Yesterday on the way to work in the morning, it was dark and I noticed a foggy area at the top of my mirror. I ignored it assuming it was condensation or something and didn't want to smear it, figuring it would dry off quickly. When I got to work about 50 minutes later, it had grown in size and lessened in effect. After work, it was still there. It is not on the surface, but seemed to be between layers. Also at the bottom, it looked like a slight double vision issue. The auto dim part still functions, when I was stuck in traffic, I would put my finger over the sensor, and it would get bright, then when uncovered with traffic behind me it would green out.
