NHTSA Complaint #11687960 — 2022 TOYOTA HIGHLANDER

I own a 2022 Toyota Highlander XLE (UA80E transmission, ~66k mi). The vehicle exhibits a severe transmission defect: uncommanded braking/drag at 35–40 mph and sudden loss of power when accelerating from a stop, making merging/crossing intersections dangerous. Two Toyota dealers (Bryan Toyota and Plano Toyota) reproduced the issue, documented the vehicle as unsafe to drive, and recommended full transmission replacement. The failed unit is preserved at the dealer for inspection. (Toyota Corporate Case #250917001779.) This mirrors long-standing defects within Toyota’s UA80 family that Toyota itself has documented: • Customer Support Program ZJC / POL19-04 (4/18/2019)—UA80 whine, harsh shifts, reduced power 2019 MC-10159730-9999 . • T-SB-0160-18 Rev1 (12/17/2018)—UA80 whine/harsh shift/MIL/reduced power 2018 MC-10198131-9999 . • T-SB-0001-18 Rev2 (1/8/2018)—ECM/UA80 mismatch causing harsh shifts 2018 MC-10185780-9999 . • T-SB-0008-21 (2/9/2021)—UA80E/F failures in 2021 Highlander (whine/grind, pinion shaft) 2021 MC-10188917-9999 . The same safety-critical behavior now recurs in my 2022 model. I request NHTSA investigate this as an ongoing UA80 transmission safety defect trend and consider recall/coverage for affected vehicles.
