I have a 2015 Silverado 3500HD DRW High Country with 38,000 miles and very similar issues. The icons on the InfoCenter randomly move all around the screen and then the screen goes into edit mode. The icons move all around and end up on 3-4 tabs, I push the home button and it goes to home screen but in a very short time it will start doing the same thing. Also the clock will randomly load to full screen but most of the time the touch points will not be responsive when these issues occur. This past weekend when I was playing Pandora the screen went from the Pandora screen with the current song details to my Pandora favorite channels menu. The DIC at the instrument cluster now also started jumping to different screens. If I set the DIC to the digital speedometer randomly it will flip to the current Pandora song information. I reset the DIC and in a few seconds the same issue occurs. I took the truck to my local dealer in 11/2019 and they did a software update. I thought this resolved the issue for about 2 weeks but now the issues are more constant than ever. I see several posts with ground issues to replacing the touch screen to replacing the entire radio.
Can anyone give me some feedback as to what corrected your issue and how long since your issue was resolved. I am looking for something more than a few months as I don't want to pay for multiple repairs until the dealer figures out the issue at my expense. After seeing multiple posts with similar issues I took my pickup to the dealer 2 month ago but surprisingly no one at the dealership was aware of any of the issues I had even when I showed them pictures and videos.
