2007 TOYOTA SIENNA Engine Problems

As a result of the transmission cooler being a part of the radiator system, the transmission cooler ruptured while driving causing immediate loss of power and the engine to overheat. This malfunction also caused coolant and transmission oil to contaminate the engine compartment as well as the transmission. This is a major iengineering flaw and safety issue as I was on the interstate when it happened and was stranded on the side of the highway until help could be obtained.

The contact owns a 2007 Toyota Sienna. The contact stated while driving 40 MPH going up a curvy road, the ABS service warning light illuminated, and the vehicle lost motive power for several seconds before independently regaining motive power. The contact stated that the failure was intermittent. The contact took the vehicle to a local dealer to be diagnosed however, the mechanic was unable to retrieve a fault code. The manufacturer was not made aware of the failure. The failure mileage was approximately 160,000.

Mileage: 160,000

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.

SAME HOSE BUSTED AGAIN. LOOKED ON INTERNET SITES & FOUND SAME PROBLEM HAS OCCURRED TO MANY PEOPLE WITH SAME VAN YEAR. LONGTERM ONGOING PROBLEM. CALLED TEJAS TOYOTA IN HUMBLE, TX AND SVC MGR SAID TOYOTA OFFERED AN EXTENDED WARRANTY (KNEW THERE WAS A PROBLEM), BUT IT ENDED AT 100,000 MILES/10YRS (WE HAVE 120, 900) AND IS 2007 VAN. WE'VE ALREADY HAD IT TOWED AND FIXED TWICE. WE'RE RECOVERING FROM NEAR DEATH/COVID AFRAID TO DRIVE IT SINCE WE CAN'T TRUST IT. BASED ON INTERNET STORIES BY OTHERS WITH SAME PROBLEM, & SVC MGR AT TOYOTA OPINION, FEAR IS WARRANTED. OUR VAN WAS REPAIRED 2X W/ SAME TYPE OF INFERIOR HOSE PUT ON VAN WHEN BUILT BY A MECHANIC NOT AT TOYOTA. NONE OF US REALIZED INFERIOR PART WAS THE PROBLEM.NOW WE NEED TO REPAIR IT AGAIN WITH A "KIT" THAT TOYOTA SPECIFICALLY MADE BECAUSE THIS IS KNOWN PROBLEM AFTER WE SPENT MANY 100S OF $S REPAIRING IT USING SAME TYPE PART WHEN BUILT. WOULDN'T FIX IT WHEN I CALLED IN 2015. IT HAD TO BREAK 1ST PER TOYOTA WHEN I CHECKED ON IT IN 2015 WHEN GOT NOTICE.TOYOTA SHOULD REPAIR IT AT NO COST & REIMBURSE ME FOR THE EXPENSES I'VE ALREADY HAD. MY HUSBAND HAD COVID AND ALMOST DIED AND IT HAPPENED THE DAY AFTER HE WAS RELEASED FROM A MONTH LONG COVID HOSPITAL STAY AND AGAIN WHEN I WAS TAKING HIM TO THERAPY FOR COVID 3 WKS LATER.

AS I WAS DRIVING THE VAN, I NOTICED A SMELL LIKE BURNING RUBBER, ALTHOUGH ALL GAUGES WERE NORMAL AND NO CHECK ENGINE LIGHT WAS ON. SINCE I WAS CLOSE TO HOME, I PULLED INTO THE GARAGE AND NOTICED SMOKE COMING FROM UNDER THE HOOD AND A TRAIL OF OIL ON THE DRIVE WAY. WITHIN A FEW MINUTES, THERE WAS A LARGE PUDDLE OF OIL UNDER THE VEHICLE AS WELL. I HAD IT TOWED TO THE MECHANIC AND WAS TOLD THE OIL COOLER HOSE HAD BROKEN. THE MECHANIC SAID IF I HAD DRIVEN IT TO THE SHOP, I LIKELY WOULD HAVE RUINED THE ENGINE BECAUSE THE OIL LOSS WAS SO SIGNIFICANT (OUT OF 5 QUARTS, ONLY .25 WAS REMAINING). THE MECHANIC ALSO SAID THAT TOYOTA WAS AWARE OF THIS ISSUE BUT DID NOT ISSUE A RECALL, EVEN THOUGH THE REPLACEMENT HOSES ARE NOW STEEL AND NOT RUBBER. THIS IS A SAFETY ISSUE AS THE ENGINE COULD HAVE SEIZED UP WHILE RUNNING (DUE TO THE QUICK LOSS OF OIL) CAUSING POTENTIALLY SERIOUS ACCIDENT AND INJURY.

Mileage: 144,000

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.

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.

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.

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.

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.

ON 4/10/15, I TOOK THE VEHICLE TO MOTOR IMPORTS SERVICE CENTER FOR PREARRANGED WARRANTY SERVICE WORK ON THE VEHICLE. MOTOR IMPORTS DECLINED TO PERFORM THE WARRANTY WORK, ALLEGING THAT THE VEHICLE WAS "TOO DIRTY" TO PERFORM, EVEN THOUGH AT LEAST TWO OF THE RECALLS WOULD INVOLVE NO AREA OF THE INTERIOR. WITH RESPECT TO THE INTERIOR, THE SHIFT ASSEMBLY WAS ALLEGEDLY "BLOCKED" BY A NEWSPAPER ON THE CONSOLE, AS WELL AS PENS IN THE ASHTRAY AND CD'S IN THE CONSOLE, AND FOR THIS, THEY CLAIMED THEY COULD NOT PERFORM THE WORK. IN ADDITION TO THE ABOVE RECALLS, THEY WERE TO INSPECT THE DASHBOARD FOR A FOURTH RECALL INVOLVING PREMATURE DEGRADATION OF THE ASSEMBLY, WHICH THEY DECLINED TO PERFORM AS WELL. *TR

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

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.

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

I AM THE SECOND OWNER OF THE VEHICLE. I WAS DRIVING ON INTERSTATE 5 AT 65 MILES PER HOURS FROM SACRAMENTO TO LOS ANGELES. THE TIME WAS 1600 ON 13 APRIL 2014. I DID NOT NOTICE ANY CRACK OR NOISE FROM ROAD DEBRIS DAMAGE WHILE I AM DIVING. THE RED LOW OIL WARNING LIGHT ON THE DASHBOARD DID NOT TURN ON AT THE TIME WHEN THE INCIDENT HAPPENED. I WAS PULLED OVER A REST STOP TO USE RESTROOM; I ALSO WALK AROUND THE VEHICLE TO CONDUCT A VISUAL CHECK AND FLUID CHECK AT THE SAME TIME. I WAS DISCOVERED ENGINE OIL WAS ALL OVER THE ENGINE BAY, UNDERCARRIAGE AND THE BACK LIFT DOOR DURING THE VISUAL CHECK. WHEN I CHECKED THE ENGINE OIL, THE DIP STICK SHOWED NO ENGINE OIL.

PRIOR TO THE TRIP, I PURCHASED THE ALL METAL VVT-I HOSE FROM A LOCAL DEALERSHIP, AGAIN NO WARNING FROM THE DEALERSHIP. I USED A LOCAL REPAIR SHOP TO REPLACE THE VVT-I HOSE LOCATE AT THE PASSAGE SIDE OF THE ENGINE TO AN ALL METAL PIPE SINCE I HAVE KNOWLEDGE ON THE RUBBER VVT-I HOSE HAVE THE SAME RUPTURE ISSUE. HOWEVER, I HAVE NO KNOWLEDGE ON THE T-SB-0201-11 WHICH IS THE TOYOTA TECHNICAL SERVICE BULLETIN TITLE OIL COOLER PIPE SEEP. THERE IS RECALL REGARDING SHIFT LOCK SOLENOID AND SEVERE CORROSION OF THE SPARE TIRE CARRIER CABLE ON THE 2007 SIENNA, HOWEVER, THERE IS NO RECALL ON POSSIBLE RUPTURE ON VVT-I HOSE OR OIL COOLER HOSE. IF THE RECALL WAS ISSUED OR AT LEAST WARNED BY DEALERSHIP, I WILL FIX THE OIL COOLER HOSE AT THE DEALER OR A LOCAL REPAIR SHOP AND AVOID THE ENGINE DAMAGE WHICH LEADED TO ENGINE REPLACEMENT. *TT

IT COST ME $977.3 TO REPLACE THE RADIATOR AND FLUSH THE TRANSMISSION. MY MECHANIC SAID IF I WOULD HAVE CONTINUED DRIVING WITH THESE 2 FLUIDS MIXING I WOULD HAVE DAMAGED THE TRANSMISSION BEYOND REPAIR FOR A BILL OF $3,000. MORE IF THIS IS A COMMON PROBLEM ON THESE CARS PEOPLE SHOULD AT LEAST BE NOTIFIED WHAT TO WATCH FOR OR BETTER YET REPAIRED BY THE COMPANY. *TR

DRIVING ON THE FREEWAY @ 85MPH WHEN THE CHECK ENGINE LIGHT CAME ON. PROMPTLY, I PULLED THE TOYOTA MANUAL WHICH SAID COULD BE FAULTY GAS CAP AND MAY GO OFF WITH CONSECUTIVE DRIVES ONCE FIXED OR IF IT STAYS ON AFTER TO GO TO DEALER. THE CAR WAS RUNNING FINE SO I HEADED TO MY EXIT TO PULL OVER. SHORTLY, THEREAFTER A HORRIBLE DIESEL ENGINE GRINDING NOISE. I HAD JUST HAD MY TIRES ROTATED (REPLACED JUST ONE MONTH PRIOR) THAT WEEKEND AND THE OIL CHANGED THE WEEKEND BEFORE. AS I WAS ABOUT TO PULL OVER THE ENGINE OIL LIGHT FLASHED. WHEN I PULLED OVER I IMMEDIATELY CHECKED THE OIL STICK DRY WE HAD BEEN GIVEN THE RUN AROUND ABOUT THE PART BY MOSSY NISSAN THAT THE PART WAS ON BACKORDER AND WAS PART OF THE RECALL. THE VEHICLE WAS LATER TOWED TO TOYOTA OF POWAY AND FOR $500+ TO INSPECT AND REPLACE THIS HOSE(NOT PART OF RECALL) WANTED ANOTHER $3000 TO TEAR DOWN THE ENGINE AND THE ADDL CHARGES TO FIX I HAVE RELIGIOUSLY HAD MY OIL CHANGED AND HAVE ALWAYS HAD MY TOYOTA CERTIFIED MECHANIC WORK ON MY CAR. I CONTACTED TOYOTA CONSUMER SERVICE FOR ASSISTANCE IN FIXING THE PROBLEMS THEY INDICATED THEY WOULD NOT HELP SINCE THE HOSES WERE NOT PART OF THE RECALL. THE HOSES ARE 2 RUBBER HOSES THAT HAVE CLAMPS LEADING TO A TRIANGULAR METAL PIECE. THE HOLE WAS NOT IN A LOCATION THAT SOMETHING COULD HAVE PIERCED ACCORDING TO MY INDEPENDENT MECHANIC WHO TRIED TO GET THE PART FROM THE FIRST DEALER....WHICH LEADS TO THE FACT THAT THESE ARE FAULTY HOSES THAT DETERIORATED. TOYOTA HAS OFFERED A GOODWILL PAYMENT OF $750 TOWARDS A NEW OR USED CERTIFIED TOYOTA CAR. BUT THAT IS AT A 20% INTEREST RATE. IT IS MY HOPE THAT OTHERS WILL SEE THIS AND GET THIS FIXED BEFORE THEY END UP LIKE ME SINGLE MOM OF 4 WITHOUT A CAR WORKING 5 DAYS A WEEK 150 MILES FROM MY BABIES AND CAN'T EVEN GO HOME TO SEE THEM TILL THE WEEKEND. A BIG THANK YOU TOYOTA. I HAVE PAID $800 OUT OF POCKET. *TR
