After downloading the full Service Manual (yes all 12,674 pages), I was poking around and found in the "LIGHTING SYSTEM > Headlight Assembly" section... The High Beam, Low Beam, Parking, Side marker, and DRL bulbs are not replaceable and are all integral of the Headlight Assembly.
Looked online and it appears as though the Headlight Assembly is over $400.
So... Any one of those bulbs go out it looks like a trip to the dealership for some of us and at least $400 for all of us. Very disappointing evolution.
