2004 Toyota Sienna Engine Problems

Your warning lights have been turning on and off intermittently for days or months. A mechanic found error code P2241, which indicates your oxygen sensors need replacement. The dealer also performed an ECM software update, but that update damaged your engine control module instead of fixing the problem. You'll likely need new oxygen sensors and possibly an ECM replacement or reprogramming to resolve this issue.

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 PERIOD OF 6 YEARS OR 72,000 MILES. THE ARBITRARY EXTENDED WARRANTY PERIOD OF 6 YEARS AND 72,000 MILES DOES NOT PROTECT THE TOYOTA SIENNA OWNERS FROM THE DEFECTIVE RADIATOR BECAUSE IN MOST CASES THE RADIATOR WILL CRACK JUST AFTER THE EXTENDED WARRANTY HAS EXPIRED. TOYOTA SHOULD TAKE RESPONSIBILITY FOR USING A DEFECTIVE RADIATOR AND AT LEAST REIMBURSE OWNERS 50% TO 70% OF THE COST OF REPLACING THE DEFECTIVE RADIATOR WHEN IT CRACKS AFTER 72,000 MILES. *TR

TL* THE CONTACT OWNS A 2004 TOYOTA SIENNA. THE CONTACT STATED THAT WHILE STARTING THE ENGINE, HE NOTICED AN ABNORMAL SQUEAKING NOISE. THE VEHICLE WAS TAKEN TO THE DEALER FOR DIAGNOSIS. THE TECHNICIAN STATED THAT THE CRANK SHAFT PULLEY HAD DETACHED FROM THE VEHICLE. THE CONTACT REFERENCED NHTSA CAMPAIGN NUMBER: 11V539000 (ENGINE AND ENGINE COOLING) BUT WASW ADVISED BY THE MANUFACTURER THAT THE VIN WAS NOT INCLUDED IN THE RECALL. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 110,000.

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

TL* THE CONTACT OWNS A 2004 TOYOTA SIENNA. THE CONTACT STATED THAT THERE WAS A SIGNIFICANT AMOUNT OF ANTI FREEZE MISSING FROM THE RADIATOR RESERVOIR. THE VEHICLE WAS NOT REPAIRED AND THE MANUFACTURER WAS NOT NOTIFIED. THE APPROXIMATE FAILURE MILEAGE WAS 166,000. *TR

I WAS DRIVING MY VAN WHEN I NOTICED THE A/C WAS NOT BLOWING COLD AIR, IT WAS MORE COOL THAN COLD. THEN IT WOULD BLOW HOT AIR ON OCCASION THEN IT WOULD EVENTUALLY BLOW COLD AIR AGAIN. EVENTUALLY THE AIR WASNT COLD AT ALL AND IT WOULD CONSTANTLY BLOW HOT AIR. THIS WAS VERY UNCONFORTABLE DUE TO THE FACT THAT IT WAS SUMMER AND I LIVE IN FLORIDA. I TOOK IT TO A MECHANIC AND HE TOLD ME IT WAS THE COMPRESSOR, SO I HAD IT REPLACED. THE AC WAS BLOWING COLD AGAIN, THIS LASTED FOR ABOUT 12 MONTHS. THE SAME ISSUE STARTED TO HAPPEN AGAIN. FIRST COOL AIR THEN ON AND OFF HOT AIR AND NOW NOTHING BUT HOT AIR. I TOOK IT BACK TO MY MECHANIC AND HE TOLD ME IT MIGHT BE THE RELAYS, I REPLACED BOTH OF THE RELAYS AND THE AIR IS STILL NOT COLD. I THEN FOUND OUT THAT IT WAS THE COMPRESSOR AGAIN. I CANNOT AFFORD TO REPLACE THE COMPRESSOR AND IM AFRAID TO REPLACE IT IF THE PROBLEM WILL JUST CONTINUE. I FEEL A RECALL FOR THE FAULTY PART IS IN STORE. I AM AWARE THE VEHICLE ITSELF IS A FEW YEARS OLD BUT MY OTHER VEHICLE IS A 99 AND I HAVE NO PROBLEMS WITH THE AC OTHER THAN I HAVE TO TURN IT OFF AT TIMES BECAUSE ITS TOO COLD. IVE GONE TO ONLINE FORUMS AND READ UP ON THE 2004 TOYOTA SIENNAS AND FOUND OUT THAT I AM NOT THE ONLY ONE WITH AN AC PROBLEM. THIS PROBLEM IS WITH MANY MORE VANS. *TR

RADIATOR LEAK, CONTINUOUS PROBLEM. COULD CAUSE CATASTROPHIC ENGINE FAILURE. TOYOTA WILL NOT ADDRESS REPAIR. *TR UPDATED 3/01/2012 *LN

MY 2004 SIENNA HAS LEAK IN WATER PUMP WITH 66K MILE. *TR

2004 TOYOTA SIENNA - AIR CONDITIONING COMPRESSOR BLOWS CAUSING ALARMING NOISES WHILE DRIVING. *TR

A/C WENT OUT AT 70K FOR MY 2004 TOYOTA SIENNA. NEVER HAD A PROBLEM UNTIL NOW OVER $3000 TO FIX. *TR

I HAVE 2 DIFFERENT COMPLAINTS. DRIVER SIDE SEAT HEATER BURNED LEGS OF 3 DIFFERENT DRIVERS BEFORE COMPLETE FAILURE. HEAT WAS NOT ADJUSTABLE. DRIVER AND PASSENGER HEATERS STOPPED WORKING AT SAME TIME. TOOK TO DEALER, RECOMMENDED NEW HEATING ELEMENT ($1000+). OPTED NOT TO FIX. 2ND COMPLAINT, CHECK ENGINE, VSC, AND TRAC OFF LIGHTS ILLUMINATED. THE VAN HAS BEEN SENT TO THE DEALER ON AT LEAST 3 OCCASIONS. GAS CAP HAS BEEN REPLACED SEVERAL TIMES, SPARK PLUGS CHANGED. WILL GO OFF FOR BRIEF PERIODS, BUT ALWAYS TO RETURN. THIS HAS BEEN GOING ON FOR AT LEAST 30,000 MILES. I COULD LIVE WITH THE CHECK ENGINE LIGHT ON, BUT IF THE OTHER LIGHTS ARE ILLUMINATED, THAT INDICATES THESE COMPONENTS ARE NOT WORKING-KIND OF IMPORTANT-SKID CONTROL & TRACTION CONTROL!! THERE ARE MANY COMPLAINTS OUT THERE ON BLOGS, DOESN'T LOOK LIKE ANYONE HAS FILED ANY REPORTS WITH YOUR OFFICE REGARDING THIS SAME PROBLEM, WHICH IS TOO BAD BECAUSE IT'S OBVIOUSLY A PROBLEM NOT WITH JUST SIENNA BUT SEVERAL OTHER MODELS AS WELL. EXTREMELY FRUSTRATING WHEN EVEN THE DEALER CAN'T DETERMINE WHAT THE PROBLEM REALLY IS!! WE PURCHASED THIS VEHICLE BECAUSE OF THE SAFETY FEATURES. NOT SO SURE ABOUT IT IF THEIR SAFETY FEATURES MALFUNCTION! *TR

2004 TOYOTA SIENNA. ORIGINAL RADIATOR REPLACED DUE TO LEAK @ 21K MILES. RADIATOR REPLACED A SECOND TIME DUE TO LEAKS AT TOP L & R SIDES, NEAR END TANKS @ 80K MILES. RADIATOR IS NOW IN NEED OF ANOTHER REPLACEMENT @130K MILES DUE TO LEAKS AT THE SAME LOCATION. ALL RADIATORS HAVE BEEN REPLACED BY TOYOTA DEALER. *TR

THE SLIDING AUTOMATIC DOOR ON MY 2003 TOYOTA SIENNA FREQUENTLY CLOSES WITHOUT WARNING AND SEVERAL TIMES IT HAS CLOSED ON MY DAUGHTER. IT IS SUPPOSE TO HAVE A SENSOR THAT WOULD PREVENT IT FROM COMPLETELY CLOSING IF SOMETHING OR SOMEONE IS IN THE WAY BUT IT DOESN'T WORK. I'VE HAD TO PULL MY DAUGHER WAY FROM THE DOOR AS IT WAS PRESSING AGAINST HER. THIS IS A REAL SAFETY CONCERN. THE VAN HAS ALSO RECENTLY BEGUN TO "AUTOMATICALLY" LOCK WITHOUT WARNING.

ENGINE OVERHEATED ON NUMEROUS OCCASIONS, SLOW LOSS OF RADIATOR COOLANT NOTED, AND 2 ENGINE THERMOSTATS REPLACED BEFORE CRACKED RADIATOR WAS DISCOVERED. WHILE OWNER WAS INVESTIGATING PROBLEM, IT WAS DISCOVERED THAT TOYOTA ISSUED A COUPLE OF YEARS AGO A TSB AND A LIMITED WARRANTY EXTENSION TO REPLACE RADIATORS FROM THIS YEAR (2004) AND THE NEXT (2005) OF THE SIENNA VAN. HOWEVER, WE HAVE BEEN ONLY OWNER OF THIS VAN AND HAVE RECEIVED EVERY OTHER NOTICE FROM TOYOTA REGARDING THIS MODEL YEAR OF VAN INCLUDING THE BAD DOOR HINGES (REPLACED UNDER WARRANTY), GAS STRUTS ON REAR HATCH (REPLACED UNDER WARRANTY), AND BAD SEAT BELT BEZEL (REPLACED UNDER WARRANTY) - BUT WE NEVER RECEIVED ANY NOTICE OF THE RADIATOR ISSUE - OUR RADIATOR IS NOW DAMAGED BEYOND REPAIR AND NEEDS REPLACEMENT AND TOYOTA WILL NOT REPLACE EVEN THOUGH THIS IS APPARENTLY A WELL KNOWN ISSUE AT TOYOTA. THERE SHOULD BE A FULL RECALL ON THIS ITEM GIVEN THE AMOUNT OF KNOWN BAD RADIATORS OUT THERE. THIS IS A SAFETY ISSUE AS THE RADIATOR IS PRONE TO SUDDEN AND CATASTROPHIC FAILURE. THE ONLY KNOWN REPAIR IS TO REPLACE THE RADIATOR. THERE IS EXTENSIVE ONLINE DOCUMENTATION OF THIS ISSUE - BUT TOYOTA CONTINUES TO STONEWALL MOST OWNERS ON THIS PROBLEM DUE TO THE EXPENSE (THIS IS MUCH MORE EXPENSIVE TO FIX THAN THE BAD HINGE, GAS STRUT, AND SEAT BELT BEZEL THAT DID HAVE SAFETY BULLETINS ISSUED ON THEM.

MY AIR CONDITIONING FAILED ON MY SIENNA TOYOTA VAN. I HAD MY MECHANIC UNPLUG IT. I DID NOT HAVE ANY DAMAGE BUT CAN NO LONGER USE AC. ON LINE, I FOUND MANY OTHER SIENNA 2004 OWNERS WITH SIMILAR COMPLAINTS. SOME HAD CARS STOPPING. TOYOTA NEVER ISSUED A RECALL BUT DID A BULLETIN. THE COST IS TREMENDOUS TO FIX. *TR

ENGINE CODE P2241 COME ON SEVERAL TIMES. TOYOTA SHOULD COVER THIS UNDER EMISSION WARRANTY. IT HAPPEN 3 TIMES, IN 07/10/2007, THEN IN 2008 AND NOW AGAIN. *TR

THE AIR CONDITIONING IN OUR 2004 TOYOTA SIENNA LE STOPPED BLOWING COLD AIR AT 75,000 MILES. IT SOMETIMES REMAINS COLD FOR A MINUTE OR SO AND THEN GOES RIGHT BACK TO JUST WARM AIR. IT OCCURS EVERY TIME THE CAR IS STARTED. *TR

CHECK ENGINE LIGHT CAME ON IN 2004 SIENNA LE, CALLED DEALERSHIP FOR APPT, THE NEXT DAY, THE AIR CONDITIONING WENT OUT. I LIVE IN PHOENIX, AZ, WHERE IT IS ROUTINELY 115 IN THE SUMMER. TOOK CAR VAN TO DEALERSHIP WHERE PRICE TO FIX IS $4200. COMPRESSOR EXPLODED AND SENT SHARDS OF METAL THROUGHOUT ENTIRE A/C SYSTEM. TOYOTA IS AWARE OF THIS PROBLEM, AS POSTED IN THEIR TSB AC003-05, BUT REFUSES TO COVER THEIR DEFECT UNDER A RECALL AS IT'S NOT LIFE-THREATENING. LET ME TELL YOU, RIDING IN A CAR FOR ANY LENGTH OF TIME IN 115 DEGREE WEATHER IS LIFE-THREATENING. A/C IS NOT A LUXURY IN AZ; IT IS NECESSARY FOR SURVIVAL. UPON CONTACTING TOYOTA CUSTOMER SERVICE, THEY DENY ANY CULPABILITY; HOWEVER, THERE ARE PLENTY OF FORUMS, INCLUDING TOYOTANATION.COM, IN WHICH PEOPLE HAVE ROUTINELY HAD THIS PROBLEM WITH THIS VEHICLE. WOULD LIKE TOYOTA TO ISSUE A RECALL FOR THEIR DEFECT AND TAKE CARE OF THEIR CUSTOMERS. THEY ARE AWARE OF THE PROBLEM AND TO DEEM IT NON-LIFE-THREATENING IS A MISTAKE. MOST PEOPLE WHO OWN MINI-VANS ARE TRANSPORTING CHILDREN AND IT DOESN'T TAKE MUCH FOR CHILDREN TO OVERHEAT IN A NON-AIR CONDITIONED CAR, NOT TO MENTION THE MILD HEAT EXHAUSTION THAT COMES FROM BEING IN THE CAR FOR 15 MINUTES. CAR IS STILL NOT FIXED DUE TO EXORBITANT COST AND IT IS WELL OVER 100 HERE STILL IN SEPTEMBER. *TR

WHILE ATTEMPTING TO ACCELERATE BY PRESSING THE GAS PEDAL TO APPROXIMATELY 3/4 OF IT'S TRAVEL, I EXPERIENCED NO THROTTLE RESPONSE FOR 1-2 SECONDS WITH CARS COMING TOWARDS ME. THE ENGINE THEN PROCEEDED TO REV TO THE PROPER LEVEL I WAS EXPECTING. THIS TYPE OF SITUATION ALSO HAPPENS WHILE ATTEMPTING TO PASS A CAR ON THE FREEWAY BY PRESSING THE GAS PEDAL QUICKLY. THE CAR ONCE AGAIN HESITATES AND THEN RESPONDS IN 1 -2 SECONDS. THE VEHICLE IS A TOYOTA SIENNA 2004 XLE FWD. I'VE TRIED TO USE DIFFERENT FUEL GRADES, AC ON/OFF, TIRES PROPERLY INFLATED, NO ONE IN CAR/CAR FULL, DAY AND NIGHT, ALL WITH THE SAME RESULT. *TR

I BOUGHT A 2004 TOYOTA SIENNA CE IN OTTAWA, ONTARIO, CANADA, FROM A DEALER, NEW, OFF THE LOT IN AUGUST 2004. BY THE FIRST WINTER, BOTH BACK SLIDING DOORS WOULD FREEZE SHUT, ESPECIALLY THE PASSENGER SIDE, AND WOULD NOT OPEN UNTIL THE VEHICLE GOT REALLY HOT INSIDE. THE DEALER HAD NO SOLUTION, OFFERED NO SOLUTION. IN ADDITION, BY THE SECOND YEAR WE HAD THREE RADIATORS INSTALLED, AND HAD BOTH FRONT DOORS REPAIRED FOR RUSTING UNDER A GENERAL RECALL. ALSO, THE REAR FAN HAS BEEN GOING ON AND OFF, EVEN WITH THE SWITCH IN THE "OFF" POSITION. WE HAVE TAKEN THIS ISSUE TO THE DEALER MANY TIMES, BUT THEY DO NOT HAVE AN ANSWER, NOR A STRATEGY TO FIGURE OUT WHY IT DOES THIS. FINALLY, THIS VEHICLE HAS RATTLED INSIDE FROM DAY ONE AND IS UNPLEASANT TO DRIVE. I FIND THE TOYOTA DEALERS NOT INTERESTED IN YOU ONCE YOU BUY THE CAR, BUT AFTER THREE YEARS TO THE DAY THE CALLED ME WANTING TO KNOW IF I'D BUY A NEW ONE. I WILL NOT BUY ANOTHER TOYOTA. *TR

TL*THE CONTACT OWNS A 2004 TOYOTA SIENNA. WHILE DRIVING UNDER 40 MPH, THE AIR CONDITIONER FAILED TO WORK PROPERLY. THE AIR CONDITIONER STOPPED WORKING AND THE TEMPERATURE ON THE THERMOSTAT CONTINUED TO RISE THE FOLLOWING DAY. THE CONTACT CHECKED THE COOLANT AND NOTICED THAT THERE WAS NO ANTIFREEZE; THEREFORE, SHE REFILLED THE RADIATOR. THIS DID NOT KEEP THE VEHICLE FROM OVERHEATING. SHE TOOK THE VEHICLE TO A LOCAL DEALER AND THEY STATED THAT THERE WAS A LEAK IN THE RADIATOR CORE. THE VEHICLE HAS NOT BEEN REPAIRED. THE VIN WAS UNKNOWN. THE FAILURE AND CURRENT MILEAGES WERE 93,000.

TL*THE CONTACT OWNS A 2004 TOYOTA SIENNA. WHEN TURNING A CORNER AT APPROXIMATELY 5-10 MPH THE VEHICLE WOULD HESITATE AND LOSE POWER. THE DEALER STATED THAT THE VEHICLE NEEDED A COMPUTER UPDATE, HOWEVER; THE SYSTEM WAS UNAVAILABLE. THE DEALER STATED THAT THE FAILURE WAS NOT NORMAL. THE CURRENT MILEAGE WAS 100,000. THE FAILURE MILEAGE WAS UNAVAILABLE.

DRIVING ABOUT 15 MPH THROUGH PARKING LOT...AN ALARM SOUNDED FOLLOWED BY A "LOUD NOISE" FROM THE REAR. THIS WAS FOLLOWED BY THE CAR BRAKING AND PULLING TO THE RIGHT. ENGINE DID NOT STOP. THE CAR WOULD ONLY CRAWL WHEN ATTEMPTS WERE MADE TO DRIVE IT. ANY FASTER THAN 2-5 MPH CAUSED REPEAT OF THE EVENT. NO INFORMATION LIGHTS WERE ACTIVATED ON THE DASHBOARD. CAR WAS TAKEN BY FLATBED TO TOYOTA DEALERSHIP. ACCESS TO THE ONBOARD COMPUTER BY THE SERVICE PEOPLE AT DEALER DID NOT REVEAL ANY FAULTS. AN ATTEMPTED SOLUTION WAS TO REPROGRAM THE ABS MODULE. THIS DID NOT RESOLVE THE PROBLEM. AT THIS TIME, THE CAR REMAINS AT THE DEALERSHIP. REPORT FILED WITH TOYOTA REGIONAL BY BOTH DEALER AND MYSELF. *TR

ENGINE FAILURE DUE TO OIL GUMMING. *NM

THE AUTOMATIC SLIDING DOOR ON MY 2004 SIENNA HAS BEEN A PROBLEM SINCE WE PURCHASED THE VEHICLE. AT TIMES, WE CAN'T OPEN THE DOOR FROM THE OUTSIDE AND OTHER TIMES, WE CAN. ALSO, WE RECENTLY CLOSED THE DOOR WITH THE AUTOMATIC BUTTON AND FOR NO APPARENT REASON, THE CABLE BROKE SO THAT WE NOW HAVE TO OPEN AND CLOSE THE DOOR MANUALLY. ALSO, WE HAVE HAD ISSUES WITH THE ACCELERATION OF THE VEHICLE IF WE ARE GOING FROM A STOP POSITION OR A SLOW MOVING (LESS THAN 10 KM/H) POSITION. THE VAN SEEMS TO SLOW DOWN BEFORE SHIFTING INTO GEAR. THIS IS A SERIOUS PROBLEM WHEN DRIVING ESPECIALLY WITH CHILDREN IN THE VEHICLE. MY WARRANTY HAS EXPIRED AND I'M LOOKING AT HAVING TO PAY FOR THIS ON MY OWN. I AM DISSATISFIED WITH TOYOTA, I HAVE HAD THIS VEHICLE FOR ONLY 2 YEARS AND I HAVE HAD THREE RECALLS ALREADY. THIS IS MY 2ND TOYOTA PRODUCT AND MY LAST. *NM

DT*: THE CONTACT STATED WHILE DRIVING OUT OF A DRIVEWAY AT 5 MPH, THE VEHICLE STALLED WHEN ACCELERATION WAS ATTEMPTED. THE ENGINE WARNING SIGNAL ILLUMINATED. THE PROBLEM HAD REOCCURED FREQUENTLY AT ANY SPEED. THE DEALERSHIP WAS NOT ABLE TO DUPLICATE THE DEFECT IN NINE TIMES THE VEHICLE HAD BEEN TAKEN TO CORRECT THE PROBLEM. THE CONTACT DECIDED TO OBTAIN A SECOND OPINION FROM AN INDEPENDENT CERTIFIED MECHANIC WHO OBSERVED THE COIL IGNITION ASSISTANCE BURNED OUT AND THE FIFTH CYLINDER WAS MISFIRING. THE SECOND OPINION WAS RATIFIED BY ANOTHER DEALERSHIP. THE CONTACT EXPRESSED THE DEALERSHIP DELAYED THE REQUIRED REPAIRS UNTIL THE VEHICLE REMAINING WARRANTY WERE EXHAUSTED. THE DEALERSHIP WAS NOW READY TO MAKE THE REPAIRS.

DT*: THE CONTACT STATED A LOUD RATTLING NOISE WAS HEARD COMING FROM THE ENGINE COMPARTMENT OF THE VEHICLE EVERY TIME IT WAS STARTED. THERE WERE NO INDICATIONS OF ANY ADDITIONAL PROBLEMS. THE VEHICLE WAS TAKEN TO A SALES DEALER THREE TIMES, AND THE DEALER WAS UNABLE TO DUPLICATE THE PROBLEM. UPDATE ONH 06/05/2006. *AK

TOYOTA SIENNA 2004, 19,000 MILES NOT EVEN 2 YEARS OLD. 1. VALVES MAKING NOISE WHEN DRIVING UP HILL AT SLOW SPEED OR WHEN START DRIVING. 2. WIND NOISE IS UNACCEPTABLE. PROBLEM BEGINS AT THE VERY FIRST DAY OF DRIVING THE CAR. 3. ONE BIG KNOCKING NOISE WHEN THE VEHICLE IS MOVING , ONLY WHEN SHIFT FROM PARK TO D4 AND STARTING TO DRIVE. *AK

2004 TOYOTA SIENNA LE--STRONG SULFUR LIKE ODOR EMITTING FROM EXHAUST ESPECIALLY NOTED DURING COLD WEATHER. TOOK VEHICLE IN FOR EVALUATION AND TOLD NO PROBLEM--MOST LIKELY "QUALITY OF GASOLINE". A MECHANIC FRIEND SUGGESTED "CATALYTIC CONVERTER" PROBLEM. CONCERNED ABOUT LONG TERM CONSEQUENCES!

RADIATOR RUPTURED AND THE ENGINE OVERHEATED; HOSE REPLACED IN STEERING COLUMN RECALL; RUST PROTECTIVE TAPE RECALL; DVD SCREEN REPLACED AND THE ENTIRE DVD PLAYER REPLACED(SCREEN STILL NOT EASILY VISIBLE IN MIDDLE ROW); PASSENGER SEAT BELT REPLACED; MIDDLE PASSENGER SEAT BELT FAILING; GASOLINE SMELL INSIDE OF CAR WITH AC ON RECIRCULATION; DRIVER'S WINDOW FELL INSIDE DOOR IN SNOW STORM AND WAS NOT CONSIDERED A SAFETY ISSUE TO GET A LOANER VEHICLE EVEN THOUGH THE VEHICLE COULD NOT BE LOCKED; TIRES COMPLETELY BALD AND LEAKING UNDER 30,000 MILES, DVD PLAYER MUST BE AT A HIGH DB VOLUME AND WHEN RETURNED TO RADIO/CD WILL ALMOST DEAFEN YOU; INTERIOR LIGHTS HAVE TO BE MANUALLY OVER RIDDEN OR WILL DRAIN BATTERY; CAR HESITATES 1-2 SECONDS WHEN TRYING TO QUICKLY ACCELERATE AND THEN LURCHES FORWARD ALARMINGLY; CRUISE CONTROL IS NOT FUNCTIONING; WAITING TO HAVE FUEL MIXTURE SENSOR REPLACED. I WAS NOT INFORMED OF FIRST 2 RECALLS UNTIL I MY ENGINE OVERHEATED. I DID GET THE RUST RECALL AND A STICKER ON MY SLIDING DOOR INFORMING USER OF DANGER OF HAVING MIDDLE WINDOWS OPEN WHILE OPENING THE MIDDLE DOOR COULD CATCH A HEAD OR OTHER EXTREMITY. TOYOTA DEALER SERVICE MANAGER SAYS MINE IS THE ONLY 04 SIENNA EXPERIENCING ANY PROBLEMS EXCEPT FOR THE RECALLS ON THE RADIATOR; THE STEERING HOSE; THE RUST TAPE; AND THE MIDDLE SEAT BELT. NOT SO ACCORDING TO ALL I HAVE READ HERE. MOST OF THE PROBLEMS HAVE OCCURRED BETWEEN 22,000 AND 34,000 MILES; THE DVD SCREEN ALWAYS FAILED TO LOCK INTO A GOOD POSITION FOR THE MIDDLE ROW VIEWERS. *NM

2004 TOYOTA SIENNA LE. VEHICLE HESITATES WHEN ACCELERATION. THERE IS A BIG DELAY BEFORE THE CAR GAINS SPEED. THIS IS A ON GOING PROBLEM. DEALER STATES THAT THE CAR WAS MADE THAT WAY AND THERE IS NOTHING THAT THEY CAN DO TO CORRECT THE PROBLEM. THIS HESITATION CAN CAUSE AN ACCIDENT AT ANY TIME.

MINIVAN DOES NOT ALWAY ACCELERATE PROPERLY. WHEN THE VEHICLE IS SLOWING DOWN, LIKE WHEN COMING TO A RED LIGHT, THE VEHICLE WILL HESITATE WHEN I TRY TO ACCELERATE IF I HAVE NOT ALREADY COME TO A COMPLETE STOP. THIS SEEQUENCE WILL USUALLY REPRODUCE THE FAILURE: 1. TRAVEL AROUND 40MPH. 2. QUICKLY SLOW TO AROUND 10MPH. 3. TRY TO QUICKLY ACCELERATE TO 40MPH AGAIN. THE VEHICLE WILL HESITATE AND PAUSE BEFORE STARTING TO ACCELERATE.

01/11/05: VEHICLE STALLED WHILE IN MOTION. TOWED TO LOCAL FACILITY. LATER VEHICLE SUCCESSFULLY STARTED AND INDICATED NO PROBLEMS UPON TEST DRIVE. 01/30/05: DRIVING KIDS TO SNOWBOARDING WHEN VEHICLE STALLED IN MOTION. RESTARTED. DROVE ON SIDE OF ROAD - STALLED AGAIN - RESTATED. CHECK ENGINE LIGHT (ALONG WITH SEVERAL OTHERS) NOW ACTIVATED. DROVE ON SIDE OF ROAD AS VEHICLE WOULD NOT ACCELERATE ABOVE 10MPH AND WOULD STALL REPEATEDLY. 01/31/05: I CONTACTED SERVICE DEPARTMENT AT HANDY DODGE TOYOTA (HDT), TO REPORT BREAKDOWN AND ARRANGED FOR SERVICE. 02/04/05: HDT PERFORMED AIR-INTAKE VALVE REPLACEMENT AND SEVERAL OTHER SERVICE CAMPAIGNS. 02/24/05: VEHICLE STALLED WHILE IN MOTION. VEHICLE RESTARTED, BUT WOULD NOT ACCELERATE OVER 10MPH. VEHICLE CONTINUED TO STALL WHILE IN MOTION AND CHECK ENGINE LIGHT ACTIVATED. STALLED WHILE ON A BLIND HILL/CORNER ON ROUTE 104. I COULD NOT PULL OFF TO SIDE OF ROAD AS THERE WAS NO SHOULDER AND GUARD-RAILS HUGGED IMMEDIATE SIDE OF ROAD. I WAS IN THE ROAD FOR ABOUT 10 MINUTES WITH MY EMERGENCY LIGHTS FLASHING WHILE CONTINUOUSLY ATTEMPTING TO RESTART VEHICLE. VEHICLE RESTARTED AND I WAS ABLE TO DRIVE TO A PARKING AREA FOR A TOW. HDT CONTACTED ME TO INFORM THAT FAILURE WAS SAME AS BEFORE AND THROUGH FURTHER RESEARCH AT THE NATIONAL LEVEL THAT THEY LEARNED THAT STALLING IS OCCURRING IN TOYOTA SIENNA AND 4RUNNERS IN THE COLD WEATHER STATES DUE TO A DEFECT IN THE GAS TANK DESIGN AND THAT THERE IS CURRENTLY NO REPAIR AVAILABLE. RECOMMEND RUNNING VEHICLE WITH NO LESS THAN HALF A TANK OF GAS (AT ALL TIMES) AND WERE VERBALLY OPTIMISTIC THAT THE COLD WEATHER WOULD BE ENDING IN THE NEXT WEEK OR TWO. I INFORMED HDT THAT I DRIVE AN HOUR (EACH WAY) TO AND FROM WORK EVERY DAY (HIGHWAY AND BACK ROADS) AND TO BE EXPECTED TO DO THAT EACH DAY IN A DEFECTIVE VEHICLE (THAT HAS A HISTORY OF STALLING) IS UNSAFE AND UNACCEPTABLE. I HAVE SINCE FILED LEMON LAW DEMAND FOR ARBITRATION WHICH CASE IS IN PROGRESS.

OVERHEATING RADIATOR, I WAS TOLD IT WAS A PRODUCT RECALL FROM TOYOTA,I WAS NEVER NOTIFIED, NOR DO I SEE THE RECALL MENTIONED ANYWHERE,I WAS ALSO TREATED VERY RUDELY AT BOCH TOYOTA IN NORWOOD MA WHEN I COMPLAINED ABOUT IT. *NM

VEHICLE WAS TOWED TO THE DEALER, WHO D REPLACED THE RADIATOR, WHICH WAS COVERED UNDER A RECALL. CONSUMER STATED HE WAS NEVER NOTIFIED OF THIS RECALL.*AK

I BOUGHT THE TOYOTA SIENNA ON JULY 4 2003. I RECEIVED A RECALL NOTICE WITHIN A MONTH AND HAD REPAIR DONE ON AUGUST 29, 2003. THE GASOLINE TANK REPAIR WAS DONE INCORRECTLY, RESULTING IN ME BEING STRANDED AWAY FROM MY HOME, WITH TWO KIDS IN THE CAR, WITH GASOLINE OOZING ALL OVER THE GROUND. THIS WAS A CLEAR FIRE HAZARD. THEN IN OCTOBER 2004, I WAS DRIVING ON THE HIGHWAY, THE DRIVER SIDE WINDOW CAME OUT OF THE FRAME. THE DEALERSHIP AGREED IT WAS MANUFACTURER'S DEFECT AND FIXED IT. I FELT VERY UNSAFE DRIVING HOME IN THAT CAR. E NOW HAVE RECEIVED A RECALL NOTICE ABOUT STEERING FLUID HOSE DEFECT AND RADIATOR DEFECT. WITH 5 DEFECTS IN ONE YEAR AFTER BUYING A NEW CAR I FEEL IT IS A SAFETY HAZARD TO DRIVE THIS VEHICLE WITH TWO KIDS. THIS IS ALSO THE CAR I USE FOR COMMUTING. I CANNOT RELY ON THIS VEHICLE ANY MORE.*AK

DRIVING 55 MPH THE ENGINE WARNING LIGHT ILLUMINATED. SMOKE CAME FROM THE REAR OF THE VEHICLE. THE CONSUMER MANAGED TO PULL OVER AND HAD THE VEHICLE TOWED. THE DEALERSHIP WAS NOTIFIED, BUT DID NOT RESOLVE THE PROBLEM. THE CAUSE WAS NOT DETERMINED. PLEASE PROVIDE MORE INFORMATION. *NM

SAID TOYOTA IS AWARE OF THE PROBLEM. I WOULD LIKE TO KNOW WHAT THE PROBLEM IS AND WHEN IT WILL BE FIXED.
