2004 Toyota Sienna engine and engine cooling problems

“The contact's mother owns a 2004 Toyota Sienna. While the contact's mother was driving at an undisclosed speed, several unknown warning lights illuminated. The contact stated that the warning lights illuminated on and off for days and months. The vehicle was taken to an independent mechanic where DTC: P2241 was retrieved. The vehicle was not repaired. The contact was advised to take the vehicle to the dealer. The vehicle was taken to the dealer where the failure code was confirmed. The contact was informed that the oxygen sensors needed to be replaced. In addition, the contact was informed that a TSB for the ECM software update needed to be performed. The contact stated that the vehicle was not repaired because the ECM software update was performed, and the ECM software update damaged the ECM. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 150,132.”

“TL* THE CONTACT OWNS A 2004 TOYOTA SIENNA. WHILE DRIVING APPROXIMATELY 55 MPH, THE CONTACT HEARD A LOUD NOISE AND LOST STEERING CONTROL. THE VEHICLE WAS PULLED OVER TO THE SIDE OF THE ROAD AND TOWED TO THE CONTACT'S RESIDENCE. THE VEHICLE WAS LATER TAKEN TO AN INDEPENDENT MECHANIC WHERE IT WAS DIAGNOSED THAT THE CRANKSHAFT PULLEY FAILED AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 96,321.”

“FAN BELT STARTED SQUEALING UPON ENGINE START, TOOK TO DEALER AND REPLACED SERPENTINE BELT. SEVERAL MONTHS LATER GROANING NOISE STARTED COMING FROM ENGINE, SUSPECTED MISALIGNED BELT OR BAD PULLEY. TOOK VEHICLE TO THE DEALER AND THEY FOUND WEAR ON THE EXTERIOR OF THE TIMING BELT COVER CAUSED BY THE PARTIAL SEPARATION OF THE CRANKSHAFT PULLEY. SEVERAL REPORTS ONLINE OF OWNERS EXPERIENCING THIS PROBLEM WITH TOYOTAS. CHECKED WITH DEALER AND TOYOTA CUSTOMER SERVICE AND THEY CLAIM MY VIN IS NOT COVERED BY THE RECALL THEY ISSUED IN 2011 FOR THE VERY SAME FAILURE I AM EXPERIENCING (11V539000). HOW IS IT POSSIBLE THAT A KNOWN DEFECT IN THEIR VEHICLES CAN BE EXCLUDED BECAUSE THEIR EXPERTS HAVE MADE THE DETERMINATION THAT THE "CAUSE" WAS A PROBLEM AT ONE FACTORY OR PART SUPPLIER WHEN OTHER OWNERS THAT DON'T FALL INTO THE SPECIFIC PARAMETERS HAVE HAD THE VERY SAME PROBLEM AND WERE FORCED TO PAY FOR REPAIRS OUT OF POCKET? *TR”

“THERE IS A CRACK IN MY TOYOTA SIENNA 2004 RADIATOR AND THE COOLANT IS LEAKING. I RECEIVED A LETTER FROM TOYOTA WITH INFORMATION THAT THEY HAD RECEIVED REPORTS OF CRACKS IN RADIATORS IN 2004 AND 2005 TOYOTA SIENNAS. AS A RESULT OF THESE REPORTS TOYOTA WAS EXTENDING THE WARRANTY ON THESE RADIATORS TO 6 YEARS OR 72,000 MILES FROM THE IN-SERVICE DATE. SINCE I NOTICED THE CRACK IN THE RADIATOR IN MY 2004 TOYOTA SIENNA WHEN IT HAD 85,000 MILES, TOYOTA HAS REFUSED TO PAY EVEN A % OF THE COST OF REPLACING THE RADIATOR. I BOUGHT THE TOYOTA SIENNA AND PAID THE HIGHER PRICE BECAUSE OF TOYOTA'S REPUTATION FOR USING VERY HIGH QUALITY PARTS IN ITS CARS. I PREVIOUSLY OWNED A TOYOTA CAMRY AND HAD ALMOST 200,000 MILES ON IT. I DID NOT HAVE ANY PROBLEMS WITH THE RADIATOR IN MY TOYOTA CAMRY. I CALLED TOYOTA'S CUSTOMER SERVICE DEPARTMENT ABOUT THIS PROBLEM AND THEY REFUSED TO DO ANYTHING ABOUT IT, SAYING THAT THE CAR IS OUT OF THE WARRANTY PERIOD SINCE IT HAS 85,000 MILES. CLEARLY, THE CRACK IN MY 2004 TOYOTA SIENNA IS DIRECTLY DUE TO THE DEFECTIVE RADIATOR. SO MANY 2004 AND 2005 TOYOTA OWNERS ARE HAVING PROBLEMS OF CRACKED RADIATORS AFTER THE EXPIRATION OF THE EXTENDED WARRANTY…”

“THIS IS A COMPLAINT, NOT NECESSARILY A SAFETY ONE, BUT A COMPLAINT NONETHELESS. THE AIR CONDITIONING WENT OUT TWICE & HAD TO BE REPLACED TWO TIMES. VERY EXPENSIVE REPAIR. DISAPPOINTED IN MY TOYOTA. *TR”

“WHILE DRIVING THERE WAS A VERY LOUD SCREECH FROM THE MOTOR, ON AND OFF, THEN THE POWER STEERING WENT OUT, VERY HARD TO TURN STEERING WHEEL, LUCKILY I WAS ABLE TO FORCE IT THE FEW MILES LEFT HOME. THEN I NOTICED THE A/C WAS NOT COLD, THIS WAS INTERMITTENT, NOW, NO A/C AT ALL. JUST HOT AIR. THIS STALLED OF FAILED WHILE IN TRAFFIC, I COULD HAVE HAD SERIOUS PROBLEMS LIKE GETTING HIT BECAUSE I COULD NOT TURN THE VEHICLE READILY, OR EASILY. *TR”
