CERTAIN SPORT UTILITY VEHICLES HAVE A CHILD PROTECTION LOCK (CPL) SYSTEM ON BOTH OF THE REAR SIDE DOORS. WHEN AN OPERATOR OF THE VEHICLE CLOSES THE DOOR VERY HARD WITH THE CPL LEVER SET TO THE LOCK POSITION, THERE IS A POSSIBILITY THAT THE LEVER MAY CONTACT THE BODY PANEL, CAUSING THE CPL LEVER TO MOVE INTO THE UNLOCK POSITION.
THIS CONDITION COULD ALLOW THE DOOR TO BE OPENED WITH THE INSIDE WHILE THE OPERATOR BELIEVES THAT THE CPL WAS ACTIVATED. IF THE DOOR WERE OPENED FROM THE INSIDE WHILE THE VEHICLE WAS IN MOTION, AN OCCUPANT COULD FALL OUT AND BE INJURED.
DEALERS WILL SHORTEN THE CPL LEVER. OWNER NOTIFICATION BEGAN MAY 7, 2004. OWNERS SHOULD CONTACT TOYOTA AT 1-800-331-4331.

ON CERTAIN SPORT UTILITY VEHICLES EQUIPPED WITH FIVE FACTORY ALLOY WHEELS (MODEL 6934 AND 6936), WITH FACTORY LLAT, AND WITH PORT INSTALLED WR4, FOUR ALLOY WHEEL UPGRADE PROCESSED AT THE JACKSONVILLE, FLORIDA PORT AND DISTRIBUTED BY SOUTHEAST TOYOTA DISTRIBUTORS IN THE STATES OF ALABAMA, FLORIDA, GEORGIA, NORTH AND SOUTH CAROLINA, WHEN THE VEHICLES WERE PROCESSED AT THE PORT, AN ALLOY TIRE/WHEEL UPGRADE WAS INSTALLED. THE UPGRADE INCLUDED 4 ALLOY WHEELS. THE ORIGINAL SPARE TIRE/ALLOY WHEEL WAS NOT CHANGED. THE SPARE TIRE REQUIRES THE USE OF A DIFFERENT STYLE OF WHEEL NUT TO ATTACH IT TO THE VEHICLE.
IF THE SPARE TIRE/WHEEL IS INSTALLED ON THE VEHICLE USING THE WHEEL NUTS PROVIDED FOR THE UPGRADE ALLOY WHEEL, DAMAGE TO THE WHEEL COULD RESULT AND COULD EVENTUALLY LEAD TO A LOOSE WHEEL.
OWNERS WILL BE PROVIDED WITH DIFFERENT STYLE LUG NUTS, A WARNING LABEL FOR THE SPARE RE/ALLOY WHEEL, AND AN OWNER'S MANUAL ADDENDUM.

Engine and engine cooling, Jan 15, 2011
CAR TEMP GAGE WENT UP PAST H AND THERE WAS NO HEAT IN CAR. I STOPPED AS SOON AS POSSIBLE AT A MALL PARKING LOT AND CALLED SERVICE. HAD CAR TOWED TO GARAGE. PER OWNER OF GARAGE, THE HEAD GASKET LEAKED DUE TO BOLTS STRIPPING IN THE ENGINE. HE THEN FIXED THE PROBLEM AND THEN UPON TEST DRIVE THE TENSIONER FAILED AND CHAIN JUMPED CAUSING FURTHER REPAIRS TO NOT BE COST EFFECTIVE. THROUGH RESEARCH HE INFORMED ME THAT THIS IS A WELL DOCUMENTED PROBLEM WITH THE 2003 HIGHLANDER ENGINES AND THAT TOYOTA IS NOT BACKING THE PROBLEM. I CALLED TOYOTA AND SINCE RECALL HAS NOT BEEN ISSUED THEY STATED THEY CANNOT HELP ME. I FEEL THE HIGHLANDER SHOULD HAVE LASTED MORE THAN 8 YEARS AS I HAD KEPT UP WITH REQUIRED MAINTENANCE.

TL*THE CONTACT OWNS A 2003 TOYOTA HIGHLANDER. WHILE DRIVING APPROXIMATELY 55 MPH THE CHECK ENGINE, ASC, AND TRACTION CONTROL LIGHTS BEGAN ILLUMINATING ON THE DASHBOARD. THE VEHICLE BEGAN TO LOSE CONTROL AND THE WHEELS WOULD SPIN UNCONTROLLABLY WHILE ACCELERATING. THE VEHICLE WAS TAKEN TO AN INDEPENDENT REPAIR SHOP WHERE THEY WERE UNABLE TO DIAGNOSE THE FAILURE BECAUSE THE CHECK ENGINE LIGHT WAS NO LONGER ILLUMINATED. THE FAILURE RECURRED AND THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER WHERE THE CONTACT WAS TOLD THAT THE OXYGEN SENSORS FAILED. THE OXYGEN SENSORS WERE REPLACED. THE FAILURE CONTINUED TO RECUR INTERMITTENTLY. AFTER EACH FAILURE THE OXYGEN SENSORS WERE REPLACED AGAIN. THE FAILURE MILEAGE WAS 40,000 AND THE CURRENT MILEAGE WAS 55,000.

MY 2003 TOYOTA HIGHLANDER'S TEMP GAUGE STARTED GOING TOWARD THE H WHILE DRIVING ABOUT 30 MPH. I TURNED THE HEAT ON IN THE CAR AND THAT MADE THE GAUGE GO BACK DOWN TO NORMAL. I TOOK THE CAR TO A TOYOTA DEALERSHIP WHERE I WAS TOLD MY HEAD GASKET WAS BLOWN AND I NEEDED A NEW ENGINE FOR ABOUT $8000! I TOOK THE CAR TO AN INDEPENDENT MECHANIC THAT TOLD ME THE ENGINE ITSELF WAS FINE BUT 3 BOLTS ON THE HEAD GASKET WERE STRIPPED. THE REPAIR IS COSTING AN APPROXIMATE $2500 TO RETAP THE HOLES AND USE DIFFERENT BOLTS. I HAD DONE SOME RESEARCH AND I FOUND OUT THAT THIS IS A KNOWN PROBLEM WITH THE 2003 HIGHLANDERS AND TOYOTA IS NOT DOING ANYTHING ABOUT IT (I HAVE THE WEBSITE INFO AND COMPLAINTS IF NEEDED). MANY PEOPLE WHO HAVE PURCHASED THIS YEAR/MAKE/MODEL HAVE SPENT THOUSANDS OF DOLLARS REPAIRING THIS DEFECT THAT TOYOTA KNOWS ABOUT BUT WILL NOT TAKE CARE OF. I CALLED TOYOTA NATIONAL CUSTOMER SERVICE AND THEY GAVE ME THIS WEBSITE INFORMATION TO FILE A COMPLAINT (I HAVE A CLAIM NUMBER IF YOU NEED IT). I AM VERY UPSET, ACTUALLY OUTRAGED, THAT HERE WE ARE AGAIN FINDING OUT THAT TOYOTA HAS MORE ISSUES WITH THEIR VEHICLES AND WON'T DO ANYTHING ABOUT IT. I BOUGHT THIS CAR BECAUSE I THOUGHT TOYOTAS WERE RELIABLE. PLEASE DO SOMETHING ABOUT THIS AND HELP ALL OF US WHO BOUGHT THE 2003 HIGHLANDERS RECOVER THE MONEY WE HAVE SPENT ON REPAIRS TO AN OBVIOUS MANUFACTURER'S DEFECTIVE PART USAGE. THANK YOU! *TR

TL*THE CONTACT OWNS A 2003 TOYOTA HIGHLANDER. WHILE DRIVING APPROXIMATELY 65 MPH WITH THE AIR CONDITIONER ON SHE NOTICED HOT AIR BEGAN TO FLOW FROM THE VENTS. SHE ALSO NOTICED THAT THE TEMPERATURE GAUGE MALFUNCTIONED. THE VEHICLE WAS DRIVEN ONTO THE EMERGENCY LANE AND SHUT OFF WHILE SHE ADDED COOLANT TO THE ENGINE. THE VEHICLE WAS THEN TAKEN TO AN AUTHORIZED DEALER WHERE SHE WAS INFORMED THAT THERE WAS AN ENGINE LEAK AND SOME OF THE BOLTS WERE LOOSE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 109,171. THE CURRENT MILEAGE WAS 110,000.
Engine and engine cooling, Nov 3, 2010
2003 TOYOTA HIGHLANDER WITH 110,000 MILES STARTED TO OVERHEAT AND LOSE COOLANT. TOOK IT TO DEALERSHIP AND LEARNED THAT THE CYLINDER HEAD BOLTS HAD COME LOOSE DUE TO THE HOLES IN THE BLOCK BEING STRIPPED. TOYOTA ESTIMATED $3000 TO TAKE THE BLOCK OUT TO A MACHINIST TO BORE NEW HOLES, BUT IF THAT DIDN'T WORK IT WOULD COST $6000 TO REPLACE THE BLOCK. I THEN TOOK THE CAR TO A PRIVATE MECHANIC WHO SAID IT WOULD COST $9600 TO TAKE OUT THE BLOCK AND SEND TO MACHINIST OR BUY A RE-MANUFACTURED ENGINE FOR $8200. THE PRIVATE MECHANIC STATED THIS PROBLEM IS DUE TO FAULTY MANUFACTURING OF THE ENGINE AND ALSO STATED THAT HE SEES THIS PROBLEM ALL THE TIME IN THESE TYPES OF VEHICLES. ON THE INTERNET I HAVE FOUND CONSUMERS SHARING THE SAME STORIES ABOUT SIMILAR VEHICLES BY TOYOTA WITH SIMILAR ENGINES THAT HAVE THE SAME PROBLEM; SOME ONLY LASTING 70,000 MILES. I PUT IN A CALL WITH TOYOTA HEADQUARTERS AND THEY GAVE ME A REFERENCE NUMBER IN CASE ANY RECALLS SHOULD ARISE. TOYOTA SAID THAT THERE WAS NOTHING THEY COULD DO OUT OF "GOOD FAITH" SINCE IT IS PASSED THE WARRANTY MILEAGE AND SINCE I DID NOT DO ALL MY SERVICING AT TOYOTA. I CHANGED THE OIL EVERY 3,000 MILES AND TOOK VERY GOOD CARE OF THIS VEHICLE AS IT WAS MY FIRST PURCHASE OF A NEW VEHICLE AND I THOUGHT IT WOULD LAST ME A LONG TIME. *TR

2003 TOYOTA HIGHLANDER 2.4L 4-CYLINDER ENGINE, 108,000 MILES, DEVELOPED COOLANT LEAK ON THE BACK SIDE OF THE TOP OF THE ENGINE, ADJACENT TO AN INSULATOR PAD AT THE BACK OF THE ENGINE BLOCK. THE BACK 3 HEAD BOLTS WERE STRIPPED, ALLOWING COOLANT TO ALSO LEAK INTO THE ENGINE. THE TOYOTA DEALER SAYS THAT THE SHORT BLOCK OR ENTIRE ENGINE MUST BE REPLACED, WITH NO OTHER OPTION. THE HEAD HAD NEVER BEEN OFF SINCE ORIGINAL FACTORY MANUFACTURE/ASSEMBLY. BASED ON THE FREQUENCY OF IDENTICAL ENGINE FAILURES, FAULTY ASSEMBLY AND/OR DESIGN ASSURES EVENTUAL FAILURE OF THE ENGINE. *TR

2003 TOYOTA HIGHLANDER HAS HEAD BOLTS STRIPPED FROM BLOCK, CAUSING FLUID TO SLOWLY LEAK FROM ENGINE AND OVERHEAT. FIRST SYMPTOM IS AC BLOWS HOT AIR. MOST FOLKS WHO EXPERIENCE THIS BURN UP THE ENGINE, BUT I WAS FORTUNATE AND WAS ABLE TO HAVE IT REPAIRED AT A COST OF $2750.00 !!!!! THIS IS A CLEAR DEFECT, HEAD BOLTS DO NOT SIMPLY GET STRIPPED FROM A BLOCK. *TR

VSC (VEHICLE STABILITY CONTROL, INCLUDING ABS) & CHECK ENGINE LIGHTS HAVE BEEN TURNING ON INTERMITTENTLY ALMOST FROM THE START OF OUR OWNERSHIP OF THIS 2003 TOYOTA HIGHLANDER V6 AWD LIMITED AND AFTER COSTLY REPAIRS AT THE DEALER THEY ARE STILL ON CONTINUOUSLY. LAST TIME (MAY-JUNE 2010) DEALER REPLACED FRONT BRAKE PADS & ROTORS; REAR AXLES AND SPEED SENSORS AND NOW WANTS TO REPLACE ADDITIONAL COMPONENTS THAT DO NOT APPEAR CONNECTED. FIRST TIME CAR WAS SERVICED UNDER WARRANTY AT DEALER AND THAT TOO DID NOT LAST FOR LONG. TOYOTA CAR SATISFACTION CENTER HAS NOT BEEN HELPFULL. CASE # [XXX]. FORD HAS ISSUED A RECALL FOR SIMILAR ISSUE RECENTLY: 10S13 FOR REAR AXLE BREAKAGE IN THE SNOW BELT! TOYOTA REFUSES TO ACKNOWLEDGE ISSUE AND INTERNET HAS MANY DISCUSSIONS ON TOPIC.

2003 4 CYLINDER TOYOTA HIGHLANDER. COOLANT LEAK AND SUBSEQUENT NEED FOR A NEW REPLACEMENT ENGINE DUE TO THE DEFECT OF 3 REAR ENGINE SHORT BLOCK SCREWS/THREADS. HAD LESS THAN 85K MILES ON VEHICLE, WHEN FOUND A COOLANT LEAK UNDERNEATH ENGINE BLOCK OF VEHICLE IN GARAGE AFTER HAVING NO ISSUES PRIOR WITH ENGINE, RADIATOR OR ANY ASSOCIATED ACCESSORIES TO THE COOLANT SYSTEM/ENGINE SYSTEM OF VEHICLE. TOOK TO A TOYOTA DEALER PRIOR TO ANY OVERHEATING OR VEHICLE OPERATION FAILURES OR RADIATOR FAILURE. TOYOTA DEALER PULLED ENGINE MANIFOLD AND COVER OFF TO INVESTIGATE AND FOUND THAT WHEN THEY PULLED THE THREE SCREWS THAT CONNECT THE ENGINE COVER THAT COVER THE HEADS/CYLINDERS, THE THREADS ASSOCIATED WITH THE SCREWS CAME WITH THEM. THE ONLY FIX PER DEALERSHIP DETERMINED TO BE A BRAND NEW SHORT ENGINE BLOCK AND ACCESSORY REPLACEMENT FOR $6,470. DATE ON THIS IS AUGUST/2010. HAVE ALL PAST SERVICE HISTORY OIL CHANGES/TRANSMISSION CHANGES, RADIATOR CHANGES, WATER PUMP SERVICE, ETC FROM 0 MILES TO CURRENT. TOLD THAT THE SCREWS WERE NEVER SPRAYED AND SEALED CORRECTLY, THUS CORRODED INTO THE THREADS AND CAUSED FAILURE WITH BOTH ITEMS. VERY UNHAPPY THAT AN ENGINE IS GOING TO BE PAID FOR AND REPLACED BY CONSUMER ON AN OBVIOUS MANUFACTURER ERROR. MORE AND MORE OF THESE SPECIFIC ISSUES WILL ARISE WITH TIME ON THESE 4 CYLINDER EARLY 2000 TOYOTA HIGHLANDERS. THEY WILL NEED TO RELIEVE THE CONSUMER OF A FULL PAYMENT OF A NEW ENGINE OR BURDEN THEMSELVES ON LOSING EVEN MORE LOYAL TOYOTA CONSUMERS. ----TOYOTA ONLY CONSUMER SINCE 1994.....TILL NOW!!!! *TR

I HAVE A 2003 TOYOTA HIGHLANDER WITH ONLY 97,000 MILES THAT KEEPS "OVER HEATING". I HAVE REPLACED EVERYTHING UNDER THE HOOD EXCEPT THE ENGINE. THIS PROBLEM STARTED AROUND NOV. 2009. I HAVE READ OTHER BLOGS THAT HAVE THE SAME COMPLAINT AND IT APPEARS TO BE THE "BOLTS ON THE ENGINE ARE STRIPPED/DEFECTED" AND ALLOWS THE COOLANT TO LEAK OUT CAUSING OVERHEATING. ONE BLOG I READ STATED HE HAD THE "BLOTS" REPLACED AND THE NEW BOLTS ARE EXPANDING AND DOING THE SAME THING (OVER HEATING) AGAIN! I HAVE CALLED SEVERAL DEALERS AND SO FAR NO RECALL FROM TOYOTA TO FIX THIS PROBLEM, ALTHOUGH ONE DEALER SAID THERE IS A MEMO FROM TOYOTA REGARDING THIS PROBLEM, BUT NO RECALL! PLEASE HELP, I AM A SENIOR ON A FIX INCOME AND CAN NOT AFFORD THE COST OF A NEW ENGINE. I HOPE YOU CAN HELP ALL OF US WITH THIS PROBLEM.....THANK YOU. *TR

MY WIFE'S TRUCK BEGAN LEAKING COOLANT. I WAS TOLD THE HEAD GASKET WAS BLOWN. I PAID NEARLY $1600 FOR THE REPAIRS. A YEAR LATER, THE COOLANT IS LEAKING. WHEN THE HEAD WAS PULLED, THE THREAD STRIPPED OUT ON 3 BOLTS. I FOUND THE SAME COMPLAINT NUMEROUS TIMES ON THIS WEBSITE AND ON OTHERS. AT THIS POINT, THE OPTIONS ARE THREAD INSERTS THAT MAY WORK OR A NEW ENGINE! AT THIS POINT, I HAVE BEEN ATTEMPTING TO GET HELP FROM TOYOTA. THERE HAS BEEN NOTHING TO DATE. *TR

Engine and engine cooling, Apr 1, 2010
MY 2003 HIGHLANDER HEAT GAGE INDICATED THE ENGINE WAS STARTING TO GET HOT. I PULL INTO SERVICE STATION TO CHECK COOLANT LEVEL AND NOTICED COOLANT LEAKING ON THE GROUND. I WAITED FOR ABOUT 15 MINUTES TO ASSURE MYSELF IT WAS SAFE TO TAKE OFF THE RADIATOR CAP. I COULD NOT SEE ANY COOLANT SO, I PURCHASED A GALLON OF PRE-MIXED COOLANT AND POURED IN ABOUT 1/2 TO 3/4 GALLON TO BRING IT UP TO FULL. I MADE THE TRIP HOME WITHOUT THE CAR GETTING HOT, BUT NOTICED THE LEAK WAS STILL THERE. I HAD THE VEHICLE LOOKED AT BY A LOCAL TOYOTA DEALER AND WAS TOLD THE CAR NEEDED MAJOR REPAIRS. THERE IS A TECHNICAL SUPPORT BULLITIN ON THE ENGINE IN QUESTION. A 2.4 LITRE (4 CYLINDER) ENGINE COMMON ON CAMARYS AND HIGHLANDERS. I FEEL TOYOTA SHOULD HAVE TO REPAIR THIS VEHICLE IN LIGHT OF THE FACT TOYOTA HAS KNOWN OF THE DESIGN DEFECT ON OTHER MODELS (CAMARY AND HIGHLANDERS). WHEN I TOOK THE CAR IN FOR REPAIRS THE SERVICE SCHEDULER KNEW EXACTLY WHAT PROBLEM I WAS DESCRIBING TO HIM ABOUT MY CAR. THIS INDICATED TO ME, TOYOTA HAS INFORMED THEIR DEALERS OF THE PROBLEM OR, THEY WOULDN'T HAVE SENT A SERVICE BULLITIN ON THE VERY FIX TO MY CARS PROBLEM. THE SERVICE BULLITIN DESCRIBED (3) HEAD BOLTS AROUND THE INTAKE MANIFOLD WOULD STRETCH AND FAIL TO SEAL THE HEAD THUS, LEAK COOLANT. THE BULLITIN EVEN DESCRIBES INSTALLING HELI-COILS IN THE (3) AFFECTED BOLTS TO SOLVE THE PROBLEM. THIS APPEARS TO BE ANOTHER FAILURE OF TOYOTA TAKING RESPONSIBILITY FOR KNOWN DEFECTS IN THEIR AUTOMOBILES. I BOUGHT AND PAID FOR THIS VEHICLE IN GOOD FAITH ON THE RELIABILITY RECORD OF THE TOYOTA COMPANY'S PAST RECORD. I NOW FEEL I HAVE BEEN TREATED UNFAIRLY BY THIS COMPANY. I WOULD UNDERSTAND IF THIS WAS AN ISOLATED OCCURANCE, BUT IT IS NOT AND TOYOTA KNOWS THIS FULL WELL. SERVICE BULLITINS DON'T GET SENT TO ALL DEALERS FOR A SINGLE OCCURANCE. PLEASE HELP !

VEHICLE SUDDENLY LEAKS ENGINE COOLANT TO THE OUTSIDE OF VEHICLE WITHOUT ANY WARNING OF OVERHEATING. LEAK IS COMING FROM A DEFECTIVE HEAD BOLT AND CANNOT BE FIXED.

A VERY COMMON ISSUE AMONG 4 CYLINDER 2001-2006 TOYOTA ENGINES IN THE CAMRY,HIGHLANDER AND RAV 4 LEAKING HARMFUL COOLANT TO THE OUTSIDE OF VEHICLES THAT IS DEADLY TO HUMANS AND ANIMALS IF CONSUMED.

FAULTY ELECTRONIC COMPUTER MODULE ON 2003 TOYOTA HIGHLANDER THROWS MULTIPLE ERROR CODES TO INDICATE A NUMBER OF PROBLEMS WITH EMISSION COMPONENTS. ERROR CODES CALL OUT OXYGEN SENSORS, (THERE IS FOUR SENSORS ON 2003 (4) CYLINDER HIGHLANDERS). FIX ONE SENSOR AND ANOTHER POPS UP BAD ACCORDING TO THE ERROR CODES. ANOTHER $400 REPAIR BILL ! TOYOTA WILL REPLACE THE MODULE ON CARS WITH WARRANTY, NO PROBLEM. HOWEVER, THEY DENY THERE IS ANY PROBLEMS WITH THE MODULE WHEN NO WARRANTY IS INVOLVED. CODES AT TIMES ALSO SHOW A FAULTY CATALYTIC CONVERTER ($1000 REPAIR BILL ). IF YOU VISIT THE TOYOTA NATION WEB SITE YOU WILL SEE MANY REPORTS OF THE COMPONENT AT ISSUE. THIS IS ON THE SAME VEHICLES AS THE ONE I OWN. SOME PEOPLE HAVE REPORTED TOYOTA CHARGES UNSUSPECTING CUSTOMERS $1600 TO REPAIR THESE FOUR SENSORS. ( NOT MY WORDS, TAKEN OFF THE TOYOTA NATION FORUMS). PLEASE DEMAND TOYOTA REPLACE THE MODULES ON THESE VEHICLES. THANK YOU ! *TR

THIS PERTAINS TO MY WIFE'S 2003 TOYOTA HIGHLANDER SUV, 4 CYLINDER ENGINE. ON FRIDAY, AUGUST 28, 2009, WHILE DRIVING SHE NOTICED THE TEMPERATURE GAGE ON THE DASHBOARD WAS HIGH. SHE DROVE THE CAR HOME AND CHECKED THE COOLANT LEVEL. IT WAS EXTREMELY LOW. SHE REFILLED THE COOLANT AND DIDN'T DRIVE THE SUV UNTIL SHE WENT TO HER APPOINTMENT ON WEDNESDAY, SEPTEMBER 9, 2009 WITH THE HAWAII TOYOTA DEALER SERVCO'S MOTOR IMPORTS SERVICE & PARTS CENTER AT 609 SOUTH STREET, HONOLULU, HAWAII 96813. THEY TOLD HER THE ENGINE HAD A BLOWN HEAD GASKET. WE UNDERSTAND THIS IS BECAUSE THE CYLINDER HEAD BOLTS ARE STRIPPED ON THE BACK SIDE OF THE ENGINE. THIS IS WHAT CAUSED THE COOLANT LEAK IN THE FIRST PLACE. SERVCO TOLD US THAT THE SURE REPAIR (A WHOLE NEW ENGINE) WOULD EXCEED $20,000, AND THE LESS SURE REPAIR (TRYING TO FIX THE OLD ENGINE) WOULD COST $13,000. WE PICKED UP THE CAR THE NEXT DAY AND TOOK IT TO PRIAM'S AUTOMOTIVE SERVICE & REPAIR AT 2002 PAUOA ROAD. THEY DID A QUICK TEST AND SAID THAT THE HEAD GASKET WAS INDEED BLOWN, AND REFERRED US TO ROD'S AUTO SERVICE AT 972 KAWAIAHAO STREET BECAUSE PRIAM'S WAS NOT EQUIPPED TO HANDLE THAT MAGNITUDE OF REPAIR. ROD'S HAS ADVISED US THAT THE BEST SOLUTION IS REPLACING THE ENTIRE ENGINE WITH A REBUILT ENGINE FOR $5,000, BUT THIS HAS BECOME A COMMON PROBLEM WITH TOYOTA HIGHLANDERS AND LOCATING A REBUILT ENGINE ON THE MAINLAND WILL TAKE TIME. IN DOING SOME INTERNET RESEARCH, I'VE LEARNED THAT CAMRYS OF THE SAME VINTAGE HAVE ALSO DEVELOPED SIMILAR PROBLEMS, BUT IT LOOKS LIKE TOYOTA IS REFUSING TO RECALL THE VEHICLES AND FIX THE DESIGN FLAW. HTTP://WWW.CAMRYFORUMS.COM/FORUM/SHOWTHREAD.PHP?P=21539 TO DATE, THE VEHICLE REMAINS IN DISREPAIR. *TR
