My truck is a 2019 GMC Sierra 2500HD 4x4 Denali with a 6.6 Duramax. The chirping is random and makes the IntelliLink go crazy. The screen changes without me touching it, then it will scramble sometimes. It doesn't do it every day and temperature doesn't seem to be a factor. I live in Southern Alabama, but it happened while I was in Colorado in sub zero temperatures. I feel like it has something to do with the Bluetooth connection, but not sure.
