Vehicle visibility issue. All inside windows fog up on a regular basis during cold weather driving. Visibility becomes completely blocked making driving very dangerous. A layer of ice actually forms inside the windshield which takes up to 20 minutes to clear using just the vehicles defrosters with the fan set to the highest speed. The front driver and passenger windows do not ever clear completely in cold weather. This is very frustrating as I have never had this happen on any of my previous GM vehicles. This is an ongoing problem and if a fix cannot be determined, I may be forced to replace this vehicle.

I am 6ft 1in tall and when I sit in the truck with the seat in its lowest position, leaves me with 1-2 inches of head space, I can not adjust the outside mirrors enough to safely see down the sides of the truck. The mirrors do not flair out or up enough for me to safely see into the adjacent lanes on either side of the truck. I sat in several Tahoe and the mirrors were all the same. I have remediated the problem, some what, by attaching a convex mirror to each of my side mirrors. When the mirrors are fully flared up and out, half of the image I see in the mirrors is of my own truck.

2011 Chevrolet Tahoe. Consumer states problem with windows fogging up the consumer stated while driving, the windows began to fog up on the sides. The consumer believed the problem had to do with the temperature drop by a few degrees. The consumer stated the third time while driving, the front windshield became fogged, and then all of the windows fogged up. It took over 20 minutes to clear the windows. The dealer informed the consumer a bulletin had been issued which stated the recirculation door was not closing all the way. They also stated GM tech's had no idea what was causing it.
