Shortly after getting this truck I noticed that when driving at night my drivers side mirror would show cars behind me in double vision. Upon further inspection I realized it was doing during the day to and the problem was worse with object farther away. It made me think I had a vision problem. I have the auto dimming mirrors. The dealership ordered a new mirror and once it was replaced everything was good again. I noticed on two different Ford Fusion loner cars the dealership gave me had the same problem in the rear view mirror as well. It seems only to happen on mirrors that are auto dimming but it is fairly simple to fix.
