Going back to your original post. It might have been asked but never answered. Do the dash lights all flash if you use your remote and start the truck?
If yes the dash lights all flash I would suspect you accidentally started it with the keys in your pocket.
If no the dash lights do not all flash then I would go back to the dealer with it as something is not right.
