I'm having similar issues in my new Sierra had it for about a month and once (5 days in) the speedo side went out and yesterday I went to the local waste transfer to toss some recycle stuff, shutoff the truck when I dumped the barrels got back in, and no maps, no carplay, and no ability to change radio volume via steering wheel controls. When the speedo went out I lost steering wheel controls on the right side also.
