2023 Toyota Highlander Wipers & Visibility Problems

Your rear window spontaneously shattered while you were driving on the freeway in light rain shortly after turning on the rear defrost. There were no warning signs or symptoms before it happened. The repair will likely involve replacing the entire rear window glass.

Your driver's side mirror was damaged during service and now shakes and vibrates while driving, making it difficult to see clearly on the highway or bumpy roads. The dealership attempted repairs and replacement, but Toyota determined this vibration is a design characteristic of the power-folding mirror and declined further repairs. Fixing this issue would likely involve replacing the mirror assembly or addressing the mounting mechanism that's causing the vibration.

Your side view mirrors vibrate noticeably at speeds above 25 mph, especially on the highway, making it difficult to see clearly when changing lanes. The vibration is particularly noticeable on the driver's side mirror, and you've noticed that tapping on the door from inside creates a similar vibration in both mirrors. The dealership inspected the mirrors and found them to be secure, but the issue persists. The problem likely stems from how the mirrors are mounted to the door panel, which transmits road vibrations to the mirror assemblies.
