2019 Toyota Highlander complaints

I called Toyota as I was concerned it was sluggish and was having trouble excelerating the appointment was given to me 2 weeks out but was told if anything happens to just bring her in. I had to bring her in the week of the appointment on a tow truck as she was not moving. I was told it’s a faulty transmission I asked if it’s covered by my extended warranty and because it’s over by 4 miles it’s not.

The contact owns a 2019 Toyota Highlander equipped with Yokohama Tires, Tire Line: Geolandar HT-G056, Tire Size: 245/60/R18, DOT Number: TCCI2Y889. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed; however the contact noticed that the rear seats were vibrating. The contact also noticed that the rear tires were sliding. The vehicle was taken to the dealer, where the dealer performed a diagnostic test. The dealer inspected the rear suspension and rear springs. The dealer performed an alignment and balanced the tires. The contact was informed that the failure was due to defective rear tires. The contact had purchased the tires from Town Fair Tires. In addition, the contact stated that it was the second time the brand of tires was purchased, and the tires were defective. The manufacturer was not made aware of the failure. The failure mileage was approximately 27,000.

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.

Vehicle stalled on highway. Went into limp mode. Took to Toyota and they said I need a new transmission. The car only has 139k miles. 2019. I purchased it 1 year ago from Toyota with 101k miles.

Whining noise when accelerator is pressed. Potential failed transmission.

My car does have a similar transmission as the one that was recall in Siannas, and Camrys. I have experience the same 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.

Bearly 60 k miles and transmission is going out I got a Toyota because it was reliable did all the required maintenance and Toyota won’t even help

While driving, I began noticing a high-pitched whining or buzzing noise when pressing the accelerator, particularly at low speeds. The sound resembles an electric or remote-control car and rises in pitch with engine RPMs. The noise disappears when I release the gas pedal. A mechanic initially suspected a wheel bearing, but after further inspection, it appears the noise is coming from the transmission or drivetrain. I later discovered that this issue is widespread among 2017–2020 Toyota Highlander models equipped with the UA80E/UA80F 8-speed automatic transmission, which has been associated with internal gear and pump whine. Toyota has issued Customer Support Program POL19-04 and Technical Service Bulletin T-SB-0008-21 addressing similar transmission whine and gear damage, but my vehicle is outside the standard 5-year/60,000-mile warranty and was not included in the extended coverage list, even though the symptoms match exactly. The problem appears to be a design or component defect within the UA80-series transmission, leading to premature wear and potential failure. This can affect drivability, safety during acceleration, and could result in transmission failure without warning.

The contact owns a 2019 Toyota Highlander. The contact stated that while driving at an undisclosed speed, the vehicle lost motive power. The contact was able to pull over to the shoulder of the roadway, where the vehicle failed to restart. The check engine warning light was illuminated. The vehicle was towed to the dealer and diagnosed with head gasket failure, resulting in damage to the engine. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 124,000.

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.

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.

Clog of evaporator box caused water intrusion into vehicle. Water leaked onto Airbag ECU causing malfunction and requiring replacement of Airbag ECU.

Engine revs up to 5k rpm by itself and barely moves forward when stepping on the accelerator. When it does move it’s only up to 40 miles per hour only and the engine will rev up to 5k rpm without moving any faster.

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?

The contact owns a 2019 Toyota Highlander. The contact stated that while driving at an undisclosed speed, there was a high-pitched whining sound coming from the vehicle. In addition, the contact became aware that the transmission was shifting abnormally rough. No warning lights were illuminated. The vehicle was taken to an independent mechanic where it was diagnosed with transmission failure. The contact was advised to take the vehicle to the dealer. The vehicle was taken to the dealer where it was diagnosed with transmission failure. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 90,000. The VIN was unavailable.

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.

,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.

Intermittent EXTREMELY LOUD ear-piercing high pitched noise coming from speakers upon starting the vehicle. The volume of the sounds is extremely high, the loudest noise I've ever heard. The sound lasts about 5 seconds. I am concerned for the safety of our hearing, for my family, including our children. It has not been reproduced at the service center because it is intermittent. I have read online where others with the similar year/make/model experienced it and have varying success by re-subscribing to Toyota SOS Safety connect ($80/year), or replacing the Data Communication Module (DCM). If not uner warranty, this costs thousands of dollars. I have tried re-subscribing to the Safety Connect but it does not work, and the dealer wants me to pay additionally for them to see why this safety feature is not working in my car. There is no warning before this loud sound presents.

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 p

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.

The car only has 73, 000 miles on it and Toyota said it needs a new transmission. The car starting making a "whining" sound on acceleration so we took it into Toyota for diagnostic. We also found out that the Rav 4, Sequoia and Tacoma were all recalled for this same year for transmission issues. Toyota is trying to charge us $10,000 to have the transmission replaced since it is no longer under warranty.

Transmission failure

Transmission whine at 63k miles

I have captain seats in the middle. Driver side seat has 4 bolts that secure it to the vehicle floor. The front two bolts were ready to fall out. Caused a squeak that only my wife could hear due to my hearing impairment. I tightened that bolts and the squeak is gone. Pretty serious issue if only 2 of the 4 bolts holding the seat in place are tight.

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

I have 2019 Toyota Highlander and it has less than 78k miles. A few months ago ago it started barley noticeable wheezing sound and then it got progressively worse. I took it to a the mechanic and he said it was the transmission. It expensive to fix and I saw that a lot if people are complaining about the same problem. I think Toyota should be responsible for replacing the faulty transmissions. My car has been sitting in the driveway because I can’t fix it.

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.

Erratic shifting, dangerous hesitancy and slow starts when pulling into traffic, whining. Took the car to the Toyota Dealer on 08/19/2025, diagnosed as having a failing transmission (detailed service invoice attached).

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.

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.

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

SUV has a pronounced whine coming from the transmission. This started at approximately 85,000 - 90,000 miles and has progressively gotten louder. The car currently has 96,000 miles on it. As I understand it Toyota has issues multiple technical service bulletin about this exact issue covering the 2017-2018 highlander but my 2019 is not covered even though it has the exact same 8 transmission. I have not taken this to the dealer as I understand it would not be covered under the factory power train warranty which is 5 years or 60,000 miles. I've purchased several Toyota vehicles over multiple decades, but with this issue on a vehicle that is not yet 7 years old I am a bit dissapointed and will not be purchasing any more toyota vehicles. Since this issue is specifically related to the powertrain it is most certainly a SAFETY related issue when this transmission fails.

Severe whining from drivetrain car had less then 80,000 when problem started. Dealership has no answer. Car has drivetrain transmission UA80F which has numerous documented issues and has been used in many vehicles which all has same drivetrain problems. This is known problem at Toyota Motor Sales. This issue can cause vehicle transmission to just fail and leave car valueless. The whining has been getting worse every time driven.

There is a potential of a serious accident concerning this car. The engine shuts down completely when you are emerging into traffic. I consider this a death trap. Out dealer in Lima, Oh does not want to fix it. I don't seem to be able to get this problem fixed. I appreciate hearing from you as the problem is getting worse.

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.

Transmission started whining at 90k miles and has failed

The contact owns a 2019 Toyota Highlander. The contact stated that while driving at various speeds, upon depressing the accelerator pedal, there was an abnormal whining sound coming from the vehicle. There was no warning light illuminated. The vehicle was taken to a local dealer, where it was diagnosed, and the contact was informed that the transmission was faulty and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 51,000.

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.

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.

I was nearly in an accident because the vehicle was unable to accelerate quickly due to transmission shift delay.

The contact owns a 2019 Toyota Highlander. The contact stated that on several occasions while driving at various speeds, there was an abnormal whining sound emanating from the front of the vehicle. The vehicle was taken to a dealer where it was diagnosed that the transmission needed to be replaced; however, there was a back log on the part. The manufacturer was notified of the failure. The failure mileage was approximately 70,000.

I had just driven up a steep driveway and made a slightly sharper than 90 degree turn at a very low speed to pull into a home parking spot when the car lunged forward suddenly and slammed into the stone wall of the house at a high speed. The section of this driveway after the turn is only 2.5 car lengths, but the car picked up enough speed to smash the front of the car in. The car was totaled and driver and side curtain airbags all deployed. I do not know why this happened as there is no way I would have hit the gas hard while pulling up to a building to stop. I also would not have slammed on the gas thinking it was the brake since there would have been no reason to slam on the brake when I was only going 5-10 miles per hour max around the tight turn. My shoe was not caught on a pedal, both sandals were still on my feet after the accident. I am not a two footed driver. I feel that it was an accelerator malfunction, as the gas pedal had always been a little strange with a delayed response, but may have also involved the transmission after driving up the steep hill and then returning to a short but flat stretch leading up to the house. I was very bruised up, particularly my shins and ankles. Two months later, I still have some visible bruising. I also had injuries from the seat belt on my chest and what appeared to be a powder burn from the airbags. I was quite traumatized by the sudden acceleration and violence of the crash and not understanding how or why it happened. If some

My car only has just over 70,000 miles and my transmission failed. I get regular maintenance services when needed and never had any prior issues with transmission. I was driving when the transmission failed on me leaving me stuck on the road. I took the car to Toyota service center and was told it needs to be replaced and no further details.

Car started to make whining noise when accelerating, was taken to a car repair shop & it was found that the transmission will need to be replaced with only around 43k miles on the vehicle. Let it be noted that there are many other people on numerous Toyota forums complaining of the same issues.

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

3 of the 4 door lock actuators do not work properly. Some don't lock and some don't unlock. The only door that currently works is the driver's door. If I don't realize that a door did not lock someone can break into my vehicle.

.

Defect with Transmission as hundreds of other people if not, thousands have already stated. Whining noise from Transmission after only 70,000 miles such a big issue that Toyota has a backorder on replacement transmissions.

Check engine light has came on. Code p107b which is what the recall for this vehicle year has but doesnt incude my vin.
