The closest I ever came to this issue is pictured below.  This happened to both my (late) '15 and my (current) '18 trucks, oddly, about 3 years into owning either one.


This happened when I went to refuel my truck.  It will "lock back in," but it will pop again on the next refuel.




Went to the nearest hardware store, purchased a bolt, a washer, and a nut.  I may take it apart and put some black RTV (or something similar) between the bolt head and the flange, and then paint the bolt head with my touchup pin.  The one on my '15 started corroding after about a year.
