Should be able to pull the code from the dash. Should be a procedure in the owners manual. Pull the code and post it on hereI've also had check engine light come on 2 times. Shut it down and restarted 2 'in later. Still on. So I drive slow back to truck and after 1 mile it turns off. Talked to dealer - but they are clueless. It's so new they have no idea what the hell to do.
