In the mornings when the air is on, a small amount of air blows through the windshield defrosters. Condensation and a good amount of water builds up on the outside of the windshield. I have complained and was told in Central Florida we have humidity and dewpoint. Yes, I am 47 years old, born and raised here in Cnetral Florida, I am aware of these attributes of living in this area. This is the 13th vehicle I have purchased in my life and the first vehicle where this is an issue. All of these vehicles were purchased in Central Florida. I took the car to the dealership where a young man explained heat, humidity and dewpoint to me. This information was not news to me. I was told to turn the air to 65 degrees and select the option where the air will come from the outside of the car rather than circulating from inside the car. This does not work. This has been an issue since I purchased the car 2 months ago. GM says there is nothing wrong with the car and will do nothing about it. Therefore, this WILL be my last GM product.
