Sounds like the BCM lost the programming for those lights, that’s why is is so important to have a good battery or a battery tender if it going to be sitting for a while and a memory saver tool for when the main power is going to be disconnected for a while. So now you will need the dealer to re- flash the system to bring everything back up and running.
Take it back to the Dealer. Let them fix it for free under warranty. Hope that helps! Jim
