My 2020 Highlander developed a whining or grinding noise consistent with the Technical Service Bulletin. I took it to a Toyota Dealership for diagnostic and they confirmed the whining and hissing sound. They said it would cost $9,000 to repair. I called Toyota to request a goodwill repair and they denied me. Toyota case number: 251229000423. The car does not feel safe to drive. We worry that at any moment the car could break down with our children inside. The problem was reproduced at a dealer and inspected. There were no warning lamps or messages, just the obvious sound coming from the transmission.

Shortly after the powertrain warranty expired, the automatic transmission in my 2020 Toyota Highlander began producing a loud whining/howling noise during normal driving. The noise appears to come from the transmission area and increases with vehicle speed. The issue was not present during the warranty period and began unexpectedly soon after expiration. The abnormal noise raises concerns about internal transmission failure and potential loss of drivability. This condition could pose a safety risk if the transmission were to fail while driving, especially at highway speeds or when merging into traffic. No warning lights or messages were displayed prior to or during the issue. The vehicle was inspected by a Toyota dealer, and the problem was confirmed to be related to the transmission.

We were driving in the freeway and suddenly we heard like a "bang" sound, like an explosion. We looked around us and wondered what it was. Then we heard the air from the roof seeping through and we took an exit, it was a shattered sunroof.

My 2020 Toyota Highlander Hybrid has a braking issue identified in Toyota Service Bulletin T-SB-0059-23, Hybrid Regenerative Brake Transition Feeling Improvement. When going downhill and applying the brake, the vehicle lurches forward temporarily as the braking system transitions from regenerative to hydraulic braking. The first time my vehicle did this, it was very alarming and I had to take additional measures to slow my vehicle as I was driving downhill. My vehicle frequently demonstrates this problem, however, I did not report it to my local Toyota dealer because I read in an online chat group that it was a characteristic of this vehicle. Although the TSB recommends a Reprogram of the Brake Actuator Assembly Control Module, the repair is only covered under the Toyota Basic Warranty whi

We recently purchased our highlander and it has a little over 4,000 miles. Today while driving down the road at about 45 MPH, the car just lost power and the check engine light came on. 1. Check engine - reduced engine power 2. Secondary collision brake system malfunction we had to park and wait for the Toyota dealership to come and tow it to the service center.
