I have a 2016 GMC for the last year on occasion my stereo doesn't work properly until I shut the truck off for a minute or two. Now today on start up I received every dash warning that I believe there is The gas gauge goes to empty, the batt. light comes on, the airbag light comes on and the abs along with the brake light the speedo doesn't work the tach didn't work the odometer didn't work. I stopped to put fuel in and when I started again everything seems to be normal. My mechanic said either a ground of ignition switch because it is on start up I am thinking ignition?????
