Car is with the dealer. They suspect the plastic that covered the visors during shipping and pre-delivery may have caused the discoloration. They're ordering replacement visors. They don't see any evidence of water damage but my advisor will ask the tech if a water leak test needs to be performed.
Unrelated to the visors, but when driving this week, I noticed clunking when turning to almost full lock for parking. Service advised that there's a TSB out and will replace my front upper right strut mount...quick google brought me to this:
