ENGINE

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.

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.

ENGINE

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: 11V539000. HOWEVER, TOYOTA CLAIMS THAT MY VIN NUMBER IS NOT SUBJECT TO THE RECALL. TOYOTA'S RESPONSE TO ME DOES NOT MAKE SENSE SINCE THIS IS THE SAME MODEL, SAME MODEL YEAR, SAME ENGINE MODEL, SAME PARTS MANUFACTURE (PULLEY CONTAINS THE MARK NOTED IN THE RECALL), SAME MANUFACTURE DATE (FEB. 2005), ETC OF THE VEHICLES COVERED BY THE RECALL. SEEMS THAT THE RECALL HAS NOT COVERED ALL OF THE VEHICLES AFFECTED BY THIS FAILURE. MY VEHICLE WAS PURCHASED NEW ON SEPTEMBER 15, 2005.

FIRST, I NOTICED SOME OIL STAINS ON MY DRIVE WAY, THEN I DROVE MY MINIVAN TO A LOCAL TOYOTA CAR DEALER FOR CHECK UP AND ROUTINE OIL CHANGE. NEXT DAY, I NOTICED A BIGGER OIL STAIN. 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. I CALLED TOYOTA CUSTOMER SERVICE, AND THE PERSON WHO ASSISTED ME STATE HIS SURPRISE OF THIS RACK AND PINION LEAKING FOR SUCH A LOW MILEAGE CAR. I WOULD LIKE TO FILE A MECHANICAL DAMAGE REPORT TOWARD TOYOTA DEFECTIVE PARTS.

I WAS DRIVING HOME FROM WORK, AFTER MERGE FROM RTE 20 INTO RTE 9, I DROVE UP HILL, ABOUT 50 YARDS TO MY STREET, I SAW SMOKE BEHIND MY VAN, I DID NOT SEE ANY WARNING LIGHT FROM MY DRIVING PANEL, MY VAN WAS STILL RUNNING SMOOTHLY, SO I DECIDED TO DRIVE TO MY HOUSE (ABOUT 150 YARDS) AWAY, AFTER I PARKED MY VAN, I SAW SMOKE COMING OUT FROM HOOD, AND A LONG LEAKING OIL TRACK ALONG THE STREET. I CHECKED MY ENGINE OIL, IT WAS OK. NEXT MORNING, I STARTED MY VAN, IT IS STILL NO WARNING LIGHT ON MY DRIVING PANEL, I CALLED AAA TO GET MY VAN TOWED TO TOYOTA WESTBOROUGH MA. TECHNICIAN TOLD ME THAT MY ENGINE CYLINDER HEAD GOT BLOWN A HOLE AND OIL FLYING OUT TO BE BURNED AND PRODUCED SMOKE, POTENTIALLY IT WILL CATCH FIRE IF I CONTINUE TO DRIVE. I HAD MY VAN OIL CHANGED ON 08/2012 BY SEARS SHOP, ABOUT 5,000 MILES WAS DRIVEN SINCE LAST OIL CHANGED. I BELIEVE THE ENGINE ALUMINUM HEAD WAS DEFECTIVE PRODUCT, NOT BECAUSE OF OTHER REASON. IT IS VERY DANGEROUS IT HAPPENED WHILE THE VAN WAS RUNNING AT HIGHWAY. IT COULD CATCH FIRE TOO.

ENGINE

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 A HALF BEFORE THEY ISSUED THE RECALL. IF THEY WERE LYING, THEN THE RECALL NEEDS TO BE EXTENDED TO INCLUDE ALL TOYOTA SIENNAS OF THAT YEAR.

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.

ENGINE AND ENGINE COOLING

A/C WENT OUT APRIL 2012. BLOWS HOT AIR. ACCORDING TO ONLINE FORUMS THIS HAPPENS A LOT IN SIENNA'S - 2004 TO 2006 MODELS. WE HAVE 5 CHILDREN IN THE VEHICLE AND CANNOT TAKE THEM VERY FAR EVEN WITH THE WINDOWS DOWN OR THEY COULD POSSIBLY GET HEATSTROKE. THEY ARE SWEATED WET BY THE TIME WE GET FROM POINT A TO POINT B. WE OPEN ALL WINDOWS AND THE REAR ONES THAT ONLY OPEN 2 INCHES AS WELL. FORUM LINK WHERE I FOUND THIS INFO (SAME ISSUE AS OUR SIENNA) IS HTTP://WWW.TOYOTAFANS.NET/2004-SIENNA-AC-PROBLEMS-T2523-ST20.HTM -THE SEAT BELTS IN OUR SIENNA LOCK UP, FOUND THE RECALL ON THIS SITE SO WILL BE TAKING IT TO THE DEALER FOR THAT. NOT JUST THE MIDDLE ROW SEAT BELTS THOUGH. IT IS REAR SEATBELTS AS WELL AS FRONT DRIVER AND PASSENGER SEAT BELTS. -THE TAIL LIGHT WORKS WHEN IT DECIDES TO. SOMETIMES IT IS OFF SO WE GET PULLED OVER - UNTIL THE POLICE OFFICER TAPS IT, AND IT DECIDES TO COME BACK ON. ON A SIDE NOTE - THE LEFT SPEAKER SYSTEM DOES NOT FUNCTION EITHER UNLESS IT WANTS TO. SAME AS THE TAIL LIGHT. ONE MINUTE IT IS OFF (MOST OF THE TIME) AND THE NEXT MINUTE THE SOUND IS BLARING.

THE RADIATOR ON MY 2005 SIENNA DEVELOPED A CRACK ON THE PLASTIC END CAP AT 54,00 MILES. A THREE INCH CRACK. I HAD NO INDICATION OF A PROBLEM DEVELOPING IT HAPPENED QUICKLY AND LEFT MY WIFE STRANDED. I WAS INFORMED BY THE DEALER THAT IT WAS NOT UNDER WARRANTY BECAUSE IT IS NOT PART OF THE DRIVE TRAIN. THEREFORE THE 60,000 MILE WARRANTY DID NOT APPLY. A FRIEND TOLD ME THAT HIS 2005 SIENNA WAS COVERED BY AND EXTENDED WARRANTY BECAUSE TOYOTA IDENTIFIED A PROBLEM WITH RADIATORS CRACKING. I SENT MY COMMENTS/COMPLAINT TO TOYOTA WHO, AS USUAL DENIED MY CLAIM. THEY SAID THE EXTENSION ONLY APPLIED TO 2005 SIENNAS MANUFACTURED BEFORE SEPTEMBER AND GUESS MY TOYOTA WAS MANUFACTURER'S AFTER THAT DATE. I GUESS THEY DID NOT FIX PROBLEM FOR VEHICLES AFTER SEPTEMBER LIKE THEY THOUGHT. I COMPLETED THE REPAIR MYSELF.

ENGINE AND ENGINE COOLING:COOLING SYSTEM

THE A/C IN MY 2005 TOYOTA SIENNA STARTED BLOWING HOT AIR OUT OF THE DRIVER SIDE VENTS. THE COMPRESSOR KEPT KICKING ON AND OFF. THIS OCCURRED EVERYTIME I USED THE A/C. AFTER REPLACING THE COMPRESSOR TWICE, WE STILL HAVE PROBLEMS WITH HOT AIR COMING OUT OF THE VENT WHILE THE A/C IS ON. NOW THE VAN TODAY 4/5/2010 HAS COMPLETELY STOPPED BLOWING COLD AIR AND ONLY BLOWS HOT AIR WHEN THE A/C IS TURNED ON. WE TOOK IT TO THE DEALER AND WERE TOLD THE A/C PULLEY HAS NOT BURNED UP. THERE WAS A TECHNICAL SERVICE BULLETIN ON THIS ISSUE. TOYOTA TECHNICAL SERVICE BULLETIN AC003-05 BUT IT ONLY COVERS VEHICLES UNTIL 36,000. SINCE THE PROBLEM OCCURRED AFTER THAT MILEAGE, WE ARE NOT COVERED. THIS IS THE THIRD MAJOR ISSUE I HAVE HAD WITH THIS 2005 VAN. I HAVE HAD THE BACK DOOR GAS SHOCKS REPLACED UNDER A RECALL AND THE ENTIRE FRONT DRIVER'S DOOR REPLACED UNDER A RECALL. THE FIX FOR THE A/C IS ESTIMATED AT $4,000!
