I work at a dealership in the Service dept.
First off... nope... Have not encountered that concern yet.
The good thing is that its under warranty if they figure out whats going on with it. I have moved hundreds of these trucks around the lot and never had one look like that. Hopefully your dealer is a good dealer and works it out for you. The first guess would be what they said... that the radio needs a system update (which those radios get updated constantly by the way) So who knows... if you just had one done there might be another one out!
Good luck.. hope they get ya fixed up. They really are great trucks.
