I am reaching out regarding our 2021 Toyota Highlander which currently has $65 K miles and is just out of warranty. Recently we noticed a wining noise during acceleration. We took the vehicle to the dealer who told us that the transmission will need to be REPLACED. $9500 repair. This is a known issue with Toyota and they will not work with us on this. We are stuck! No customer goodwill! Thank you!
I purchased my brand new Highlander on January 31, 2021 and was told today that I need a transmission replacement. My vehicle started about two month ago with a whining sound while accelerating. My vehicle currently has 78,000 miles and is out of the extended warranty of 60,000/5 year. I learned that Toyota released a bulletin on February 9, 2021 stating transmission issues for particular Toyota models, the Highlander being one. After researching the issue, there are several stories of Highlander owners who are experiencing the same issue. Itâs a shame that they knew of the problem in February 2021 and with the transmission replacements on vehicles less than 5 years old and havenât issued a formal recall for this known defect.
Power Back Door (PBD) will not open or close and/or stops moving while opening or closing. Problem seems to be in the motor controls of the strut assemblies on both sides of rear hatch. Vehicle is off warranty, but should be covered by Toyota due to faulty factory installed equipment... Instead, they want to charge us $1600 to repair. On the Toyota forums, many people are complaining of the same exact problem! Toyota needs to have a recall and repair at the cost of the manufacturer.
2021 toyota highlander AWD limited - Car started making a whirling (whirring, whining) noise upon acceleration. It ramps up as accelerating. There are no warning lights showing. It stops when you take foot off of gas. Problem had been confirmed by 2 toyota dealers as needing a new transmission. One said it was in last gear, the other simply said noise was coming from the transmission and based on the NSB in 2021 it was transmission so would need to be replaced. One was $9700+, the other was $8600+. Went back and forth with Toyota to see if they would provide any help. They wonât cover any of the cost. Husband has a 2019 toyota highlander XLE making the same exact noise. Havenât taken it yet for diagnostics
The liftgate has had issues from the moment I purchased this vehicle. It had 30,000 miles and we purchased all extended warranty options. The liftgate often fails to close, especially in cold weather. There have been times I have to manually push the liftgate closed certain instances. This would not even work, and I unknowingly started driving my vehicle while the liftgate was still open about an inch or two essentially, the liftgate seems to have a mind of its own sometimes it will work just fine more more often often than not it malfunctions. This is dangerous because it could easily cause a head injury or trap a child or a family member inside the car if it will not open or closed properly. We took the car to our dealership to have it repaired while under warranty. My car care technician reported that there was dust/dirt which voided my warranty coverage. I paid a lot for the warranties and for this woman to report dirt on my vehicleâs backend and that then causing my warranty co

â¢The transmission malfunctioned and developed an abnormal internal noise at approximately 67,000 miles, which is an unexpected failure at low mileage. The vehicle had been properly maintained and had no prior mechanical issues. Atlanta Toyota inspected the vehicle and confirmed the transmission had failed and required full replacement.

The transmission in my 2021 Toyota Highlander began making a loud whining/whirring noise that increases with vehicle speed. The vehicle was inspected by a Toyota dealership, and I was told the transmission has failed and needs to be replaced. Toyota stated the repair would be out of pocket, despite the vehicleâs age and proper maintenance. There were no warning lights prior to the failure. This condition affects drivability and raises safety concerns, including the risk of sudden transmission failure or loss of power while driving, especially at highway speeds. I believe this is a premature transmission defect and am reporting it for investigation.
Toyota is asking me to pay for a brand new transmission replacement in my car that is only 5 years old, 74,000 miles on it. The cost is $10,000. How is it possible a brand new vehicle is needing this? I have read a lot of reviews that Toyota is knowingly using the transmission type that they even had to recall on earlier models. Why are they still making vehicles using this type of transmission when it continues to need total transmission replacement so early on? And Offer zero assistance. We bought Toyota because we thought it was the best. I will never buy Toyota again, this is a huge cost for a young family with a teachers salary.
I am writing about my 2021 Toyota Highlander XLE AWD VIN # [XXX] . I purchased this vehicle brand new on 3/29/2021 at âKoons Easton Toyotaâ in Easton, MD. In October 2025 I started hearing whining noise from the engine compartment. It was audible only when accelerating the vehicle and would go away if I took my foot off the accelerator. On 10/22/2025, I took the vehicle for inspection to âOurisman Toyota 40â dealership in Edgewood, MD. The technician told me that this is a known issue in this model/year and recommended to replace transmission as there was no other fix. He gave me a $9,995 estimate for transmission replacement. I subsequently learned that there was technical service bulletin on this exact defect released by Toyota on 2/9/2021. It said that models with UA80F transmission will make whining noise and then fail. The only remedy was to replace the transmission with brand new transmission part number 30500-0E160. This bulletin was posted on NHTSA website also. [XXX]
We began noticing a whining sound that has progressively gotten louder and more frequent upon acceleration. After taking it to the dealership, they claim it requires a transmission replacement. According to the dealership themselves and information online, this seems to be a common defect with 2021 Highlanders.

I had the 60,000 mile service on February 2,2026 and after the service was completed I left the dealership and got on the freeway to go home. I heard a whining noise and immediately turned around and took it back to the dealer. I took the mechanic who worked on my car for a drive and he was able to hear the winding noise and we returned to the dealership. It took the mechanic three hours to come to the conclusion that I needed a new transmission. They still have my car and I have not heard anything about coverage or when it will be done.
Complete transmission replacement for failure. Toyota said it is an unknown issue but has not issued a recall for 2020/2021 models. THIS NEEDS TO BE A RECALL. Toyota should be responsible, especially because they will not cover it if you go over your manufacturer warranty of 60k. I purchased this car last week, and had to get a full new transmission the following week because they did not disclose to me that it was failing!
Trunk has stopped working. It loudly beeps and will not open on its own. Trunk has to be manually opened and shut with great force to be used.
