2022 1 ton dually 6.7 ho. I keep the main dash guage on fuel economy/ mileage. It’s been flickering between that & 4wd in process, & service electonic stabilizatio control. Acts like a loose connection ? Flickers back & forth. Mostly when im on longer drives ( 1 hr or more) but not always. Anyone else experience this. It’s still under warranty & have an appt at dealership tomorrow. Any insight would be be appreciated. Tia
