Yes. Cam phasers were updated in production 07/2018. The roof opening panel rattle is the result of a lack of lubrication and is easily corrected. That shouldn’t be an issue on a brand new vehicle.
As @smurfslayer said, the dealer is instructed not to update any vehicle modules unless directed to do so by a service message/bulletin or the Workshop Manual.
Thank you for your response. I appreciate the insight you provide on this forum (I'm new, but I've been reading a lot). My plan on the moon roof is to exercise it at least once weekly and lubricate it regularly (maybe monthly?)
On the software updates, I interpret your comment and others as saying, "The software it has is the software it has, and until you have a problem, the dealer isn't gonna update it or even look at it." Is that an accurate take?
