I have found, that when traveling off road in winter, dedicated snow or winter tires are the way to go. They grip the snow and ice better and provide greater control. The rubber is made for the cold, as well. Having a dedicated winter, is the best way to go. Michelin and Nokian are good choices. Work well in timber country or city streets. Worth the extra money.
It might be a bad steering rack. I believe there was a tsb or a recall. You have to find out what’s wrong. Take it to a good front end shop for an alignment and diagnoses. Research the recalls, as well. Bad part might be covered by GM.
I believe I went to the menu and checked the update availability.. The update showed on the screen and proceeded to update the system software. You have to have network. ( WiFi ) activated on the vehicle.
Now have an Exxon app and Shell app to purchase gas. There are a few others you can activate.
