2007 Toyota Sienna Engine Problems

The rubber part of the VVT-I oil line appears to worn and leaking. There is a Toyota Campaign to replace this faulty designed oil line with a full metal line, but for some reason my 2007 Toyota Sienna VIN is not showing up with this campaign. The oil will leak from the engine and cause failure. Please re-check which vehicles are impacted by this Toyota design problem in this VVT-I oil line.

OIL LINE RUPTURED DUE TO RUBBER FAILURE. THIS OIL LINE WAS REPLACED IN 2012 WITH SAME LINE AS ORIGINALLY INSTALLED. FAILURE CAN BE CATASTROPHIC FOR ENGINE AS OIL IS DISCHARGED QUICKLY AND WITH NO WARNING OR INDICATION. VEHICLE WAS IN MOTION ON A HIGHWAY WHEN ODOR AND NOISE MADE ME STOP AND CHECK. HAD TO BE TOWED AND REPAIRED. COST OVER 500.00.

OIL COOLING HOSE BROKE AND ALL ENGINE OIL LEAKED FROM ENGINE. VEHICLE WAS IN MOTION BUT MADE TO PARKING SPOT. NO WARNING OF EVENT AND NO DASH/ENGINE LIGHT SIGNALING PROBLEM. ONLY OIL ON GROUND UNDER VAN SIGNALED PROBLEM. VAN WAS SUBJECTED TO RECALL IN 2011 WHICH REPLACED HOSE. DEALER REPLACED PARTS AS REPAIR WITH A COMPLETE REDESIGNED PART REMOVING RUBBER HOSED ALL TOGETHER. THIS WAS NOT A RECALL BUT OWNERS EXPENSE. MANUFACTURER NEVER NOTIFIED OWNER OF THIS DEFECTIVE PART OR EVENT POSSIBILITY.

I WAS DRIVING BACK FROM THIS WEEKEND ON A HIGHWAY AND I NOTICED A THUMPING NOISE COMING FROM THE FRONT OF THE VEHICLE AND THEN I NOTICED AN ENGINE LIGHT CAME ON AND INSTINCTIVELY I KNEW THAT WAS A BAD SIGN FOR ALL SIX OF US MY FAMILY AND FRIENDS. SO I IMMEDIATELY EXITED THE NEAREST EXIT RAMP AND THAT'S WHEN THE ENGINE STALLED AND I COULDN'T MOVE ANY LONGER. WE CALLED OUR INSURANCE COMPANY FOR TOWING AND THE COPS TO STEER CLEAR OF ONCOMING TRAFFIC SINCE WE'RE ON THE SECOND LANE ON THE EXIT RAMP. I THANK GOD THAT NOTHING HAPPENED TO US BUT IT SHOULDN'T HAPPEN TO MY VEHICLE WITH ONLY 93,000 MILES WITH REGULAR MAINTENANCE AND A CLEAN DRIVING RECORD.

2007 TOYOTA SIENNA OIL COOLER LINE LINE HAS A PINHOLE LEAK NEVER INDICATES THAT THERE IS NO OIL OR LOW OIL PRESSURE

TL* THE CONTACT OWNS A 2007 TOYOTA SIENNA. WHILE DRIVING 25 MPH, THERE WAS AN ABNORMAL GRINDING NOISE AND A BURNING ODOR IN THE VEHICLE. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC. THE VEHICLE WAS TOWED TO A LOCAL DEALER (BURNSVILLE TOYOTA, 14790 BUCK HILL RD, BURNSVILLE, MN 55306) WHERE IT WAS DIAGNOSED THAT THE OIL COOLANT LINE NEEDED TO BE REPLACED AND THERE MAY BE ENGINE DAMAGE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE ISSUE AND INFORMED THE CONTACT THAT THE VEHICLE WAS NOT COVERED UNDER A RECALL OR WARRANTY. THE FAILURE MILEAGE WAS 121,766.

OIL COOLING HOSE RUPTURED WHILE DRIVING THE CAR AT APPROX. 60 MPH ON THE HIGHWAY. BLACK SMOKE BEGAN TO POUR OUT THE BACK OF THE CAR. OIL SPRAYED OVER THE ENGINE AND UNDERSIDE OF THE CAR AND RENDERED THE CAR UNDRIVABLE. DAMAGE ALSO SUSTAINED TO THE DRIVE BELT TENSIONER SYSTEM.

I WAS TOLD TODAY THAT MY COOLER HOSE RUPTURED AND I HAD TO TAKE IT IMMEDIATELY TO A AUTO REPAIR SHOP. I WAS DRIVING TO WORK AND THE CAR STARTED MAKING A CLICKING NOISE AND FELT WEIRD TO DRIVE. I GOT TO WORK AND WAS TOLD TO CHECK THE DIP STICK. WAS TOLD IT SOUNDED LIKE I HAD NO OIL. I WAS THINKING, THAT WOULDN'T BE RIGHT I JUST GOT AN OIL CHANGE ABOUT A WEEK EARLIER. IT WAS BARE. COMPLETELY EMPTY. I THEN PROCEEDED TO GET IT TO A REPAIR SHOP AS IT WAS AN EMERGENCY. THE AUTO PLACE TOLD ME THAT IT NEEDED A KIT THAT THEY WOULD HAVE TO BUY TO REPLACE THE COOLER HOSE AND WOULD TAKE AWHILE TO FIX THIS. IT WOULD BE THE ONLY WAY TO FIX THIS. AND THEY CANT GUARANTEE ME THE ENGINE DIDNT GET EFFECTED BY THIS SITUATION. I DID MY RESEARCH ON THIS ISSUE AND IT IS EXTREMELY DANGEROUS AND EXPENSIVE. I AM NOW OUT $500 AND HALF A DAY AT WORK. I WAS DRIVING TO WORK AT 7:15AM ON HIGHWAY 44 GOING ABOUT 45-55 MILES AN HOUR. IT WAS TERRIFYING AND ONCE I GOT TO MY WORK AND REALIZED THAT MY VAN COULD HAVE STOPPED ON ME IN THE MIDDLE OF TRAFFIC WHENEVER IT WANTED TO THIS MORNING OR THE ENGINE COULD HAVE BLOWN UP AND CAUSE A REAL ACCIDENT. THIS IS A SERIOUS DANGER TO ME AND PEOPLE AROUND ME. I HAD NO CLUE I WAS IN DANGER, I HAD NO IDEA THAT MY VAN WAS MESSED UP. THERE WERE NO SIGNS, NO PROBLEMS, NO ANYTHING. IT JUST OUT OF NOWHERE DRAINED THE OIL. I DRIVE 35-45 MILES TO WORK. I WISH I WOULD HAVE KNOWN ABOUT A "RECALL" ON THIS. I WOULDN'T HAVE HAD IT CHECKED WAY BEFORE.

WHEN ACCELERATING THE ENGINE MAKES A TRACKING NOISE LIKE BAD VAVLE SPRINGS OR CAMPS. ONLY HEAR THE NOISE WHEN ACCELERATING. STARTED HAPPENING AFTER 60K MILES. COMMON PROBLEM WITH THE ENGINE TOYOTA USES WITH THE SIENNA.

TOYOTA SIENNA 07 TO 13 HAS OIL COOLER HOSE LEAKAGE PROBLEM,CAUSE IT MADE OF RUBBER AND ALUMINUM,RUBBER PART OF THIS CAUSE LEAKAGE,BECAUSE ENGINE OIL GOES FROM IT WITH PRESSURE AND AFTER SOME TIME RUBBER PART GOES BAD AND START LEAKING WHEN YOU START THE VAN IT COMES OUT,IT HAPPENS WITH ME TWICE,FIRST MY 07 SIENNA HAS HAPPENS I BUY A USED PIPE FROM JUNK YARD AND FIX IT,AFTER FIFTEEN TWENTY DAYS IT HAPPENS AGAIN,ALL OF A SUDDEN ON A FREE WAY MY VAN HEAT UP IN LEFT LANE AND STOP ENGINE,I ALMOST GOT KILLED FOR THIS SUDDEN STOP,VAN HAS NO OIL LEFT IN ENGINE AND IT HEATS UP,I PULL MY VAN ASSIDE AND FIND OUT THAT ENGINE OIL COOLER PIPE IS OFF THE HOOK AND I AM OUT OF ENGINE OIL,HOW I COME BACK ITS A DIFFERENT STORY,BUT WHEN I CALL TOYOTA DEALER SHIP FOR RECALL THEY TOLD ME THIS IS NOT A SAFETY REASON SO L HAVE TO FIX IT MYSELF,MY QUESTION IS THAT FOR THERE CHEAP MATERIAL PIPES I CAN GOT KILLED,MY ENGINE CAN GO BAD,BUT THIS IS NOT A SAFETY ISSUE FOR THEM,CAN SOME ONE HELP ME.

DRIVING CAR IN TOWN FOR ABOUT 10 MINUTES. STOPPED AT FRIENDS HOUSE AND NOTICED WHEN I BACKED OUT A LARGE OIL PUDDLE. GOT OUT AND LOOKED UNDER CAR TO SEE UNDERCARRIAGE COVERED IN OIL FROM FRONT OF CAR TO MIDWAY DOWN CAR. COULD NOT TELL WHERE IT WAS COMING FROM SO I CALLED TOW TRUCK TO TAKE TO TOYOTA DEALERSHIP. THEY FOUND SMALL HOLE IN OIL COOLER LINE WAS SPRAYING OIL OUT. IT WAS HALF EMPTY OF ALL ITS OIL IN THAT SHORT AMOUNT OF TIME. THE DEALERSHIP TOLD ME IT WAS GOING TO COST ME $360.00 TO REPLACE OIL COOLER LINES. I WAS VERY LUCKY I HAD NOT DRIVEN VERY FAR OR PROBABLY WOULD HAVE BEEN CATASTROPHIC ENGINE FAILURE. AFTER QUICK CHECK ON INTERNET, THIS APPEARS TO BE A COMMON ISSUE WITH OIL SUPPLY LINES IN THIS AND OTHER MODEL YEARS. ALSO LOOKS LIKE THERE IS A NEW ALL METAL OIL SUPPLY LINE AND A WARRANTY EXTENSION (ZE2), NEITHER OF WHICH I WAS MADE AWARE OF BY MY DEALERSHIP AND WAS VERY DIFFICULT FOR ME TO FIND.

OIL COOLER PIPER RUPTURED AFTER STARTING AND DRIVING THE VEHICLE CAUSING RAPID OIL LOSS WHILE BEING DRIVEN TO WORK. IF I DID NOT NOTICE THE PUDDLE OF OIL LEFT BY MY WIFES CAR SHE WOULD HAVE DRIVEN IT HOME AND SURELY BLOWN THE ENGINE. THE PART WAS REPLACED IN 2010 DURING LIMITED SERVICE RECALL BUT STILL BURST 5 YEARS LATER.

I BELIEVE THE PRODUCT TO BE DEFECTIVE BECAUSE OF THE ISSUE THAT I HAD FACED WITH THIS VEHICLE 2 WEEKS BACK WHILE DRIVING IN THE FREEWAY. TWO WEEKS BACK WHILE I WAS DRIVING WITH MY FAMILY (WIFE AND 2 KIDS) THE VEHICLE ON 275 S FREEWAY @ 70MPH ON 8TH MARCH 2015 1:00 AM, THE ENGINE CHECK LIGHT TURNED ON AND I NOTICED THE ENGINE HEAT INDICATOR FLUCTUATE LIKE A FUEL INDICATOR. I TRIED TO SLOW DOWN, BUT BY THAT TIME I LOST THE POWER OF THE VEHICLE , WHICH MADE IT REALLY HARD FOR ME TO STEER THE VEHICLE BETWEEN THE LANES AND TAKE IT OUT OF FREEWAY TO A SHOULDER, THE BRAKES WERE NOT FUNCTIONING EITHER. IT WAS ONE OF MY SCARIEST RIDE I HAD IN MY LIFE (YOU CAN IMAGINE YOURSELF, ENGINE LOOSING POWER WHILE DRIVING IN A FREEWAY, I WAS WITH MY ENTIRE FAMILY, AND NOT HAVING CONTROL ON THE VEHICLE), IT PUT ME AND MY FAMILY AT SUCH A BIG RISK. GLAD I WAS ABLE TO SOME HOW TAKE THE VEHICLE OUT OF THE FREEWAY AND USED THE PARKING BRAKE TO BRING THE VEHICLE TO A STOP AT A FREEWAY SHOULDER @ 8 MILE ROAD EXIT. THE NEXT DAY, I TOOK THE VEHICLE TO VICTORY TOYOTA OF CANTON, A TOYOTA DEALER FOR DIAGNOSIS. AFTER THOROUGH DIAGNOSIS FROM THE DEALER, HE FIGURED OUT THE ENGINE WATER PUMP FAILED, WHICH LEAD TO THE ENGINE GETTING OVERHEATED AND ENGINE GOT DAMAGED, WHICH NEEDS TO BE REPLACED. THEY CAME BACK WITH THE COST OF 10,000 USD FOR FIXING THE VEHICLE. THE VEHICLE HAS ONLY 66,860 MILES ON THE ODOMETER. *TR

THE FRONT LOWER OIL COOLER PRESSURE HOSE (TOYOTA PART NO. 15767 31010) STARTED SPRAYING OIL OUT WHILE THE VAN WAS BEING DRIVEN UNDER NORMAL OPERATING CONDITIONS IN A RESIDENTIAL NEIGHBORHOOD WITH YOUNG CHILDREN IN THE CAR. HAD THIS OCCURRED AT A HIGHER SPEED (ON A HIGHWAY), ALL THE OIL WOULD HAVE SPRAYED OUT AND THE ENGINE WOULD HAVE SEIZED. THIS COULD HAVE CAUSED AN ACCIDENT OR THE VAN COULD HAVE CAUGHT ON FIRE. THIS IS A WELL KNOWN PROBLEM WITH THIS PART THAT TOYOTA HAS DONE ALMOST NOTHING TO FIX OR PREVENT. WE WERE EXTREMELY FORTUNATE TO HAVE DISCOVERED THIS PROBLEM IMMEDIATELY. *TR

THE OIL PUMP ASSEMBLY FAILED. IT WAS PARTIALLY MADE WITH A RUBBER HOSE THAT DID NOT PERFORM AS IT SHOULD. IT NEEDED TO BE REPLACED WITH A SOLID METAL PART. ALTHOUGH THERE WAS A SAFETY/SERVICE BULLETIN LISTED BY TOYOTA ON THIS PART IT COST ALMOST $1200 TO REPAIR.

I HAD A CATASTROPHIC LOSS OF OIL FROM THE UNDERNEATH OF THE CAR, THERE WAS A RECALL ON THIS PROBLEM WHICH WAS FIXED BACK IN 2011 BUT ALMOST EVERY ONE ONLINE THAT HAS HAD THIS FIX HAS TO GET IT DONE AGAIN. TOYOTA ARE NOT SEEKING THE FIX THE PROBLEM AGAIN WITH A METAL HOSE AND WE ARE HAVING TO PAY FOR THE REPLACEMENT.

TL* THE CONTACT OWNS A 2007 TOYOTA SIENNA. WHILE DRIVING APPROXIMATELY 20 MPH, FLAMES APPEARED UNDERNEATH THE ENGINE COMPARTMENT WITHOUT WARNING. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 99,000.

MY WIFE WAS DRIVING OUR 2007 TOYOTA SIENNA ON A MAJOR ROAD WHEN SHE NOTICED SMOKE COMING FROM UNDER IT. SHE PULLED INTO A PARKING LOT AND SHUT THE ENGINE OFF, AVOIDING ENGINE SEIZURE BECAUSE WITHIN JUST A COUPLE OF MINUTES IT HAD LOST 2 QTS OF OIL ONTO THE GROUND DUE TO A RUPTURE IN A RUBBER OIL VVT-1 LINE. AFTER READING ONLINE I FOUND OUT THIS IS A VERY COMMON PROBLEM WHICH TOYOTA HAS REFUSED TO ADDRESS PROPERLY. IN 2009 SIENNAS THE LINE HAVE BEEN SWITCHED TO ALL METAL LEAVING THE REST OF THEIR EARLIER CUSTOMERS WITH TICKING TIME BOMBS. THIS TYPE OF FAILURE IS UNACCEPTABLE, AN ENGINE SEIZURE AT 70MPH WILL BE DEADLY AND THE SPILT OIL ON THE ROAD POSSES HAZARDS AS WELL. A TOYOTA DEALERSHIP WANTS TO CHARGE OVER $500.00 TO REPLACE THIS $23.00 HOSE. *TR

WHILE TRAVELING AT 75MPH ON INTERSTATE, I NOTICED HEAVY WHITE SMOKE TRAILING VEHICLE. SLOWED AND PULLED OVER. INSPECTED ENGINE AND FOUND LARGE OIL LEAK. NO CHECK ENGINE OR LOW OIL LIGHTS ILLUMINATED PRIOR TO SMOKE. ENTIRE BOTTOM OF THE CAR COATED WITH OIL, INCLUDING EXHAUST SYSTEM, FRONT PASSENGER TIRE AND REAR TIRES. NO OIL REGISTERED ON DIPSTICK. TOWED TO TOYOTA DEALER WHERE THE CAR WAS PURCHASED. FAILED PART WAS THE OIL COOLER HOSE. TECHNICIAN SHOWED ME THE FAULTY RUBBER HOSE WHICH HAD A PIN-HOLE LEAK AND THERE WAS BARELY ONE HALF QUART IN THE ENGINE, WHICH HOLDS 6.4 QUARTS. JUDGING BY HOW OFTEN I HAD BEEN LOOKING IN THE REAR VIEW MIRROR DUE TO TRAFFIC, I'D ESTIMATE THE LEAK WAS ONLY A FEW MINUTES IN LENGTH AND THE ENGINE WOULD HAVE BEEN WITHOUT OIL AND AT HIGHWAY SPEED VERY SOON IF I HADN'T NOTICED. THIS IS NOT AN EXTRAORDINARY EVENT UNTIL YOU REALIZE THAT THE OIL HOSE THAT FAILED WAS PART OF TOYOTA'S 90K OIL COOLER HOSE LIMITED SERVICE CAMPAIGN FOR 2GR-FE V6 ENGINES IN 2011. I HAD MY CAR UNDERGO THIS FIX, WHICH SIMPLY REPLACED A RUBBER HOSE WITH ANOTHER RUBBER HOSE WHICH WAS SUPPOSEDLY MADE FROM A COMPOUND THAT BETTER RESISTS HOT OIL. THE REPLACEMENT HOSES ARE FAILING, WHICH IS WHAT TOYOTA TSB-0201-11 "OIL COOLER SEEP" (DEC 21, 2011) IS MEANT TO COVER AND IT REPLACES THE RUBBER OIL HOSES WITH AN ALL-STEEL HOSE. HOWEVER, IT ONLY APPLIES TO CUSTOMERS STILL UNDER THE 36,000 MILE WARRANTY AND WITH A "SEEPING" HOSE. MOST 2007 SIENNA OWNERS, LIKE ME, WERE WELL PAST WARRANTY MILEAGE IN 2011, HAD NO INDICATION FROM TOYOTA THAT THE RUBBER OIL HOSES WERE POTENTIAL PROBLEMS AND ARE ONLY GETTING THE STEEL HOSE AFTER CATASTROPHIC ENGINE OIL LOSS. I WAS BILLED $532 FOR THE OIL COOLER HOSE REPLACEMENT AND QUOTED $307 TO REPLACE THE O2 SENSOR WHICH WAS DAMAGED BY THE VOLUME OF HOT OIL THAT SPRAYED ON IT. HUGE OIL LOSS AT HIGHWAY SPEEDS. TOYOTA KNOWS, BUT MANY OWNERS DO NOT. *TR

TL* THE CONTACT OWNS A 2007 TOYOTA SIENNA. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 55 MPH, THE CHECK ENGINE WARNING LIGHT ILLUMINATED. THE CONTACT CHECKED THE OIL LEVEL AND NOTICED IT WAS LOW ON OIL. THE CONTACT ADDED OIL AND THE VEHICLE WOULD NOT RESTART. THE VEHICLE WAS TOWED TO A DEALER, WHO STATED THAT THE ENGINE NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 127,000.
