. FROM MY INTERNET SEARCHES (INCLUDING NHTSA COMPLAINTS), THIS APPEARS TO BE A RECURRING ISSUE WITH THIS MAKE/MODEL/YEAR RANGE. THIS HAS BEEN HAPPENING FOR THE PAST 3 MONTHS. OUR VEHICLE HAS APPROXIMATELY 135,000 MILES ON THE ODOMETER.

MY CAR HAS THE EXACT SYMPTOMS FOR A RECALL INVOLVING A CRANKSHAFT PULLEY, YET MY VIN IS APPARENTLY NOT INVOLVED WITH THAT RECALL. MY ENGINE MODEL 3MZ-FE IS INVOLVED WITH THE RECALL YET TOYOTA SERVICE DEALERSHIPS AND TOYOTA CUSTOMER EXPERIENCE BOTH SAY IT ISN'T. CURRENTLY MY CAR IS NOT SAFE TO DRIVE ACCORDING TO THE SERVICE DEALERSHIP AND A FEE OF ROUGHLY $800 AWAITS ME. I DO NOT UNDERSTAND HOW MY MAKE, MODEL, MODEL YEAR, ENGINE MODEL, CAN ALL BE RELATED TO A CERTAIN RECALL, AND YET BE TOLD THAT MY CAR DOES NOT QUALIFY FOR THAT RECALL. I'VE BEEN A LOYAL TOYOTA CUSTOMER FOR YEARS RECOMMENDING FRIENDS AND FAMILY. EXTREMELY DISAPPOINTED, AND MOST LIKELY WON'T PURCHASE ANOTHER TOYOTA.

~2007, RADIATOR LEAK, ENGINE HEATED UP - ALMOST FIRE ~2008, RADIATOR LEAK, ENGINE HEATED UP - ALMOST FIRE ~2011, RADIATOR LEAK, ENGINE HEATED UP ~2014, RADIATOR LEAK RADIATOR FAILURE HAS OCCURRED FOR EVERY TWO YEARS. ALMOST IN FIRE FOR MULTIPLE TIMES! DRIVER IS CONSTANTLY UNDER DANGER OF FIRE. TOYOTA CUSTOMER SERVICE RESPONDED BY OFFERING A $200-300 CREDIT, SUGGESTING TOYOTA KNOWS THERE IS SOMETHING WRONG FOR SUCH FREQUENT RADIATOR LEAKING. BUT IT REFUSES TO DISCLOSE DETAILS. FOR THE SAFETY OF DRIVERS, PLEASE INVESTIGATE. INDIVIDUAL DRIVER LIKE MYSELF IS TOO SMALL TO TALK TO TOYOTA. TOYOTA EVEN DID NOT ANSWER MY QUESTION.

WHILE DRIVING ON 4 LANE HIGHWAY, I BEGAN TO SMELL BURNING RUBBER, THEN NOTICED THAT THE BATTERY DISCHARGE INDICATOR LIGHT CAME ON. FOUND THAT THE SERPENTINE BELT DRIVING THE ALTERNATOR AND COMPRESSOR HAD BEEN SHREDDED AND WAS HANGING TO THE GROUND. UPON A CLOSER LOOK, THE CRANKSHAFT PULLEY HAD FAILED (IT HAD COME APART). IT APPEARED THAT THE OUTER RING HAD SEPARATED FROM THE RUBBER INNER RING OF THE PULLEY AND THE OUTER RING HAD BECOME MISALIGNED. THE MISALIGNMENT APPEARED TO HAVE CAUSED THE SERPENTINE BELT FAILURE. IT ALSO CAUSED DAMAGE TO THE TIMING BELT COVER, THE TIMING BELT AND THE POWER STEERING BELT. THE BATTERY LIGHT CAME ON BECAUSE OF THE FAILED SERPENTINE BELT. FORTUNATELY, I MAINTAINED POWER STEERING BECAUSE THE POWER STEERING BELT HAD NOT COMPLETELY FAILED WHEN I PULLED OFF THE HIGHWAY. THE FAILURE SEEMS TO BE IDENTICAL TO THAT COVERED BY SAFETY RECALL NHTSA CAMPAIGN NUMBER:...

ANYWAY, I HAD AN APPOINTMENT AND HAVE TO DRIVE MY MINIVAN TO MY DENTIST OFFICE, ON THE HIGHWAY, I SAW SMOKE CAME OUT OF MY FRONT HOOD. THEN, I DROVE IT TO THE SAME TOYOTA DEALER AFTERWARDS. IT WAS QUITE SCARY DRIVING AND SEEING SMOKE CAME OUT OF MY FRONT HOOD ESPECIALLY WITH MY YOUNG DAUGHTER ON BOARD TODAY. AT ONE MOMENT, I THOUGHT MY CAR WILL BE ON FIRE. ON THE PAPER, I WAS TOLD THAT MY LEAKING IS FROM RACK AND PINION STEERING SYSTEM.

UNDER TOYOTA'S CUSTOMER SUPPORT PROGRAM, A TECHNICAL SERVICE BULLETIN WAS PUT OUT SAYING THAT 2005 TOYOTA SIENNAS HAD FAULTY RADIATORS THAT CRACKED IN COLD WEATHER AND COULD LEAD TO COOLANT LEAKAGE AND SUBSEQUENT ENGINE SEIZURE (SAFETY REPORT #0506). WHEN THE WEATHER STARTED GETTING COLD THIS WINTER, MY RADIATOR CRACKED AND I NEEDED TO BE REPAIRED AS THE ENGINE WAS RUNNING EXTREMELY HOT. WHEN I FOUND THIS BULLETIN AND BROUGHT IT TO TOYOTA'S ATTENTION THEY REFUSED TO HONOR IT SAYING THAT MY VIN NUMBER WAS NOT IN THE RANGE. WHEN I ASKED WHY THIS WAS THE CASE, THEY CLAIMED (THEY BEING TOYOTA'S NATIONAL HEADQUARTERS) THAT THEY HAD REALIZED THE FAULT AND THEREFORE SWITCHED THE RADIATORS OUT DURING PRODUCTION. UPON CLOSER EXAMINATION, THE BULLETIN WAS ANNOUNCED BY TOYOTA ON JANUARY 30, 2006. IF WHAT THEY CLAIM IS TRUE, THEN THEY WERE KNOWINGLY SELLING CARS WITH FAULTY RADIATORS FOR ABOUT A YEAR AND...

DURING INSPECTION AND REPAIR OF OTHER VEHICLE RECALLS, IT WAS DETERMINED THAT POWER STEERING ASSEMBLY WAS SEVERELY LEAKING FLUIDS, THAT RADIATOR WAS LEAKING IN 3 PLACES, AND AIR CONDITIONING COILS HOSES\BRACKETS WERE CORRODED AND CRACKED DUE TO MANUFACTURER USING TWO DISSIMILAR METALS (SUCH AS STEEL BOLTS IN ALUMINUM ASSEMBLY) AND THEREBY REQUIRING IMMEDIATE REPLACEMENT FOR SAFETY. TOYOTA DEALERSHIP UPON INSPECTION DECLARED STEERING ASSEMBLY A "CRITICAL" REPAIR AND ISSUED WRITTEN DOCUMENTATION. I TOOK VEHICLE TO ANOTHER SHOP AND THEY CONFIRMED TOYOTA'S DEALERS CONCLUSION AND ALSO FOUND RADIATOR AND CONDITIONING COILS PROBLEMS MISSED BY DEALER. ALL PROBLEMS HAVE BEEN FIXED AT OWNERS EXPENSE - A RECALL SHOULD BE MADE BY MANUFACTURER. *TR
