OK I've determined that it's not a sunroof issue (90% sure). Somehow there is this metallic tapping sound emitting from the rear of the roof/ceiling area. I just couldn't figure out where. The last time I brought it to the dealership they did the sunroof recall thing + added some greasy prints on the headliner. I like to avoid the dufusship experience again if possible. Any thoughts?

 

Maybe they lost a nut back there.

 

Aww great! that's what I feared.

 

Logically speaking, doesn't it have to be the sunroof? That's the only thing up there with moving parts.
