2003 Toyota Highlander Transmission Problems

Your transmission may slip when you shift into reverse, and then suddenly surge forward with unexpected acceleration. This can make reverse driving unpredictable and potentially unsafe. The transmission may need to be inspected, serviced, or replaced to resolve the slipping and surging.

NOTICED WHITE SMOKE COMING OUT OF THE TAILPIPE IN JUNE. THEN I NOTICED REDDISH/PINK FLUID ACCUMULATING ON GARAGE FLOOR IN JULY. TOOK IT IN ASSUMING EITHER A COOLANT OR TRANSMISSION FLUID LEAK. TOYOTA TOLD ME I NEEDED A NEW ENGINE BECAUSE THE BACK HEADBOLTS WERE STRIPPED AND THE HEAD GASKET WAS BLOWN. ALL THIS WAS DETERMINED WITHOUT REMOVING VALVE COVER AND CAMS, BUT INSTEAD BECAUSE IT'S A KNOWN ISSUE. MANY OWNERS REPORT THE SAME THING ON MESSAGE BOARDS. *TR

I WAS BACKING MY CAR FROM ACROSS THE STREET. AFTER SHIFTING TO DRIVE, MY CAR JUMPED BACK IN REVERSED FULL SPEED CRASH IN TO MY GARAGE. I HAD MY FOOT ON THE BRAKE BUT WOULDN'T STOP TILL IT HIT MY GARAGE WALL. *TR

ON APRIL 15, 2013 WHILE PARKING MY 2003 TOYOTA HIGHLANDER ALL OF A SUDDEN MY CAR ACCELERATED WHILE SHIFTING FROM REVERSE TO DRIVE WHILE I WAS PARKING. SUDDENLY MY CAR TOOK OFF WITH THE ENGINE FULL SPEED TO RED LINE ON THE TACHOMETER IN A SPACE OF FOUR FEET IT JUMPED THE PARKING BLOCK AND SMASHED INTO THE CENTER BLOCK WALL WITH MY FOOT ON THE BRAKE. THE DAMAGE TO MY CAR WAS $2000.00. THIS WAS THE SECOND TIME THIS HAS HAPPENED. I CONSIDER MYSELF LUCKY, BECAUSE I COULD HAVE BEEN HURT AND OTHER PEOPLE. I AM SCARED NOW WHEN I DRIVE MY CAR. *TR

TL*THE CONTACT OWNS A 2003 TOYOTA HIGHLANDER. WHILE DRIVING APPROXIMATELY 25 MPH, THE CONTACT APPLIED TO BRAKES BUT THE VEHICLE BEGAN TO ACCELERATE. THE CONTACT TRIED SEVERAL WAYS TO STOP THE VEHICLE (SHIFTING INTO NEUTRAL, USING THE EMERGENCY BRAKE) BUT THE VEHICLE CONTINUED TO REV. THE TIRES ALSO WERE SPINNING. THE CONTACT SHIFTED INTO NEUTRAL AGAIN AND TURNED THE VEHICLE OFF WHICH STOPPED IT. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER WHO STATED THAT THE TRANSMISSION DROPPED AND THE EXTRA FLOOR MAT CAUSED THE FAILURE. THE VEHICLE HAD NOT BEEN REPAIRED. THE CURRENT AND FAILURE MILEAGES WERE 90,000. UPDATED 03/24/11*LJ THE CONSUMER STATED THE FLOOR MAT WAS NOWHERE NEAR THE GAS PEDAL. IT WAS SECURELY IN PLACE. UPDATED 11/16/11

I PULLED INTO A PARKING SPACE AT A SHOPPING CENTER NEAR MY HOME, THEN BACKED UP A FEW FEET IN ORDER TO STRAIGHTEN MY CAR. WHEN I PUT THE TRANSMISSION INTO DRIVE, THE CAR SUDDENLY SURGED FORWARD ENTIRELY ON ITS OWN, STRIKING THE CONCRETE BARRIER A FEW FEET IN FRONT OF MY CAR. I DID NOT ACCELERATE, THERE WERE NO FLOOR MATS ON THE DRIVER'S SIDE, AND THE FORCE THREW ME AGAINST THE STEERING WHEEL. A WITNESS RAN OVER TO SEE I WAS INJURED, BUT I WAS JUST BADLY FRIGHTENED. THE FRONT FENDER WAS DENTED, BUT ACTUALLY POPPED BACK OUT AS I WAS STANDING BESIDE MY CAR WITH THE WITNESS. I HAD PREVIOUSLY COMPLAINED ABOUT THE ENGINE ALTERNATELY SLOWING AND SURGING AS I DROVE, USUALLY ONLY AT SPEEDS UP TO 40MPH, TO MY LOCAL SERVICE DEPARTMENT. WHEN I CALLED MY SERVICE DEPARTMENT, THEY GAVE ME A TOLL FREE NUMBER WHERE I SPOKE TO A TOYOTA CASE MANAGER WHO ASSIGNED ME A CASE NUMBER AND TREATED ME VERY COLDLY AND WITH SUSPICION, ASKING PERSONAL QUESTIONS ABOUT MY HEALTH, INSURANCE COMPANY AND DRIVING RECORD. I SAID I WAS JUST CONCERNED THAT MY CAR HAD BEHAVED LIKE ONE I HAD JUST HEARD ABOUT ON THE LOCAL NEWS, AND I WANTED TO KNOW WHAT TO DO AND PREVENT OTHERS FROM EXPERIENCING WHAT HAD HAPPENED TO ME OR WORSE THE CASE MGR. SAID THEY WOULD CALL ME BACK. THEY NEVER CALLED BACK. THE FOLLOWING MONTH I TOOK MY CAR IN FOR SERVICE AND ASKED THEM TO CHECK THE ELECTRICAL SYSTEM. THEY SAID THEY FOUND NO PROBLEMS. *TR

2003 V6 AWD TOYOTA HIGHLANDER FRONT TO REAR DRIVE SHAFT FAILURE (PROPELLER SHAFT). *TR

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

GENTLEMEN: I AM WRITING YOU THIS E-MAIL BECAUSE THERE IS A PROBLEM WITH MY CAR THAT IS NOT ONLY IRRITATING, BUT IS POTENTIALLY DANGEROUS TO ALL WHO OWN A FULL TIME FOUR-WHEEL DRIVE TOYOTA HIGHLANDER. MY HIGHLANDER IS A 2003, AND ALTHOUGH WE WERE PROMISED FULL TIME FOUR-WHEEL DRIVE WHEN WE BOUGHT IT, WE FOUND OUT LATER TO OUR HORROR THAT IT IS NOT. WHEN DRIVING DOWN A PAVED HIGHWAY, ALL FOUR WHEELS ARE DRIVING. THIS IS A TIME WHEN FOUR-WHEEL DRIVE IS NOT NEEDED. HOWEVER, A FEW MONTHS AGO, WE DROVE OFF THE PAVEMENT INTO SAND ON A PICNIC TRIP, BUT DID NOT WORRY BECAUSE THE 'FULL TIME' FOUR-WHEEL DRIVE WOULD PULL US OUT. IT DID NOT! ONE OF THE FRONT WHEELS BEGAN TO SPIN IN THE SAND AND THE OTHER THREE IMMEDIATELY STOPPED DRIVING. WE WERE STUCK! THE PROBLEM IS THAT THE DIFFERENTIAL BETWEEN THE FRONT AND REAR WHEELS IS NOT ANTI-SLIP, BUT THE STANDARD DIFFERENTIAL THAT WILL STOP ALL WHEELS FROM DRIVING WHEN ONE LOOSES TRACTION. THIS IS HARDLY FULL-TIME FOUR-WHEEL DRIVE NO MATTER HOW YOU DEFINE IT. WE WERE SOLD A CAR WE PAID FOR BUT DID NOT GET, AND SOMETHING NEEDS TO BE DONE TO RECTIFY THIS SITUATION. WHO KNOWS HOW MANY CUSTOMERS HAVE BEEN BILKED BY TOYOTA WITH THIS CAR, AND WILL GET THEM INTO TROUBLE THINKING THEY HAD A CAR THAT WOULD PULL THEM OUT. I WOULD LIKE TO START A CLASS ACTION LAW SUIT TO GET OUR MONEY BACK OR GET A FREE CAR THAT IS INDEED THE FULL TIME FOUR WHEEL DRIVE WE PAID FOR AND DESERVE. *TR

2003 TOYOTA HIGHLANDER V-6 WITH 66450 MILES. DRIVING HOME GOING 40 TO 45 MPH, CAR TRANSMISSION STARTED TO SKIP, ENGINE WOULD SURGE THEN BUCK AND ENGINE WOULD HESITATE. DROVE ON TO DEALER FOR DIAGNOSIS. *TR

REAR MAIN SEAL LEAK, LARGE AMOUNT. *TR

AFTER ONLY 64,000 MILES, THE TRANSMISSION ON MY 2003 TOYOTA HIGHLANDER STARTED SKIPPING. WHEN I ACCELERATED, THE CAR WOULD JUMP/SKIP. THIS COULD HAVE EASILY CAUSED A WRECK. *TR

I HAVE A 2003 4RUNNER THAT HAS A HORRIBLE CLUNKING SOUND THAT HAPPENS AT RANDOM. THE TOYOTA DEALER HAS ATTEMPTED TO FIX IT 3 TIMES. IT WILL HAPPEN WHEN COMING TO A STOP OR STARTING FROM A STOP. IT'S VERY ANNOYING AND NOT VERY COMFORTING. IF THE DRIVESHAFT IS SLAMMING AND MAKING THIS NOISE, I CAN'T IMAGING ANYONE THINKING THAT IS VERY SAFE. THE THING COULD BREAK AT ANY MOMENT. WHO KNOWS WHAT DAMAGE THE SLAMMING DOES TO IT! TOYOTA NEEDS TO FIX THIS BEFORE SOME GETS HURT FROM IT. *TR

2003 TOYOTA HIGHLANDER, 4 CYL , AUTO TRANS. BETWEEN 25 AND 45 MPH, WHEN YOU APPLY THE BRAKE ON THE AUTO AND THEN PRESS THE GAS TO RESUME YOUR FORWARD TRAVEL, THERE IS A KICK (LIKE A LOOSENESS IN THE TRANSMISSION AND DRIVE SHAFT) FOLLOWED BY THE MOTOR REVVING AS IT SHOULD AND THE TRANSMISSION DOWN SHIFTING. I WENT TO THE DEALER WHO TOLD ME YES, THERE IS A LOOSENESS CAUSED BY THE FACT THAT THERE IS A LOT OF RUBBER CONNECTORS HOLDING THE DIFFERENTIAL AND DRIVE SHAFT ASSEMBLY TO THE VEHICLE FRAME. OVER TIME THEY HAD FATIGUED (31000 MILES). THE DEALER TOOK NO ACTION. I HAVE A REGISTERED A COMPLAINT WITH TOYOTA (200508090110). A FINAL END RESULT WOULD BE THE DIFFERENTIAL AND ATTACHED DRIVE SHAFT FALLING OFF THE AUTO WHILE IT IS IN MOTION CAUSING A SERIOUS INJURY OR FATAL CRASH. *NM

DT: THE CONTACT NOTICED WHILE STOPPING AT A RED LIGHT SHE REACHED OVER TO GET SOMETHING AND HIT THE GEAR SHIFT WITH HER HAND AND WITH HER FOOT ON THE BRAKE THE VEHICLE SHIFTED FROM DRIVE TO NEUTRAL WITHOUT PUSHING THE BUTTON ON THE GEAR SHIFT. HER CONCERN IS THAT IF THE CAR IS IN LOW DRIVE, SECOND GEAR OR NEUTRAL IT CAN BE SHIFTED, THIS DEFECT CAN CAUSE AN ACCIDENT. CONTACT CALLED TOYOTA, AND THEY SAID THIS WAS A SAFETY FEATURE WHICH WAS MEANT TO DO THAT. CONSUMER WAS NEVER TOLD BY DEALER THAT THIS WAS A FEATURE OF VEHICLE. SHE BELIEVED THAT THIS WAS VERY DANGEROUS AND WAS A SAFETY ISSUE.*AK CONSUMER STATES VEHICLE DOES NOT SHIFT INTO REVERSE WITHOUT PRESSING THE BUTTON. *SB

2003 TOYOTA LIMITED 4-RUNNER V8- AWDFRONT-END VIBRATION PROBLEM. I FIRST PRESENTED THE VIBRATION PROBLEM TO MY DEALER THE LAST WEEK OF AUGUST! THEY TRIED BALANCING THE WHEELS WITH NO IMPROVEMENT. THEY AGREED THE PROBLEM WAS THERE AND NOTIFIED CORPORATE. THEIR TECHNICAL STAFF HAD THEM REMOVE THE FRONT AXELS AND RETEST THE VIBRATION WHICH STARTED AT 22 MPH, WENT TO 32MPH 42, 55, AND 62MPH NOW DISAPPEARED! A WEEK LATER A TECHNICAL REPRESENTATIVE MET WITH ME AND MENTIONED THAT SEVERAL VEHICLES IN PHOENIX HAD THE SAME PROBLEM. HE SUGGESTED IT PROBABLY WOULD TAKE ABOUT TWO MONTHS TO GET A FIX. TWO MONTHS LATER I TALKED TO THE TECH. REP. AGAIN AND HE MENTIONED THAT THE ENGINEERING GROUP HAD DETERMINED THE PROBLEM TO BE INTERFERENCES IN THE SPIDER GEAR ASSEMBLY IN THE FRONT DIFFERENTIAL, THEY WERE TRYING TO CORRECT THE CONDITION WITH THRUST WASHER SHIMS AND OTHER THINGS. I HAVE PRESENTED MY CLAIM TO THE CUSTOMER SUPPORT GROUP. I HAVE CALLED THEM REGULARLY ONCE A MONTH AND HAVE HAD NO SUCCESS AT FINDING WHAT THEIR SCHEDULE IS FOR THE FIX,--ONLY TO SAY WE ARE WORKING ON IT AND YOUR DEALER WILL NOTIFY YOU. IVE SINCE HEARD FROM MY DEALER STAFF THAT THEY HAVE A NUMBER OF LEXUS GX470'S AS WELL AS 4-RUNNERS INVOLVED. IM BEGINNING TO FEEL THAT THEY HAVE SO MANY VEHICLES WITH DIFFERENTIAL ASSEMBLIES INVOLVED, THAT IT MAY REQUIRE SOME KIND OF MAJOR REDESIGN AND BUILD. IT MIGHT BE A LONG TIME BEFORE WE SEE A FIX! I HAUL A POP-UP TRAILER AND DOES IT MAGNIFY THE PROBLEM!*AK

CAR STALLS (GAS PEDAL DOES NOT RESPOND) WHEN TURNING INTO TRAFFIC. ALSO WHEN SLOWING TO A LOW SPEED AND THEN ACCELERATING. THIS HAS CAUSED US TO ALMOST BE HIT SEVERAL TIMES IN THE SIDE AND IN THE REAR. MOST OF THE TIME WHEN THIS HAPPENS THE CAR WITH TIRE MARKS LIGHT ON THE INSTRUMENT PANEL COMES ON AND FLASHES. THERE IS NO WAY TO PREDICT WHEN THIS SUDDEN LOSS OF THE ACCELERATOR WILL HAPPEN. IT IS VERY DANGEROUS. THIS HAPPENS AT LEAST ONCE ALMOST EVERY TIME WE DRIVE. ALSO SOMETIMES WHEN YOU START THE CAR AND BEGIN TO GO YOU HEAR DINGING SOUNDS AND FEEL AND HEAR BUMPS AND GRINDING NOISES. 2 LIGHTS COME ON IN THE INSTRUMENT PANEL WHEN THIS HAPPENS. 1 READS VSC TRAC AND THE OTHER READS TRAC OFF. IF YOU STOP AND RESTART THE ENGINE IT WILL EVENTUALLY STOP DOING IT. SOMETIMES THIS IS AFTER 1 RESTART AND SOMETIMES IT HAS TAKEN 5 AND 6. ON DAY IT WOULD NOT STOP NO MATTER HOW MANY TIMES YOU RESTARTED AND WE HAD TO DRIVE WITH LIGHTS ON. THIS HAS HAPPENED ABOUT 10 DIFFERENT TIMES.
