I noticed vent trim reflection on the passenger side as well when viewed from the passenger seat even when it was cloudy out side.
If the reflection is actually seen on the window glass as opposed to side mirror, may be window tinting would help? Anyone with aftermarket tint can verify and let us know?
Also, while driving in light rain at night in the city, I had hard time getting a clear visibility while driving under street lights. May be the steep angle of the wind shield results in glare in such conditions. I came home and immediately applied RainX on the windshield, hope that will take care of the problem.
