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.

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.

1. What component or system failed or malfunctioned? System: Power Train: Automatic Transmission Specific Component: UA80 8-Speed Automatic Transmission (Internal Failure) Available for Inspection: Yes, the vehicle is currently available. 2. How was your safety or the safety of others put at risk? While merging onto the highway, the transmission failed to upshift, resulting in a sudden and unexpected loss of acceleration. The vehicle could not reach or maintain highway speeds (speed limit). This created an immediate hazard as I was unable to keep up with the flow of traffic, forcing me to make an emergency exit across multiple lanes while moving significantly slower than other vehicles. The loss of motive power increased the risk of a high-speed rear-end collision. 3. Has the problem been reproduced or confirmed by a dealer? Yes. The problem was confirmed by Heritage Toyota Service. The technicians confirmed an internal transmission failure. A secondary consultation with a transmission specialist (AAMCO) also identified the failure as a known mechanical defect common to this transmission model. 4. Has the vehicle been inspected by the manufacturer... or others? Yes, it has been inspected by the authorized Toyota Dealership listed above. I have also reported the issue to Toyota Brand Engagement (National), but a corporate field inspection (DSPM) has not yet been performed. 5. Were there any warning lamps... or other symptoms? Symptoms: A distinct whining noise from the engine/transmission area that increased with vehicle speed. Prior Events: The vehicle was taken to the dealer specifically for this noise. The dealer performed a fluid change and released the vehicle. The catastrophic failure (loss of power) occurred less than 24 hours after leaving the dealership. No dashboard warning lights illuminated prior to the loss of power.

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.

The car started making a wining noise while accelerating. The car was brought to my local dealer where I always have my service done and they said I need a new transmission. The cost will be approx. $9,300.00. The car has less than 84,000 miles on it and is just 6 years old. Every recommend service has been done to date.

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.

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.

ENGINE
In early January 2026 there was rough/delayed shifting, whining noises, and fluid leaks. Probably linked to the faulty UA80E/F transmission type. The check engine light came on 1/15/26, I took it into a local repair shop. The mechanic flushed and changed the transmission fluid, replaced all of the spark plugs and the serpentine belt. I picked it up on 1/16/26. There was still shuddering, strange sounds (whining/grinding), and hesitation. On 1/20/26 I drove it and the rough/delayed shifting, whining noises, hesitation and burning smell started happening. The car completely broke down on the freeway and wouldn't drive at all. I had to slowly pull over to the shoulder of the freeway and have the car towed to the repair shop. They inspected it and said I need a new transmission, and it cannot be fixed. I believe the next steps are to have it towed to the toyota dealership to have it looked at.

I am experiencing a turbine whining noise from my transmission while under load. This has been reported to be an issue that stem from incorrect assembly of the locking washer to the locking nut in the UA80F 8 speed transmission. Toyota only provided extended warranty to 2017-2018 vehicles but not all vehicles that were manufactured with the same exact transmission. This whine is a sign of premature transmission failure that can occur at any given time while driving which is an extreme safety hazard. Please do something to force Toyota to be held accountable of their poor manufacturing and fix this safety hazard via recall. There is a law suit from James LeBoutheller pertaining to this issue.

Transmission failure resulted in sudden loss of power while driving, creating a safety risk in traffic. Vehicle was unable to accelerate and required immediate repair. Put myself and my children at risk, as the car suddenly died while I was driving it. Prior to this, there were not issues. Has been routinely maintained and only has approx 83k miles. Toyota agreed that the transmission is the only issue with my car but won't cover the cost to replace it (10k) or the cost of a loaner vehicle. I have been without a car for almost a month while the (refurbished) transmission is on backorder.
