Man am I glad I found this discussion! Picked up my refreshed '22 Duramax less than a month ago. Just rolled over 1k on the odometer before issues began. The only light I got on my dash was during inclement weather, so I chalked it up to obstructed sensors. But days later, I noticed to lane departure on the dash, or seat feedback, no adaptive cruise, and no automatic hi/low beams. I was going page by page in the owners manual to see if I missed something before contacting the local Chevy dealership, but I'm going to try the fuse fix on my lunchbreak tonight!
Thanks to Kaylan and everyone else for the discussion!
