Wiper problems of the 2019 Chevrolet Traverse

My complaint is in regard to the climate control system on my 2019 chevy Traverse. I chatted with will of the Chevrolet customer service center on October 10, 2021. The problem is that the system will not keep the windshield clear of fog in certain weather conditions. During the chat, will said that he couldn't do anything unless I had taken the car to the dealer. I believed it is a design flaw, because my son owns the same model and year of Traverse and has the same complaint. (I have previously owned 2009 and 2012 Traverses and did not experience this problem. ) the next time I took the car to my dealer for service 12/14/2021, I told the service dept about the problem. According to the service request: "all functions working as designed at this time. " the service manager told me that this is a common complaint. He suggested using the "max defrost" button (which bombs the driver with air), turning on the ac to take the humidity out of the air, and turning up the temperature. We have had this fogging happen at many times. But is not something that can be replicated, because it is dependent on the weather. The time I complained in October 2021 was particularly scary, because I was bringing my husband home from surgery late at night from montefiore hospital in pittsburgh. The hospital is about 2 hours from our home and is not a trip we make on a regular basis. It happened on Friday, may 6, 2022 again, when my husband was going to monroeville, PA for a check-up with the vascular surgeon. It was one of those "all day rains" and the temperature was in the 52-58 degree range. I think we both had a stiff neck the next day after having the max defrost blasting all the way to pittsburgh and back.

Driving on freeway all of a sudden sunroof just shattered.
