Took delivery of my MY22 in Nov after waiting 11 months and my dealership said they ordered the missing vents that same month. The last time I reached out to my dealer for status was early Jan and the reply was "ordered, no ETA and we will call you once we received them".
I emailed my dealership today asking for status and all of a sudden they arrived. I doubt it was perfect timing so who knows how long they been sitting there. I am going in Wed for the install, so there is hope for those still waiting.
