Any ideas what this creaking plastic noise might be on cold start? Gonna try to recreate it this weekend if cold enough and pinpoint where it’s coming from.

Could it be the front louvers doing their open and close sequence?

Active grill shutters maybe?
‘Possibly closing to expedite the engine warmup process.
