2013 GMC Terrain wipers, windshield & visibility problems

This is a life threatening situation. At night the top 3/4 of my windshield goes dark. I cannot see oncoming cars, road lanes, or side lines. This is like driving through overly tinted windows....when turning on unlit roads cannot see a thing. I cannot drive this car after dark..prisoner of the clock. My dealer tells me this is his fifth complaint re this matter. Help!!!!

I was driving in the rain and my front windshield wipers went out. I had to pull over and stop to avoid having an accident. I could hear the motor running but they would not move. I parked my car, got a ride home and went back and picked it up when it stopped raining. The next day I took it to the shop and dropped it off for repair. I was told that it was the transmission that was inoperable, but the warranty would not cover this. I paid $285.21 to have this repaired on 9/9/16.
