"Remote not detected Press brake to start car" message when turn off engine

What is your question?

Sometimes the message "Remote not detected Press brake to start car" comes on after I've been driving, parked, and turned off the car. It beeps if I open the door, so I have to restart then shut off the car again to clear this. Any ideas?

How long has your 2016 Buick Regal had this problem?
