2005 Toyota Highlander Powertrain & Transmission Problems

TRANSAXLE VENT IS LEAKING TRANSMISSION FLUID ONTO EXHAUST, POTENTIAL OF CATASTRAPHIC TRANSMISSION FAILURE DUE TO TOTAL SUDDEN LOSS OF TRANSMISSION FLIUD. LEAK IS CAUSE BY A DEFECTIVE SEAL

MY HIGHLANDER HAS 120,000 MILES ON IT AND THE TRANSMISSION SUDDENLY GAVE OUT WHILE DRIVING ON THE HIGHWAY. IT STARTED BY DOWNSHIFTING SUDDENLY, MAKING IT DIFFICULT TO RETAIN CONTROL OF THE VEHICLE. THEN I LOST ALL FORWARD POWER AND HAD TO COAST TO A STOP ON THE SIDE OF THE INTERSTATE. I AM NOW STUCK PAYING A $3500+ REPAIR BILL DESPITE KEEPING UP ON REGULAR MAINTENANCE ACCORDING TO THE MANUFACTURERS MAINTENANCE GUIDE. AFTER TALKING WITH SEVERAL MECHANICS, I FOUND OUT THIS IS APPARENTLY A COMMON PROBLEM ON THE TRANSMISSIONS USED BY THE RAV4S AND HIGHLANDERS, BUT TOYOTA HAS ONLY ISSUED RECALLS FOR THE RAV4S? VERY DISAPPOINTING. *TR

BOUGHT THE CAR AND NOT EVEN A WEEK AFTER OWNING IT I HAD TRANSMISSION PROBLEMS, I TOOK IT BACK TO THE DEALER THEY REPLACED THE TRANS AND UPDATED THE COMPUTER. THE PROBLEM STILL PERSIST, THERE IS A HUGE HESITATION IN THE TRANSMISSION WHEN SLOWING TO AN ALMOST STOP AND RE ACCELERATING. THE RPM'S REV UP BUT THE CAR DOES NOT RESPOND SOMETIMES. THIS IS VERY DANGEROUS WHEN GOING THROUGH INTERSECTIONS OR MERGING INTO TRAFFIC. THERE ARE NUMEROUS COMPLAINTS FROM PEOPLE EXPERIENCING THE SAME PROBLEM. I HAVE A NEW TRANS IN MY CAR, FLUID LEVELS ARE PERFECT THE COMPUTER HAS BEEN UPDATED AND STILL HAVING HUGE ISSUES WITH MY TRANS. THIS IS DANGEROUS VERY DANGEROUS.

HAVE DOCUMENTED TRANSMISSION PROBLEMS SINCE THE PURCHASE OF THE VEHICLE. CONTACTED TOYOTA WITH MY CONCERNS, NO HELP WAS PROVIDED. TRANSMISSION FAILED. PROVIDED TOYOTA WITH COMPLAINT ON OCT.14,2015. AND MANY TIMES BEFORE THEN. AFRAID FOR MY LIFE TO DRIVE IT. TURNING, JERKING, HESITATION IN TAKE OFF. ETC.

MY TRANSMISSION HAS FAILED ON MY TOYOTA 2005 HIGHLANDER AFTER 96,000 MILES. I HAVE READ OTHER CONSUMER COMPLAINTS AND I AM CONVINCED THERE IS A SERIOUS PROBLEM WITH THE2005 TOYOTA HIGHLANDER HYBRID TRANSMISSION. I SPOKE TO TOYOTA AND THEY ADVISED ME TO TAKE MY CAR TO THE DEALERSHIP. I WAS TOLD THAT THE TRANSMISSION HAD TO BE REPLACED AND THAT IT WOULD COST $5060,00 TO REPLACE. TOYOTA OFFERED ME .10% OFF THE COST OF REPAIRS. I WAS SHOCKED AS I HAVE ONLY OWNED THE VEHICLE FOR 15 MONTHS AND HAVE A 4 YEAR NOTE. I AM VERY FORTUNATE THAT I DID NOT HAVE A HORRIBLE ACCIDENT AS I WAS COMING DOWN A VERY STEEP INCLINE ON THE HIGHWAY WHEN THE TRANSMISSION BEGAN TO FAIL. I AM FORCED TO REPAIR THE VEHICLE AS I AM NOT IN THE POSITION TO PURCHASE ANOTHER VEHICLE. I WOULD LIKE FOR THE NHTSA TO LOOK INTO THIS ISSUE FURTHER. *TR

ENGINE/TRANSMISSION IS VERY JERKY AND ON AGAIN OFF AGAIN WITH ACCELERATION AND DECELERATION. THIS HAS ALMOST CAUSED ME TO HAVE SEVERAL ACCIDENTS, AND I AM CONSIDERING GETTING RID OF THE CAR. IT SEEMS THAT TOYOTA HAS KNOWN ABOUT THIS PROBLEM WITH HIGHLANDER FOR SOME PERIOD OF TIME. AND I FEEL THAT THEY SHOULD HONOR THE HARD WORKING CITIZENS THAT BUY THEIR VEHICLES AND PROVIDE A RECALL TO REPAIR THE AFORE MENTIONED PROBLEMS. *TR

TRAVELING AT APPROX 35MPH THE VEHICLE SUDDENLY AND WITHOUT WARNING DECELERATED RAPIDLY TO ZERO MPH AND A LOUD GEAR - LIKE CRUNCHING AND GRINDING SOUND WAS HEARD UNDER THE ENGINE COMPARTMENT. THE VEHICLE WOULD ONLY MOVE AT 1 MPH TO PULL OFF THE ROAD AND WAS TOTALLY DISABLED. VEHICLE HAD TO BE TOWED. MECHANICS CONCLUDED THE FRONT DRIVE DIFFERENTIAL SUFFERED A MAJOR FAILURE AND THEN RUINED THE AUTOMATIC TRANSMISSION. *JS

TL* THE CONTACT OWNS A 2005 TOYOTA HIGHLANDER. THE CONTACT STATED THAT HE NOTICED TRANSMISSION FLUID LEAKING FROM THE TRANSMISSION. THE VEHICLE WAS NEITHER DIAGNOSED NOR REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 99,000. *TR

BOUGHT THE CAR USED WITH 49K MILES APPROXIMATELY. DID NOT DO THIS FOR THE FIRST 1.5 YRS WE OWNED THIS NOW PROBLEMS WITH THE TRANNY AND DEALER TOLD US IT IS SUPPOSE TO DO THAT. I DONT THINK SO BY OTHER PEOPLE IN THE TOYOTA HIGHLANDER FORUMS. THERE ARE THOUSANDS OF OWNERS WITH THIS TRANNY PROBLEM AND TOYOTA HAS NO FIX BUT TO REPLACE THE TRANNY FOR $5000.00 WIFE'S 2005 HIGHLANDER IS NOT SHIFTING CORRECT WHEN SHE SLOWS DOWN AND THEN TRIES TO SPEED UP OR WHEN SHE GOES AROUND A CORNER SLOW AND SPEEDS UP THE TRANNY HAS A DELAY AND THEN SHIFTS KINDA HARD. WHEN STARTING FROM A DEAD STOP SHIFTS FINE NO PROBLEMS JUST SLOWING DOWN AND THEN ACCELERATING IT WILL DELAY THEN SHIFT. IT KIND OF JERKS THE CAR AND MAKES YOU WONDER WHAT IS GOING ON. CAR HAS BEEN DOING THIS FOR ABOUT 6 MONTHS. THIS IS VERY DANGEROUS WHEN IN TRAFFIC WITH THE DELAY SHIFTING TRYING TO MERGE IN STOP AND GO TRAFFIC. MANY CLOSE CALLS OF GETTING INTO AN ACCIDENT. BEEN ON MANY FORUMS AND MANY PEOPLE HAVE BEEN TOLD BY THE TOYOTA DEALERS THAT THIS IS NORMAL WHICH I FEEL IS A BULL CRAP STORY JUST TO GET RID OF THE PERSON/COMPLAINT. I'M PUTTING IN THIS COMPLAINT BECAUSE IT IS A SAFETY COMPLAINT IN MY JUDGMENT AND TOYOTA NEEDS TO FIX THESE TRANNY PROBLEMS. THANKS *TR

I HAVE 2005 HIGHLANDER LIMITED V6 AWD. THE CAR HAS ISSUES WITH THE DIFFERENTIAL FLUID LEAKING AFTER 30,000 MILES OR EVERY TWO YEARS. THE DEALER FIXED THE LEAKING FOR MY CAR AT 35,429 MILES (NO CHARGE DUE TO WARRANTY) IN 2008; HOWEVER, THE DIFFERENTIAL WAS LEAKING AGAIN AT 67,329 MILES THIS YEAR. I CONTACTED TOYOTA AND THEY TOLD ME THAT THE WARRANTY FOR THE DIFFERENTIAL IS 5 YEARS OR 60,000 MILES, WHICHEVER COMES FIRST. ONCE THE VEHICLE IS OUTSIDE OF THESE WARRANTY GUIDELINES THE COST OF REPAIRS BECOMES THE OWNER?S RESPONSIBILITY. *TR

MY 2005 TOYOTA HIGHLANDER DEVELOPED A LEAK FROM THE TRANSFER CASE, WHICH HAS THE POTENTIAL TO CAUSE A COMPLETE LOSS OF TRANSMISSION FLUID AS WELL AS LOSS OF STEERING CONTROL. THERE ARE DOCUMENTED ACCIDENTS WHICH HAVE OCCURRED AS A RESULT OF THIS PROBLEM. THIS REPAIR WOULD NORMALLY BE COVERED BY A 5 YEAR/60,000 MILE POWER TRAIN WARRANTY HOWEVER THE LEAK WAS DISCOVERED A FEW MONTHS AFTER THE 5 YEAR TIME PERIOD EXPIRED. I HAVE SINCE LEARNED THAT TOYOTA WAS AWARE OF THIS POTENTIALLY DANGEROUS PROBLEM AND FIRST RELEASED A TECHNICAL SERVICE BULLETIN (TSB) IN NOVEMBER OF 2007 WITH THE MOST RECENT TSB BEING ISSUED MAY OF 2010. MY VEHICLE WAS CLEARLY UNDER WARRANTY AT THE TIME THAT THE TSB'S WERE INITIALLY ISSUED, BUT TOYOTA WITHHELD THIS INFORMATION FROM THE CONSUMER. THIS RESULTS IN A COST OF SEVERAL THOUSAND DOLLARS TO THE CONSUMER IN POTENTIAL REPAIRS. I HAVE CONTACTED TOYOTA CORPORATE HEADQUARTERS AND THEY REFUSE TO NEGOTIATE ANY TYPE OF REIMBURSEMENT FOR REPAIRS. TOYOTA HAS CONTINUED TO ISSUE TSB'S FOR THE SAME PROBLEM FOR 3 YEARS AND HAS APPARENTLY MADE NO ATTEMPT TO CORRECT THE PROBLEM DURING PRODUCTION. *TR

FRONT DIFFERENTIAL CATASTROPHICALLY FAILED ON 2005 TOYOTA HIGHLANDER (4WD) (65,220 MI) WHILE TRAVELING AT 65 MPH ON INTERSTATE. VEHICLE INSTANTANEOUSLY LOST SPEED (TO 30 MPH) & WE NARROWLY AVOIDED BEING RUN OVER BY SEMITRAILER AT HIGHWAY SPEED. DUE TO CONFIGURATION OF ROAD - ONLY SPORADIC SHOULDERS BECAUSE OF TERRAIN - THIS WAS A VERY DANGEROUS SITUATION. CAR STUCK IN TRAVEL LANES FOR AN EXTENDED PERIOD. FEEL VERY LUCKY THAT NO ONE WAS HURT. REPAIRING DEALER ASSERTED THAT THE PART HAD NO FLUID REMAINING DUE TO SEAL LEAK. VEHICLE WAS LAST SERVICED BY LOCAL DEALER ~2,000 MILES EARLIER (63,226 MI) WITH NO LEAKAGE SEEN. ENTIRE FRONT DIFFERENTIAL / TRANSFER CASE ASSEMBLY WAS REPLACED (STILL HAVE PART). CAR WAS TOTALLY INSPECTED BY REPAIRING DEALER AT THE TIME (65,220 MI) AND NO OTHER PROBLEMS FOUND. ONE MONTH LATER FOUND FLUID PUDDLE IN DRIVEWAY (66,216 MI). DEALER INVESTIGATED AND REPORTED THAT THE INSPECTION PLUG ON THE REAR DIFFERENTIAL WAS RAPIDLY LEAKING DIFFERENTIAL FLUID. TOLD NOT TO DRIVE VEHICLE TILL PLUG AND GASKET REPLACED. SEEMS TO BE OK NOW. SO, WITHIN A MONTH AND 1,000 MI USE, BOTH THE FRONT DIFFERENTIAL AND THE REAR DIFFERENTIAL RAPIDLY LOST FLUIDS. I SUSPECT BAD GASKETS WERE USED IN MANUFACTURE. *TR

I HAVE A 2005 TOYOTA HIGHLANDER AND THE TRANSMISSION HAS SLIPPED FROM ABOUT 45,000 MILES WHEN IT SHIFT FROM 3RD TO 4TH. TAKEN IT TO DEALER FOR UPGRADE ON ECM AND THIS DID NOT FIX PROBLEM AND IT IS GETTING WORSE. *TR

2005 HIGHLANDER V6 AWD. HAS A SURGING EFFECT SINCE DAY ONE. ALSO SURGES SLIGHTLY WHEN APPLYING BRAKES. IN TRAFFIC STOP AND GO SITUATION, VEHICLE DOES NOT RESPOND FOR A FEW SECONDS AND THEN LUNGES FORWARD. VERY DANGEROUS WHEN TRYING TO CHANGE LANES. DEALER SAID NOTHING WRONG WITH VEHICLE. TOYOTA SAID AT TIME TO CONTACT DEALER.

I OWN A 2005 TOYOTA HIGHLANDER. I WENT TO A FRIEND'S HOUSE AND PARKED VEHICLE IN FRONT OF THE HOUSE IN THE DRIVEWAY BY PLACING THE GEAR SHIFT IN THE PARK POSITION. I LEFT THE VEHICLE IDLING WHILE I WENT INTO MY FRIEND'S HOUSE TO GET A GROCERY LIST. I WENT IN AND OUT OF THE HOUSE ON 2 DIFFERENT OCCASIONS OVER A PERIOD OF ABOUT 10- 15 MINUTES TO RETRIEVE ITEMS FOR MY FRIEND THAT WERE OUTSIDE. ON BOTH OCCASIONS MY VEHICLE WAS IN THE DRIVEWAY IDLING. WHILE I WAS BACK INSIDE RETRIEVING THE GROCERY LIST MY FRIEND AND I OBSERVED MY VEHICLE MOVING THROUGH HER BACK YARD AND PROCEEDED INTO THE WOODS BEHIND HER HOUSE WHERE IT CAME TO A STOP AFTER HITTING A TREE. THIS VEHICLE SOMEHOW TOOK ITSELF OUT OF THE PARK POSITION AND INTO DRIVE!!!! I REPORTED THIS TO MY TOYOTA DEALER AND THE INSURANCE COMPANY. THE TOYOTA DEALER AND THE REGIONAL TOYOTA MANAGER SAID THERE WAS NO WAY THIS COULD HAVE HAPPENED AND THAT IT WAS NOT THE SAME ISSUE BEING INVESTIGATED (GAS PEDAL ISSUE). I WENT AHEAD AND HAD THE CAR REPAIRED AND THE INSURANCE COMPANY PAID FOR IT (EXCEPT FOR MY $500.00 DEDUCTIBLE) WITH NO INVESTIGATION OR QUESTIONS. I PICKED THE CAR UP TODAY AND NOW I AM HEARING ON THE NEWS THAT MANY OF THE SO CALLED GAS PEDAL INCIDENTS HAVE NOT BEEN EXPLAINED AND THAT IT IS POSSIBLE THAT MANY OF THE PREVIOUSLY REPORTED INCIDENTS CAN ONLY BE EXPLAINED BY A FAULTY COMPUTER. RIGHT AFTER THE ACCIDENT I ASKED THE TOYOTA DEALER/REGIONAL MANAGER SPECIFICALLY IF MY INCIDENT COULD HAVE BEEN CAUSED BY A COMPUTER MALFUNCTION. THE ANSWER WAS NO! *TR

MY 2005 TOYOTA HIGHLANDER V6 4WD, WHICH I PURCHASED NEW, HAS BEEN EXPERIENCING A HESITATION/SHIFTING PROBLEM FOR NEARLY AS LONG AS I HAVE OWNED THE VEHICLE. WHILE THE PROBLEM DOES NOT ALWAYS OCCUR, IT IS QUITE PRONOUNCED WHEN IT DOES AND HAS RESULTED IN VERY DANGEROUS SITUATIONS. THE PROBLEM HAS BEEN BROUGHT TO THE DIRECT ATTENTION OF TOYOTA MOTOR SALES IN CALIFORNIA, AND THEIR RESPONSE HAS BEEN DISTURBINGLY POOR. THE TOYOTA DEALER THAT HAS BEEN SERVICING MY VEHICLE HAS BEEN VERY HELPFUL, BUT APPARENTLY CANNOT TAKE ACTION TO CORRECT THE PROBLEM WITHOUT CORPORATE AUTHORIZATION. HERE IS A SUMMARY OF THE PROBLEM: THE VEHICLE CANNOT ALWAYS DECIDE WHEN TO ACCELERATE FROM A STOP - THERE HAVE BEEN MANY INSTANCES OF INITIAL HESITATION/LACK OF ADEQUATE POWER UPON APPLYING THE GAS PEDAL. FOR EXAMPLE, I HAVE EXPERIENCED A DELAY OF A SECOND OR TWO WHEN APPLYING THE GAS PEDAL TO PROCEED. THIS HAS RESULTED IN SOME VERY CLOSE CALLS WITH ONCOMING TRAFFIC. ALSO, THERE ARE OCCURRENCES WHERE THE VEHICLE CANNOT SEEM TO DECIDE BETWEEN GEARS (IT WILL SOMETIMES JUMP UP/DOWN BETWEEN THE LOWER GEARS, SUCH AS 1ST TO 2ND GEAR AND/OR 2ND TO 3RD GEAR). FURTHERMORE, I HAVE NOTICED A GENERAL LACK OF ADEQUATE ACCELERATION/GAS PEDAL RESPONSE, ESPECIALLY DURING CITY DRIVING (IE. LOWER SPEEDS). MY LOCAL TOYOTA DEALER HAS RECORDS OF THE PROBLEM SINCE APPROXIMATELY 16,000 MILES (THE VEHICLE NOW HAS ABOUT 44,000 MILES). I BELIEVE THE ISSUE IS THE ECM, WHICH WAS REPROGRAMMED BUT THE PROBLEM RETURNED. BASED ON MY RESEARCH, I BELIEVE THE ECM MAY BE DEFECTIVE AND THAT REPLACING THE UNIT MAY SOLVE THE PROBLEM. TOYOTA WILL NOT REPLACE THE ECM. ABOUT A MONTH AGO, THE TOYOTA DEALER WAS ABLE TO VERIFY THE HESITATION PROBLEM DURING A SERVICE VISIT. HOWEVER, THEY COULD NOT DUPLICATE IT LATER WITH THE SCAN TOOL ATTACHED - THEY HAD THE VEHICLE FOR TWO DAYS TRYING TO GET A SNAP SHOT BECAUSE THE TOYOTA FIELD SERVICE TECHNICIAN TOLD THEM "NO REPAIRS ARE TO BE MADE UNTIL THE PROBLEM OCCURS MORE OFTEN." TW*

AUTOMATIC TRANSMISSION IS FORCING FLUID OUT THROUGH VENT CAUSING LOSS OF FLUID AND POSSIBLE DAMAGE TO TRANSMISSION. DEALER SAID IT IS CAUSED BY BEARING GOING BAD IN THE TRANSMISSION. VEHICLE HAS ALMOST 90,000 MILES. DEALERSHIP SAID PROBLEM IS COVERED UNDER EXTENDED WARRANTY SINCE IT WAS A CERTIFIED USED VEHICLE. *TR

I HAVE A TOYOTA HIGHLANDER 2005 V6 4WD, WHICH SUFFERS FROM A TRANSMISSION SHIFT DELAY AND HESITATION ,WHICH NORMALLY OCCURS WHEN UPSHIFTING OR DOWNSHIFTING BETWEEN 2ND AND 3RD GEAR. THIS SHIFT DELAY IS NOT ONLY A HEADACHE, BUT A SAFETY CONCERN TO ME AND MANY OTHER FELLOW HIGHLANDER OWNERS AS SEEN ON VARIOUS ONLINE FORUMS. WHILE DRIVING MY VEHICLE I HAVE TO CONSTANTLY TRY TO ANTICIPATE HOW IT MIGHT REACT IN ORDER TO PREVENT AN ACCIDENT FROM HAPPENING,WHILE IN TRAFFIC. IT SEEMS AS IF THIS PROBLEM HAS BEEN KNOWN BY TOYOTA SINCE 2000 AND THEY HAVE NOT DONE ENOUGH TO GET IT FIXED. *TR

2005 TOYOTA HIGHLANDER WITH ONLY 72000 MILES (12,000 MILES OUT OF WARRANTY), SEALS ON TRANSFER CASE OF TRANSMISSION LEAKS ONTO EXHAUST PIPE CAUSING SMOKING AND SMELL OF BURNT FLUIDS. *TR

TL*THE CONTACT OWNS A 2005 TOYOTA HIGHLANDER. WHILE THE CONTACT SHIFTED THE GEAR INTO THE PARK POSITION, THE TRANSMISSION BEGAN TO JERK WITH HESITATION. THE FAILURE OCCURRED INTERMITTENTLY. THE VEHICLE HAD NOT BEEN DIAGNOSED OR REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 29,000.
