We experienced the exact issue the recall was issued for stalling while driving. Issue on July 24, 2027: The engine stalled while driving on the highway at high speed and lost power steering, creating a major safety issue. We had our vehicle towed to a car care center.

Vehicle is a 2017 Toyota Highlander (VIN [XXX]) experiencing the UA80 8-speed transmission whine defect (T-SB-0160-18) upon acceleration. An authorized Toyota dealership test drove and officially verified the transmission failure and recommended a full replacement. However, Toyota Corporate is refusing to honor the ZJC Customer Support Program warranty extension due to an arbitrary VIN cutoff. The failing internal transmission components pose a safety risk as they can lead to harsh shifting, slipping, or a sudden loss of motive power while driving in traffic.

Vehicle had history of hard shifting from 1st drive. On January 24, 2026 we heard a ringing sound as we were driving. Approximately 10 minutes after the noise began, the Check Engine light illuminated. We drove back home and connected our code reader to find P0741, P2714 and P2757. Had the vehicle towed to my Toyota Service Center and upon inspection, was informed that the transmission had failed and would require replacement. I was informed that although it was a 2017 with the UA80E manufacturered in April 2017 - it did not qualify for free replacement under Toyota. A rebuilt unit was secured and installed on 2/11/26. Toyota authorized $2000 Goodwill Assistance and their Warranty Labor Rate. I paid the remainder of the bill. The 'new' transmission also shifts hard and just doesn't feel like it it working right.
