NHTSA Complaint #11680607 — 2021 TOYOTA HIGHLANDER

Started hearing a whining noise when I would accelerate and then my car bucked a couple of times. I brought it into Toyota on 8/07/25 to be checked out and I was told that my transmission would need to be replaced. My car is 4 years old, bought brand new in April of 2021 and have kept up on regular maintenance. In researching this I am finding out that there is a large number of people who are experiencing this same thing with their Highlanders. I have also come to find out that in February of 2021 there was a TSB put out with regards to this same issue. This was 2 months before I even purchased my car. It for some reason does not include every vehicle and only some vehicles are included leaving others with this problem out of luck. I do not understand how that can be. If I have that UA80F transmission in my car and that is what is being named as one of the transmissions that have this problem then why is that certain vehicles are not being taken care of and why is Toyota not issuing a recall? My warranty has expired so I am being expected to pay out of pocket $8,000 (not including labor) and on top of that they do not even have the parts as they are on back order. We have to hold Toyota responsible for this.
