Same rolling sound in my 2018 Silverado. OMG, after weeks of those screws rolling around, that sound like marbles. (BTW from the drivers seat it sounds like it’s coming from the right dash, and from the passenger seat it sounds like it coming from the drivers side dash… crazy). Found this post, and watched the “fix 2018 chevy loose ceiling console ( no special tools)” on YouTube. The hardest part was putting the screws in. I ended up having to put a little tape around the tip of the screws to keep them in the housing then put the panel back up. There was no way to get my fingers in there to hold the screws in place to tighten. (Not gonna tell you how long it took me to think of that. Your welcome:-)
