2008 TOYOTA SIENNA Engine Problems

The head gasket that was repaired failed and the radiator system also failed. Im not sure if these issues are dealer related or manufacture related as i spoke to the previous owner and they stated they had the vehicle serviced at a manufacturer prior to doing a trade in with the dealer

The contact owns a 2008 Toyota Sienna. The contact stated while pulling into a grocery store, he heard an abnormal ticking sound. The contact stated upon parking and inspecting the outside of the vehicle, he noticed that engine oil was leaking onto the ground. Additionally, the oil dipstick was dry upon inspecting the oil level. There was no warning light illuminated. The vehicle was taken to a local Pep Boys where oil was added in the vehicle and the contact drove to his residence. However, the failure persisted while driving. The vehicle was towed to the dealer where it was diagnosed that the exhaust cam gear had fractured, causing damage to the engine and other unnamed components. The dealer diagnosed that the engine, the exhaust cam gear, and the timing chain needed to be replaced, and additional unknown repairs were also needed. The vehicle was not repaired. The contact related...

CAR SPEED VARIES WHEN DOING A MODERATE SPEED EXAMPLE 40 MPH SOMETIMES FEELS LIKE ITS ENGINE SLIPS AND SPEED SLOWS CAR JUMPS FORWARD FEELS LIKE ENGINE SLIPS OR GEAR SHIFTS. ENGINE BOGS DOWN OR SOMETIMES REVS UP A LITTLE..SCARES ME SOMETIMES BUT NO CHOICE BUT TO DRIVE

CHECK ENGINE LIGHT, VSC LIGHT AND TRAC OFF LIGHT ON AND OFF LIGHT INTERMITTENT. AT ANY TIME THE LIGHT GOES ON AND OFF. IT IS NERVE BREAKING KNOWING THAT THE WARNING LIGHT AND THE PROBLEM CAN NOT BE FIXED BY TOYOTA. I HAVE MY TOYOTA SIENNA 2008 AND IT HAVE A VERY LOW MILES DUE TO LIGHTS SAFETY REASONS THAT CAN NOT BE SOLVED BY TOYOTA. EVERY TIME WE COMPLAIN, WE WERE ALWAYS TOLD THAT BRING THE CAR IN WHEN THE LIGHT GOES ON. THE PROBLEM IS WHEN THE LIGHT GOES ON IT WILL BE OFF WHEN WE GET TO THE DEALERSHIP. WE NOTICED WHEN THE CAR REACHED APPROXIMATELY 98,000 MILES. THE CAUSE OF THE ON AND OFF LIGHTS ARE UNKNOWN.

WHILE DRIVING WITH MY AUTISTIC CHILDREN THE CHECK ENGINE LIGHT, THE VSC LIGHT AND THE TRAC OFF LIGHT ALL CAME ON AND THE WHEELS LOCKED UP ON THE RIGHT SIDE AND THROUGH THE VAN INTO A DITCH. THIS IS VERY DANGEROUS SINCE THIS VEHICLE WAS MADE FOR FAMILIES. I AM NOW KEEPING A LOG AND I DO PLAN ON RETAINING AN ATTORNEY AS NO ONE HAS ADDRESSED THIS ISSUE AS A SAFETY HAZARD. *TR

LOWER OIL COOLER LINE DEVELOPED HOLE AND LEAKED ENGINE OIL WHILE IN MOTION ON COUNTY HIGHWAY.

TL* THE CONTACT OWNS A 2008 TOYOTA SIENNA. WHILE OPERATING THE VEHICLE, THE ENGINE HESITATED AND SHUDDERED BEFORE STALLING. THE VEHICLE WAS TAKEN TO TOYOTA OF ORLANDO (3575 VINELAND RD, ORLANDO, FL) WHERE IT WAS DIAGNOSED THAT THE ENGINE CAMSHAFT WAS FAULTY AND THE ENGINE WOULD NEED TO BE REBUILT. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED, BUT NO ASSISTANCE WAS OFFERED. THE CONTACT INDICATED THAT THE VEHICLE PREVIOUSLY EXPERIENCED THE SAME FAILURE IN 2011 AND THE ENGINE WAS REBUILT. FURTHERMORE, IN 2016, THE CAMSHAFT WAS REPAIRED. THE VIN WAS NOT AVAILABLE. THE FAILURE MILEAGE WAS 170,000.

VVTI OIL LINE HAS LARGE HOLE ALL OF A SUDDEN, CAUSED VERY QUICK LOSS OF ALL OIL IN CAR. I WAS IN MOTION ON THE HIGHWAY, AND OIL LIGHT CAME ON. I WAS ABLE TO GET THE CAR PULLED OVER AND STOPPED. IF I HAD BEEN IN A WORSE POSITION, IT WOULD HAVE CAUSED ENGINE SEIZURE. THERE IS A LIMITED SERVICE CAMPAIGN ON THIS, MY VEHICLE HAD IT REPLACED IN 2014, AND IT FAILED AGAIN BECAUSE THEY PUT THE SAME FAULTY PART WITH RUBBER HOSE CONNECTOR. IN 2010 THEY ACTUALLY RELEASED SAME ENGINE WITH AN ALL METAL OIL HOSE, BUT THATS NOT WHAT THEY REPLACED IT WITH ON THE TECHNICAL SERVICE CAMPAIGN.

THIS VEHICLE HAS 3 OPEN RECALLS ON IT I HAVE CONTACTED MY LOCAL TOYOTA DEALERSHIP IN WOOSTER OHIO AND THE SERVICE ADVISOR INFORMED ME IT WOULD TAKE A FEW HOURS TO DO ALL THE REPAIRS AND ID HAVE TO WAIT OR DROP IT OFF I AS A CUSTOMER FEEL ITS UNFAIR FOR TOYOTA TO MAKE A CUSTOMER WAIT FOR HOURS TO FIX REPAIRS THAT ARE FAULTS OF THE CAR MANUFACTUER I ASKED FOR A LOANER CAR WHILE THE WORK IS COMPLETED THEY REFUSED SAYING THE ONLY WAY A LOANER IS GIVEN IS IS THE RECALL IS DOOR RELATED

MY 2008 TOYOTA SIENNA BEGAN TO CREATE A SMOKE SCREEN IMPAIRING ME FROM HAVING A CLEAR VISUAL OF THE ROAD. I HAD TO IMMEDIATELY PULL TO THE SIDE OF THE FREEWAY AND CHECK IF MY VEHICLE WAS ON FIRE. ONCE I INSPECTED THE OUTSIDE AND OPEN THE HOOD TO MAKE SURE NOTHING WAS ON FIRE I NOTICE A PUDDLE OF OIL UNDER THE VEHICLE AN UPON FURTHER LOOK MY ENGINE MOTOR OIL COOLING HOSE HAD BURST, SPRAYING THE MOTOR AND EVERYTHING INSIDE WITH MOTOR OIL. THIS WAS THE 3RD TIME THIS VEHICLE HAS DONE THE SAME PROBLEM.

WHILE PUTTING ON THE BRAKES TO STOP FOR A TRAFFIC LIGHT THE ENGINE SUDDENLY REVVED UP TO 6000 RPM AND TRIED TO TAKE OFF BY ITSELF. I PUSHED THE GEAR SHIFT INTO NEUTRAL AND PUT MY LEFT FOOT ON THE BRAKE TO KEEP THE CAR FROM MOVING. I KICKED THE ACCELERATOR PEDAL SEVERAL TIMES UNTIL IT DISENGAGED. THIS IS THE 4TH TIME THIS HAS HAPPENED. THERE WAS NOT A FLOOR MAT INVOLVED AS THERE WAS NOT ONE IN THE CAR AT THIS TIME. THE LAST TIME I TALKED TO A TOYOTA DEALER ABOUT THIS THEY SAID THIS COULD NOT HAPPEN AND I WAS WRONG ABOUT WHAT HAPPENED. THE DEALER DID NOT DOCUMENT ANY OF THIS AND WANTED NOTHING FURTHER TO DO WITH ME. THIS IS DANGEROUS AND HAPPENS WITH NO WARNING WHEN YOU PUSH THE BRAKE PEDAL TO STOP FOR A TRAFFIC SIGNAL OR TO PULL INTO A PARKING SPACE....

THAT WAS AROUND 2012 NEW YEAR TIME WHEN I , MY WIFE AND MY KID VISITED OUR FRIEND AT ATLANTA, GA. WE DROVE OUR VAN ON INTERSTATE HIGHWAY I-75, IN THE MIDDLE OF OUR TRIP, OUR VAN STARTED SHAKING VIGOROUSLY. I FELT THAT WAS FROM ENGINE, IT FORCED ME TO STOP ON THE SIDE OF I-75. AFTER A WHILE WE RESTARTED OUR VAN, WE COULD ONLY DRIVE FOR < 65 MILES/HOUR. ANY ACCELERATION RESULTED IN VIGOROUS SHAKING. AFTER WE CAME HOME I DROVE MY VAN TO AN AUTO SERVICE CENTER, AND WAS CHECKED. IT TURNED OUT THAT 3 IGNITION COILS, SPARK PLUGS, AND MANIFOLD GASKET HAD TO BE REPLACED. YESTERDAY (9/10/2015) THE SAME PROBLEM HAPPENED AGAIN.

CAR COMPLETELY STOPED WITHOUT ANY WARNING ON AN EXTREMLY BUSY ROAD. EXTREMELY LOUD NOISES ARE COMING FROM THE ENGINE AND CAR WILL NO LONGER MOVE. STILL CLUESSLESS ON THE ISSUE AT HAND.

UPON EXITING THE INTERSTATE, WE BEGAN TO SMELL A BURNING SMELL AND THE LIGHT FOR THE A/C STARTED FLASHING AND WOULDN'T TURN BACK ON. WE DROVE ABOUT A MILE THINKING THAT THE SMELL WAS ROADWORK, BUT THEN WE DECIDED TO STOP AND CHECK IT UNDER THE HOOD. ONCE WE OPENED THE HOOD, WE WERE HIT WITH A PLUME OF SMOKE, AND REALIZED THERE WAS A POOL OF OIL UNDER THE VAN. WE BEGAN TO LOOK ON THE INTERNET FOR CAUSES, WHERE WE CAME ACROSS SEVERAL INSTANCES OF THE OIL HOSE BLOWING AND THE VEHICLE CATCHING FIRE. WE CALLED THE DEALERSHIP THE NEXT DAY TO SEE IF THERE WAS A RECALL. THEY DIDN'T KNOW OF ONE, BUT STATED THAT THEY'D FIXED SEVERAL VEHICLES FOR THE SAME ISSUE. THIS IS VERY ALARMING SINCE THE CHECK ENGINE LIGHT, OIL LIGHT, ETC DIDN'T EVEN TURN ON. HAD WE DRIVEN ANOTHER MILE, WOULD THE VAN...

VARIABLE VALVE TIMING OIL SUPPLY LINE SPRANG A LEAK AT BEND ON RUBBER TUBING. TOYOTA HAS A NEW REPLACEMENT TUBE ,BUT NOT PAYING FOR TUBE OR LABOR. *TR

MY WIFE WAS DRIVING THE MINIVAN WITH BOTH KIDS IN THE CAR AFTER GROCERY SHOPPING AND PICKING THEM UP FROM THE PRESCHOOL. WHILE SHE WAS DRIVING INTO THE GARAGE SHE SMELLED AND SAW OIL FUME COMING OUT OF THE HOOD. SHE THOUGHT THE CAR WAS GOING TO CATCH FIRE AND GRABBED THE KIDS AND GOT OUT OF THE VAN AS QUICKLY AS SHE CAN. I GOT HER CALL AND RUSHED HOME FROM WORK. IT TURNED OUT THERE WAS A SUDDEN FAILURE OF A OIL COOLING PIPE ON THE ENGINE. ALL OF THE ENGINE OIL HAD ALMOST LEAKED OUT (THERE WAS MAYBE ABOUT QUARTER OF INCH SHOWING ON THE DIP STICK). AFTER WE TOWED THE CAR TO THE DEALER, WE FOUND OUT THE OIL HAD LEAKED FROM AN ENGINE COOLER PIPE WHICH WAS POORLY DESIGNED AND OVER TIME IT COULD DEVELOP A SLOW SEEP LEAK OR IN OUR CASE FAILED IN...

THE VEHICLE CAME TO A STOP AT A STOP LIGHT AND THE ODOUR OF SOMETHING BURNING ENTERED THE CABIN. NO LIGHTS ON THE DASH APPEARED AND DROVE TO THE NEXT PARKING LOT TO FIND A TRAIL OF OIL BEHIND THE VEHICLE AND A POOL OF OIL UNDER THE ENGINE. I HAD THE VEHICLE TOWED DIRECTLY TO THE DEALER TO FIND OUT A 'PIN HOLE' WAS FOUND IN THE OIL COOLER HOSE. THIS IS NOT THE SAME HOSE AS THE VVTI THAT HAS BEEN RECALLED ALREADY. THE DEALER INFORMED ME IT'S LIKE THE TWO OTHER RUBBER HOSES CARRYING OIL ON THE ENGINE BUT HAS NOT BEEN RECALLED. THE COST TO HAVE IT REPLACED WITH A STEEL LINE IS $429 CDN. THIS VAN WAS PURCHASED NEW IN 2009 AND BROUGHT INTO MANITOBA, CANADA FROM THE US. *TR

TOYOTA KNOWN DEFECTIVE TIMING CHAIN GASKET. LEAKING OIL. *TR

UPON EXITING FREEWAY IN BUTTE, MT, AND SLOWING DONE FOR RED LIGHT AT BOTTOM OF RAMP, HEARD TAPPING NOISE COMING FROM ENGINE. DROVE ONE BLOCK TO GAS STATION, AND WHILE PUMPING GAS, NOTICED LARGE QUANTITY OF ENGINE OIL PUDDLING UNDER THE ENGINE. HAD VEHICLE TOWED TO TOYOTA DEALER, WHO DETERMINED THAT OIL COOLER HOSE HAD RUPTURED. FORTUNATELY, NO APPARENT ENGINE DAMAGE. AFTER SOME RESEARCH ON SIENNA OWNERS' FORUM, LEARNED THAT THIS WAS A RECURRING PROBLEM ON CERTAIN TOYOTA MODELS IN CERTAIN YEARS, INCLUDING THE 2008 SIENNA WITH TOW PACKAGE LIKE OURS, AND THAT TOYOTA HAD PUT OUT A TSB ON THIS, BUT APPARENTLY HAD NEVER INFORMED OWNERS. IT TOOK 4 DAYS FOR THE REPLACEMENT HOSE TO ARRIVE, AND THE REPAIR COST $520. THIS INCIDENT OCCURRED WHILE MY FAMILY WAS FAR FROM HOME (SILVER SPRING, MD) ON A CROSS-COUNTRY TRIP AND THUS FORCED THEM TO CANCEL PART OF VACATION AND SPEND...

VVT-I HOSE BROKEN, RAPID OIL LOSS AND ALMOST NO OIL LEFT IN ENGINE WHEN PROBLEM WAS SPOTTED. OIL SPILLED TO THE BELTS AROUND THE VVT-I HOSE. WHEN TURN STEERING WHEEL, NOISE HEARD. THIS IS THE SAME ISSUE TO THE OTHER RECALLS BUT NOT APPLICABLE TO TOYOTA SIENNA. HTTP://TOYOTANEWS.PRESSROOM.TOYOTA.COM/ARTICLE_DISPLAY.CFM?ARTICLE_ID=1906 I WAS TOLD MAY CAUSE PROBLEM TURNING THE STEERING WHEEL, OR ACCIDENT. I WAS INSTRUCTED TO FILE THE CLAIM TO YOUR OFFICE. THANKS. *TR

TL* THE CONTACT OWNS A 2008 TOYOTA SIENNA. THE CONTACT STATED THAT WHILE TRAVELING 25 MPH, THE CHECK ENGINE LIGHT ILLUMINATED. THE STEERING WHEEL BECAME VERY DIFFICULT TO CONTROL AND HAD TO BE TOWED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND DIAGNOSED THAT THE ENGINE NEEDED TO BE REPLACED. THE VIN WAS NOT PROVIDED. THE FAILURE AND CURRENT MILEAGE WERE 80,000.

THE RUBBER PORTION OF THE OIL SUPPLY HOSE FOR THE WT-1 ACTUATOR FAILED RESULTING IN A SUDDEN LOSS OF SEVERAL QUARTS OF OIL. THIS OIL WAS CARRIED ALONG THE UNDERCARRIAGE AND SPRAYED A FINE MIST OF OIL ON THE WINDSHIELDS OF THE CARS BEHIND THE VAN. LUCKILY THIS OCCURRED CLOSE TO HOME AT A LOW SPEED. IF THIS WAS ON THE HIGHWAY IT COULD HAVE CAUSED SUDDEN REDUCED VISIBILITY FOR THE DRIVERS BEHIND THE VEHICLE AND COULD HAVE LED TO AN ACCIDENT. I AM SORRY BUT USING A RUBBER HOSE ON AN OIL LINE IS ONE OF THE DUMBEST THINGS I HAVE HEARD OF. FORTUNATELY FOR US, NO ONE WAS HURT AND NO DAMAGE WAS DONE TO THE VEHICLE. I DON'T UNDERSTAND HOW THIS HAS NOT TURNED INTO A RECALL. THIS WAS A BIG MISTAKE ON TOYOTA'S PART. *TR

DURING A RECENT TRIP TO ALABAMA FROM VIRGINIA, OUR 2008 TOYOTA SIENNA SUDDENLY ACCELERATED WHILE PRESSING THE BRAKE PEDAL INSTEAD OF BRAKING. BOTH TIMES, WE WERE APPROACHING MODERATELY HEAVY TRAFFIC. MY WIFE WENT TO APPLY THE BRAKES TO SLOW THE VAN. INSTEAD OF BRAKING AND SLOWING THE VEHICLE, THE VAN WENT INTO FULL ACCELERATION MODE. THE TRANSMISSION DOWNSHIFTED AND STARTED APPLYING FULL THROTTLE. THE FIRST TIME WE THOUGHT WE WERE GOING CRAZY. THE SECOND TIME, BOTH MY WIFE AND I WATCHED AS HER FOOT APPLIED THE BRAKES AND TO OUR AMAZEMENT, THE VAN STARTED ACCELERATING AGAIN! LUCKILY BOTH TIMES, MY WIFE TOOK HER FOOT OFF THE BRAKE PEDAL AND REAPPLIED ONCE THE VAN STOPPED ACCELERATING AND THE BRAKES WORKED THEN. I HAVEN'T HAD TIME TO TAKE THIS INTO THE TOYOTA DEALER YET. WE ARE STILL UNDER A 30 DAY WARRANTY WITH CARMAX, SO I HAVE COMMUNICATION OUT TO THEM TO...

MY WIFE WAS PARKING OUR 2008 TOYOTA SIENNA WITH OUR 3 YOUNG BOYS IN THE AUTOMOBILE. SHE SLOWLY BROUGHT THE VEHICLE TO A COMPLETE STOP; NEVER USING GAS, JUST COVERING AND TAPPING LIGHTLY ON THE BRAKE. ONCE THE AUTOMOBILE CAME TO A STOP MY WIFE PRESSED THE BRAKE A LITTLE MORE IN ORDER TO PUT THE VEHICLE IN PARK. AT THAT MOMENT THE VEHICLE ACCELERATED INCREDIBLE FAST, JUMPED OVER AN 8 INCH CONCRETE PARKING LOT DIVIDER AND CRASHED INTO A TREE ABOUT 10 - 15 FEET FROM THE CONCRETE DIVIDER. WE ARE CERTAIN THAT THIS WAS A "SUDDEN UNINTENDED ACCELERATION" INCIDENT CAUSED BY SOME MECHANICAL, ELECTRICAL, PROGRAMMING OR OTHER DEFECT IN THE '08 SIENNA. THIS WAS NOT "DRIVER ERROR"! MY WIFE DID NOT CONFUSE THE GAS PEDAL AND THE BRAKE. THIS WAS NOT CAUSED BY A FLOOR MAT OBSTRUCTING THE GAS PEDAL. THIS WAS CAUSED BY SOME TYPE OF A...

WHILE DRIVING MY VEHICLE IT BEGAN TO MAKE A STRANGE KNOCKING SOUND AS I ACCELERATED. I HAD BEEN DRIVING AROUND TOWN FOR SEVERAL HOURS THAT MORNING. I PULLED OVER TO INSPECT THE ENGINE, AND SAW SOME TYPE OF FLUID ON THE LEFT SIDE OF THE ENGINE AND WALL. I PULLED THE OIL DIPSTICK OUT AND THERE WAS NO OIL ON IT AT ALL. COMPLETELY DRY! I HAD SOMEONE BRING ME SOME OIL AND I DROVE MY CAR UP TO THE REPAIR SHOP JUST A SHORT DISTANCE AWAY. THEY DISCOVERED THAT THE OIL PRESSURE LINE -VALVE COVER VARIABLE TIMING-ON TOP OF MOTOR TO RIGHT ON PASSENGER SIDE HAD BURST. PART OF THE LINE IS RUBBER AND THAT PART HAD RUPTURED AND ALL THE OIL HAD BLOWN OUT OF THE ENGINE. MY OIL LIGHT DID NOT COME ON AT ANY TIME NOR DID MY CHECK ENGINE LIGHT. EVEN AFTER I STOPPED IT...

THE RUBBER IN THE OIL COOLING LINE BROKE DOWN AND DRAINED MOST OF THE OIL FROM THE ENGINE. FROM LOOKING AT THE DIFFERENT BOARDS THIS SEEMS TO BE A COMMON PROBLEM WITH THIS HOSE. TOYOTA EVEN RE-DESIGNED THE HOSE WITH A METAL SLEEVE BECAUSE OF THIS. *TR

I HAD A OIL HOSE IN MY VAN GET A HOLE. WHEN IT HAPPENED IT SPILLED OIL ALL OVER AND IN MY OPINION COULD HAVE STARTED A FIRE.THE HOSE IS CONNECTED TO A PIPE AND THE HOSE CANNOT BE REPLACED. THE WHOLE PIPE HAS TO BE REPLACED AND I REPLACED MINE. MY RESEARCH REVEALED THIS IS A FAIRLY COMMON PROBLEM AND THAT THERE IS A TOYOTA SERVICE BULLETIN FOR THIS PROBLEM BUT IN THE BULLETIN THEY CLAIM IT'S FOR SEEPAGE OF OIL. OBVIOUSLY TOYOTA KNOWS THIS IS A PROBLEM AS THE NEW PART I ORDERED IS COMPLETE PIPE WITH NO HOSES. THE PART NUMBER FOR THE PIPE IS 15767. IS THIS SOMETHING THAT CAN BE FURTHER LOOKED INTO AS TO WHY THIS IS NOT A RECALL THAT TOYOTA SHOULD PROPERLY FIX? *TR

VAN SPONTANEOUSLY BEGAN LEAKING OIL. I BROUGHT IT INTO THE DEALER AND WAS TOLD THAT IT WAS THE VVT1 ACTUATOR HOSE. APPARENTLY THIS WAS PART OF A VOLUNTARY RECALL THAT TOYOTA STARTED IN 2010 AND I WAS NEVER NOTIFIED! I CALLED TOYOTA MOTOR CORPORATION AND WAS TOLD THAT THIS WAS IN FACT A DEFECTIVE HOSE BUT BECAUSE IT WAS NOT REPAIRED PRIOR TO THE 3/31/13 DEADLINE THAT TOYOTA WOULD NOT PAY FOR THIS DEFECTIVE HOSE TO BE REPLACED. I AM CERTAIN THAT I WAS NEVER NOTIFIED OF THIS VOLUNTARY AND WORRY THAT MANY OTHER 2008 SIENNA OWNERS ARE UNAWARE OF THIS DEFECTIVE PART AND HENCE WILL NOT HAVE THIS REPAIRED. THIS HOSE IS UNDER PRESSURE AND IF IT GOES COMPLETELY CAR WILL SPEW OIL EVERYWHERE AND SEIZE UP! THIS IS A POTENTIAL FIRE AND SAFELY HAZARD!!! TOYOTA IS VERY AWARE OF THIS PROBLEM! IN THE END MY DEALER AGREED TO...

I WAS DRIVING DOWN THE ROAD AND SAW SMOKE ROLLING OUT OF ENGINE. BY THE TIME I PULLED OVER I NOTICED OIL LEAKING OUT EVERYWHERE. IT WAS THE ENGINE OIL COOLER LINE AND I HAVE SINCE REPLACED THE RUBBER HOSE TWICE AND HAS RUPTURED TWO MORE TIME SINCE. THIS IS VERY DANGEROUS. I LOST OVER 12 QUARTS OF OIL IN THE LAST MONTH.

AFTER DRIVING VEHICLE FOR APPX. 15 MINUTES THEN PARKING, THEN COMING BACK TO VEHICLE 5 MINUTES LATER I FOUND A POOL OF OIL UNDER THE HOOD OF VAN AND CALLED FOR TOW TO THE DEALERSHIP. ROB FROM THE TOYOTA REPAIR SERVICE, CLAIMS I HAD BAD LUCK REGARDING THE OIL COOLER LINE RUPTURING. IT WILL COST ME $442.00 TO REPAIR/REPLACE AND CLEAN THE VEHICLE. AFTER HEARING THIS I CHECKED ONLINE AND OTHER VEHICLE OWNERS ARE HAVING SIMILAR PROBLEMS WITH SIMILAR VEHICLES THAT HAVE A V6 ENGINE WITH TOWING PACKAGE FROM TOYOTA. THE SERVICE PERSON CLAIMS ITS NOT COVERED UNDER MY WARRANTY. HE ALSO CLAIMS THAT IT WASN'T DAMAGED ACCIDENTALLY NEITHER.

WHILE DRIVING HOME THE OIL LINE RUNNING FROM THE OIL COOLER ON THE RADIATOR EXPLODED. OIL WAS SENT OVER THE ENTIRE ENGINE COMPARTMENT AND DRIPPED OVER THE ROAD LEAVING A TRAIL THE BLOCK LEFT GOING TO MY HOUSE. THE HOT OIL SPRAYING OVER THE HOT ENGINE WAS A DANGER TO CATCHING THE VAN AND THE GARAGE IT WAS PARKED IN ON FIRE. THIS IS AN EXTREMELY DANGEROUS PROBLEM THAT TOYOTA IS AWARE OF YET HAS NOT ISSUED A RECALL FOR THESE VEHICLES. I WAS LUCKY THAT THIS HAPPENED SO CLOSE TO MY HOME. *TR

WHILE DRIVING MY SIENNA AC QUIT & FEW MILES LATER I SAW WHITE SMOKE COME FROM UNDER THE VAN IN MY MIRROR. I TRIED TO SLOW DOWN & BRAKES WERE NOT WORKING. I TRIED TO PULL OVER & POWER STEERING WAS NOT WORKING. WITHOUT ANY WARNING LIGHTS. AFTER I PULLED OVER, I WALKED TO THE BACK TO SEE WHAT THE WHITE SMOKE WAS. I NOTICED THAT THE BUMPER COVER HAD MOTOR OIL DRIPPING DOWN FROM THE BUMPER & TAIL PIPE. I NOTICED THE WHITE SMOKE WAS ACTUALLY COMING OUT FROM THE FRONT RIGHT SIDE OF THE VAN. I RAN TO SHUT THE ENGINE OFF BUT I COULD NOT OPEN THE DRIVER SIDE DOORS. LUCKILY WINDOWS WERE OPENED DUE TO THE AC NOT WORKING. I TOOK THE KEY OUT THROUGH THE WINDOW & PULLED THE HOOD LATCH. BY THE TIME I GOT TO THE HOOD FLAMES WAS COMING FROM THE RIGHT...

WHILE PULLING INTO MY DRIVEWAY I SMELLED OIL AND NOTICED A LINE OF LIQUID DOWN THE DRIVEWAY. TURNS OUT THE OIL LINE RUPTURED AND THE ENGINE OIL DRAINED ALMOST COMPLETELY, WITHIN A MATTER OF MINUTES. THERE WAS NO WARNING INDICATOR OR ANYTHING ADVERSE UNTIL THAT MOMENT. THANKFULLY I LIVE NEAR A MECHANIC AND WE WERE ABLE TO LEAVE IT THERE. APPARENTLY THIS IS A KNOWN PROBLEM AT TOYOTA- AS THE PART WAS ON A NATIONAL BACKORDER. THANKFULLY I DID NOT SUFFER ENGINE DAMAGE- MANY OTHERS HAVE, AND THIS SHOULD BE A RECALL WORTHY ISSUE. *TR

WHILE DRIVING ARE 2008 SIENNA MINI VAN WITH 51303 MILES ON IT WE HAD DEVELOPED A SUDDEN LOSS OF OIL FROM THE ENGINE. NO CHECK ENGINE LIGHTS OR WARNING LIGHTS CAME ON NOTIFYING US THAT THERE WAS A PROBLEM. OBSERVED THAT THERE WAS A LARGE AMOUNT OF OIL LOSS IN THE DRIVEWAY. COULD TRACK BACK WHERE WE WERE DRIVING WITH THE OIL LOSS TRAIL IN THE ROAD. DID SOME RESEARCH AND LEARNED THAT THE ENGINE IN THE SIENNA IS THAT SAME AS THAT IN SEVERAL OTHER TOYOTAS (AVALONS). I LEARNED THAT THERE IS A VVI OIL LINE IS FAULTY ON THE ENGINE. TOYOTA USED A RUBBER HOSE WHICH RESULTS IN FAILURE WHICH THEN RESULTS IN ENGINE DAMAGE DUE TO THE OIL LOSS. TOYOTA RECALLED THE SAME PARTY ON THE AVALON AND IS AWARE THAT THIS HOSE IS BAD AND NEEDS REPLACEMENT. TOYOTA ISSUED RECALL ON THE AVALONS BUT IS NOT...

TL* THE CONTACT OWNS A 2008 TOYOTA SIENNA. THE CONTACT STATED THAT THE OIL LINE, WHICH TOYOTA CALLED THE VVT LINE BURST AND THE ALL OF THE OIL LEAKED OUT OF THE VEHICLE. THE CONTACT TOOK THE VEHICLE TO THE DEALER WHO CONFIRMED THE VVT LINE BURST AND CAUSED THE FAILURE. THE DEALER INFORMED THE CONTACT THAT THE PART WAS NOT UNDER WARRANTY NOR WAS THERE A RELATED RECALL. THE VEHICLE WAS REPAIRED. THE VIN WAS NOT AVAILABLE. THE FAILURE AND CURRENT MILEAGES WAS 51,303. *TR

ON A RAINY SUNDAY AFTERNOON I WAS DRIVING 65 MPH ON THE INTERSTATE WHEN THE CHECK ENGINE, VSC AND TRAC OFF LIGHTS CAME ON. THE VEHICLE WAS TAKEN DIRECTLY TO THE DEALER THE NEXT MORNING (69 ADDITIONAL MILES WERE DRIVEN). WHEN TESTED THE CODE INDICATED TO INSPECT THE VVT-1 SYSTEM, INCLUDING THE ACTUATOR BOLTS AND ALIGNMENT. UPON INSPECTION (REQUIRING THE ENGINE TO BE PARTIALLY DISASSEMBLED) IT WAS DETERMINED THAT THE VVTI GEAR WAS COMING APART CAUSING DEBRIS TO SPREAD THROUGHOUT THE CAMSHAFT GEARS AND HOUSING ONLY FOR CAM BANK 1. THIS IS AN OBVIOUS MATERIAL QUALITY DEFECT AND TOYOTA'S ONLY STATEMENT IS "WE DON'T HAVE A RECALL FOR THIS". MY VAN IS 90 DAYS PAST THE 5 YEAR & 17,369 MILES OVER THE 60,000 WARRANTY. (NOTE: OTHER MANUFACTURER'S OFFER A 100,000 POWERTRAIN WARRANTY). THIS VAN HAS ONLY BEEN SERVICED BY THIS DEALER. THIS SINGLE REPAIR BILL IS $4,295.00 WITH NO...

WHILE DRIVING ALOT OF SMOKE COMING OUT FROM ENGINE, PULLED OVER AND TURN OFF AND ALL CAME OUT OF CAR AND OIL STARTED LEAKING. NEXT DAY TOOK VAN TO THE TOYOTA DEALER AND THEY CHECKED EVERYTHING WAS FINE BUT THERE WAS A PART( OIL HOSE NO.1 ) THAT WAS BEEN RECALL AND IT BEEN FIX BY TOYOTA DEALER BUT SAME HOSE WAS BLOW WHICH IS DANGEROUS THAT TOYOTA DEALER TOLD US AND HE WAS SURPRISED THAT COULD NOT HAPPEN AFTER REPLACE PART THAT MEAN THEY STILL HAVE THAT SAME PROBLEM AND WE WAS ON I-10 , WE STOP THE VAN ON TIME OTHERWISE WE WONT ABLE TO MOVE VAN AND WE MIGHT LOST OUR LIFE SO PLEASE INVESTIGATE AND SAVE OTHERS LIFE . *TR

THERE WAS A PIN HOLE PUNCTURE IN THE FLEXIBLE MATERIAL THE OIL COOLER IS MADE OF. THE RESULT OF THIS IS THAT ALL THE OIL IS FORCED OUT OF THE ENGINE VERY QUICKLY UNDER HIGH PRESSURE. THERE WAS NO WARNING UNTIL I HEARD ENGINE NOISE. I HAD THE VAN TOWED IN AND HAD THE PART REPLACED. THE CURRENT FACTORY AUTHORIZED PART IS NOW MADE OUT OF METAL. THE DEALERSHIP THEN INFORMED ME THAT BECAUSE OF THE FAILURE OF THE PART I WOULD NEED A NEW ENGINE.IT WILL COST $10,000. I ASKED IF THERE WAS ANYTHING I COULD HAVE DONE DIFFERENTLY TO PREVENT THIS I WAS TOLD NO. MY ENGINE IS STILL UNDER WARRANTY BUT THE PART THAT CAUSED IT IS NOT. I REALIZE PARTS BREAK BUT THIS PART IS NOT A MAINTENANCE PART AND THE EXPECTED OUTCOME OF ITS FAILURE IS ENGINE REPLACEMENT. THIS I HAVE FOUND FROM EXPERIENCED AUTO...

WE HAVE OWNED THE SIENNA FOR 4 YEARS AND 53,000 MILES WITHOUT INCIDENCE. WE HAVE HAD IT SERVICED BY THE TOYOTA DEALER AND HAVE HAD ALL SCHEDULED MAINTENANCE. ONE AFTERNOON, AFTER DRIVING THE SIENNA ALL DAY, WE PULLED IT INTO OUR DRIVEWAY (WHICH IS ON A SLIGHT INCLINE) AND PLACED IT INTO PARK. AFTER DOING THIS, INSTEAD OF THE BRAKES BEING APPLIED, THE SIENNA ROLLED BACK AS THOUGH IT WERE IN NEUTRAL. WE BROUGHT THE SIENNA TO THE TOYOTA DEALER WHO INSPECTED IT. THEY TOLD US THE PIN THAT ENABLES THE BRAKES UPON PLACING THE SIENNA IN PARK WAS COMPLETELY SHOT AND THE ENTIRE TRANSMISSION WOULD NEED TO BE REPLACED. THE SERVICE MANAGER SAID HE HAS NEVER SEEN SOMETHING LIKE THIS BEFORE AND THAT THESE PINS DON'T WEAR OUT OVER TIME. THE SERVICE MANAGER ALSO TOLD US THAT YOU WOULD ONLY SEE DAMAGE TO THE PIN IF YOU WERE DRIVING...
