The component that failed was the transmission. My safety was at risk because I was going uphill and the engine surged then the transmission seized, almost causing a rear-end incident with my family in the car. The dealer confirmed that the transmission has failed. No incident happened so only the dealer needs to be involved at this time. There were no warning lamps indicating to me that the transmission failed. Upon discovering that the transmission was not downshifting (based on the engine not downshifting uphill), I put the car into manual mode to determine if I could manually shift down or not, it would not downshift. Attempting to downshift to gears 4, 3, 2, or 1 was not possible, the lowest gear was gear 5 and the engine had no torque to get up the hill that it was seized on. The 2019 Toyota Highlander was serviced for the automatic transmission fluid at 100K miles and failed at about 120,450 miles.

The transmission has been making a whining noise for a little while now. After having it diagnosed by Toyota, the entire transmission has to be replaced. According to multiple reports on the internet, the 8 speed transmission in the 2017 to 2026 model will fail prematurely do to defective components. Toyota has even replaced multiple model year transmissions under a specific TSB but has not included later model years. I know have to spend $10,500 to replace the transmission at Toyota.

Transmission is failing and accelerating past 40mpg produces very loud sound that seems it could break any moment. It is available for inspection. Safety is compromised as it could experience failure and abruptly lose ability to accelerate. Problem has been confirmed by independent service center who has also contacted Toyota Dealership regarding possible replacement and about the issue at hand. Has not yet been inspected by manufacturer, police, or insurance rep. No warnings and it first occurred June 2026 of this year. Contacted Toyota Brand Engagement Center and denied any assistance.

I purchased this Toyota Highlander two years ago, and I am extremely disappointed and frustrated that it now requires a transmission replacement costing approximately $10,000. I understand that vehicles can require maintenance and repairs, but a major mechanical failure of this magnitude is a significant financial burden. I have reached out multiple times seeking assistance and a reasonable resolution, but I have been unable to get anyone to take responsibility or offer meaningful help. I should not be left to shoulder such an enormous expense without a fair review of the circumstances. I am filing this complaint because I believe this matter deserves further investigation and I am requesting assistance in reaching a fair resolution.

I was on interstate 75 and the transmission went out. I had to be towed home (over 100 miles). I pulled into a rest area and when I went to leave, I pulled out and the engine RPM's went real high and the car would not go over 20 MPH. I was in the way of semi-trucks as I tried to get back to a parking spot at the rest area. Thankfully This did not happen while driving. After getting to the repair shop they could not even steer the car. I want Toyota to help me with the cost of the repair. This car only has 85,000 miles on it and it is a 2019. It should be good for at least 200,000 miles. I feel very fortunate that I was not actually on the highway when this happened.

My husband was driving my car out of town, and while driving approximately 70 mph, my car stopped going. When he pressed the gas pedal, the engine revved, but did not move forward. He had to coast down the interstate and pull over on the side of the road. He said he almost got tear ended by a semi-truck. I called roadside assistance through my insurance company and it took them 2.5 hours to get to us. We had to have it towed about 70 miles to a shop and pay $184.00. The body shop we towed it to said it is the transmission. He said he knew it to be a common issue with 2019 Toyota Highlanders. I looked it up online and found several instances of similar stories. There was no warning.

I started hearing a faint sound and initially thought it was odd, but certainly sounded different and could not really tell where it was coming from. Upon taking it to the dealer for diagnosis, I learned that the transmission will need full replacement. I also took it to an independent shop to get a second opinion and much to my dismay, they confirmed the same.

The vehicle began making a whining noise several months ago. After doing some research this vehicle has the UA80 transaxle that has a known defect that produces the whining noise and eventual damage. There are other years of this vehicle that are subject to a recall/repair for this same transaxle issue, but not for the 2019 even though it's the same transaxle with the same assembly defect. This is a known issue by the manufacturer. The end result without repair will be a transaxle failure while in gear / loss of propulsion. This vehicle has not been taken to a dealer for inspection yet. If a request for inspection is made, the vehicle can be made available. Also, no warning lamps or messages gave any early indication of an issue, only a whining noise was noticed.

I am filing this complaint regarding a transmission failure in my 2019 Toyota Highlander at approximately 150,000 miles that resulted in a complete loss of propulsion while driving on the highway. My husband was driving to work toward River Forest, Illinois, when he initially noticed that the vehicle would not accelerate beyond approximately 60 mph. After attending practice, he decided to return home rather than continue to the office because of the vehicle’s performance. While driving home on the highway, the vehicle progressively lost the ability to maintain speed. Despite traveling at approximately 60 mph, the vehicle slowed to approximately 30 mph, then 20 mph, and eventually lost propulsion completely. This created a serious safety concern because the vehicle could no longer maintain highway speeds or continue driving normally, potentially exposing the driver and surrounding motorists to a collision. The vehicle was subsequently taken to an independent repair facility for evaluation, and a transmission failure is suspected. The estimated cost to replace the transmission is approximately $5,000 to $10,000. I contacted Toyota Corporate to report this failure and request assistance. Although a case number was assigned, Toyota representatives informed me that they would not escalate the concern without historical maintenance documentation. We purchased the vehicle in 2024 and do not have access to its complete maintenance history. I am requesting that NHTSA investigate wheth

While traveling east on [XXX] in [XXX] on Monday, XXX, the sunroof of my Toyota Highlander 2019 spontaneously shattered. There were four occupants in the car and we all heard what sounded like a gunshot or explosion. There were a few shards of glass that hit my daughter who was in the front passenger seat in the head and small pieces of glass throughout the car. I did not pull over on highway [XXX] because it is a one lane highway with minimal room on the shoulder. I immediately closed the sunshade and put my hazards on and drove about a quarter mile exited safely, pulled onto a side road, and called the police in [XXX]. There were a few pieces of glass that were flying off of the car and towards the car behind us, however, I believe they stayed back a bit because we did suddenly put our hazards on, and I don’t feel that their cars were impacted by the flying glass. No one in the car was physically injured however we were all shaken up. I did call the police because I wasn’t sure what to do and I had three [XXX] kids in the car with me and I needed to know we were safe where we were pulled over. At that time, I also called my husband and he contacted our insurance company to discuss options for repair and how to get three hours home with the car. We chose not to use roadside assistance. The officer followed us a short distance to ensure the glass was not flying out to cars behind us and we were able to safely drive. We drove to the local Walmart where we taped up the sunroof

While driving along, the car suddenly begun not too shift in the middle of an intersection. Fortunately for me, this occurred in the middle of the night when there were not many cars around, otherwise serious injury would likely have occurred since it was in a busy area. I had the car towed to an independent shop first who indicated that the problem was likely a transmission failure. I subsequently had it towed to the Toyota Dealership in Wilkes-Barre PA (Motor World), who confirmed it was complete failure of the transmission, with metallic particles circulating throughout its entirety. According to Toyota, the transmission fluid in this type of car is meant to last the life of the vehicle and regular flushes should not be required. Certainly this appears to not be the case. There were no warnings of obvious symptoms that I could appreciate as a lay person. Toyota is quoting me close to $9000 for the transmission replacement, and I am also currently incurring considerable expense from rental vehicles while I figure out the outcome.

The transmission developed a faint whining noise, first noticed September 2026 around 84,000 miles, along with some hesitation during operation. A Toyota dealer diagnosed internal bearing failure inside the transmission and recommended full replacement. An independent shop also quoted full replacement. Estimates ranged $8,500–$10,000. Vehicle not yet repaired; available for inspection. Safety risk: the noise is faint enough that a driver could reasonably dismiss it as imagined, unlike a loud noise or dashboard warning. No warning lamps or messages appeared at any point. This absence of a clear warning means affected drivers may keep driving unaware a component is failing internally. The vehicle also experienced hesitation during operation, which could affect safe acceleration, for example when merging into traffic. Based on documented failures of this transmission design in other vehicles, continued driving risks progression to slipping or sudden loss of motive power, with less chance a driver recognizes the need to stop before that happens. Inspected by a Toyota dealership and an independent repair shop; not inspected by manufacturer corporate, police, or insurance.

2019 Toyota Highlander XLE, 137K miles. Always maintained, never any issues whatsoever, family loved our 'forever' car, UNTIL the dreaded whining noise began underneath the front floorboard. No warning, no indication, just started while driving on the highway and increasingly became louder over the two additional months I drove it. Quick online search indicates this is a very common issue. Brought to a local dealership in Southern NH, where it was quickly diagnosed as a failing transmission in need of replacement. No warranty, out of pocket cost approx. $8K. Just so happened they had a spare, remanufactured transmission already in house, since this was becoming a 'common issue'. They even had what sounded like a dedicated technician that did at least one replacement a week and had the repair time down to a science. No other warning signs, no software codes, no jerking or slipping while driving, just the noise that increased as the gas pedal was pressed. Well known issue, yet no recall for the 2019 year. Toyota forums indicate the replacement transmissions fail as well after accumulating some miles, which might explain why they only offered me a 1-yr warranty if I had replaced mine. It's for this reason I traded in this Highlander vehicle, as this vehicle was no longer safe or suitable for any long distance family driving. It was also my wife's primary vehicle to transport my young daughters, and I believed that the Highlander would have soon left them stranded. I even purchas

My 2019 Highlander was driving totally normal, when all of a sudden the transmission started slipping and then would no longer accelerate. I was on a windy back road in Alaska with no service, so after letting it sit for a bit I tried to drive it again.

The transmission (power train) in this vehicle shows symptoms of a known defect in Toyota's UA80 8-speed. Since approximately (Aug 2026/~70k mileage), it has produced shining/grinding noised at increasing speed. these symptoms match failure patterns described in Toyota's own Tech Service Bulletin for transmission, which have led to documented cases of sudden power loss, gear slippage, and complete failure in other owners of this and related models. I have not yet experienced complete loss of propulsion, but given the documented failure patterns, there is a foreseeable risk this could occur without warning while driving, including traffic or while merging, creating a safety hazard. I took the vehicle to Toyota of Manchester, NH dealership on [XXX] and requested repair given the known TSB coverage. Toyota denied repair assistance, citing lack of dealer service records, despite transmission fluid being a lifetime-fill component unrelated to this failure mode. I am filing this proactively due to the documented risk of sudden failure, and because Toyota denied to address a known, symptomatic defect before it progresses and declined to take responsibility for the repairs or repair assistance for this defect.

The UA80 8-speed automatic transmission failed at 87,896 miles. Symptoms began as slipping in 1st and 2nd gears and harsh jerking when accelerating from a stop, with the engine revving while the vehicle failed to move. This is a loss of motive power that can occur without warning in traffic. On 8/31/2026 a Toyota dealer diagnosed a failed transaxle requiring complete replacement, with a whine traced to the differential inside the transmission, and quoted $11,126.81. This matches the failure mode in Toyota TSB T-SB-0160-18, which Toyota addressed for some 2017-2018 VINs under Customer Support Program ZJC. My 2019 has the same UA80 unit but falls outside that program. The replacement part is backordered with no ETA per Toyota's own case portal. The vehicle is maintained on schedule and available for inspection. Toyota declined goodwill assistance and refused to provide the denial in writing.

The component that malfunctioned is the vehicle’s automatic transmission. The transmission developed a progressively worsening humming/whining noise during acceleration. The transmission is no longer available for inspection because the vehicle has been taken to an independent transmission repair shop for diagnosis and repair. The problem creates a safety concern because the transmission developed significant internal wear or damage and could potentially worsen or fail while the vehicle is being driven. A transmission failure could result in loss of power or unexpected changes in vehicle operation, increasing the risk of an accident, particularly while accelerating or merging into traffic. The problem was reproduced and confirmed by a Toyota dealership. The dealership diagnosed the noise as coming from the transmission and determined that the transmission requires replacement. The dealership recommended replacing the transmission rather than repairing the specific internal component causing the noise. The vehicle was inspected by the Toyota dealership. It is now at an independent transmission repair shop for repair. No police or insurance inspection was involved. There were no warning lights or warning messages on the dashboard before the problem. The first symptom was an unusual whining noise from the transmission area. The noise later changed into a more noticeable humming sound that increases with acceleration and vehicle speed. The vehicle continued to operate, but the ab

My 2019 Toyota Highlander AWD vehicle started making a whining noise around 85,000 miles. This high pitched whining sound occurred while accelerating and became louder and louder with time. I researched the issue and found out that the same issue had occurred on 2018 Highlanders and Toyota issued a Customer Service Bulletin T-SB-0160-18, which addressed the repair and replacement of these UA80 transmissions regardless if the warranty had expired or not. After visiting my local Toyota dealer, they confirmed that the high pitch whine was the final drive noise with the UA80 transmission and the exact same issue as the 2018 Highlander. If left unchecked, my transmission would eventually fail. Since my 2019 Highlander is not part of any recall, and at the moment, not part of the Customer Service Bulletin T-SB-0160-18, I was left to take care of the repair on my own. I contacted Toyota Corporate and requested financial assistance on the the approximate $7,000 charge to replace my transmission. Toyota told me that my car was not under warranty, but they could pay for my 50% of my cost to replace my transmission. I had to pay $3,535 (half of the total cost) to repair my transmission. Since this issue is a manufactured flaw with the assembly of the transmission, I believe the entire repair should be covered 100% by Toyota; therefore, a recall should be issued or the 2019 Highlanders should also be included in the Customer Service Bulletin T-SB-0160-18.

My 2019 Toyota Highlander has the same UA80 transmission that Toyota was required to fix under CUSTOMER SUPPORT PROGRAM ZJC, which covers 2017-2018, the transmission has the same whining noise and shifting issues.

I have a 2019 Highlander XLE AWD that had 85000 miles when the transmission started whining. It got worse pretty quickly so iI took it to a transmission shop. They rebuilt it for $6700.00. I drove it for another 9-10 thousand miles and the whine is back. I'm not sinking another $6700.00 into another transmission. I've talked to several transmission shops and I'm being told there isn't a true fix. Rebuild it and it will come back, guaranteed. What recourse do I have? The car only has 102,000 miles which is typically nothing for a Toyota. But it all started at 85000. Something needs to be done. I see programs for the 2017 and 2018 models but not the 2019. It's the same transmission. The issues crop up after the vehicle has gone out of warranty.

I am writing to formally document a series of unresolved mechanical issues with my vehicle, culminating in a complete transmission failure, and to request assistance in resolving this matter. The timeline of events is detailed below: *Winter 2024: I first noticed a persistent buzzing sound originating from the engine compartment. Because this symptom primarily occurred during low ambient temperatures, I initially attributed it to the cold weather. The mileage on this vehicle was around 50k miles. *Spring 2024: I contacted the dealership to report the noise. I was advised that the issue was likely related to a worn belt. Subsequent inspection, however, proved this diagnosis to be incorrect, and the root cause of the noise remained unresolved. *Fall 2024: The engine buzzing returned. Concurrently, a severe driveability issue emerged. On multiple occasions after shifting from Park to Drive, the vehicle failed to engage the gear properly, behaving as though it were in Neutral and preventing any acceleration. This would occur while driving and stopped at redlights, which posed a major safety concern as I was transporting my newborn and young child with me. * February 2025: The vehicle became entirely inoperable. Unfortunately, this failure occurred around 62k miles, AFTER my 60k mile warranty expired, (which i was unaware of). Given that these symptoms began during the winter of 2024 and were reported to the dealership early on, it is clear that the initial diagnostics failed to i
