FUEL/PROPULSION SYSTEM
Vehicle engine is running rough and threatened to stall in traffic due to a failed low-pressure fuel pump. This model year is under a major fuel pump recall, but my VIN was excluded. The gauge isn't reading correctly either

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 purchased AAA tow service for the first time in my life at [XXX], all because of this known transmission issue. I now warn everyone who is searching for this SUV to be very aware.

POWER TRAIN, ELECTRICAL SYSTEM
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. It then drove maybe 1/2 more miles before slipping completely and no longer accelerating. No check engine lights came up. I got it towed to my house where a mechanic took a quick scan and said there was a number of transmission codes popping up.

UA80 Transmission failure. Was driving on highway when the transmission failed and lost power to the vehicle. Car was taken to Sunshine Toyota (Batte Creek MI) in 2022 and the transmission was recommended to be replaced due to a defect at 67,000 miles. The car was then sold off, and I acquired it through another dealer.

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 abnormal transmission noise persisted and progressively became more concerning.

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.

The back passenger door (passenger side) will not unlock when using the remote or the button on the front door panels. The only way to open the door is to push the button manually on the car door. The child lock is NOT ON!!! I called the Toyota dealer in my town and they said there are no recalls and it would be $200 to do a diagnostic test on it. This is not ok. To not be able to unlock the door from the remote or the front door panel is not acceptable.

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. Toyota must accept responsibility for their manufacturing error where the washer tab was not bent properly, allowing a nut to loosen leading to the whining noise. I expect the NHTS to require them to cover their 2019's as well, as a consumer we are getting screwed here.
