TL* THE CONTACT OWNS A 2003 TOYOTA HIGHLANDER. WHILE DRIVING 45 MPH THE ACCELERATOR PEDAL BECAME STUCK. HE DOWN-SHIFTED , THEN SHIFTED THE VEHICLE INTO NEUTRAL, AND THEN APPLIED THE BRAKES. HE WAS ABLE TO STOP THE VEHICLE. DURING THE FAILURE, THE FLOOR MAT WAS NOT UNDER THE PEDAL. THE VEHICLE WAS TAKEN TO THE DEALER FOR INSPECTION. THE TECHNICIAN STATED THAT THE THROTTLE WAS OPEN, WHICH COULD AFFECT THE SPEED. HOWEVER THE DEALER COULD NOT DUPLICATE THE PROBLEM OR LOCATE ANY DIAGNOSTIC ERROR CODES.. THE FAILURE MILEAGE WAS 82,467.

THROTTLE STUCK OPEN AND CONTINUED TO ACCELERATE ON MY 2003 TOYOTA HIGHLANDER LIMITED WHILE DRIVING NORTH ON RT 4 IN CALVERT COUNTY, MD. IT WAS NECESSARY TO WEAVE IN AND OUT OF TRAFFIC UNTIL I COULD SAFELY GET OFF ROAD. HAD VEHICLE TOWED TO NEAREST GARAGE. MECHANIC BLAMED THROTTLE BODY ASSEMBLY AND CLEANED. DROVE VEHICLE HOME WITHOUT INCIDENT. THROTTLE AGAIN STUCK OPEN NEXT TIME I STARTED VEHICLE AND BEGAN TO DRIVE AWAY FROM HOUSE. I HAD THE TOWED VEHICLE TO BAYSIDE TOYOTA, PRINCE FREDERICK, MD WITH THROTTLE STILL STUCK OPEN FOR THEM TO SEE WHAT WAS OCCURRING. SERVICE MANAGER SAID IT WAS NECESSARY TO REPLACE THROTTLE BODY ASSEMBLY WHICH WAS BAD. REPLACED TO THE TUNE OF $1,668.74. SERVICE MANAGER, WHO SUGGESTED MY FLOOR MAT MAY HAVE PUSHED DOWN THROTTLE BEFORE TOW TRUCK ARRIVED, SAID I WAS LUCKY TO GET THE CAR TO THE GARAGE SINCE THE WORN THROTTLE BODY ASSEMBLY MADE DRIVING DANGEROUS. I SENT A LETTER TO TOYOTA MOTOR SALES USA, INC, TORRANCE, CA ON 07/10/2009, AND EXPLAINED THE INCIDENT, THE POSSIBLE DANGEROUS RESULTS, AND THE HIGH COST OF REPAIR. TOYOTA RESPONDED WITH AN ACKNOWLEDGMENT DATED 07/25/2009, AND SAID I COULD CALL THEIR OFFICE IF INTERESTED IN DISCUSSING INCIDENT. I CALLED AND THEIR REPRESENTATIVE SAID THEY HAD NO RECORD OF SIMILAR INCIDENTS, AND THE VEHICLE HAD TO MANY YEARS AND MILES FOR A WARRANTY CONSIDERATION OF A CREDIT ON THE NEW THROTTLE BODY ASSEMBLY. I DON'T KNOW IF THIS CONVERSATION RESULTED IN A RECORD BEING MADE SINCE I RECEIVED A DUPLICATE OF THE 07/25/2009 ACKNOWLEDGEMENT LETTER IN 09/2009. UNFORTUNATELY, I WAS UNAWARE OF THE THROTTLE BODY ASSEMBLY BEING A PROBLEM IN TOYOTA VEHICLES PRIOR TO THE REPAIR, AND I DID NOT REQUEST THE OLD PART BE RETURNED TO ME. I DO HAVE MY COPY OF CORRESPONDENCE TO TOYOTA AND THEIR ACKNOWLEDGMENT OF RECEIPT. *TR UPDATED 06/14/10. *JB

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

TOYOTA HIGHLANDER 2003 SUN VISOR SAFETY ISSUE. THE SUN VISOR OF MY VEHICLE HAS A SAFETY HAZARD. I HAD IT REPLACED FOR A NEW ONE, AND THE PROBLEM CAME BACK AGAIN. THE SUN VISOR ON THE DRIVER SIDE WITH HOMELINKED/LIGHTED ON IT. IT DOES NOT STAY UP AND IT BLOCKS MY VIEW WHEN I AM DRIVING. I NOTICED ON THE INTERNET THAT MANY PEOPLE HAD THE SAME ISSUES WITH THIS SUN VISOR. THE TOYOTA REFUSED TO REPLACE IT. *TR ANDY NGUYEN

I HAVE A 2003 AWD V6 LIMITED HIGHLANDER (HL) WITH 115,000 MILES. ABOUT 200 MILES AGO, THE TRANSMISSION STARTED SLIPPING DURING THE THIRD TO FOURTH GEAR SHIFT. HL GOES INTO NEUTRAL, THE REVS GO WAY UP, THEN IT SHIFTS WITH A CLUNK. I CAN MINIMIZE THE CLUNK FROM A STOP BY ACCELERATING TO 25 MPH, TAKING MY FOOT OFF THE GAS, LETTING THE REVS DROP DOWN TO 1200 RPM (AT WHICH POINT THE TRANS WILL SHIFT TO FOURTH GEAR), AND THEN STEPPING ON THE GAS. THERE ARE NO PROBLEMS IN FIRST, SECOND, THIRD OR FOURTH GEAR. THE CAR RUNS FINE IN FOURTH GEAR. IT IS ONLY A PROBLEM WITH THE THIRD GEAR TO FOURTH GEAR SHIFT. TRIED NOT USING OVERDRIVE, BUT PROBLEM PERSISTS. THIS IS MY FIRST PROBLEM WITH THE HL. I ALWAYS GET MY HL SERVICED AT TOYOTA DEALER AT 5000 MILES INTERVALS. DEALER SAYS THE TRANS NEEDS TO BE REPLACED. IN CALIFORNIA, THE PRICE IS OVER $4500 FOR THE "NEW" TRANS. DEALER WILL GIVE ME A 10% DISCOUNT ON PARTS AND LABOR. I ASKED THE SERVICE MANAGER IF THERE WAS A WAY TO REPROGRAM THE TRANSMISSION COMPUTER MODULE ON MY 2003 HIGHLANDER. HE CHECKED AND SAID THAT THERE WAS NO WAY TO RE-PROGRAM THE MODULE AND THERE WERE NO TECHNICAL SERVICE BULLETINS ON THIS PROBLEM. I REPLACED THE TRANSMISSION. THE TRANSMISSION WAS REPLACED WITH A "REBUILT TRANS" FROM TOYOTA. THE TRANSMISSION CASE IS A USED CASE, BUT ALL OF THE INTERNAL PARTS ARE NEW. I SENT AN E-MAIL TO THE LOCAL TOYOTA DEALER TO THANK THE SERVICE MANAGER FOR CUSTOMER SERVICE. I ALSO ASKED THEM TO FORWARD THE NOTE ABOUT THE TRANSMISSION PROBLEM TO THE REGIONAL TOYOTA SERVICE REPRESENTATIVE. OTHER HIGHLANDER OWNERS HAVE SIMILAR AUTOMATIC TRANSMISSION PROBLEMS. SEE HTTP://TOWNHALL-TALK.EDMUNDS.COM/DIRECT/VIEW/.F0AABC6 NEEDLESS TO SAY, I AM VERY DISAPPOINTED IN THE QUALITY OF THE TOYOTA TRANSMISSION, WHICH IS A MAJOR PART OF THE DRIVETRAIN, AND SHOULD LAST MORE THAN 100,000+ MILES. *TR

ON THE TOYOTA HIGHLANDER FROM AT LEAST 2002 THROUGH CURRENT MODELS THE DRIVER'S SIDE SUN VISOR FAILS TO STAY IN THE FORWARD DETENT POSITION. WHEN THE FAILURE OCCURS, THE VISOR FALLS TO THE VERTICAL POSITION, BLOCKING THE DRIVER'S VIEW OF THE ROAD UNEXPECTEDLY. THIS CAUSES CONFUSION AND DISTRACTION WHICH POTENTIALLY COULD CAUSE LOSS OF CONTROL OF THE VEHICLE WITH DAMAGE AND INJURY OR DEATH RESULTING. THIS HAS BEEN REPORTED TO TOYOTA BY ME AND ACCORDING TO GOOGLE SEARCHES BY NUMEROUS PERSONS. TOYOTA DENIES ANY PROBLEM EXISTS. *TR
