Highlander

My vehicle was taken into Toyota dealership for diagnostics after experiencing a whine noise from transmission after driving. Toyota confirmed that I will need a new transmission. After researching I found that there is a defect in the transmissions for my specific type. It has been reported for years but Toyota has not addressed. Since it is a transmission failure this could lead to a breakdown while driving on highways and could risk my safety and other drivers. The estimated repair cost are currently above $8K.

Owners of 2017–2022 Toyota Highlanders, 2017–2020 Siennas, and 2018–2020 Camrys are experiencing 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. Toyota quietly acknowledged the problem in Technical Service Bulletins T-SB-0160-18, T-SB-0008-21, and a limited Customer Support Program (CSP ZJC)—but only offered coverage to a narrow group of VINs. Thousands of other affected vehicles were left out, even though they show the same exact symptoms.

This is the second time this year 2025 my Toyota Highlander 2019 stalled fist in the middle of of intersection and second on the drive thru in in&out. Suddenly my car died. Tried to turn on followed the on screen instructions but the car failed to turn on. The first time it happened in the middle of the intersection while waiting for the light to change, after the issue I when straight to a car shop and oreilly they have this machine to check any possible issues and he said nothing shows in his machine but he think it’s the battery but I told the guy my battery and on the car shop Midas same result no major issue found and one of the technicians says It could be the auto shot off features, that must be manually turn off since this will automatically turn on. The second incident in In&Out the car died suddenly, tried to turn the car but it was on Drive so change to stop then tried to turn on multiple times but faulted , the crews decided to help us push the car out of the drive thru since we are blocking all the customers car, the steering wheel so stiff could hardly turn. We can’t change gear from stop, I was told to push off and on manual break foot pedal and this this help able to change gear to neutral, so we can push the car out of the drive thru. No message or failure message in the screen. We just push the car in the parking lot. Tried to turn on but failed. One of in&out staff was so kind to help us, he has a portable jumpstart and the car able to start. Able to drive home safe. Now I’m afraid to turn on my car or drive far distance due to this issues.

Transmission failure. Vehicle is at this time still operational however the transmission has developed the ever so common whining sound and sluggish shifting. Upon fluid inspection metal filings can be seen and replacement has been recommended by repair shop. The whining has been evident for some time but after investigating this issue decided to have inspected. This inspection was just completed on 11/14/25

Our 2019 Toyota Highlanders transmission is gone. The car has 83,000 miles. I have been researching online and found out that Toyota is very much aware of the problem. They're refusing to help me. They're basing it on our VIN#. No recalls. I just want them to acknowledge that the issue needs to be addressed NOW.

The contact owns a 2019 Toyota Highlander. The contact stated that while driving approximately 35 MPH, there was an abnormal whining sound coming from the vehicle. There was no warning light illuminated. The contact previously owned a 2017 Toyota Highlander and heard the same whining sound coming from the transmission. The contact stated that when the 2017 Toyota Highlander was taken to the dealer where the vehicle was purchased, the contact was offered a trade of the 2017 Toyota Highlander for the 2019 Toyota Highlander. Following the failure of the 2019 Highlander, the vehicle was taken to two different dealers to be diagnosed. The first dealer had not diagnosed the vehicle but stated that the vehicle was operating normally. The vehicle was taken to another dealer, who diagnosed the vehicle and determined that the transmission needed to be replaced. The vehicle was not repaired. The contact researched the failure online and determined that the 2017 Highlander and the 2019 Highlander had the same model transmission, UA80F - CVT transmission. The manufacturer was informed of the failure and informed the contact that the vehicle was no longer under warranty. The failure mileage was approximately 133,000.

Loud ear-piercing noise when vehicle is started. Noise lasts about five seconds.

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.
