Recently, my Denali shows Collision Avoidance Unavailable and ACC Unavailable when I start the vehicle up in the afternoons for my commute home. Last week it was due to the heavy pollen on the windshield. Now that's over and I washed my Yukon two days ago (i.e., my windshield is crystal clear). Has anyone else had this problem? Is there something I can check?
