The “rattling” I am referring to below, is more like a pen-clicking sound.

I am also now experiencing driver-side c-pillar rattling at about 4.5-4.6k miles. Sound is more prominent in sport+ chassis, though there is still some rattling in comfort chassis. In either mode, the sound is intermittent as it does not always occur over bumps or uneven roads, but occurs moreso on the highway at higher speeds. This is bizarre as I did not have any recent work done, but I did have my rear driver window replaced (at around less than 1,000 miles), for which I assume they had to take apart that panel and airbag area.

Update: I believe the sound has become slightly louder and prominent over bumps and uneven roads at lower speeds.

Anybody have a similar situation?

I have something similar except it sounds like its coming from the front windshield... almost like a tiny rock hitting the glass except there are no vehicles or trees around and too cold for bugs. Very random when it happens but sounds like a tiny rock or pen click lol. No clue what it is any when I went in to change my tires out at the dealer, it wouldn't happen while trying to show them.
