Does anybody else have problems with the driver's side grab handle (above the window) rattling when you go over rough terrain? ('15 LS AWD Fsport)

I finally took mine apart today and am attempting to fix it with some felt, but don't yet know if it worked.

The basic problem seems to be that the rear side does not have a spring like the front does, so it's free to rattle. The mechanism rides on a metal pin that has just enough play in it to rattle. They probably all make noise, but this one is like 6 inches from my ear, so it's very noticeable.
