NHTSA Complaint #11562314 — 2018 TOYOTA HIGHLANDER

My transmission started making a whine sound upon acceleration, and at times hesitation of acceleration (inconsistent). Toyota Service identified the issue in 2018 as a defective part from manufacturing and related in the repair notice to Toyota Service Bulletin TSB-160-18 which states certain Highlanders (my year and model) have an issue with a defective part in the transaxle/transmission. Toyota issued an extended warranty for the problem in 2020 (unlimited miles for coverage). I was then told that it then DIDN'T apply to my VIN, even tho it was the problem diagnosed by a Toyota service technician associated with the TSB above, so they wouldn't cover thru the extended warranty. Told me that I have to pay for a new transmission over $9,000. My understanding (I cannot verify) that the initial service bulletin was expanded to cover more models in 2021, then removed the extended warranty, and did not issue a recall. Apparently Toyota is aware of a serious transmission problem caused by a defective part, and it is wider issue. This needs to be addressed as it is a significant hazard and danger Toyota is aware of, and not the cause of normal and expected wear and tear. I need help addressing this with TOyota and want to be sure the problem gets fixed before injuries occur. Toyota has multiple bulletins in the NHTSA data for this issue from before and after this issued bulletin demonstrating on ongoing issue. I tried to upload the TSB and the repair documentation but your system is not allowing
