Appliques? Do you have a picture or bulletin number?

I am getting a rather annoying clicking/tapping sound at the drivers side footboard by the a pillar where the body mount is. 3 months after I got the 2015 yukon I took it to the dealer they said they couldn't hear it and in their defence it only happens in the early morning an it didn't make the sound for them. Anyhow I loosened and tightened the mount and it went away for about 8 months but all the sudden we get some weather and is starts again. Tried to retighten it without luck. Any suggestions? Has anyone seen this issue before? It almost sounds like a did clicker at times.
