2019 Toyota Highlander: Recalls, Complaints & California Lemon Law

Transmission is whining on speeds between 25-55 mph. Pointing to pre-mature internal failure of components in Transmission.

NHTSA #11740619

The contact owns a 2019 Toyota Highlander. The contact stated while driving 70 MPH, on the highway. the contact notice an abnormal noise coming from the transmission. A dealer was contacted. The vehicle was taken to the dealer where it was diagnosed the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was notified on the failure and they informed him this will not b escalated and offered no further assistance. The approximate failure mileage was 133, 000.

NHTSA #11737673

I am reporting a potential premature transmission failure in my 2019 Toyota Highlander AWD. At approximately 89,000 miles, the vehicle developed a noticeable and persistent whining noise coming from the transmission/drivetrain area. The noise continued despite transmission service and has progressed to the point where the vehicle requires a transmission replacement. I have had the vehicle evaluated by three separate repair facilities, including transmission specialists. All three independently determined that the transmission has failed and requires replacement. Repair estimates range from approximately $7,200 to $12,000. A complete transmission failure at approximately 89,000 miles is unexpected and raises concerns about a possible design or manufacturing defect. A transmission failure while driving could cause loss of power, inability to accelerate, reduced control of the vehicle, or create a dangerous situation while merging, entering traffic, or traveling at highway speeds. The vehicle has been maintained and used normally. I am submitting this complaint because I believe this issue may affect other Toyota Highlander owners and should be investigated for a potential safety-related defect.

Loud whining noises from transmission, repeated unpredictable shifts making pulling out/merging unsafe

NHTSA #11732275

I own a 2019 Highlander at just barely over 55,000 miles. I began hearing a humming noise while accelerating and brought it into Toyota. They told me that bearings are worn in the transmission and I need a new transmission replacement, which will cost $11,569.21. I am shocked Toyota has not issued a recall and corrected this well-known issue. I am disappointed in Toyota, being a loyal customer over the years, if they can't guarantee quality or assist in the issue they know about, I will not trust Toyota again.

NHTSA #11731370

My car all of a sudden has this sudden humming/high pitch sound. I had mechanic checked and he said coming from the transmission. I checked the Toyota forum and there's a widespread issues with their transmission. The issue started with the year 2017, These vehicles are equipped with the UA80F (AWD) and UA80E (FWD) 8-speed automatic transmissions. My 2019 is equipped with the UA80E. Toyota already recognized that they have problems with the transmission but only issued a recall for vehicles 2017-2018. They need to include Toyota highlander 2019.

My Wife drove to work yesterday with no issues. After her shift she stops at the local gas station by her job, she puts the car in park but the car continues to roll forward( as if it was in neutral). Applies the brake and puts the E-brake on(car is now stationary). Puts in some gas, turn car back on, puts in drive and the car is makes a grinding like noise. We get the car towed home, jack it up, drain the fluid. The color of the fluid was darkish but still had a reddish tone to it, very slight sparkle look to it..didn’t see or feel any metal shavings to it.. highly confused on what failed for the transmission to be like that. Haven’t gotten it to the shop yet but a lot of research is showing something internal. No leaks, maintenance has always been serviced on time.

NHTSA #11728320

At 138,000 miles my 2019 Toyota Highlander's transmission failed. I noticed a whining sound when I pushed on the accelerator, so I scheduled a service appointment to have it looked at. The day I brought it into the mechanic it began stalling at stop signs. I was driving my children to school when the vehicle began stalling, fortunately I was able to get it looked at that day. My local mechanic diagnosed it as a failed transmission having to do with something inside the transmission. I called Toyota and they said in order to qualify for support through their service program I needed to have the vehicle diagnosed by at a Toyota dealership. I had the vehicle towed to the dealership, where they too confirmed the transmission had failed due to something inside the transmission, which they diagnosed with a telescope. They quoted me 12K for a new transmission! I had routine maintenance performed throughout the life of the vehicle, primarily at the Toyota Service Center. Just 20 months prior to this happening I had the suggested transmission services completed at the dealership. The only services I had completed outside of the dealership over the last 20 months were regular oil changes and tires. The transmission in my 2019 Highlander is the same failed transmission as the ones in the 2017-2018, which Toyota issued a bulletin on, the same transmission Toyota has received numerous complaints about. The same transmission with hundreds of other customer's have filed incident reports on. The transmission they knew was problematic yet continued to put into new vehicles. I've been a loyal Toyota customer, this is my 5th Toyota. I can't believe that there is nothing Toyota is willing to do to support their customers. I thought Toyota prides itself on being a trusted brand with loyal customers, because they make vehicles that last and take care of them when they don't. I was wrong.

The contact owns a 2019 Toyota Highlander. The contact stated that while attempting to start the vehicle, there was an abnormal grinding sound coming from the vehicle. No warning lights were illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed with transmission failure. The independent mechanic replaced the transmission fluid; however, the failure reoccurred. The vehicle was towed back to the independent mechanic, where it was diagnosed with transmission failure. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The contact was informed that parts were on back order. The manufacturer was made aware of the failure, and a case was filed. The contact was advised to contact the NHTSA Hotline to report the failure. The failure mileage was approximately 128,669.

I have been hearing a high pitched whirling noise. I took it to my dealership and the diagnostic report said it was an internal transmission problem. They said there was no code identified when they ran the diagnostic test, but they could also hear the noise. There were no other symptoms of an issue other than the noise I heard. I have done all scheduled maintenance for this car since I leased, then purchased it in 2019. When I researched the issue further, I found that vehicles from 2019 are known to have been built with faulty transmissions. I did not know this at the time of purchase.

I heard Whining Noise from Drivetrain side under Engine Room first time about a month ago. There is a possibility sure It was generated early that Noise longer than when I heard it. and I visited Toyota Dealership Vacaville CA about this issue, Requested to Diagnosis my Highlander 2019 XLE Gas type Vehicle. Technician said, "FOUND WHINE COMING FROM TRANSAXLE ASSEMBLY INDICATING INTERNAL FAILURE". Service Advisor recommended to replace "UA80E TRANSAXLE ASSEMBLY + TORQUE CONVERTER AND RECHECK". And I found Issue about There is a Document (TSB 0008-21) about this my Highlander 2019 XLE. I did not receive any information or recall or contact from TOYOTA until When I realized it.

I’m concerned that my transmission was defective. My vehicle has 94K miles and was told by dealer I needed a new transaxle. We have never used our vehicle to tow or ever been stuck. It just doesn’t make sense why it would be defective. I was able to locate a Toyota bulletin regarding this.

Transmission began making high pitch whining sound with hard shifting to second gear. Within one year the transmission completely went out and was stuck in third gear.

NHTSA #11724657

My Toyota was just in the shop for 100,000 mile service and investigation of whining noise upon acceleration. Was notified that the transmission needs replaced and will cost over $7500 . Transmissions are supposedly on back order. Upon further investigation, discovered there is a known issue with 2017-2019 Highlander transmissions that Toyota failed to issue a recall and failed to notify owners of these models. Repairs have not been made as transmissions are on backorder due to the magnitude of the issue.

On Sunday, February 1st 2026 during sub-freezing temperatures The vehicle's 8-speed automatic transmission (UA80) experienced a complete mechanical failure while driving. This resulted in a sudden and total loss of vehicle propulsion, requiring the car to be towed. Prior to the failure, the vehicle's AWD system indicator light was illuminated. The failure was diagnosed by Alexandria Toyota on February 3rd of 2026 as a catastrophic internal transmission failure requiring full replacement of the transmission Assembly with cooler (see attached quote). This defect causes an unreasonable safety risk by potentially stranding the vehicle in moving traffic or causing a crash due to unexpected loss of power.

NHTSA #11715481

Vehicle experienced sudden loss of power and severe hesitation from a stop. Acceleration is extremely weak from approximately 0–20 mph, then returns to normal once moving. Traction control system automatically disables itself and check engine light illuminates. Vehicle feels unsafe when pulling into traffic or intersections due to delayed acceleration. Diagnostic trouble codes retrieved: P0740 (Torque Converter Clutch Actuator Stuck On), P0745 (Pressure Control Solenoid A Stuck Off), and P2713 (Pressure Control Solenoid D Stuck Off). Dealer recommended full transmission replacement costing over $11,000 at only 79,000 miles. Dealer stated this failure is common on this model. Similar failures have been reported by other owners of Toyota vehicles equipped with the UA80 8-speed automatic transmission. No recall currently exists for this issue. This condition presents a safety concern due to delayed acceleration when entering traffic and loss of traction control functionality. Vehicle is being driven minimally until repaired.

The transmission is whining and is going out it is shifting hard now.

NHTSA #11713807

My 2019 Toyota Highlander started making a whining noise from 0mph to 40mph-- and at times would shift hard. I took it to first mechanic who stated it was definitely a transmission issue. I took it to a transmission shop who also confirmed it was a transmission issue. I had vehicle towed to Toyota Dealer who performed a Multipoint Inspection and vehicle was placed on a scanner. The codes indicated "internal failure" on transmission and quoted me $10,500 to remove and replace. Parts are backordered for 8 weeks+. Current transmission is only at 63,000 miles and I am the 2nd owner.

NHTSA #11726685

Transmission failed catastrophically at 133,000 miles while vehicle was in operation at a busy intersection. Vehicle became immobilized and unable to move. Unable to safely exit vehicle due to traffic. Stranded for 60-90 minutes with multiple vehicles nearly striking the disabled vehicle, creating a serious safety hazard. Police were called but failed to show up. Prior to failure: Vehicle exhibited loud whining noise during initial startup that would sometimes lessen or stop. This symptom appeared sometime within the last 1,000 miles of operation. Toyota dealer service at 132k miles noted transmission fluid was "Ok" during routine maintenance. At 133k miles transmission failed catastrophically. Independent transmission service center reports burnt-smelling transmission fluid indicating severe thermal damage and transmission failure. Problem confirmed by two independent service centers. Transmission is available for inspection upon request. Vehicle is not drivable.

Ua80 transmission failed.

NHTSA #11720025

Transmission began to manifest gear shifting issues. Took to mechanic shop to have diagnosed and found premature wear. The recommendation was to replace this transmission. However there are no factory replacements for this transmission and the only alternative is a used transmission replacement. Parts can't be sourced for even a rebuild. This vehicle has 96k miles on it. In review of recommended, routine services for this vehicle, transmission service is not recommended due to being a "sealed" transmission. Apparently this is a known issue as documented by Toyota under TSB "CSP ZJC". In this particular situation there have not been any warning lights. Replacement quote for a used transmission was $15,000 on 01/12/2025.

Good Morning, I purchased a 2019 Toyota Highlander at a Toyota dealership and the transmission has died at 68,000. It died while driving in heavy traffic with my kids in the car. Toyota has completed an inspection of the transmission and determined that it needed to be replaced. They also said that because the transmissions are in back order due to all of the failures, I would have to wait 45-60 days to get a remanufactured transmission. I've also heard that they are replacing these transmissions with the same ones that are failing and only offering a 1 year warranty. Ive already spoke with Toyota Brand engagement and they told me that there was nothing that they could do.

NHTSA #11710875

Transmission failure. Unexpectedly failed while driving. Failure to accelerate before total failure. Repaired with used transmission since new ones are unavailable. Called Toyota to report the failure. No acknowledgement of any failure mechanism.

NHTSA #11718334

We began to hear a whine coming from the front of our 2019 Highlander. The tone of the whine got higher as we picked up speed. We went immediately for a preliminary review at the dealer who indicated that it was a known transmission problem in several model years, and the whine would only become more pronounced. We further understood that the very same transmission in our 2019 Highlander has been covered by a recall in years just prior and after 2019, but not for our particular VIN. Nevertheless, it is obvious to even the Toyota dealer mechanic that it is the same issue. The car has been carefully used and maintained since purchasing it new--it only has approximately 74,000. We expect our transmission fix or replacement to be covered.

NHTSA #11708838

While driving, my vehicle experienced a sudden transmission failure. The vehicle began to lose power and was unable to shift properly, making it difficult and unsafe to continue driving. I had the vehicle inspected and the transmission is currently being rebuilt. The mechanic performing the rebuild has stated that the failure was caused by a faulty build and a manufacturer defect, not normal wear and tear. I am currently awaiting written documentation from the mechanic confirming this, which will be submitted once received.

NHTSA #11716528

The transmission failed while going up a steep hill the car lost power and shut off. Could have caused seriously property and body damage if traffic or people were around. Luckily no accident happened but could certainly cause an accident if the circumstances are different. Please make an official complain so this could be fully investigated.

2019 Toyota Highlander with approx 178000 miles, UA80E transmission sudden failure while traveling approximately 30 mph, on city street. Manually pushed vehicle to safety away from traffic and unto a parking lot. That same evening drove vehicle about 20 feet to a more secure parking spot. VEHICLE HAS NOT BEEN MOVED SINCE 12/15/25. No leaks, no spills etc EXTREMELY DANGEROUS.

With under 80,000 miles, my 2019 Toyota Highlander XLE needed a full transmission replacement. Noticed some rough gear changes for about 2-weeks (mostly changing from Park to Drive), then on my drive home from work, the RPM spiked high and all the sensor lights came on (AWD, Check Engine, etc). I drove the rest of the way with hazard lights in limp-mode. Took my car into a Toyota dealer service center (Kenosha WI), they did not make any repairs - just disabled the sensor lights and did a test drive - ended up keeping a 2nd day and replaced transmission fluid since they were seeing oddities with shifting. Within 1 week, the same thing happened. This time, I could hardly make it above 20 mph, basically no acceleration. Received 2 quotes from independent transmission specialists / repair shops - both confirmed I needed a new transmission. They said the car is unsafe to drive until it is replaced. This was right near my 6-year 100,000 warranty. Perhaps a few months beyond 6 years. Toyota opted not to make any repairs / improvements. Left the car in unsafe condition for me and my kids. Toyota then quoted $16,346 for a new transmission. Other quotes I received were $10,000 LESS than Toyota, using new Toyota parts. Seemed like price gauging to me.

On Monday December 15, 2025 our transmission failed as we began to drive up a small grade in between two sets of railroad tracks at the intersection of Cary, Ushers and Coons Crossing Road in the county of Saratoga, NY. If it had failed on one of the two sets of tracks it may have endangered us. On December 17, 2025 Northway Toyota in Latham, NY diagnosed the transmission failure at their dealership. I had attached the appropriate documents. The only warning for failure was a whining sound a few days leading up to the failure, but we thought it was a normal sound from the engine which we have subsequently learned was a sign of a failing transmission as we investigated prior complaints from others.

NHTSA #11712359

My wife was driving here Highlander at freeway speeds when the vehicle started slowing and would not respond to the throttle. No warnings lights. It would drive but not accelerate to any reasonable speed. She pulled off the freeway and found a parking lot to test, restart car, etc. Again, no warning lights. Once in park, the vehicle would not shift into gear but only revved. The vehicle could not be driven and towed to a Toyota dealer and after a number of tests, it was diagnosed as a blown transmission. It was replaced at great expense. I do not know what the dealer did with the transmission but it was not tested. The safety issue is the sudden and expected loss of power/drive train on a freeway. The vehicle has been well maintained. At 100K, plugs and transmission fluid were replaced. Although the vehicle had around 130K miles, the transmission should not have failed in my opinion.

My 2019 Toyota Highlander XLE V6 developed a serious transmission-related safety problem that ultimately resulted in a sudden loss of propulsion while driving. For some time before the failure, I had noticed an unusual startup noise during cold starts and mentioned this concern during routine service visits at an authorized Toyota dealership. I was advised that the condition was normal. Prior to the major failure, the vehicle otherwise remained drivable. On December 2, 2025, the vehicle underwent scheduled maintenance at an authorized Toyota dealership, including a transmission fluid service. Within the following days, during cold weather conditions (approximately 35°F), the vehicle began exhibiting transmission shudder, RPM flare, harsh torque converter engagement, and illuminated both the Check Engine and Traction Control warning lights. I immediately returned the vehicle to the servicing dealership and reported that these symptoms had appeared following the maintenance visit. After inspection, I was informed that the torque converter clutch actuator had failed and that the transmission would require replacement or rebuilding. The vehicle was released to me, and I was not advised that it was unsafe to drive or that it should not be operated. On the morning of December 11, 2025, while driving home from work in approximately 31°F temperatures, the vehicle suddenly lost propulsion. The engine RPM increased, but the vehicle would not move under its own power. I narrowly avoided being rear-ended by a truck traveling behind me. I believe this created a significant risk of a serious collision. The vehicle was towed and remained out of service for approximately two months because replacement transmissions were difficult to obtain. The transmission was ultimately replaced with a used transmission assembly at a total repair cost of approximately $7,220. After the transmission replacement, the unusual startup noise that I had previously reported completely disappeared,

The vehicle is relatively new 2019 and mileage is low 45000 car was humming for no reason for a day or two and its well maintained, today at busy thoroughfare it stalled at intersection of ave u and another street and was behaving erratically due to know manufacture defect of Toyota Transmission UA80E/F that causes sudden stall and thank god have. I stalled on highway it would have been a catastrophe. I want NHTSA to acknowledge danger this poses to drivers if suden loss of power occurs suddenly hoping for a solution to this dangerous manufacture defect.

premature failure of UA80F transmission with 80,000 miles on vehicle which has been regularly serviced and maintained. Failure symptoms demonstrated match documented cases exactly resulting in the ultimate and complete failure of the transmission resulting in the vehicle being towed in to the dealer for a repair. Repair bill upwards of $10,000 however being told parts not available leaving me with a 40k vehicle that is unable to be repaired.

NHTSA #11705400

My vehicle was taken into Toyota dealership for diagnostics after experiencing a whine noise from transmission after driving. Toyota confirmed that I will need a new transmission. After researching I found that there is a defect in the transmissions for my specific type. It has been reported for years but Toyota has not addressed. Since it is a transmission failure this could lead to a breakdown while driving on highways and could risk my safety and other drivers. The estimated repair cost are currently above $8K.

NHTSA #11701630

Transmission failure. Vehicle is at this time still operational however the transmission has developed the ever so common whining sound and sluggish shifting. Upon fluid inspection metal filings can be seen and replacement has been recommended by repair shop. The whining has been evident for some time but after investigating this issue decided to have inspected. This inspection was just completed on 11/14/25

Our 2019 Toyota Highlanders transmission is gone. The car has 83,000 miles. I have been researching online and found out that Toyota is very much aware of the problem. They're refusing to help me. They're basing it on our VIN#. No recalls. I just want them to acknowledge that the issue needs to be addressed NOW.

Owners of 2017–2022 Toyota Highlanders, 2017–2020 Siennas, and 2018–2020 Camrys are experiencing serious transmission issues—including high-pitched whining, erratic shifting, clunks, hesitation, and premature failure. These vehicles are equipped with the UA80F (AWD) and UA80E (FWD) 8-speed automatic transmissions. Toyota quietly acknowledged the problem in Technical Service Bulletins T-SB-0160-18, T-SB-0008-21, and a limited Customer Support Program (CSP ZJC)—but only offered coverage to a narrow group of VINs. Thousands of other affected vehicles were left out, even though they show the same exact symptoms.

I am writing to you as a deeply loyal Toyota customer who is facing a distressing and financially significant situation with my 2019 Toyota Highlander. Our family has been committed Toyota owners for several decades. Over the years, we have owned a Toyota Corolla, Camry, and multiple Highlanders — and we currently drive two Toyota vehicles. We have consistently chosen Toyota over other brands because of the trust we place in your engineering, reliability, and the value Toyota stands behind. We even replaced all of our Honda vehicles with Toyotas because of that trust. We purchased our 2019 Toyota Highlander during the COVID-19 pandemic, paying above market value because we believed in the Toyota brand and its long-standing reputation for durability. We have never regretted that decision — until now. At approximately 95,000 miles, our Highlander began exhibiting a high-pitched humming noise and gear slippage. We brought the vehicle to our Toyota dealership, who diagnosed the issue as a complete transmission failure. The repair estimate provided was $17,000. We were also informed that this repair would not be covered under any existing warranty. We are not only shocked by the severity and cost of this failure on a well-maintained, 7-year-old vehicle — we are also deeply concerned by what we discovered in our research. There appear to be hundreds of complaints from other Toyota Highlander owners reporting the exact same transmission issue, across the same model years, suggesting this may be a widespread and systemic defect rather than an isolated incident. Given this context, we respectfully ask Toyota to consider the following: 1. A goodwill warranty exception or partial/full coverage of the transmission repair cost, in recognition of our long-standing loyalty and the apparent prevalence of this issue across multiple vehicles. 2. An acknowledgment of the reported pattern of transmission failures in the 2019 Highlander, and whether Toyota is investigating or plan

2019 Toyota Highlander XLE with 94,000 miles. This past Friday, the transmission started slipping...slow to move while pushing the gas pedal. After about 20 minutes, was slipping less. Pulled code P2757 off of OBD. By Monday, the car wouldn't move despite revving up to 3500-4000 rpm. Reverse would work, but not first gear. Called AAA and had it towed to a shop. Shop didn't give me codes, but said there were several. They reported that the transmission needed to be replaced or rebuilt.

Transmission failed at 143,000 miles. Initially vehicle lost acceleration and would not go over 60mph. Then vehicle would not go into drive, and instead rolled backwards. Vehicle was towed to dealership where they provided a report saying it needed a new transmission that would cost $9,000. No warning lights were ever present on vehicle, it just stopped operating.

NHTSA #11698302

Transmission. Taken to dealership immediately. Notified that the transmission was going to have to be replaced. Notified there were no transmissions available or re-manufactured transmissions available, that our warranty was up 3 months prior to this date and we would have to spend in the range of $8500-$12,200 to get it fixed when a transmission was available. Warranty company did decide to cover some of the cost, but we were out of pocket almost $4000. This problem did not gradually appear, it was instant on the date the incident occurred. Filed a complaint with Toyota, they will not take responsibility and reimburse us any money. This should not be a problem with a Toyota with this many miles on it and they should take responsibility.

The contact owns a 2019 Toyota Highlander. The contact stated that while driving 40 MPH uphill and depressing the accelerator pedal, the contact heard a grinding sound and smelled an odor coming from the front of the vehicle. A dealer was contacted. The vehicle was towed to a dealer, where it was diagnosed and determined that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure and opened a case. The approximate failure mileage was 160,000.

My car was having trouble shifting gears and then every single light came on indicating a big problem. The check engine light came on, it said ABS off and went through a bunch of different things saying they all turned off and would barely roll at 2mph. I took it in and it needs a full transmission replacement at barely 73,000 miles. Upon looking into it, I saw online that this is a common issue that Toyota still has not issued an official recall for despite it being a very common issue. It’s a 2019 Toyota Highlander XLE and should not be having these issues this early on.

The contact owns a 2019 Toyota Highlander. The contact stated that while driving approximately 35 MPH, there was an abnormal whining sound coming from the vehicle. There was no warning light illuminated. The contact previously owned a 2017 Toyota Highlander and heard the same whining sound coming from the transmission. The contact stated that when the 2017 Toyota Highlander was taken to the dealer where the vehicle was purchased, the contact was offered a trade of the 2017 Toyota Highlander for the 2019 Toyota Highlander. Following the failure of the 2019 Highlander, the vehicle was taken to two different dealers to be diagnosed. The first dealer had not diagnosed the vehicle but stated that the vehicle was operating normally. The vehicle was taken to another dealer, who diagnosed the vehicle and determined that the transmission needed to be replaced. The vehicle was not repaired. The contact researched the failure online and determined that the 2017 Highlander and the 2019 Highlander had the same model transmission, UA80F - CVT transmission. The manufacturer was informed of the failure and informed the contact that the vehicle was no longer under warranty. The failure mileage was approximately 133,000.

The 2019 hylander started whining when pressing the gas pedal. I had it checked out and found that it needs a new transmission but it is so prevalent of an issue with this vehicle that the transmission is on severe back order. Every complaint on the department of transportation website about this vehicle are about this issue save a handful. We should not be liable to pay for this repair nor for a rental car for months while we wait for the parts.

Per my mechanic (fyi: 56k miles on vehicle): I test drove the vehicle and can hear a noticeable whine type noise when accelerating the noise goes away when getting off throttle. I put it on lift and the noise is coming from the transmission pump and sounds like cavitation. I checked the fluid level and it was overfull, very dark and has some very fine metal debris in the fluid. Something is coming apart inside the transmission has caused a catastrophic failure. The transmission will need replaced. I called Toyota to check availability and these transmission are on a restricted order. The dealer would need to call corporate Toyota to see what is needed to even order one. Usually a restricted order means they are on the edge of a back-order or having problems with the part and are working on a resolution or update. I did not see any recalls, service campaigns, or technical service bulletins for this transmission, but it sounds like the 2017-2021 V6 AWD UA80F transmissions are having issues. It is a long shot, but given the low mileage, you could try contacting Toyota to see if there is anything they can do for you. I know the factory warranty is 60 months or 60,000 miles on the powertrain. You are out on the time, but if they are having a known issue, then maybe they will help you.

NHTSA #11707790

128,000 Miles and the transmission is making a whining sound that progressively gets worse with acceleration. Also has occasional erratic shift associated with no throttle response. Sound is obnoxiously loud on the freeway deeming it almost undriveable.

NHTSA #11712854

A couple of days ago, I started hearing a faint whining noise coming from my vehicle when I pressed on the gas pedal. When I brought my vehicle into the dealership today for my 100,000 mile service, I advised them of such. After raising the concern, I was told that there was an issue with my car's transmission and that it was not covered by the warranty as the warranty for that part ended at 75,000 miles. After looking up this issue and the cost to replace, I learned that this transmission issue is a prevalent issue with 2017-2021 highlanders with over 60,000 miles. This issue is so prevalent that there is a huge backorder for parts needed to fix this specific issue. I have owned multiple Toyotas because of their reliability. I had a 4 runner that I used past 225,000 miles with no issues. The fact that I'm having an issue with a transmission issue with a vehicle with less than 100,000 miles on it that I always service every 5,000 miles at the Toyota dealership I bought the vehicle at is huge red flag and is making me reconsider my allegiance to the Toyota brand. The dealer has quoted me a price of $7,500 to fix the issue. I believe that Toyota should make this right as it is clear that this is a known and prevalent issue with the highlanders. In fact, I'm surprised given the number of people complaining online that it is not the subject of a recall. As a lawyer, this sounds like an issue ripe for a class action. That being said, I am hoping that Toyota will work with me and pay for the repair and/or furnish me with a new car credit.

NHTSA #11690601

,At approx. 76,000 miles, we begin to hear a whine with acceleration. We also begin experiencing slight hesitation? It was diagnosed at The Williams Toyota Dealership in Big Flats New York 9/22/25. The dealership indicated the final drive gear bearing is starting to fail and we need to replace the transmission at the cost of $7472.00 plus tax. We are aware of the several class action lawsuits that have been filed against Toyota regarding the UA80E/F 8-speed automatic transmissions. The litigation covers multiple Toyota models 2017 model year and onward including the Highlander.

Transmission failure. Car will not drive or reverse. Engine turns on. I’m told that transmissions are on back order with no ETA.

NHTSA #11687114

A wining started on my 2019 Toyota highlander. I took to mechanic and they confirmed it was transmission. There was no warning.

NHTSA #11732308

Transmission went out at 93,000 miles. Toyota dealer confirmed the car needs a new transmission and wants me to pay $7500 for it. This seems ridiculous for these to go out the early. I follow all the regular maintenance schedules

NHTSA #11685424

The contact owns a 2019 Toyota Highlander. The contact stated that while stopped at a traffic light, the vehicle failed to accelerate as intended while depressing the accelerator pedal. No warning lights were illuminated. A passerby helped push the vehicle to the side of the road. The vehicle was towed to the dealer, where the vehicle was inspected, and the contact was informed that the transmission had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 143,335.

NHTSA #11685358

Car Manufactured in April 2019. Transmission failure at 113,000 miles. Before failure, the transmission had a whine and lag when accelerating from a full stop, creating an unsafe situation when pulling into traffic. The cost to repair is over $9,000, and the part is on backorder for several months. The NHSTA facilitated a voluntary service bulletin with Toyota that extended the warranty for the Highlander model years 2017 to 2018 for issues related to the UA80F transmission. The service bulletin should extend to the 2019 model year, as the issues are the same and the transmission model is the same, and possibly for models built early in 2019, which likely have transmissions built or component parts from 2018.

NHTSA #11686294

The transmission was checked by Toyota at 55,000 miles for whining sound. Technician advised that it is a normal sound for that type of transmission and it is ok. The sound continued to get louder , so we took it to 2 independant garages and they advised that the noise is the transmision going bad. At 64,000 miles we took it back to the same dealer to tell them we thought it was the transmission. The technician road with us and said he thought it was the brakes or something else. After returning from the test drive with the technician, 3 technicinians looked at it and agreed that the transmission is bad and should be replaced. The factory warranty expired at 60,000 miles and Toyota is not honoring that we took it to them for the same problem prior to warranty expiration. They are advsising that it has not completely failed yet, so it's not a problem. I do not want to drive my vehicle for any distance or at highway speeds for fear of failure in a dangerous area or stranded during bad weather.

NHTSA #11690151

At approximately 64,607 miles, my 2019 Toyota Highlander experienced a complete transmission failure. The vehicle had. been properly maintained. There were no warning lights prior to the failure. The transmission began making a high-pitched whining noise, followed by difficulty shifting. Research shows that many other 2019 Highlander owners have reported the same issue, often described as the "death whine," occurring between 50,000-100,000 miles. These failures appear related to the UA80 8 -speed automatic transmission, which has already been the subject of service programs in earlier 2017-2018 Toyota vehicles. Transmission replacement cost range from $7,000 - $10,000, with parts frequently on backorder. A major drivetrain failure at such low milage, raises significant safety concerns, and appears to be a recurring defect that warrants investigation.

NHTSA #11682832

The transmission has exhibited signs of premature failure due to an internal component defect. The only indication was a whining noise when accelerating. This was first noticed around July 2025 when the car had about 78,000 miles on it. The car was later inspected by the Toyota dealer on 08/20/2025 with 79,253 miles on it. The Toyota dealer determined that "the noise being heard was the transmission becoming faulty" and prescribed replacing the transmission "as soon as possible." This is a safety concern if the transmission suddenly fails while driving, but I am not going to wait for that to happen before replacing it.

NHTSA #11685258

Transmission started whining at 90k miles and has failed

NHTSA #11682313

At around 107,000 miles, we started hearing griding/whining noises from the engine compartment. After multiple inspections from 3 different auto shops a Toyota dealership confirmed the transmission and transfer case had failed and needed to be completely replaced. There were NO warning lamps, messages or other symptoms besides the griding/whinig noise prior to the failure. After the Toyota dealership diagnosed the issue, we stopped using the vehicle until Toyota could make the necessary repairs for the vehicle to be safely driven. The Toyota dealership made the necessary repairs that we paid for on 10/28/25. We are aware that this is a known defect by Toyota on the UA80 Transmission and Technical Service Bulletins have been released. We demand a recall and our out of pocket repair cost money back of $12,623.31.

NHTSA #11704853

8/15: I was informed that the had a transmission failure requiring full replacement. The highlander is a 2019 SE with a UA80 transmission which we have now discovered has multiple complaints against it. Our car only has 108,000 miles and has been maintained with all required maintenance a full transmission service.

NHTSA #11704598

I’m reporting a drivetrain and engine performance issue affecting my 2019 Toyota Highlander, which I believe is related to Toyota's T-SB-0160-18, T-SB-0008-21, and Customer Support Program ZJC (CSP ZJC). My vehicle is exhibiting the same symptoms like: 1. Intermittent engine misfires (no consistent CEL, but noticeable during driving) 2. Hesitation and shuddering during light or moderate acceleration 3. Unintended surging/lunging — the vehicle will randomly jerk forward without throttle input 4. Whining noise under acceleration, which appears to come from the engine bay These symptoms negatively affect vehicle control and driver confidence, especially when merging, passing, or driving in traffic. The behavior is unpredictable and poses a potential safety hazard. After researching, I found that Toyota issued T-SB-0160-18 and T-SB-0008-21 for this engine, acknowledging similar performance issues due to valve train irregularities and ECM programming. Toyota also released Customer Support Program ZJC, offering limited support to some VINs. However, despite my vehicle showing the same symptoms, it is not included in the CSP, and Toyota has not offered assistance without out-of-pocket costs. This issue appears to be more widespread than Toyota’s internal VIN list suggests. Many Highlander owners have reported the same issues online, and I believe Toyota should take responsibility for correcting these performance defects under a recall, not a limited CSP. I respectfully request that the NHTSA investigate the scope and validity of Toyota's CSP ZJC and TSBs related to the 2GR-FKS engine and push Toyota to expand CSP ZJC or issue a formal recall to cover all affected vehicles based on symptoms, not just VINs

Hi. I have a Toyota 2019 Highlander EXL. My problems is the transmission started to have the small whining noise every time I accelerates and I it's happened over 18 months ago and I didn't know that is the issues until I brought it to the Toyota Dealer for 75k maintenance. The Dealer has told me that the noise was abnormal and it's from the transmission and it's will cost me $13 K to replace with a new one. I believe in Toyota quality but now I will have to really think about it again for the next purchase ?. I don't understand why Toyota has known this issues because of many reported but never intend to fixed it. I'm not so happy with this . Please ask ToyoTa Corp to answer and do take the responsibility before someone is getting hurds Thanks Tom le

NHTSA #11660678

Transmission failed while driving down the highway almost causing an incident. These transmissions are very unsafe and should be recalled. Toyota refuses to take responsibility for this year Highlander although it is the same 80ua transmission that was recalled in the 2017 and 2018. While Toyota has said this problem has been remedied in the later years it is very false. Please do an investigation on this before people get hurt from accidents if they haven’t already.

NHTSA #11659135

At approximately 85K miles my 2019 Highlander began to exhibit a high pitched “whirring” sound upon accelerating. The noise stops once you take your foot off the gas. I brought the vehicle to my local Toyota dealership to investigate the noise. They concluded that it is the transmission and I would need to replace the entire transmission. There are no warning lights or other indications aside from the sound. Transmission fluid is clear of any shavings or other indicators of an issue. Toyota service stated they could not tell me if or when the transmission might fail, just that it should be replaced. There are multiple reports of similar occurrences on online Toyota forums. There are also recalls for the exact same sound for the 2018 Highlander. I opened a case with Toyota customer service and was told there was nothing they could do to assist.

When accelerating, started hearing a whining noise. Took to mechanic, said it was the transmission. Called Toyota and they had us bring it in for diagnostics. Also said we needed a new transmission. Quoted at over 13K - could fail at any time. This should not be happening in a 2019 vehicle and seems to be a known issue that Toyota is not doing anything to address.

The AC stopped working on our 2019 Highlander. The vehicle has very little corrosion underneath or in the engine bay, yet the rear AC lines have corroded at a location where two different types of metal contact each other. This has been happening with many highlanders after 5 years, and the cost to replace is expensive.

The contact owns a 2019 Toyota Highlander. The contact stated that while driving on several occasions at various speeds, the contact heard abnormal buzzing sounds coming from underneath the vehicle. The vehicle was taken to a dealer; however, the failure could not able to be replicated. The contact stated that a day or two days later, while stopped at an intersection, and attempting to accelerate, the vehicle failed to accelerate as intended. There were no warning lights illuminated. The vehicle was pulled over to the side of the road and restarted; however, the failure persisted. The vehicle was towed to a dealer, where it was diagnosed and determined that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 59,000.

Started noticing a whining noise when accelerating. This appears to be drive shaft/transmission issue. Was quoted 7k to remove and replace. This should be an active recall for this issue what is Toyota doing?

NHTSA #11692580

Our 2019 Toyota Highlander currently has 54,605 miles. In August 2025, when the vehicle had 50,236 miles, we brought it to the Toyota dealership to address a whining noise coming from the transmission. At that time, the vehicle was still under the manufacturer’s warranty. The dealership performed a transmission service during that visit. Within the following weeks, however, the whining noise returned, and the vehicle began experiencing hard and delayed shifting. Our children and grandchildren have recently moved to Washington, and we had planned to drive there to visit them. Unfortunately, we are now reluctant to drive the vehicle due to safety concerns, as we have been advised that the transmission may be failing. The dealership has now recommended a full transmission replacement. Because the original concern was reported while the vehicle was still under warranty, we believe the issue should have been properly diagnosed and resolved at that time. However, the problem was not addressed, and the vehicle is now outside the warranty period, with Toyota declining to cover the cost of the replacement transmission. Given that the problem was first reported while the vehicle was under warranty, we are requesting that Toyota reconsider covering the transmission repair or replacement.
