2019 equinox, fixed a headliner rattle!
Found a rattle coming from left headliner area right near my head. Turns out it was the voice microphone behind the grab handle. It is loosely glued on behind the headliner. You may be able to reproduce it by pressing directly on the plastic microphone cover. To fix, remove the bolts holding the grab handle. Remove it. Peel back the headliner until the black mic unit is visible. You may find tacky glue holding it to the headliner. That is the problem. The unit pulling back and forth causes the glue to make a sharp snapping sound. Remove as much glue as you can and simply duct tape the unit in place. Make sure it is lined up with the hole as the plastic mic cover will need to snap into it.
