Before hitting 100,000 miles the car started making a whirring/whine noise when accelerating. We mentioned it to the service advisor when taking the car in for an oil change. Initially the advisor said the service technicians took it for a drive and didn-??t notice any noise; when we picked up the vehicle asked the advisor to sit in with us to point out the noise to him, he heard and acknowledged there in fact was a whining/whirring noise and said he would inquire about it to the shop foreman. The next day the advisor called me and said the shop foreman stated that noise is a transmission issue.
The transmission started slipping without any warning and then went into neutral while driving and I am not able to drive it anymore. The dealership said the transmission is bad. I see many complaints online about 2020 Toyota Highlander transmissions going bad for no reason. This is a new car only 4.5 years of normal driving and the transmission goes, this is not normal for such a high rated vehicle.
Transmission whining around 38mph when accelerator is pressed. Goes away when foot is off pedal. No warning lights are on. I test drove 3 other 2020 - 2021 Highlanders in May before I purchased this one. All 3 of those had a very noticable transmission whine over 20mph. I opted for this Highlander because there were no noticeable issues/sounds. Just this month, I am noticing a more pronounced high pitch whine during acceleration. This certainly sounds like a much wider issue, especially calling around to multiple dealerships confirming they have other 2020-2021 Highlanders in getting transmission replacements (on 3+ months wait times for parts) This is absolutely a safety issue if a transmission fails while driving. There was a technical bulletin for this same issue with certain VINs, but I was told that my VIN fell outside of that range. To answer rest of questions: No confirmation from dealer on the whine, they are all charging $180 to diagnose the issue and I am not paying that. No further inspections by the above groups listed.

I own a 2020 Toyota highlander and the car mileage is 68,000 and the dealer told me my transmission is dead and needs to replacement. The cost for replacement is $13,000! I-??m the first owner of the car and how could a new Toyota car transmission fail at 68,000 miles and the warranty is 5 yrs or 60,000 miles. This issue have to be Toyota manufacture problems and they should have a recall on this and I researched online and a lot of highlander owners have the same problems as me! NHTSA PLEASE RESEARCH AND HELP HIGHLANDER OWNERS! Thank you

With 55k miles on a 2020 Toyota Highlander, we began hearing a whine. On various on-line sources it appears that this is not unusual among late teens to early '20s Highlanders. I brought the vehicle to the dealer (with close to 56k miles) and the dealer decided the transmission needs to be replaced. Even though the dealer service center acknowledges this is an ongoing issue w/the Highlander of this (late teens/early '20s) vintage I'm told its a 1-2mo wait for a transmission repair/replacement. Warranty is 60k miles... I was told be safe and don't go over 60k miles or its possible the warranty might not be honored. While currently operable, a quick internet search indicates, transmission failure often occurs unexpectedly, leaving drivers stranded on the side of the road. This situation can be not only inconvenient but also dangerous.
My vehicle is started making a loud whining noise at around 78K miles whenever you accelerate between about 25-60mph. The dealer said that a new transmission is the only thing that would fix it. The cost of the transmission is 8K. The dealer said that Toyota ought to cover it, but I called and their initial answer is that they will not. This part should be recalled, there are multiple people online saying they are experiencing the same exact issue. This is a very expensive problem for this car, and not one that consumers should shoulder at low mileages.

The transmission has gone out. We noticed a whining noise which prompted getting the vehicle inspected which led to the diagnosis. The vehicle is at the dealership and cannot be driven as driving it will void the warranty. The were no warning messages just the whining noise at about 30-40 mph. We were told it was good that we caught it as the car could have broken down at any time which could have been a safety risk if it had all of a sudden stopped in traffic. We have researched and found that others have had the same issue. The transmission is on back order with no set arrival date.
