I have the same "issue" in my 2013. My assumption was that the light sensors are adjusting the dash lights to compensate for increased interior light, rather than keeping them dim because the headlights are on. The buttons also stop working when this happens. The first time that it happened, I thought I had picked up a gremlin, but the issue went away quickly and all functions went back to normal. I just don't worry about it when it happens. Nothing else in the vehicle is affected.
