I bought a 25 Laramie with everything but tech package about a month ago. Thurs when I left to go to work the screen said maps loading. I didn't think anything about it until the dash went blank a few minutes later while driving. It continued to do this every couple of minutes resetting the mileage back to 1615 on the odometer for mile 32 mile trip. Most features of dash would not work while it was up. When I returned home it did the same thing but this time check engine light stayed on. Dropped it of at dealer yesterday and of coarse this was a new issue for them. Anyone had this issue?
