problem #2

Jan 012025

Highlander XLE AWD 3.5L V6

  • Automatic transmission
  • 47,846 miles

Car starts whining noise when the gears wind down (from higher to lower gear, accelerator not stepped on). Noise stops when gear is put on neutral while car is running. Dealer took it in under warranty (5 years expiring in August 2025), however, Toyota Canada has the transmission backlogged and NO ETA!!!! We thought Toyota was the way to go for long term reliability - this one, we are mistaken. TSB for 2019 and 2021s but none for 2020!

Highlander Limited 3.5L V6

  • Automatic transmission
  • 106,000 miles

Our ‘20 highlander started making the know whine while driving. There is a TSB one some of the trans model numbers but this issues is effecting 20-21 trans it is a different issues than the 17-19 issue of a bolt or washer backing out. This an issues with the front carrier assembly pinion shafts. TSB number T-SB-0008-21. This is a know issue with the UA80 model transmissions. I am hoping that Toyota will have a recall on these as the wait do an new 7-10k transmission is over year wait and they don’t have any other fix than a new transmission on a 5 year old car. This inexcusable we have had Toyotas for years.

We are teachers and can’t afford to pay on this car and find 8k on top of that to drive our highlander. They need to at least cover the trans as this a major issue effecting so many models you can even get it fixed because they can’t keep up with the demand of broken parts. Come Toyota do the right thing.
