2020 Toyota Highlander l developed a whining noise and after extensively researching this sound it seems like its common on highlanders with the UA80 transmission and leads to transmission failure. There is a Toyota forum where owners have gathered about this issue not only for this year highlander but early models when the specific transmission above started being used. Quotes to replaced this transmission range from $6,000-$13,000 at the dealer. Toyota has been called and they have been of no help to anyone. Even worse it seems all places are backordered on these transmissions and owners are left without a car. To quote a toyota member who called to get hemp with the issue, this is what Toyotas response was: aœ Toyota refuses any support stating that ‘we can’t predict an average life expectancy for any specific part of component’, This only means life expectancy on their parts does not exist? Shouldnt they have a target life expectancy on parts? A lot of dissatisfied toyota owners as toyota is hiding from this issue.
