2017 TOYOTA HIGHLANDER Power Train Problems

I had problems in gear shift the car when start moving it’s go very slow it’s need about 1 minute to change the shift. The Toyota dealership recommended me to change the transmission with the cost $11,000

-- What component or system failed or malfunctioned, and is it available for inspection upon request? This report is regarding a premature transmission failure in our 2017 Toyota Highlander equipped with the UA80F 8-speed automatic transmission. Our highlander is currently stuck at High Tech Automotive in Wenatchee, WA 150+ miles from home after experiencing a transmission failure on the highway. -- How was your safety or the safety of others put at risk? During the transmission failure while driving on the highway the Check Engine Light came on as well as ABS light and vehicle went into a limp mode. The transmission failure and subsequent limp mode rapidly decreased our speed while traveling on the highway and forced us to limp the vehicle at low speeds across traffic putting ourselves and others traveling on the highway at risk. This vehicle has been well maintained and serviced in accordance with Toyota’s recommended maintenance schedule. Despite this, the transmission failed unexpectedly during a recent family road trip to Wenatchee, WA, leaving us stranded far from home. -- Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the vehicle was towed to High Tech Automotive in Wenatchee WA (where it is currently stranded). The diagnostics report there confirmed proper transmission fluid level and a failed transmission with burnt transmission fluid. -- Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Not yet. A request for assistance was sent to Toyota today. -- Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There were no warning lamps, or messages. We've had the vehicle maintained and there was a whirring sound which we had inspected at Dougs Auto Tune and Repair thinking it could be the timing chain or alternator but there was no indication of transmission issues.

I own a 2017 Toyota Highlander with 6 cylinders (engine model 2GR-FKS). It has 107,000 miles. I brought it to my dealer for inspection and service, and noted that it was making a whirring/whining sound upon acceleration. There were no warning messages on the dashboard to alert me of any issues. The dealer reported back to me that the transmission was failing and quoted $11k to fix it. Upon researching this issue, I learned that this is a known problem with 2017 model Highlanders.

Vehicle shurtter cause toque converter issue with all Toyota Highlander

Was on drive from work in 2017 toyota highlander XLE. Noticed low whining sound coming from transmission. Made appointment with toyota dealership. They identified transmission whine as requiring full replacement and projected to fail soon. Vehicle mileage was at 116k miles. There are no ua80 trans available in US and none coming in. Was told my VIN didn't qualify for CRP CJZ and TSB bulletin. The UA80 trans has known failure of this type. Replacement cost is 10K, use is dangerous, and failure is unacceptable.

After less than a year of usage on a Highlander with 70k miles, the transmission began malfunctioning. The reverse function would work sporadically. The gears would shift only when using the power stick function and manually switching gears. The transmission would go into overdrive and once after an oil change the car came to an abrupt stop after traveling 25 mph hour.

Transmission when the car first starts up is slipping. No dipstick for checking Transmission fluid.

The transmission is experiencing harsh and sometimes delayed shifting and sometimes reduction of power. This can result in unpredictability when going from a stop and then crossing traffic. If the transmission fails while I am making an unprotected left turn it pups leave me vulnerable to side impact from on coming traffic. The dealer was able to reproduce the issue when I took it in and quoted me $11k for repair. Toyota is an aware of issues with this specific transmission (UA80) and issued a Service Bulletin for it. My transmission fell within the serial number range for replacement but didn’t pass the third gate for coverage related to a speed sensor issue. That said, there is massive back order on this transmission highlighting a much broader problem with the part. To answer the final question, I never saw a warning light.

Transmission failure causes vehicle to not accelerate in low gears. Toyota has a CSP for this issue on the same model year but this "Vin" Is not a part of it. This is a major safety issue.

2017 Toyota Highlander XLE Why hasn’t Toyota issued a recall?! My transmission failed at 2AM on the Florida turnpike 140 miles from home, after a physically and emotionally exhausting day moving my daughter to college. I slept in my car 7 hours, scared, waiting to get towed. The closest shop that was open early on a Saturday was an hour away in the other direction and when I got there, they told me they wouldn’t be able to look at it until Monday. Pointless to pay 2 nights at a hotel, so I got an Uber to get a rental to get home. It wasn’t bad enough when I found out the cost to replace the transmission on a car with 96k miles (my Camry had 300k when I sold it), but even if I agreed to pay, the transmission is backordered, and it could be months. Months! I had to pay the diagnostic fee - completely understandable - and I needed it moved to avoid a $75 per day storage fee. AAA would tow it 100 miles, then $7.00 per mile. When I asked to speak with someone because I had the upgraded membership that provided 200 miles, I was told they wouldn’t cover any part of the tow because it was already at an auto shop. The least expensive option was to get a transport company ($300) to pickup and deliver the car to the local Toyota dealership. They’re anticipating at least 3 months, but they’ll pay for a rental if I agree to have them do the repair. Has Toyota fixed the issue, or will the new transmission likely to have the same problem?

TRANSMISSION ON THIS VEHICLE FAILED AND CAUSES SUDDEN DECELERATION CAUSING A SAFETY ISSUE. SUDDEN DECELERATION. YES, TOYOTA OF VERO BEACH HAS CONFIRMED FAILURE OF THE TRANSMISSION. NO, WARNING JUST FAILED THEN GOT ALL THE WARNINGS AND LIGHTS IMMEDIATELY THEREAFTER.

Transmission whining, harsh shifting, delayed acceleration

Car suddenly began to slip out of gear and have difficulty shifting smoothly. After having car examined by 2 repair shops it was determined the UA80 Transmission needed replaced. Repair shop advised car was not safe to drive with this condition. Warning lights for Check Engine and Check AWD system and traction control came on at the same time as the slipping and rough shifting.

The transmission on my Highlander is making a whining noise. I took it to Blackstone Toyota Service for inspection, in Fresno, CA, after my own mechanic inspected it and told me that it was a transmission problem. Toyota told me that the transmission is going out and the car can quit on me at any time and is no longer safe to drive. But since it is out of warranty now they will not do anything to help me with this problem. There has been no warning lamp, message or other symptoms yet. After my service in Nov. 2023 i noticed a slight whine when i accelerated. I had a friend mechanic look at it and he said it could be just because the tires had been rotated. A couple of months ago the whine started on deceleration. I took it to Johnson Auto in Clovis, CA and they were the first ones to tell me it was in fact a transmission problem. I then called Toyota call center and was told that the vehicle needed to be inspected by one of their dealers, and then they could help me. I explained that I didn’t want to go spend more money on the inspection if Toyota would not do anything to help me, I already knew it had transmission problems. I took it to Blackstone Toyota Service Center and they confirmed that the transmission is going out, at only 7800 miles. I called the Toyota call center and was told that since it is out of warranty they will do nothing to help me with this problem. I told them the prior agent I had spoken to said that Toyota would help me. I was told they will do nothing else to help and there was no one else I could talk to about the transmission problems. I was told that they didn’t know of any problems with the 2017 Toyota Highlander and that there were no recalls. I told them that there were lots of complaints about the Toyota Highlander online and I was surprised that they didn’t seem to know anything about the Highlanders having transmission problems. Many people in my same circumstances with expensive repairs way too soon on their Highlanders.

My 2017 Highlander XLE AWD had complete transmission failure at 106,000 miles. Toyota has an extended coverage warranty for this but according to them my VIN number was not included even though it failed for the same reason as the recalled transmissions. Loud whining started around 100,000 miles on acceleration around 30mph and continued to get louder. From a dead stop it is very slow to accelerate and misses 3rd gear and jerks. There is a TSB out on this and the extended customer satisfaction extended warranty ZJC but they refuse to cover. I was also told by Toyota corporate that even if my VIN was affected they would not cover due to all maintenance not being done at a toyota dealership. I am the 4th owner and should not be penalized for this. My case number with Toyota is Toyota Brand Engagement Center Case 250416002071

Known issue with the transmission assembly that results in a whining noise and eventually hard shifting and transmission failure. Known issue acknowledged by Toyota across this model and date, but they seemingly are only addressing some vehicles - and not others - with said known issue.

Transmission failure requiring replacement. Known pattern failure from Toyota. Customer support program from Toyota does not cover all affected vehicles.

Transmission intermittently allows the RPMs to double from 2,000 to 4,000 RPMs. It occasionally displays trouble codes, and exhibits a grinding, whirring noise. An Independent transmission shop confirms that it needs to be replaced. Toyota has issued a recall referred to as Customer Support Program ZJC, but their representatives claim that our vehicle does not qualify, even though the date and model of the transmission clearly Falla under their parameters.

The contact owns a 2017 Toyota Highlander. The contact stated that the vehicle was parked but still running in a driveway on an incline. After exiting the vehicle, there were abnormal beeping and ticking noises detected, and the vehicle began to roll down the street. The contact and daughter were pinned between the door and the vehicle. The contact's daughter sustained injuries to her chin and teeth. The driver has lumps and bruises on her leg and back pain, but medical attention was not provided. The rear wheels were on the curb and hit a trash can, and the vehicle stopped rolling. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 70,000.

Mileage: 70,000

In city driving, vehicle began exhibiting slightly delayed shifting from 1-2 and 2-3. Downshifts from 3-2 seemed slightly rough. Approximately 5 minutes later when accelerating from a stop on an uphill grade, the shift from 2-3 was delayed (2nd gear disengaged, engine speed increase ~1000RPM, then shifted to 3 abruptly). At next stop, lower gears where not available. Vehicle seemed be in 4th(?) gear when accelerating from a stop. Very little power available. Had to engage hazard flashers and other vehicles navigated around our vehicle. Managed to limp car ~ 1 mile to home. Approaching driveway, Master Warning Light, Check Engine Light and 4WD Warnign light all illuminated. This issue created a loss of power that impaired the drivers ability to maintain a safe speed relevative to traffic. Had this issue occurred during high-speed operation, the vehicle may have been disabled in a high-risk area. Transmission appears to be unreliable.

2017 Toyota Highlander experienced delayed and rough shifting in 3rd gear. Safety of acceleration is affected, especially merging onto highways. Diagnosed with bad transmission on 12/26/2023 by Toyota service. There was no warning lamps or messages prior to failure. Unknown cause, car is regularly serviced per manufacturer recommendations by Toyota. Part on backorder for approximately 3 months.

There is a toyota service bulletin for known transmission issues with this vehicle. I had noticed that my gears weren't shifting properly. The dealer checked vehicle and said transmission was bad, and that toyota would replace it, for free. However, the part would take one month to arrive. This all occurred on 1/9/2024. I was told by the dealer that Toyota would not cover a rental car while the part was on order, but only for the repair itself. The dealer told me the Toyota recommendation was to not drive the vehicle -- but other customers had done so until they received their parts for repair. I picked up my vehicle after work at approximately 7:15pm. While driving, the vehicle completely shutdown on me in a major highway miles from downtown Philadelphia, in a flooding rainstorm that produced nearly 4 inches of rain. If Toyota knows there is a problem with this vehicle and its transmission, then why is there no recall? And if I'm being told the I should not drive the vehicle, then why isn't it mandated or required for them to provide me a rental - especially since this is the fault of Toyota?

Highlander shift issue 11/14/2023 On 11/14/2023, our 2017 Toyota Highlander, vin# [XXX] , upon driving the transmission decided on its own to disengage. Our Highlander stopped propelling itself in either direction. We had to manually push our vehicle into a parking spot and await the tow truck. Our Highlander is in mint condition with 71,400 miles on it. This was scary because the vehicle would shift on the shifter, but for some reason the transmission would not engage. The engine worked perfectly fine. We had the Highlander towed to the nearest Toyota dealer who pushed the vehicle into their garage and placed on a lift. The Highlander had no idiot lights on, no cable issues, fluid was fine per the Toyota Technician. The Toyota Tech placed the vehicle on their main computer and there were no error codes. The Tech reset the computer on the vehicle with a Toyota Master computer, and the vehicle started to work as normal. I consider this a huge issue and I thank God that my wife was not on the interstate highway when this happened.

About two weeks prior to the transmission failing, I started hearing a high-pitched whining coming from the transmission, difficulty shifting, and lurching forward when engaging the gear. On the evening of October 4th, my wife was driving at 65 mph on a busy freeway in Atlanta when the vehicle lost acceleration. She was nearly hit while stopped on the freeway. Fortunately, kind motorists got out of their cars and pushed her to the side of the road. The car was towed to a Toyota service shop, and we were advised they could not do the repairs. The mechanic stated it was a known internal Toyota issue. I did some research online and found hundreds of posts from Highlander owners of 2017-18 vehicles complaining about issues with the transmission failing. I found Toyota Customer Support Bulletin POL [XXX] dated 4/18/2019, REPAIR COVERAGE FOR UA80 TRANSMISSION ON CERTAIN 2017-2018 MY SIENNA AND CERTAIN 2017-2018 MY HIGHLANDER VEHICLES. The mechanic said the failure code with a failed transaxle and all the symptoms my vehicle experienced were consistent with the bulletin. My time period for the bulletin was for cars produced from November 2016 to December 2017. My vehicle’s manufacturing date was 12/8/2016. Toyota claims my vehicle although produced during this time was not impacted. It is my belief that Toyota was aware of multiple failures on UA80 transmissions on vehicles produced from 2016 to 2020 and deliberately identified a smaller number to avoid a recall.

Driving on the highway vehicle suddenly drop speed. I was able to exit but not proceed forward once exiting. The vehicle was towed and diagnosed with need for new transmission. There was a customer support program bulletin POL 19-04 noting similar problems. However, Toyota is stating this 2017 is not associated with the program. The whine noise and reduced power are all listed with this program. The vehicle sudden reduce power may have resulted in a major accident on busy Atlanta highways. A known transmission issue that Toyota is not willing to support customer in resolving is unbelievable. I was basically told because the vehicle was not serviced at a Toyota dealership regularly, they cannot support.

Several times on the highway when getting up to speeds around 70mph the transmission would rev but not accelerate or maintain speed - usually slowing to around 40-50mph or slower depending on the hill grade. The check engine light came on, initially was told it was probably a fluke. The mechanic couldn’t get it to do the same thing for him. Brought it back again when the issue persisted. He suspected the transmission was slipping, referred me to the dealer. The light was off by then, the dealer said they couldn’t diagnose with no light so we needed to wait until it came on. It finally came on while driving on I71 but the car completely lost all power and I was stranded on the side of the highway and had to be towed to the dealer. I did a quick google search and saw a class action suit for this vehicle and year in which the plaintiffs complained of the same issues. Toyota opened an extended warranty on vehicles with this transmission. I called Toyota to see if my VIN was included and they confirmed it is. The person I spoke with (“Cannon”) assigned case # 20612000768. Per the dealer, my vehicle only met half of the criteria to be included under the program. We were stuck with a $6,149 bill to replace the transmission. The dealer won’t even guarantee it for 30 days because it’s a used Toyota transmission, which to me speaks volumes.

Transmission lost power while driving and began to slip. Had to pull over immediately. Check engine light illuminated. Happened again several more times before I was able to take to dealer. Dealer was able to reproduce and diagnosed as transmission failure requiring replacement for $10k. Due to the low miles and age (6 years, 3 months) I requested that Toyota help cover costs which they declined to do. This is a dangerous situation and I believe Toyota should have fixed as goodwill.

Transmission problem in our 2017 Toyota Highlander started at 104k miles. unfortunately for us out of warranty and lucky for dealer and manufacture who shifted the cost to consumer outside warranty. We experienced delayed and sudden shifting, slow at accelerating. One day the engine kept revving but car was not moving. Also reverse gear stopped working. We brought the car to local dealer, who gave us every excuse in the world that it was our driving habit, we take it off roading etc etc. The truth I am a very careful driver which I am sure the dealer laughed at me for saying that. Never took the car off roading, or on monthly long trips. All services were completed by the dealer. The quoted us a cost of $9500 plus tax plus $250 diagnosing fee. Also reported the issue to Toyota consumer line, got the same answer car is outside warranty and no cost sharing as no official recall has been issued. Upon doing some research, we came across similar issues reported by same model. The sad part is local dealership was fully aware of similar issue, yet they failed to warn customers or suggest necessary repairs while the car had full warranty. A tech at dealer even said, they are not going to suggest it as in that case the repair would have to be done at dealers expense. How, is this ethically right to leave the consumer in dark, at risk on the road and blame the problem on bad driving habit? This is perfect case of bad dealership and a company hiding their problem. Wait till actually someone dies to issue a recall?

On March 9, 2022, the transmission in my 2017 Toyota Highlander completely failed while I was driving on a busy road during rush-hour traffic. I was approaching a stop light and was braking when the vehicle lunged forward and then stopped moving. I pressed the accelerator to move up to the stop light but the vehicle would not move, even though it was in Drive gear. I changed the gear to Park and then back to Drive and the vehicle still would not move. The engine was revving and the RPMs were increasing but the vehicle would not move while in Drive gear. I also tried to reverse but the vehicle still would not move. I had to exit the vehicle and ask for assistance from other motorists to physically push my vehicle off the road into a parking lot so as not to continue blocking the busy road. I called for a tow truck which towed my vehicle to Scott Clark Toyota City dealership in Matthews, North Carolina. They inspected the vehicle and the next day let me know that transmission had completely failed. They added that they had never experienced this and it was especially unusual on such a new vehicle. The vehicle was only 5 years old and only had 45,000 miles with no prior issue or warning. We bought the vehicle new in 2017 and it has been serviced regularly by a Toyota dealership. Thankfully, the vehicle was still under factory warranty and the transmission was replaced at no cost to me.

When the vehicle was ~1.5 years old following its 10,000 mile maintenance, substantial thumping generated from the rear of the vehicle. Each time, the dealership attempted to resolve the problem finding issues with struts; however, it only went away in late March after having the vehicle in the shop for weeks at a time on 5 different occasions Nov 2018 - Mar 2019. I engaged Toyota HQ (800-331-4331) - filing report #1901092572 - requesting an exchange of the vehicle. This was denied and I was offered a 8 year warranty. *Due to COVID, I rarely drove this vehicle through 2020 and most of 2021, where to date, I have only ~34,000 miles on the vehicle. -On 21 Oct 2021, my wife was stopped at a gas station and attempted to start the vehicle. The vehicle would not start and the following lights came on without previous warning: 1)Braking Power Low, 2)Maintenance needed soon, & 3)Orange yellow triangle lit up with exclamation mark. My wife was stranded for 3 hours and the vehicle had to be towed. The dealership informed me that Toyota installed a generic battery into the vehicle (when being sold) that was only to have 4-5 years of life; however, my concern was that this vehicle had just completed maintenance and there was no warning of this upcoming issue. When repaired, I had to pay for the name brand (True Start) battery. -On 16 Jan 2022, after having driven the Highlander for 25 minutes, I started the engine while in a parking lot. While moving forward and the engine still going, the brakes and power steering went out. On the dashboard, the same lights that came on in Oct 2021, did so again. I had to let the vehicle coast (having no control) with my wife and child in the car through the parking lot. It came to a stop at the concrete parking curb stop at a store front. Toyota stated that since there was no check engine light that there was no code and they could not duplicate the problem. The vehicle was sent back to me with no resolution or explanation.

The car jerks upon acceleration. It is so pronounced that it causes whiplash in driver and passenger

ON 3 SEPARATE OCCASIONS AT 30,000, 40,000 AND 42,000 MILES WHEN DRIVING AT INTERSTATE HIGHWAY SPEEDS (AROUND 70 MPH) WITH CRUISE CONTROL ENGAGED, THE VEHICLE HAS SUDDENLY WITHOUT WARNING SWITCHED TO A LOW POWER LIMP HOME MODE RESULTING IN RAPID DECELERATION IN THE MIDST OF HIGH SPEED HIGHWAY TRAFFIC. I BELIEVE THIS IS A VERY DANGEROUS SITUATION. MULTIPLE WARNINGS APPEARED ON THE DASH INCLUDING LOW POWER MODE, CHECK AWD SYSTEM, AND SEE YOUR DEALER. SHUTTING OFF THE VEHICLE AND RESTARTING IT ALLOWED THE VEHICLE TO BE DRIVEN NORMALLY AGAIN. AFTER ALL THREE INCIDENTS THE VEHICLE WAS TAKEN TO THE DEALER FOR DIAGNOSIS. ALL 3 TIMES THE COMPUTER HAD STORED CODES FOR RANDOM MULTIPLE MISFIRES ALONG WITH A FEW OTHERS. ALL THREE TIMES THE DEALER INDICATED THAT THE CODES DID NOT POINT TO A SPECIFIC FAULTY PART THAT THEY COULD REPLACE, SO THERE WAS NOTHING THEY COULD DO. AT MY INSISTENCE THAT SOMETHING BE DONE AFTER THE THIRD INCIDENT THE DEALER OPENED A CASE WITH THE TOYOTA TAS SYSTEM TO ASK FOR ASSISTANCE IN DIAGNOSES. THE ONLY RESULT OF THIS WAS TO SWITCH SOME OF THE COIL PACK POSITIONS TO SEE IF THE MISFIRES FOLLOWED THE COIL PACK. THE END RESULT IS THAT I HAVE TO DRIVE IT UNTIL IT FAILS AGAIN, PUTTING MYSELF AND OTHERS AT RISK. I ALSO OPENED A CASE WITH THE TOYOTA CUSTOMER EXPERIENCE CENTER, THEY CONFIRMED THIS WAS ALL TOYOTA WOULD DO AT THIS POINT.

AT 62K MILES I NOTICED A LITTLE PINK ON GARAGE FLOOR AND HAD A MECHANIC LOOK AT THE PROBLEM AND FOUND I HAD A INLET WATER THERMOSTATIC HOUSING LEAKING. HE INSTALLED NEW ONE AT MY COST. POWER TRAIN WARRANTY WAS UP TO 60K MILES. FOUND A FEW DAYS LATER STILL LEAKING AND THIS TIME WATER PUMP. COMBINED COST FOR 2 REPAIRS AT LOCAL TOYOTA WAS RIGHT AT $1600. I BOUGHT THIS NEW AND PRIOR TO THIS I HAVE HAD GREAT SERVICE FROM MY TOYOTAS. THOUGHT CORPORATE TOYOTA WOULD TAKE CARE OF THIS BUT NO WAY. I HAVE SPOKE TO SEVERAL OTHER OWNERS OF THIS YEAR INCLUDING RAV OWNERS AND THEY HAD SAME ISSUE. HOPEFULLY TOYOTA RECALLS THESE WATER PUMPS BECAUSE NO NEW CARS WATER PUMP SHOULD GO OUT LESS THAN 100K MILES, THIS VEHICLE COST ME $48K AND WHAT A WASTE OF MONEY. WHEN I CALLED TOYOTA YESTERDAY TO CHECK TO SEE IF THERE WAS A RECALL THEY SAID NO BUT THERE WAS A CAMPAIGN FIX ON A OIL HOSE, EVEN THOUGH I WAS REGISTERED WITH THEM THEY DID NOT NOTIFY ME OF THIS CAMPAIGN. I WILL FILE COMPLAINTS WITH VARIOUS ADVOCATES FOR CONSUMERS, THIS IS VERY UNSATISFACTORY ESPECIALLY FOR TOYOTA AND MY WALLET. BOOH TOYOTA..!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

WHILE COMING TO A STOP AT A RED LIGHT, THE VEHICLE STARTED JOLTING LIKE IT WAS GOING TO SHUT OFF. ONCE AT A FULL STOP, THE CAR DID NOT SHUT OFF. INSTEAD, ONCE I LIFTED MY FOOT OFF THE BREAK, THE VEHICLE WOULD NOT MOVE. I SHIFTED INTO PARK, BACK TO DRIVE, REVERSE, AND EVEN MANUAL BUT THE CAR WOULD NOT MOVE. I WAS STUCK ON A ROAD WHERE CARS DRIVE 60-70 MPH IF THE LIGHT IS GREEN I WAS AFRAID THAT I WOULD BE READ-ENDED. I WAS HELPED BY A GOOD SAMARITAN OFF THE ROAD AND WAS FORCED TO TOW THE VEHICLE TO MY HOUSE. NEXT MORNING, THE CAR STILL WOULD NOT MOVE AND WAS FORCED TO TOW IT TO THE TOYOTA DEALERSHIP. OUTSIDE OF SOME IRREGULAR DOWN-SHIFTING, THE DEALER COULD NOT DUPLICATE THE PROBLEM. ULTIMATELY, THE SYSTEM WAS REBOOTED AND THE VEHICLE WAS RETURNED TO ME AFTER I TEST DROVE IT WITH THE SHOP FOREMAN. BECAUSE THE PROBLEM WAS NOT DIAGNOSED, I FEEL UNSAFE DRIVING THE VEHICLE AND AFRAID THAT PROBLEM MAY REOCCUR, LEAVING ME IN A DANGEROUS SITUATION. THE DEALERSHIP ITSELF WAS VERY HELPFUL BUT THEY RELIED ON CORPORATE TOYOTA TO GUIDE THEM WITH DIAGNOSING AND FIXING THE PROBLEM. IT SEEMS THEY CAME UP SHORT.

ON SUNDAY OCT 21 2018, THE DRIVER HAD JUST LEFT THE OLIN REST AREA IN NORTH CAROLINA, HEADING NORTHBOUND ON RT 77. AFTER DRIVING FOR A LITTLE BIT THE CAR SUDDENLY ACCELERATION UNINTENTIONALLY BY ITSELF. AND THE CAR STARTED TO ZIG ZAG ACROSS THE HIGHWAY LANES WITHOUT THE DRIVER TURNING THE STEERING WHEEL. THE DRIVER TRIED TO PRESS ON THE BRAKE BUT IT WAS NOT EFFECTIVE. THE CAR THEN GRAZED AN HIGHWAY GUARDRAIL AND IT PARTIALLY RIPPED OFF THE REAR LEFT SIDE AND REAR BUMPER. THE DRIVER KEPT PRESSING THE BRAKE WITHOUT EFFECT WHILE SWERVING ACROSS THE LANES. THEN SUDDENLY THE BRAKES STARTED TO WORK AND THE DRIVER WAS ABLE TO BRING THE CAR TO A STOP ON THE RIGHT SHOULDER. THE DRIVER PUT IT INTO PARK BUT THE ENGINE KEPT REVVING AT HIGH RPM UNTIL THE DRIVER TURNED OFF THE ENGINE. I THINK THE CAR HAD A SUDDEN UNINTENDED ACCELERATION INCIDENT DUE TO THE ELECTRONIC THROTTLE CONTROL. IN ADDITION, I THINK THE ZIG ZAG WAS DUE TO THE ELECTRONIC TRACTION/ STABILITY CONTROL, SENDING EXCESSIVE POWER TO A WHEEL ON A PARTICULAR SIDE OF THE VEHICLE WHEN IT DIDN'T NEED IT.

TRANSMISSION FAILURE. TOYOTA REPLACED ENTIRE TRANSMISSION

HELLO, THERE. I WANT TO SHARE MY EXPERIENCE ABOUT HIGHLANDER PROBLEM. MY WIFE AND ME WENT TO MYSTIC,CT FROM MY HOME FOR PLEASURE AUGUST 8. I USED CRUISE CONTROL WITH 65 MPH ON HIGHWAY. AFTER I FINISHED TRAVELING THERE, I TRIED TO USE THE SAME CRUISE CONTROL ON THE WAY HOME. AND THEN SUDDENLY MY CAR MADE PROBLEM IN THE MIDDLE OF DRIVING ON HIGHWAY. RPM WENT UP TO OVER 3000 AND RPM NEEDLE ON DASHBOARD STARTED DANCING. AND I WATCHED 'CHECK AWD SYSTEM','TRACTION CONTROL TURNED OFF','CHECK ENGINE VISIT YOUR DEALERSHIP' COMING UP. AUTOMATICALLY MY CAR LOST POWER CONTROL. WE WERE VERY SCARED BECAUSE EVERYONE THERE WAS DRIVING A CAR WITH HIGH SPEED AT NIGHT. I TURNED ON EMERGENCY LIGHT AND PUT MY CAR ON SERVICE ROAD. FORTUNATELY, NO BODY FOLLOWED BEHIND MY CAR AT THAT TIME. IF SOMEONE KEPT APPROACHING MY CAR,WE WOULD HAVE MADE BIG TRAFFIC ACCIDENT. THIS IS SAFETY ISSUE FOR US. EVEN IF WE ARE STILL ALIVE, I DON'T HAVE ANY COURAGEOUS IDEA ABOUT MY CAR. I WILL NOT BE SATISFIED WITH MY CAR. WHENEVER I DRIVE IT, I HAVE TO THINK ABOUT MY CAR CONDITION. FOR EXAMPLE, I FOUND THE SAME STORY ABOUT MY HIGHLANDER THROUGH CARCOMPLAINTS.COM THAT CAR WAS EVENTUALLY BURNED IN THE MIDDLE OF HIGHWAY. SO I WANT MY MONEY BACK BY LEMON LAW.

SINCE I LEASED BY HIGHLANDER I HAVE NOTICED THAT THE CAR SHIFTS VERY HARD, SOMETIMES SPUTTERING BETWEEN 5-10MPH AND THEN ACCELERATING. DEALER REFLASHED THE COMPUTER BASED ON TECHNICAL BULLETIN TSB-0194-17. THEY HAVE NOW HAD THE CAR FOR 3 DAYS AND HAVE REPLICATED THE ISSUE AND I AM AWAITING GUIDANCE. THE VEHICLE HAS 13,000 MILES ON IT, THERE SHOULD NOT BE MAJOR TRANSMISSION ISSUES. MY COMPLAINT DOESN'T SEEM ISOLATED.

AT ABOUT 11,000 MILES, A HIGH PITCH WHINING SOUND APPEARED DURING ACCELERATION. THE DEALER IDENTIFIED A PROBLEM THAT REQUIRES A NEW TRANSMISSION. THE PARTS ARE BACK ORDERED. I WAS ADVISED TO CONTINUE TO DRIVE THE CAR UNTIL TOYOTA APPROVED THE REPAIR AND THE PARTS WERE AVAILABLE. RESEARCH INDICATED THAT THIS ISSUE IS COMMON AND MAY LEAD TO COMPLETE TRANSMISSION FAILURE PRESENTING A SAFETY ISSUE.

4 WEEKS AGO THERE WAS A NOTICEABLE HIGH PITCHED WHINE DURING ACCELERATION FROM 40 MPH AND UP. THE WHINE'S PITCH WOULD CHANGE UP OR DOWN WHEN THE AUTOMATIC TRANSMISSION CHANGED GEARS AND THE VEHICLE'S SPEED CHANGED. ON 2/12/2018, THE TRANSMISSION LET GO (THE ENGINE WOULD REV, BUT NO POWER TO THE WHEELS) WHILE MY WIFE WAS DRIVING ON A BUSY 45 MPH STREET. FORTUNATELY, THE PERSON BEHIND HERE DIDN'T REAR-END HER AND MY WIFE WAS ABLE TO PULL THE VEHICLE INTO A TURNING LANE AND STOP WITH FLASHERS ON. SHE TURNED THE VEHICLE OFF AND ON. THE TRANSMISSION ENGAGED AND SHE WAS ABLE TO DRIVE THE VEHICLE HOME. RIGHT BEFORE THE TRANSMISSION LET GO, SHE HEARD A GRINDING NOISE. WHEN I DROVE THE VEHICLE TO THE DEALERSHIP, THE WHINE WAS GONE ON ACCELERATION, BUT NOW IT WOULD WHINE ON DECELERATION! THE MECHANIC AT THE DEALERSHIP DETERMINED THE TRANSMISSION NEEDED TO BE REPLACED DUE TO AN INTERNAL CLIP THAT BECOMES UNSEATED. THE CLIP CAN CAUSE INTERNAL DAMAGE TO THE TRANSMISSION. THEY WERE WORKING ON ANOTHER HIGHLANDER WITH THE EXACT SAME PROBLEM. THERE IS A CONVERSATION PUBLISHED ON EDMUNDS.COM WITH OTHER PEOPLE REPORTING THE SAME ISSUE I HAD WITH MY HIGHLANDER'S 8-SPEED AUTOMATIC TRANSMISSION. MY HIGHLANDER HAD 13.200 MILES ON IT WHEN I TOOK IT TO THE SHOP. IT TOOK 9 CALENDAR DAYS TO GET THE VEHICLE FIXED DUE TO LIMITED AVAILABILITY OF THE TRANSMISSION. THE DEALERSHIP TOLD ME MY REPLACEMENT TRANSMISSION WAS THE ONLY ONE IN THE COUNTRY (USA) WHEN THEY ORDERED IT! IF THIS IS HAPPENING WITH SO MANY HIGHLANDERS WITH THIS 8-SPEED AUTOMATIC TRANSMISSION, IT'S JUST A MATTER OF TIME BEFORE A SERIOUS ACCIDENT RESULTS FROM THE TRANSMISSION FAILING ON SOMEONE ELSE.

AS I WAS TURNING LEFT AT A GREEN ARROW ACROSS A DIVIDED HIGHWAY, THE CAR STOPPED MOVING IN THE MIDDLE OF THE INTERSECTION. THERE WERE NO WARNING LIGHTS OR ALARMS IN ADVANCE OF THE STOP, NOR WERE THERE ANY CRUNCHING OR GRINDING SOUNDS AT THE TIME THE CAR STOPPED. I COULD TELL WHEN I STEPPED ON THE ACCELERATOR AT THE TIME THE LIGHT TURNED GREEN THAT SOMETHING WASN'T RIGHT. AFTER THE CAR STOPPED, I TRIED TO RE-START 2X IN THE INTERSECTION, THEN PUSHED THE CAR OUT OF THE INTERSECTION. THE LIGHTS AND ELECTRICAL CAME ON, BUT WHEN I PUT IT IN GEAR AND HIT THE ACCELERATOR, THE ENGINE REVVED AND THE RPMS WENT UP, BUT THE TIRES DID NOT ENGAGE. TOYOTA DEALERSHIP WITH CALLS TO TOYOTA ENGINEERING TOOK 2 DAYS TO DIAGNOSE IT AS A TRANSMISSION " PRODUCTION ERROR" THAT REQUIRED A "COUNTERMANDED" REPLACEMENT. THEY HAVE HAD THE CAR IN FOR SERVICE FOR OVER 30 DAYS. I WAS CONTACTED LAST FRIDAY THE 12TH TO BE TOLD THAT THE REPLACEMENT PART WAS IN, BUT HAVE NOT BEEN CONTACTED TO PICK UP.

WHILE DRIVING UP THE I-5 GRAPEVINE AT 72 MPH THE CAR SUDDENLY SLOWED WITHOUT ANY WARNING TO UNDER 20 MPH. THE CHECK ENGINE LIGHT TURNED ON AND THE DASH SAID AWD SYSTEM DISENGAGED OR ERROR OR SOME SIMILAR MESSAGE AND TO TAKE TO THE DEALER. I WAS BARELY ABLE TO ACCELERATE TO GET OFF THE ROAD. I PULLED OFF, TURNED THE CAR OFF AND BACK ON, AND IT STARTED RUNNING AGAIN. I'M LUCKY I WAS NOT REAR ENDED.
