Add my 2017 Silverado to the list of those with "possesed" radios - started changing stations on its own this July at 70,000 miles. Irritating & distracting, but what has led me to seek out this conversation is b/c today I cannot set my clock b/c the touch-screen is unresponsive. I appreciate being able to read what you're sharing & I look forward to more updates. [Just yesterday, wonderful husband checked the grounds & cables for another Silverado issue - temperature gauge / AC compressor / radiator fans - & fortunately all 3 are working again.]
