Same issue for me, four or five times a week. Believe there are a couple threads on this. Hope my work around works for you.
My work around is akin calibrating our B&W TV when I was a kid. Back then it was slap the side of the TV. Picture steadied, for a while.
To get my cruise control button to work, I "flick" my finger at the cruise control button and in the general vicinity. Can take one to eight "flicks" and the cruise button will function again after I push it.
My work around is nonsense. But it works. And is better than $100 deductible with my million mile warranty. That is assuming the RAM tech can duplicate my cruise control button not working.
