Consumer Description

My 2020 Toyota Highlander is equipped with Toyota’s UA80 8‑speed transmission. At around 62, 000 miles, a loud whining noise developed. The dealership confirmed the transmission is defective. Toyota has issued multiple Technical Service Bulletins acknowledging this transmission defect across all 2020 Highlanders with the UA80, but they are refusing to cover my repair because I am slightly over the 60,000‑mile powertrain warranty. Impact: This is a confirmed design flaw that affects every 2020 Highlander with the UA80 transmission. I rely on this vehicle as my only means of commuting to work—if the transmission fails, I will lose my job.
