Just adding a "me too" to the cam phaser issue. I was lucky enough to capture it in cell phone audio so I could play for the local service tech's. Parts on (back)order, will take it back in when they arrive. Crossing my fingers this is a one-and-done issue for me, as opposed to the OP's experience. :-/
I posted a video above, check it out. Mine does not seem like it is doing it anymore.
