On this new of a vehicle, I would like to think the BCM is still good. Have you tried scanning the CAN BUS system to see if there are any codes related? CAN stands for computer area network. All modules are tied together via a few wires.
Here is a video showing what I'm referring to:
Also, have you checked to see if there is power to the light itself? There could be an issue with the socket. Also, conform there is continuity to ground from that light socket.
I attached a pic below showing what I am referring to. Check those things and let me know what you find.
