Need a few details of what is going on. Do you mean if you hit the cruise on switch on the steering wheel nothing happens? If so that is pretty common to have issues with that button and there have been dozens of post over the years talking about it. I have a '16 with the same issue. It will go months where if you just hit the button the cruise will not turn on....but if you have sit there and constantly hit the button on and off, and sometimes hit the other buttons randomly, it will then turn on. Then you will go for months with no issues. Some people report smacking the steering wheel around the button will get it working. In any case it's either the button is worn out, a loose connection, bad wiring, or even a clock spring issue (though usually multiple other steering wheel controls will not work). On mine it's only the cruise on button and nothing else.
