Premature transmission failure with the only option to replace to rectify the issue. Toyota refuses to assist with any portion of the cost even though there are TSB's published noting the ongoing premature transmission failures. Toyota corporate cited routine maintenance not being done at a Toyota dealership as their reasoning for refusal to help and when asked if it was required to only use Toyota dealerships for routine maintenance, they stated that "they can't tell me to ONLY use Toyota but that it was the deciding factor." The cost is close to $10,000 which is catastrophic for most working families. There were no warning lights on the dashboard. Just the distinct high pitch whining sound when accelerating that is noted in the published TSB's. With no warning lights on the dashboard, had I not noticed the whining sound, if "catastrophic failure" would have occurred while driving, innocent lives could have been permanently altered or ended.

Thanks for your service, which is much appreciated. I had a terrifying experience with my 2020 Toyota Hylander Hybrid on XXX. I was traveling slowly on the right Eastbound lane of [XXX] trying to exit onto [XXX], when a car suddey merged from my left, near my front bumper. I put on my brakes with enough room to spare to avoid a collision, however the Hylander overrode my controls, slammed on the brakes with a squeal of my tires, stopped my car completely, started doing a slow, repeating beep, and wouldn't move, though the engine was running. This left my husband and I in an active freeway lane with cars traveling in front of us, to the side of us, and coming up behind us, at 65-70 mph., unable to move our vehicle. I had to turn off the engine off and on again, while in the active freeway lane, to get the Hylander to stop beeping and get it to move again so I could drive off the freeway. I was terrified we'd be rear-ended and possibly be killed, since some automated system in the Hylander would not allow the car to move after it took over and slammed on the brakes. I contacted Stevens Creek Toyota in [XXX] soon afterwards hoping to speak with a service manager about what happened. [XXX] I was told that no one was available when I described my issue to a phone receptionist there. She sent me to a manager's voicemail, where I left a detailed message about what happened. I asked that I be called back as soon as possible, to disable whatever feature caused the car to react in such

My bumper detached from the vehicle on two separate occasions on the freeway. I learned about he bumper recall and brought it to Right Toyota Scottsdale (AZ), my local dealer. Right Toyota failed to follow Toyota's explicit recall protocol to replace the damaged bumper and only installed the upgraded hardware after the bumper had already completely detached. By slapping the hardware on the compromised plastic, they performed an incomplete repair that violates Toyota's legally binding instructions filed with federal regulations. They refused to replace the physically compromised bumper structure during the 23TA12 recall remedy. The dealer actively short-cutting a safety recall. Furthermore, they claimed I had to pay out-of-pocket to replace the damaged splash shield.

We were behind a vehicle that had come to a rolling stop because the vehicle in front of him had hit the person in front of him , we were going about 25 miles per hour and about 2 car lengths from him . I applied the brakes but the vehicle failed to stop . It was as if I did not press the brakes at all. We rearended the person in front of us . The person behind us hit us as well . It was like we were on ice but we were not .

• What component or system failed or malfunctioned, and is it available for inspection upon request? The UA80 8-speed automatic transmission assembly (specifically internal mechanical wear resulting from front carrier assembly bearing degradation/torque converter heat buildup). No, the component and the contaminated transmission fluid are currently being replaced at the dealership. • How was your safety or the safety of others put at risk? The severe mechanical wear and metal-on-metal degradation inside the transmission create an imminent hazard where the vehicle can experience sudden slipping, severe hesitation, or a complete, unexpected loss of motive power while traveling at highway speeds. This loss of acceleration in active traffic creates an immediate risk of a rear-end collision and leaves passengers stranded in an unsafe traffic pattern without warning. • Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. A professional diagnostic inspection confirmed that the transmission fluid was catastrophically low, and the assembly sustained severe internal damage via metal-on-metal contact with metal shavings actively circulating throughout the unit. • Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle has been inspected and diagnosed by a service facility. It has not been inspected by the police or insurance representatives, as no crash has occurred yet. However, th

The steering wheel heating component burned my fingers twice due to a malfunction. I had to attempt to pull over immediately because the steering wheel began smoking and the pain from my finger/hand. Dealership confirmed and fixed issue and the wheel is no longer available to inspect. I was burned while holding the steering wheel and could have steered into another car/pedestrian while driving. I brought it to Toyota and they confirmed a defect and replaced parts of the wheel. I did not bring this up with any other entity. There were no warnings on my dash/anywhere in the vehicle. Smoke appeared after I burned my finger each time. I have attached an image of the smoke, but the only smoke I could capture was limited due to safety issues and not wanting the heating component to be in-use. A video shows it better

My 2020 Toyota Highlander only has 68,826 miles on it. It began making a high-pitched whining sound three months ago. I have taken it to my mechanic and he said the transmission is about to go out. Toyota is not willing to fix it out of good faith/Goodwill since my warranty has ended. My argument is I bought that car thinking it would go 150,000 miles at least.

The contact owns a 2020 Toyota Highlander. The contact stated that while driving, the vehicle stalled and abruptly stopped in traffic at a traffic light. The driver exited the vehicle. The vehicle failed to restart, and the steering wheel was inoperable. The contact was concerned the vehicle might move forward. The check engine warning light was flashing, and the message “High Power Consumption” was displayed. The ignition and steering warning lights were illuminated, and “Low Power” message was displayed. The vehicle was running but failed to move. The contact associated the failure with NHTSA Campaign Number: 20V162000 (Fuel System, Gasoline, Engine) and Special Service Campaign 21TC05. Bystanders nearby attempted to assist the contact. The Emergency Services was contacted, and the Local Police responded to the scene. The insurance company was called and arranged a tow. The vehicle was towed to the local dealer, and the battery was replaced. Additionally, the contact spoke with the service director, management, and the technicians. The manufacturer was contacted by phone, and a case was filed. The failure mileage was approximately 29,296.

My Highlander started making a whining noise while accelerating. Took it to my local dealership and was told I need a new transmission. I have 87,000 miles on it! Total cost = $8,000.

Develop a high-pitched whine, shuddering, or harsh shifting between 25 and 45 mph, which can lead to premature wear or complete failure. Also, On/ Off from no where and stopped in the middle of the road

I was traveling on hwy US1 South about 56-58 mph when I heard what sounded like a gunshot. I immediately slowed down and pulled off the road. As I drove off road on grass/gravel I heard crumbling of glass above on sunroof. The sunroof glass exploded. I called the nonemergency 911 for a police officer to come to the scene. I explained what happened and that there was no rock or large debris. He inspected and suggested I contact my insurance and if they needed a police report it would be in the system.

At 51,000 mile the transmission started making a whining noise. Took it to the dealer and they stated the transmission needs replacement.

My 2020 Toyota Highlander XLE AWD developed a high-pitched whining noise from the drivetrain/transmission area while accelerating. The noise increases under acceleration and stops when the accelerator is released. The noise is not present when the vehicle is in neutral. I brought the vehicle to an authorized Toyota dealership for diagnosis. The dealership confirmed the condition and determined that the transmission requires replacement. The vehicle had only recently exceeded 60,000 miles when the problem was diagnosed. My safety concern is that this appears to be an internal transmission failure occurring at relatively low mileage. Because the transmission is a major drivetrain component necessary to maintain propulsion, I am concerned that continued deterioration could result in loss of propulsion or a more serious transmission failure while the vehicle is being driven. Toyota has reviewed the dealership's diagnosis and has approved supplying a replacement transmission through goodwill assistance. The original transmission has not yet been removed and remains installed in the vehicle. I am reporting this condition because I have identified other complaints involving Toyota Highlanders with similar transmission whining under acceleration and subsequent transmission replacement. I am concerned that this may represent a recurring transmission defect rather than an isolated failure. Because the original transmission is still installed, the vehicle and transmission should current

The transmission started making a whining noise around 69,000 miles that a mechanic said was due to transmission failure. There were no warning lights or messages. I took it to the Toytota dealer who sold it to me new. They inspected it and confirmed that the transmission needed replaced which they did. Online research said these symptoms meant the transmission could fail at any time while driving it which could put passengers and others at risk.

The transmission had a catastrophic failure at 73,000 miles and six years after purchase. There has been a service bulletin issued with known defects on this transmission yet Toyota corporate failed to acknowledge that they installed faulty transmissions in the 2020 Toyota Highlander. The diagnosis was a failed pinion bearing which the dealer diagnosed to replace the transmission at nearly $10,000

Incident: [XXX] Conditions: Clear daylight, dry pavement, normal highway conditions Crash/Injuries: Allstate Claim #[XXX]; several people injured At approximately [XXX], I was driving my 2020 Toyota Highlander Hybrid at about 55 mph in the slow/right lane. The vehicle ahead suddenly made a hard stop. I immediately and forcefully applied the brakes for an emergency stop. My front-seat passenger, [XXX], also saw the danger and yelled for me to stop at the same time. Based on our recollection, approximately five seconds elapsed between his warning and the collision. Despite the rapidly closing distance, the Toyota Pre-Collision System (PCS) did not appear to activate. There was no audible warning/beeping, no flashing red warning, and no “BRAKE!” indicator on the dashboard. This was also observed by [XXX] and [XXX], who was seated in the second row and is particularly attentive to warning signals. The vehicle also did not appear to provide any automatic emergency braking or brake-assist intervention. Despite my immediate and forceful braking, the vehicle did not stop in time and collided with the vehicle ahead, causing significant damage and injuries. The forward-facing sensors and windshield were clean and unobstructed. There were no dashboard warning lights or known system malfunction indicators before the crash. I purchased the Toyota Plus service package after completing the required maintenance during the initial coverage period. All scheduled maintenance and inspections wer

The contact owns a 2020 Toyota Highlander. The contact stated that while driving at an undisclosed speed, the brake pedal was depressed; however, the vehicle failed to stop as intended. The contact stated that the vehicle failed to stop, and the vehicle jerked abnormally. No warning lights were illuminated. The failure was a persistent failure. The vehicle was taken to the dealer. The contact was informed of a software update. The contact was informed that an unknown software update was needed to repair the vehicle. The vehicle was repaired. The contact researched Technical Service Bulletin: 005923, which had a similar failure description. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 15,000.

Coming to a stop or slowing down the vehicle has a spot where it feels like the brakes fail then come back on. Especially if going down a grade. This happens around 15 to 20 mph. Started off a slight moment when you are sure the brakes quit working for just a second. As the vehicle gets older it has brown to be more noticeable.

I was told by oxmoor dealership I had to talk to toyota corporate before I could get my car touched and that I did not need to talk to a lawyer. I called. Prior to the accident, the vehicle had been exhibiting multiple symptoms: an intermittent airbag warning light had illuminated briefly on the dashboard on a few occasions, and the vehicle had begun requiring noticeably longer physical distances to come to a complete stop at traffic signs and lights when not using cruise control. The vehicle was experiencing regular phantom seatbelt warnings—dinging as if a passenger was unbuckled when the seat was completely empty. The phantom seatbelt warnings i didnt think we're a big deal were occurring across multiple seating rows simultaneously in front and back. Directly preceding the crash, while making a turn, the vehicle swerved slightly. When I applied the physical brake pedal, the vehicle did not decelerate normally; instead, it experienced a sudden, abrupt forward acceleration surge into the building. I still haven't gotten my vehicle back or any information on what has been done or when I am getting my car back. I was also charged for an extra day for my rental when I was told to return it on the 16th. I haven't had a rental since then. I keep contacting oxmoor toyota and they said they were waiting on toyota corporate. I haven't had my car for a month. I tried to email. It was returned. My mailbox on my phone has been full of drs and other calls non stop. I texted online on th

I am having fuel pump issues and my VIN was excluded from the recall from Toyota for similar issues. Toyota’s low-pressure fuel pump recall (originally announced Jan 2020, expanded multiple times through Jan 2025) covers vehicles across several model years, where a defective impeller made from inadequate resin material could swell and cause fuel starvation and sudden stalling. Highlander is mentioned as included for selected model years in some recall summaries

We have a 2020 Toyota Highlander with 89K miles that we have owned since it was new. I was informed today to not drive it any long distances from the dealer due to an impending failure of the transmission, creating a large safety issue for me and my family. I understand there are related recalls of the UA80 transmission but none for this particular model; there are countless internet reports of failure. I implore the NHTSA to investigate and protect the motoring public.

I am submitting this complaint regarding a serious braking safety issue with my 2020 Toyota Highlander Hybrid Limited, which currently has approximately 70,000 miles. I brought my vehicle to Victory Toyota of Canton (46352 Michigan Ave, Canton, MI 48188) and reported to Service Manager John Maddison that, at low speeds, the vehicle briefly surges or feels as though it accelerates when I press the brake pedal before it actually begins to slow down. This behavior is alarming and creates the impression that the vehicle is moving forward when I am attempting to stop. This is a serious safety concern that could increase the risk of a crash, particularly in parking lots, stop-and-go traffic, or around pedestrians. The issue has become so concerning that my daughter refuses to drive the vehicle because she no longer feels confident that it will stop properly when she applies the brakes. A driver should never have to question whether a vehicle will respond correctly during normal braking. After researching the problem, I discovered that Toyota has already acknowledged this exact condition by issuing Technical Service Bulletin (TSB) TSB-0059-23. The symptoms described in the TSB closely match the behavior my vehicle is experiencing. I therefore requested that the dealership inspect the vehicle and perform the repair outlined in the bulletin. Instead of addressing what appears to be a known braking-related issue, the dealership informed me that I must first pay a $190 diagnostic fee be

While driving on a 75 MPH highway, the lower bumper cover, windscreen, and interior wheel well components spontaneously detached from the vehicle and got stuck under the car. There were no warming lamps, messages, or other symptoms; the vehicle was driving fine before the detachment. The vehicle has never been in a collision and had no visible damage to the bumper prior to the incident. The detachment was very quick and could have caused an accident, as it was quite physically jarring; additionally, the components got between the vehicle and the highway which caused them to smoke/burn as I tried to quickly slow and pull into the shoulder. A prior recall (#23TB12 / 23TA12) was for a very similar situation. The dealership had allegedly performed the recall fix in March 2025. When I took the vehicle back to the dealership, they said this was independent of the recall. The dealership is unwilling to cover the repair, as they have said that the bumper shows signs of impact. The vehicle bumper has never been impacted. The dealer said there were very minor stress cracks in the paint; when I asked if these could have been from the bumper cover rapidly detaching, they said it was possible but would still not cover the repair.

I pushed the brake and swerved and the car kept going and a greater speed and surged into a house.

Toyota Highlander UA-80 transmission failed prematurely at 63,017 miles (just beyond warranty) due to KNOWN CRITICAL manufacturing defect as per technical advisory T-SB-0160-18 putting me and my family at risk for sudden catastrophic failure on the highway.

The transmission can suddenly fail even at very early mileages. This is almost certainly related to T-SB-0008-21 that has defined a narrow number of transmissions though it appears to affect many more than outlined. This could cause sudden failure while operating the vehicle at any point in time and potentially lead to a crash without much if any warning. Toyota Brand Engagement is denying any assistance due to external service history from a prior owner rather than addressing the failed part outlined in the TSB. Failure reasoning cannot be provided from the dealership as Toyota does not allow the dealer technicians to open the transmission and instead mandate a full replacement.

Transmission stalls in situations where speed is needed. For example when merging into traffic all of a sudden no power then when gear finally engages there a huge thump and feels like being hit from behind.

I know there is a recall for my 2020 Highlander. My VIN isn't listed. The front bumper is coming off and can't be pushed back in.

While driving my navigation system/screen/radio screen goes completely black! Which is dangerous when I’m using gps on the interstate! It does not come back on until I restart the car.

I am submitting this complaint regarding a sudden and unexpected transmission failure in my 2020 Toyota Highlander. The vehicle experienced a major transmission malfunction without any prior warning signs, dashboard warning lights, diagnostic messages, or noticeable drivability issues. The failure occurred suddenly when the vehicle would no longer shift into reverse. When placed in reverse gear, the vehicle does not move. Additionally, when placed in drive, the transmission slips significantly, resulting in a loss of power and unsafe operation. The vehicle is no longer reliable or safe to operate on public roadways. At no time prior to the failure were there any illuminated warning indicators, check engine lights, transmission warnings, abnormal noises, or other symptoms that would have alerted me to an impending transmission problem. The lack of warning created a hazardous situation, as the vehicle's ability to accelerate and maneuver could be compromised without notice. The vehicle has been diagnosed as requiring major transmission repairs or replacement, with estimated repair costs approaching $7,000. Given the severity of the failure, the absence of any warning to the driver, and the significant financial burden associated with the repair, I believe this issue may represent a safety-related defect that warrants investigation. I am concerned that other owners of 2020 Toyota Highlanders may experience similar sudden transmission failures that could result in a loss of vehic

The transmission (the UA80) has been known to have several issues and my transmission has normal driving on it, has had its fluids replaced, and is now experiencing the same issue that others are experiencing.

Air conditioning has leaked after only 60,000 miles, costing me thousands in repairs. This is a recall on other models, but not this one. Mine and my baby’s safety is put at risk by being forced to drive around in the heat of summer without air conditioning. There were no warning lights. It was verified by the dealer, and I have a video of the inspection.

The 8 speed Toyota transmission is defective and my transmission started to whine very loudly. I was told that it could freeze/lock up on me at any time so I had a rebuilt transmission put in my car. I am told Toyota new about this defect.

My transmission failed in my 2020 Toyota Highlander after about 75,000 miles. This is a know issue technical service bulletin # T-SB-0008-21. The dealership acknowledged the known issue and instructed me to reach out to Toyota corporate for goodwill assistance which I did. They are reviewing my case but told me that they will not replace the transmission even thought its a know issue. It will be $10,000 dollars to repair.

The transmission has been making a whining noise since about 75K miles. Had the transmission fluid changed at about 110K miles. Still makes whining noise and now has a rumble occasionally. We took it to the dealer and they said the transmission needs replaced. Over $8k in charges for the repair.

The contact owns a 2020 Toyota Highlander. The contact stated that while driving to the dealer for a service appointment, the vehicle made an abnormally high-pitched sound. The vehicle was diagnosed with a UA80 transmission failure. No further information was available. There was no warning light illuminated. The manufacturer was notified of the failure. The failure mileage was approximately 71,233.

The contact owns a 2020 Toyota Highlander. the contact stated that while driving, the back driver side , the minor child occupant expressed an issue with the seatbelt which began to tighten, The vehicle was stopped to assist the minor child occupant, the seatbelt became tighter and the contact had to go into a store to get scissors to free the minor occupant from the seatbelt. The minor occupant sustained light abrasions from the seatbelt rubbing but no medical treatment was sought. The vehicle was taken to the dealer; however, the vehicle was not diagnosed of repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 59,000.

My 2020 Hylander, which has under 50,000 miles, started to whine with any use of gas pedal/acceleration. None of the warning lights were triggered. My mechanic informed me today it needs a new transmission, and for safety reasons, the car shouldn’t be driven. I’ve been reading how there are known problems with Toyota’s transmissions for my age car—this is negligence on their part—these cars should be recalled and fixed by Toyota.

I took my car in for service and I noticed my car is making a loud whining noise. I asked the mechanic about it and he said my transmission is going out. I found on the web several people complaining about the 8-speed Toyota transmission and how it will stop working shortly. The complaints are numerous and it listed all the of the technical bulletins that Toyota issued and they knew about the problem years ago. I am taking my car to shop to have it fixed or replace. Based upon all my research, I am concerned that the car will stop working and leave me in an unsafe situation. I am not happy that Toyota is selling such a defective product.

Premature transmission failure due to factory defect. All maintenance was done on time and at dealership.

The vehicle recently began making a whining noise when the gas pedal is pressed that is consistent with premature failure of the transmission. I took it to my local dealership and they recommended replacing the transmission and limiting usage of the vehicle to short trips until that is done because the transmission could fail while driving which would result in loss of power to the wheels which could lead to an accident.

Transmission failing/confirmed by dealer at 70k. No slipping, no warning messages, just whining prompted me to have it inspected. There are multiple lawsuits regarding these UA80 transmissions and Toyota is refusing to fix or acknowledge the manufacturing flaw.

This Toyota Highlander make whining sound when I try to speedup, even a little bit. I had a transmission shop checked, and I was informed there is metal pieces in transmission fluid. I am concerned it will break one day on highway while driving.

My 2020 Toyota Highlander hybrid sometimes has a brake slipping or surging sensation when I apply my brakes while stopping. It happens periodically and not every time. I have not taken it to a Toyota service station for this specific reason but I mentioned it while in for a recent oil change. They checked for a recall but didn't find any. I have somewhat gotten accustomed to the issue and have been able to adjust. As I have stated, it doesn't happen every time I apply my brakes. My concern is if I allow someone else to borrow my car or even sell to a new owner. I believe I am the second owner.

The transmission failed. It is available for inspection. Should the transmission have completely failed on the road, it could have lead to an accident. Per the dealership diagnostic: replace transmission and torque converter assembly with applicable seals due to internal transmission failure. It has not been inspected by anyone else. No warning lights. This is a widespread problem in 2017-2020 Toyota Highlanders. Failure frequently happens right after the expiration of the manufacturer warranty and Toyota refuses to pay for it.

The contact owns a 2020 Toyota Highlander. The contact stated while driving at 35 MPH, depressing the accelerator pedal the vehicle to respond as intended and the contact could smell smoke while stopped. A dealer was contacted. The vehicle was taken to a dealer to where the diagnosed the transmission needed to be replaced. The vehicle was repaired, as the shift selector switch was replaced. The manufacturer was notified on the failure and offered to cut five thousand dollars off the cost of repair. The vehicle was not repaired. The approximate failure mileage was 41,800.

Vehicle jerked and then a metal grinding sound. Vehicle would then not even roll in neutral on an incline. Had to be towed to dealer. Transmission has a crack in the case. Need a whole new transmission. I was left on the road. No warning whatsoever.

The transmission failed after 56,000 miles. Based on the research this UA80 transmission has a lot of problems and Toyota has issued TBS and even extended warranty for the previous year models in the past. The transmission failed right after the time allowance for the 5 years 60,000 mile powertrain warranty, but within the mileage.

The Pre-Collision System with Pedestrian Detection is a good thing, but there's a problem. It stops the car too abruptly on the highway, leading to rear-end collisions. When you release the brake pedal, the car remains stationary. To get it moving, you need to press the accelerator pedal. There have been four instances of the Pre-Collision System with Pedestrian Detection being activated in the last 12 months. Two of them ended in rear-end collisions. In the other two cases, there were no cars behind.

Transmission developed a "whine" just before 87,000 miles resulting in the transmission and torque converter needing to be replaced as the transmission was failing.
