2019 Chevrolet 2500 HD Duramax LTZ. These issues started several months/4k miles ago and have progressively become more frequent. Truck currently has 60k miles on it. Note that I have performed the following several times: System update (current). Infotainment system Reboot (current). Calibrate touch screen. Infotainment screen: Freezes. Will not respond to touchscreen touches(?). Home button & other manual buttons work including volume/channel knobs, HVAC controls & steering wheel controls. Was intermittent but seems to occur more now that warm weather is here. Switches from one display to another. Ex.: Displaying radio info, display changes to the navigation screen. Then it will start scrolling the displayed map w/no used input. Turning off/on the screen changes nothing. Turning off the vehicle completely resets the display (usually). Allowed to cool off completely does reset the display. Maybe heat related? Instrument cluster screen: When looking at the 'Info' screen, display changes to Audio display w/no driver input. Driver returns to 'Info' screen; system changes it to 'Audio', etc. See above to reset. Any suggestions would be appreciated.
