2022 Toyota Highlander

Toyota 2022 Highlander XLE AWD has a safety issue with the drivers side mirror. The issue is that the mirror vibrates when driving over small bumps or imperfections in the road. It is especially hazardous when driving at night and the following vehicles headlights flicker the reflection back in your face. It is very distracting to the driver. Toyota has similar vehicles (Rav4) that have TSB's for the same problem. Also many Lexus vehicles have similar TSB. I hope NHSTA will convince Toyota that the Highlander with mirror vibration problems need to be addressed similar to the Rav4 and Lexus models.

December 2022 I was driving to my Toyota dealer which is about an hour away from my home for a routine 10k oil. change. Air temperature here in Minnesota was 20-25 degrees. After 10 minute of highway driving with front defroster activated, all windows including the front windshield had some fogging. The fogging continued to spread on all windows. I made several adjustments to the climate control settings but nothing improved the fogging. By 30 minutes into the drive frost was forming at the top of the windshield and side windows where hot air was not blowing directly on the windows. My wife and I pulled off the road several times to wipe moisture off of the glass and sometimes scrape frost. I reported the issue to my dealer in St Cloud Minnesota and inquired if there was something I was doing wrong with the climate settings. They made a couple of suggestions which I thought I had originally tried, but it didn’t seem to be something they were aware of as being a wide spread problem. I made the return trip home with no improvement of the fogging/frost conditions. The problem continued each time we drove the car. We did not use that car again until January 15, 2023 when we traveled to Arkansas for a week. On the 650 mile trip down we had the same issues as before with defrost on high until the temperature rose to the 40s. Before our return trip home, I began researching my problem and found T-SB-0020-19 and T-SB-0024-22 which described my issues. The 650 mile trip was in temperatures from 28-32 and we needed to use the defrost during the entire trip. I scheduled an appointment with Toyota for February 1, 2023. Temperatures were now below zero and did not feel I could safely drive 1 hr to the dealer for the repair. Having extensive experience with auto repairs, I followed the instructions in the TSB and found the exact defect described. I completed the repair which fixed the problem. The 2022 Highlander is not listed in the TSB used for the repair nor any I could find.

I'm reporting this problem as follows. Drivers side mirror (glass) at speed exceeding 20 miles an hour vibrates causing issues with me seeing traffic coming up beside me on the drivers side. This problem with vibration only gets worse at highway speeds. This is a known problem to Toyota. When I took my new Toyota to the dealership I was told that both the dealership and Toyota were aware of the problem with the mirror but could do nothing to correct the issue. My conversation was with Clyde Sanders Service Manager at Riverside Toyota. I was told this issue goes back about two years starting with the 2020 year model. There are numerous post on Toyotas forum talking of this issue. This is not a one off issue but is tied to ALL Toyota Highlanders. I'm reporting this issue because I believe it is a safety issue that needs to be corrected.
