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.

Actually Busdriver hasn’t answered the question as to where the key fob were when the truck started on its own. The signals from the key fobs are coded so likely accidentally tapped the fob in the pocket.
Someone mentioned leaving to hood open, I had a failure to remotely start the other day I had put some stuff in the back seat, and had not gotten the door fully closed. I do know that if not all doors are fully closed when driving, not only do I get the little icon on the instrument panel, also the interior lights stay on. Not sure if they would time out if truck not running.
