Complaint Summary
POWER TRAIN
Owner Narrative
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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
