2008 Toyota Sienna Engine Problems

While pulling into a parking lot, you heard a ticking sound from the engine and discovered oil leaking underneath your vehicle. When you checked the oil level, the dipstick showed no oil remaining, but no warning light had appeared on the dashboard. Even after adding oil, the noise continued while driving. A dealer inspection revealed that the exhaust cam gear had cracked, causing damage to the engine and other components—requiring replacement of the engine, exhaust cam gear, timing chain, and additional repairs. The fix will involve a complete engine replacement along with related component repairs.

Your engine's head gasket, which was previously repaired, has failed again. Additionally, your radiator system has also failed. It's unclear whether these failures are due to how the dealer performed the initial repair or if they're manufacturing defects, especially since the previous owner had the vehicle serviced at a Toyota dealership before trading it in. You'll likely need a head gasket replacement and radiator system repair or replacement.

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.

2008 TOYOTA SIENNA. CONSUMER WRITES IN REGARDS TO VEHICLE ENGINE PROBLEMS. *SMD THE CONSUMER STATED THE AIR CONDITION WAS NOT COOLING THE VEHICLE, AND SHE THOUGHT IT JUST NEEDED TO BE SERVICED. AFTER TWO HOURS OF DRIVING, THE CHECK ENGINE LIGHT ILLUMINATED. BY THE TIME SHE WAS ABLE TO PULL OVER, THE ENGINE WAS RUINED, THE DEALER STATED THE ENGINE WATER HOSE AND OIL HOSE HAD MALFUNCTIONED. *JB

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 HAVE CAUGHT FIRE? WE HAVE A VAN FULL OF CHILDREN, AND IT'S FRIGHTENING TO THINK THAT THIS COULD HAVE ENDED MUCH WORSE.

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 A SUDDEN BURST AND CAUSED THE OIL TO LEAK OUT LIKE A RUNNING FAUCET. WE WERE EXTREMELY FORTUNATE BECAUSE IT OCCURRED JUST WHILE SHE WAS DRIVING THE VAN IN OUR SUBDIVISION. TOYOTA HAD AN EXTENDED WARRANTY FOR THIS ISSUE LAST SUMMER BUT DIDN'T HAVE A RECALL FOR THIS. IF IT HAPPENED WHILE WE WERE DRIVING ON HIGHWAY AND WE DIDN'T PAY ATTENTION TO THE ENGINE LIGHT, THE ENGINE MAY BURN OR WORSE IT COULD SEIZE AND CAUSE ACCIDENT. AFTER A LITTLE RESEARCH ON THE WEB, I FOUND OUT THERE ARE A LOT OF PEOPLE HAD THIS SAME ISSUE. TOYOTA ACTUALLY HAD A RECALL OTHER MODELS OF CARS FOR THE SAME ISSUE SEVERAL YEARS AGO. I WONDER WHY THEY DIDN'T RECALL THE 2008 SIENNA AND THEY SHOULD HAVE. I WANT TO REPORT THIS AND HOPEFULLY FORCE TOYOTA TO START RECALL ON THIS ISSUE FOR ALL IMPACTED MODELS SO OTHERS WON'T HAVE TO EXPERIENCE THIS AND AVOID POTENTIAL ACCIDENTS. THANKS. *TR

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

TL* THE CONTACT OWNS A 2008 TOYOTA SIENNA. THE CONTACT STATED THAT WHITE SMOKE APPEARED FROM THE REAR OF THE VEHICLE. THE CONTACT HEARD AN ABNORMAL NOISE COMING FROM THE ENGINE, BUT NO WARNING INDICATORS ILLUMINATED. AFTER DRIVING THE VEHICLE HOME, THE CONTACT NOTICED THAT OIL SPILLED ALL OVER THE DRIVEWAY, HOOD OF THE VEHICLE, AND THE FRONT PASSENGER SIDE TIRE. THE VEHICLE WAS TOWED TO THE DEALER WHO STATED THAT THE OIL COOLER SUPPLY LINE BURST. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 74,000.

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 EXTRA $$ ON HOTELS AND A RENTAL CAR. BUT IT COULD HAVE BEEN MUCH WORSE - THE OIL COULD HAVE DRAINED WHILE AT SPEED ON THE HIGHWAY, RUINING THE ENGINE, STRANDING MY FAMILY IN AN ISOLATED AREA OR CAUSING AN ACCIDENT OR ENGINE FIRE AND POSSIBLE INJURIES. GIVEN THAT TOYOTA WAS AWARE OF THE PROBLEM, IT COULD HAVE INFORMED US SO WE COULD HAVE HAD THE HOSE REPLACED BEFORE IT FAILED. *TR

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

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 DID NOT COME ON. *TR

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 COVER THE COST OF REPLACEMENT, BUT I AM FOREVER DISMAYED AT TOYOTA'S LACK OF CONCERN FOR THEIR CUSTOMERS! THIS WAS PART OF CAMPAIGN RECALL 90K-2GR-FE V6 ENGINE OIL HOSE. *TR

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 SIDE. I COULD NOT OPEN THE HOOD, IT WAS TOO HOT. THIS HAPPENED IN MATTER OF SECONDS. BE AWARE THAT ALL THIS HAPPENED WITHOUT ANY WARNING SOUND?S OR LIGHT?S. I CALLED 911. JUST IN MINUTES, THE VAN WAS ENGULFED IN FLAMES & I HAD NO CHANCE TO SAVE ANYTHING OUT OF THE VEHICLE. THE FIRE TRUCKS ARRIVED ABOUT 9 MINUTES, BUT BY THAT TIME THERE WAS NOTHING LEFT OF MY VAN. THE FIREMAN POINTED OUT TO ME THAT THERE WAS AN OIL TRAIL BEHIND THE VAN. THE OIL TRACE WAS VISIBLE FOR FEW MILES. AFTER THEY FINISHED PUTTING OUT THE FIRE THEY SHOWED ME WHERE THE FIRE STARTED ON THE VAN. IT WAS THE AREA ON THE LEFT SIDE OF THE ENGINE AROUND THE BELT. THEY SAID THAT THE FIRE STARTED FROM AN OIL LEAK ON THE ENGINE AND WAS STARTED BY THE BURST OF OIL SPRAYING DOWN ON THE AND CATALYTIC CONVERTER. ONLY TWO SECONDS OF SEARCHING ON GOOGLE, I FOUND OUT THAT TOYOTA IS WELL INFORMED OF THE HAZARDOUS DEFECT. THE RUBBER OIL SUPPLY LINE UNEXPECTEDLY BURST OPEN AND SPRAY?S THE ENGINE OIL OUT IN LESS THAN FEW MINUTES. I NEVER RECEIVED ANY RECALLS OR NOTIFICATION ABOUT THIS SERIOUS DEFECT FROM TOYOTA. LUCKILY NONE OF MY THREE KIDS WAS NOT IN THE VAN WHEN THIS HAPPENED. *TR

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 ISSUING A RECALL ON THE SIENNA. THIS IS THE SAME PIECE ON THE TWO VEHICLES. THEY THEN STATE THAT THIS HOSE WITH AN AVERAGE FAILS AT 50-60000MILES. THEY THEN STATED THAT THIS HOSE IS NOT COVERED UNDER WARRANTY. THIS HOSE BURSTING CAN CAUSE ENGINE DAMAGE AND IS ALSO A SAFETY ISSUE. THERE NEEDS TO BE A RECALL ON THIS RUBBER OIL HOSE ON ALL VEHICLES. THEY KNOW THAT THIS IS A BAD PIECE WHEN TALKING WITH THEM. ALSO IF IT WERE TO FAIL THEY THEN WILL STATE THAT SINCE THIS HOSE CAUSED THE ENGINE ISSUES THEY WILL NOT COVER IT UNDER WARRANTY. THIS THEN RESULTS IN PEOPLE HAVING TO REPLACE THE ENGINE IN THERE VEHICLE FOR 5-10000DOLLARS. WHEN OIL LOSS OCCURS IT SPRAYS EVERY WHERE GETTING ON BRAKES, BELTS, AND EXHAUST WHICH COULD CAUSE AN ACCIDENT AND OR FIRE. ALSO RESULTING IN SERIOUS ENGINE DAMAGE. TOYOTA KNOW THIS VVI HOSE IS BAD AND ISSUED A RECALL ON THE SAME HOSE ON THE AVALONS. A FIVE MINUTE SEARCH ON THE INTERNET WILL SHOW YOU THE ISSUES WITH MOTOR AND VVI HOSE. A RECALL MUST BE ISSUED ON ALL TOYOTA VEHICLES WITH THIS MOTOR WHICH HAD THE VVI OIL HOSE. THANKS *TR

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

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 PEOPLE IS COMMON KNOWLEDGE. I BELIEVE THIS IS A DEFECT THAT TOYOTA KNOWS ABOUT AND IS WILLING TO IGNORE BY INVOKING THEIR WARRANTY AS A REASON TO ALLOW THIS TO HAPPEN TO UNSUSPECTING OWNERS. OH, WHEN I CONTACTED TOYOTA FOR HELP WITH MY $10,000 PROBLEM, THEY OFFERED ME DINNER. AT THIS POINT I OWN A $30,000 PIECE OF JUNK ( I OWE $20,000) NONE OF THIS WOULD HAVE OCCURRED IF THE PART HAD BEEN MADE OUT OF METAL ORIGINALLY OR IF THERE WAS SOME KIND OF SAFEGUARD BUILT IN TO WARN YOU OF THE POTENTIAL PROBLEM. UNFORTUNATELY THAT IS NOT THE CASE. PLEASE HELP. *TR

TL* THE CONTACT OWNS A 2008 TOYOTA SIENNA. THE CONTACT STATED THAT WHILE DRIVING 55 MPH, SMOKE BEGAN TO EMIT FROM THE REAR. THE CONTACT STOPPED THE VEHICLE AND NOTICED THAT A HIGH PRESSURE HOSE UNDER THE INTAKE MANIFOLD WAS PIERCED AND LEAKING OIL. THE VEHICLE WAS TOWED TO AN INDEPENDENT REPAIR SHOP AND WAS IN THE PROCESS OF BEING EVALUATED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND OFFERED NO ASSISTANCE. THE FAILURE MILEAGE WAS 40,105. UPDATED 4/2/12 *CN

AT HIGHWAY SPEED, ALL LIGHTS FLICKER ON THEN LOST ALL POWER.......OILLINE HAD LEAKED ON ALTERNATOR BELT CAUSING LOSS OF POWER. LUCKILY POWER LOSS PREVENTED ENGINE DAMAGE FROM OIL LEAK. WE HAD NOT BEEN NOTIFIED BY TOYOTA ABOUT THE OIL LINE PROBLEM OR RECALL.....ONLY AFTER A LOCAL GARAGE FIXED THE LINE DID I FIND OUT ABOUT THE RECALL....I WOULD HAD IT REPLACED EARLIER IF I HAD BEEN NOTIFIED. *TR

TL* THE CONTACT OWNS A 2008 TOYOTA SIENNA. WHILE DRIVING 65 MPH, THE CONTACT STATED THAT THEA PUSH ROD FRACTURED CAUSING A HOLE IN THE ENGINE. THE VEHICLE WAS TOWED TO THE DEALER WHERE HE WAS INFORMED TO REPLACE THE ENGINE. THE MANUFACTURER WAS AWARE OF THE FAILURE. THE CURRENT AND FAILURE MILEAGE WAS 60,600. NO REPAIRS WERE PERFORMED.

TL* THE CONTACT OWNS A 2008 TOYOTA SIENNA. WHILE DRIVING APPROXIMATELY 65 MPH, THE ENGINE STALLED WITH THE ILLUMINATION OF THE ENTIRE INSTRUMENT PANEL. THE VEHICLE FAILED TO RESTART AND WAS TOWED TO AN AUTHORIZED DEALER FOR DIAGNOSTIC TESTING. THE TECHNICIAN WAS UNABLE TO DETECT A TROUBLE CODE. THE MALFUNCTION OCCURRED SIX TIMES ON THE SAME DAY. THE ENGINE RESTARTED EACH TIME THE FAILURE OCCURRED AND THE VEHICLE WAS TAKEN TO A DIFFERENT DEALER WHO COULD NOT LOCATE A PROBLEM. THE CONTACT PLANNED TO TAKE THE VEHICLE FOR A THIRD OPINION TO POSSIBLY LOCATE THE CONSISTENT FAILURE. THE MANUFACTURER WAS NOTIFIED OF THE PROBLEM. THE APPROXIMATE FAILURE MILEAGE WAS 34,680.

2008 TOYOTA SIENNA WITH APPROX. 45K MILES. DRIVING DOWN HIGHWAY AFTER WEDDING. TRACTION CONTROL LIGHT COMES ON. A MINUTE LATER, CHECK ENGINE LIGHT COMES ON. HALF MILE FROM EXIT, DECIDE TO TAKE EXIT TO SEE WHAT'S GOING ON. AS REACH GAS STATION RIGHT OFF EXIT, OIL LIGHT COMES ON. CHECK OIL AND SEE NO OIL IN ENGINE. OIL SPLASHED ON TAILGATE. DETERMINE OIL FLOWING FROM ENGINE. TOYOTA ACKNOWLEDGED PROBLEM WITH RUBBER OIL HOSE AND SENT TOW TRUCK. LOSS OF ALL OIL WITHOUT INDICATION UNTIL ENGINE FAILURE. SAME V6 ENGINE AS RECALLED IN CAMRY AND AVALON. THIS IS A SERIOUS PROBLEM REQUIRING COMPLETE ENGINE REPLACEMENT. THIS IS UNSAFE--SUDDEN ENGINE FAILURE WITHOUT INDICATION AT HIGHWAY SPEEDS AND OIL SPILL TO EXHAUST COMPONENTS OF ENGINE COULD HAVE CAUSED ACCIDENT OR FIRE!

1. ENGINE LIGHTS CAME ON ALERTING US TO A PROBLEM (CHECK ENGINE, SERVICE ENGINE, ETC.). AFTER ALLEGED REPAIR, SPOUSE DROVE TO FAMILIES HOUSE APPROXIMATE 600 MILES AWAY AND FOUND A SIGNIFICANT AMOUNT OF OIL HAD LEAKED FROM THE SYSTEM - OIL HAD BEEN CHANGED AS PART OF THE FIX. A SECOND DEALER, AT THE NEW LOCATION, "FIXED" WITH THE SAME HOSE AGAIN, WITH SIMILAR RESULTS, THOUGH MY SPOUSE ONLY DROP 120 MILES. SHE IS UNABLE TO CONTINUE THE TRIP HOME DUE TO THIS ISSUE. 2. AFTER TAKING TO DEALER, WAS TOLD THE VVT OIL LINE WAS A KNOWN FAULTY PART AND NEEDED REPLACEMENT. WAS NOT A "FORMAL" RECALL, BUT WAS CONSIDERED AN INTERNAL RECALL TO TOYOTA THAT NEEDED TO BE FIXED FOR "FREE". BOTH DEALERSHIPS CLAIMED TO HAVE FIXED THE PROBLEM, THOUGH THE ENGINE IS STILL LEAKING A SIGNIFICANT AMOUNT OF OIL. THERE IS A SIGNIFICANT AMOUNT OF DATA ON THE WEB THAT ADDRESSES THIS OIL LINE AND THE ASSOCIATED ISSUES. 3. PART WAS REPLACED, BUT WITH SAME TYPE (PART NUMBER, COMPOSITION, ETC.). BASICALLY, A "NEW" BAD PART WAS REPLACED. FURTHERMORE, THE FIRST DEALERSHIP INSTALLED VARIOUS GASKETS AND SEALS INCORRECTLY, AND STILL GAVE THE CAR A SAFE RATING FOR A 600 MILE TRIP. THE SECOND DEALERSHIP MERELY REPLACED A BAD OIL LINE WITH ANOTHER BAD OIL LINE. *TR

IN THE SUMMER OF 2009 MY TOYOTA 2008 SIENNA XLE AWD ENGINE SPEED SLOWLY STARTED TO CLIMB WITHOUT MY FOOT ON THE GAS PEDAL. I DON'T REMEMBER THE EXACT SEQUENCE OF EVENTS THAT FOLLOWED BUT I BELIEVE I PLACED IT INTO NEUTRAL, STOPPED, PLACED IT INTO PARK (AUTOMATIC TRANSMISSION) AND TURNED THE ENGINE OFF THEN ON AGAIN. AFTER THAT THE ENGINE RESPONDED ONLY TO MY ACTIONS ON THE GAS PEDAL. IT DID OCCUR TO ME THAT THE PEDAL COULD HAVE BEEN CAUGHT UNDER THE FLOOR MAT SO I CHECKED ITS POSITION AND IT WAS SOME DISTANCE FROM THE PEDAL AND COULD NOT HAVE BEEN THE CAUSE. I HAVE OWNED THIS VEHICLE FROM NEW IN MAY 2008 AND THIS UNDIRECTED ACCELERATION HAS ONLY OCCURRED ONCE. THE CAR HAS JUST COMPLETED 20,000 MILES. I REPORTED THIS TO THE DEALER WHO SERVICED MY CAR FOR THE 20,000 MILE INTERVAL AND VIA TOYOTA'S WEB SITE BUT I WANT TO MAKE SURE YOU ARE AWARE THAT SIENNA VANS CAN ALSO HAVE THIS PROBLEM. *TR

EARLY AM ON 6/1/10 I WAS DRIVING TO MY CABIN IN THE COUNTRY AND HEARD A SOFT POPPING SOUND, STOPPED MY CAR AND SMOKE BEGAN FLOWING OUT ALL OPENING AROUND THE HOOD, WHEN I LOOKED UNDER THE CAR I SAW FIRE FALLING TO THE ROAD. I WENT TO THE PASSENGER SIDE AND OPENED THE DOOR ONLY TO FIND THAT AREA FILLED WITH TOXIC FUMES, SHUTTING THE DOOR I REALIZED ALL WAS HOPELESS EXCEPT TO GET AWAY FROM THE VEHICLE. WITHIN SECONDS MY CAR WAS ENGULFED IN FLAMES. I RAN AS FAST AS I COULD TO GET HELP. HAD I BEEN LESS ALERT, INACTIVE, LESS PROACTIVE I WOULD HAVE PROBABLY DIED. THE CAR WAS PURCHASED NEW IN NOV, 2008 AND HAD A LITTLE OVER 10,000 MILES. THERE WAS NO SMELL OF FUEL OR ANOTHER STRANGE ODOR. THE CAR WAS BURNED TOTALLY, WITH NOTHING REMAINING EXCEPT THE STEEL FRAME. *TR

DRIVING MY 2008 TOYOTA SIENNA AND IT FELT FUNNY AND I HEARD SOME RATTLING FROM UNDER THE HOOD. NO IDEA WHAT THE PROBLEM WAS BUT I KNEW THAT SOMETHING WAS DEFINITELY WRONG. I CHECKED THE OIL AND THE DIP STICK WAS COMPLETELY DRY! I PUT IN A FEW QUARTS OF OIL AND IT CAME OUT ALL OVER UNDERNEATH THE CAR AS I WAS DRIVING. HAD IT TOWED TO THE DEALER- THEY TOLD ME IT WAS A FAULTY RUBBER OIL LINE. I LOOKED IT UP ONLINE AND SEE THAT TOYOTA HAD NOT YET ISSUED A RECALL BUT IS REPLACING IT IN SOME VEHICLES. THE 2008 TOYOTA SIENNA IS NOT MENTIONED - BUT CLEARLY SHOULD BE. THIS IS A VAN THAT I DRIVE MY 2 CHILDREN AROUND - VERY CLEARLY A SAFETY ISSUE IF I DID NOT RECOGNIZE SOON ENOUGH THAT THE ENGINE HAD NO OIL! *TR

PISTON SLAP ON TOYOTA 3.5 L V6 SINCE NEW. VERY LOUD WHEN COLD IN COOLER TEMPERATURES..CA ARBITRATOR AGREES WITH TOYOTA THAT THIS IS NORMAL FOR THIS ENGINE. I CANNOT SELL THIS CAR WITH THIS NOISE BUT TOYOTA DOESN'T CARE. TOYOTA HAS HAD A FEW COMPLAINTS BUT NO FAILURES YET. PISTON SLAP WEARS THE PISTON PREMATURELY AND COULD IN MY OPINION LEAD TO FAILURE. THIS IS MY 2ND COMPLAINT TO YOU PEOPLE FOR THE SAME ISSUE. *TR
