NHTSA Complaint #11708422 — 2021 TOYOTA HIGHLANDER

I bought my 2021 Toyota Highlander on 11/17/2025 and approximately one month later, I heard a whining noise when the car accelerates past 25 mph. The whining noise gets progressively louder the more the car accelerates. In addition, when driving over a bump or hump, there is a grinding/creaking noise that occurs. I took my car into the Toyota dealership on 12/29/2025 and the service technicians were able to replicate my issues. They even stated that the issue is caused by a bearing failure inside the transmission. I also purchased an extended warranty but unfortunately the inspector sent by the warranty company wants me to get a transmission fluid exchange because they think that will solve the issue. The entire transmission needs to be replaced.
