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.

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.

I NOTICED THAT THE ENGINE NOISE CHANGED. TOOK THE SUV TO THE DEALER TO CHECK IT OUT, DEALER STATED THAT THE NOISE WAS OK AND RETURNED THE VEHICLE TO ME. AFTER DRIVING THE VEHICLE LESS THAN 10 MILES RETURNED IT TO THE DEALER AND THE ENGINE WAS BLOWN. *TR

WHILE DRIVING ON THE HIGHWAY, MY ENGINE TEMP IN MY 4 CYL, 4WD 2003 HIGHLANDER SUDDENLY SPIKED HIGH. I HAD TO PULL OF THE ROAD. TOWED TO DEALER. DEALER SAID BOLTS ON SHORT BLOCK OF ENGINE WERE STRIPPED AND ALLOWED COOLANT TO LEAK OUT AND ENGINE OVERHEATED. I WAS AT 68,000 MILES, SO OVER THE WARRANTY PERIOD. I TOOK IT TO MY LOCAL DEALER AND THEY SAID I HAD A BAD WATER PUMP...I PAID TO HAVE THAT FIXED, BUT THE CAR STILL OVERHEATED. I TOOK IT BACK TO THE DEALER AND THEY THEN SAID IT WAS THE ENGINE ITSELF..THE SHORT BLOCK, SOMETHING ABOUT THE SCREWS WERE STRIPPED, THAT I HAD GOTTEN A BAD ENGINE WITH STRIPPED SCREWS. DEALERS SERVICE MANAGER TOLD ME THIS WAS A KNOWN ISSUE ON SOME 4CYL 2003 HIGHLANDER BUT COULDN'T HELP ME AS IT WAS OUT OF WARRANTY!!! THE SERVICE MANAGER CALLED ME BACK LATER AND SAID THAT TOYOTA WOULD HELP OUT...I ENDED UP PAYING A TOTAL OF ALMOST $1000 FOR THE REPLACEMENT SHORT BLOCK, WITH TOYOTA PAYING THE REST OF THE COST FOR THE SHORT BLOCK REPLACEMENT. THIS WAS ON TOP OF THE COST I PAID JUST A FEW DAYS PRIOR FOR A WATER PUMP THAT TURNED OUT TO NOT BE THE ISSUE. VERY FRUSTRATING...I HAVE ALL MY RECEIPTS FOR MAINTENANCE AND FOR THESE REPAIRS. *TR I AM FILLING OUT THIS COMPLAINT OVER A YEAR AFTER THE INCIDENT, BECAUSE I HAVE SEEN THE SAME THING IN THE COMPLAINTS AND WANTED TO ADD MINE. I DO HAVE ALL THE DOCUMENTATION FOR MY REPAIRS FOR THIS AND AM MORE THAN WILLING TO ANSWER ANY QUESTIONS, THANK YOU.

THE SUV WAS OUT OF COOLANT & WATER AND MY HUSBAND TAKE THE CAR TO THE DEALER TO CHECK THIS PROBLEM AND FOR REGULAR MAINTENANCE (THE CAR ONLY HAS RECEIVED SERVICE AT THE DEALER, EXCEPT FOR TIRES). THE DIAGNOSTIC WAS THAT THE SHOCK BLOCK HAS IT THREADS SEPARATED FROM THE SCREWS (OR BOLTS). THE ENGINE HAS TO BE REMOVED IN ORDER TO CHANGE THE SHOCK BLOCK. THE REPAIR HAS COST $4701.31, BECAUSE IT WAS ALSO RECOMMENDED TO CHANGE THE OIL PUMP. PREVIOUS TO THIS REPAIR, THE SUV WAS TAKEN TO THE DEALER BECAUSE THERE WAS A RECALL TO REPROGRAM ITS COMPUTER BECAUSE THE CHECK ENGINE LIGHT TURNED ON (THIS HAPPENED TWICE). WE HAVE A FULL RECORD IN THE DEALER OF ALL MAINTENANCE CHECKS AND REPAIRS THE SUV HAD. *TR

ENGINE HEAD BOLTS ON 2003 TOYOTA HIGHLANDER BECAME LOOSE; THREADS HAD WORN OFF ON 2 OR 3 BOLTS THAT HOLD THE TOP OF THE ENGINE TO THE MAIN ENGINE BLOCK. VEHICLE HAS BEEN WELL-MAINTAINED; 87,000 MILES. REPAIR REQUIRES NEW ENGINE BLOCK AT COST OF $6,400. APPEARS TO BE MANUFACTURING DEFECT - ENGINE BOLTS SHOULD NOT COME LOOSE. TOYOTA REFUSES TO PROVIDE ANY ASSISTANCE IN REPAIR. VEHICLE OVERHEATED AND WAS TOWED TO REPAIR SHOP. *TR

REPLACEMENT OF A CHARCOAL CANISTER ON A 2003 TOYOTA HIGHLANDER. NO ACCIDENTS OCCURRED AS A RESULT OF THE REPLACEMENT OF THIS PART; HOWEVER, I AM CONCERNED ABOUT THE NUMBER OF REPORTS OF HAVING TO REPLACE THIS VERY EXPENSIVE PART. ALSO IF THE PART IS A SAFETY HAZARD (MAY CAUSE AN ENGINE FIRE) IT SHOULD NOT BE AT THE EXPENSE OF THE OWNER. THE PART IS AN EMISSION CONTROL DEVICE THAT IS SURELY REQUIRED BY THE GOVERNMENT. THIS ACTION IS TAKEN BECAUSE I NOTICED, WHILE RESEARCHING CHARCOAL CANISTERS THAT TOYOTAS COME UP FREQUENTLY AS HAVING TO HAVE THIS TYPE REPAIR. AT THIS WRITING I AM UNABLE TO CONFIRM THE PART IS DEFECTIVE AS IT IS THE ORIGINAL PART THAT CAME WITH THE VEHICLE WHEN I PURCHASED IT BRAND NEW. THIS IS NOT A PRE-OWNED VEHICLE. *TR

A FEW MONTHS AFTER THE PURCHASE OF MY NEW 2003 TOYOTA HIGHLANDER, IT HAS DEVELOPED A PRONOUNCED "TICKING" SOUND WITHIN THE ENGINE. I AM CONCERNED THAT THIS COULD MEAN THAT A PROBLEM IS DEVELOPING, AND IT IS ALSO AN ANNOYING SOUND IN AN OTHERWISE QUIET VEHICLE. I AM GOING TO REPORT THIS TO TOYOTA VIA THEIR WEB SITE. THIS VEHICLE COST ME ALMOST $35K AND I DO NOT FEEL THAT THIS PROBLEM IS INSIGNIFICANT NOR SHOULD BE IGNORED BY THE DEALER. SHOULD I CHOOSE TO SELL THE VEHICLE, I WOULD SUSPECT THIS WILL SIGNIFICANTLY LOWER THE PRICE I COULD ASK AND MAY EVEN PREVENT ME FROM UNLOADING IT ALTOGETHER. *NM

MY 2003 HIGHLANDER LIMITED 6-CYL. 4WD VEHICLE HAS A LOUD AUDIBLE CLICKING NOISE (SOUNDS LIKE VALVE LIFTERS TICKING) EMINATING FROM THE ENGINE SINCE I PURCHASED THE VEHICLE NEW FROM PAGE TOYOTA IN JAN '2003. THE CLICKING NOISE IS ONLY PRESENT WHEN THE ENGINE IS RUNNING. THE CLICKING NOISE IS ALWAYS AUDIBLE BUT THE VOLUME DECREASES AS THE VEHICLE REACHES NORMAL OPERATING TEMPERATURE.THE CLICKING NOISE IS VERY LOUD WHEN THE VEHICLE IS COLD. THE CLICKING NOISE FREQUENCY INCREASES WITH INCREASING ENGINE RPM AND DECREASES WITH DECREASING ENGINE RPM. THE TOYOTA RED HOLMAN CUSTOMER SERVICE REPRESENTATIVE STATED THAT THE CLICKING NOISE IS NORMAL AND CAN NOT BE REDUCED OR ELIMINATED. *AK

TWO MONTHS AFTER BUYING MY NEW 2003 HIGHLANDER IT DEVELOPED A LOUD TICKING IN THE ENGINE. TOYOTA TOLD ME THAT THIS WAS COMMON AFTER 3000 MILES OR SO BUT THAT THERE WAS NOTHING WRONG WITH IT, NOR COULD IT BE FIXED. I THINK THIS SIGNIFICANTLY REDUCES THE VALUE OF THE VEHICLE SINCE I HAVE HAD PASSENGERS ASK ME WHAT WAS WRONG WITH MY CAR.*AK
