Mine comes on periodically...not sure how often but as soon as I touch the gas it disengages so it shouldn't be a problem. And to the guy that says ALWAYS use your parking brake, in NE Pennsylvania where winters can be very cold and damp I was always taught NEVER to use the parking brake because it can freeze and be a real pain to release. You can sometimes put in reverse then back in drive, all depends on conditions. I'm 4+ months in with a '20 AT4 and LOVE, LOVE, LOVE this truck.
