Thank you! I pressed around and low and behold, “Click” near the passenger seat area back a bit from the sunroof. Drove today on bumpy roads and no noise. I think this may be it! Will continue to evaluate for noise tomorrow, but pretty confident we can cancel our service appointment.There are some snaps in the headliner around the sunroof opening. Gently press against and around the headliner to see if any fasteners pop back in place. I had one behind and right of the driver's seat that snap back in.
