NHTSA Complaint #11681095 — 2022 TOYOTA HIGHLANDER

Complaint Description: The automatic transmission in my 2022 Toyota Highlander failed completely at only 62,800 miles. Toyota Brand Engagement Center offered to cover 50% of the replacement cost, but I was informed that the transmission is on national backorder with an estimated wait time of 4–5 months. This leaves me without a safe and reliable vehicle for an extended period of time. The failure is consistent with Technical Service Bulletin T-SB-0008-21 (Feb 9, 2021), which acknowledges internal component failures and abnormal noises (whine/grind) in UA80E/UA80F transmissions. A major drivetrain failure at this mileage is unacceptable and raises concerns about safety, reliability, and Toyota’s handling of known transmission defects. I am requesting NHTSA to investigate this issue as it appears to be systemic and affecting many 2021–2022 Toyota Highlander owners.
