2021 Colorado ZR2. At around 18,000 miles this started with me as well. Very similar as Kachup mentions above. Getting a Nav SD Card error code of 0x40000.0x.0x.5079.0x I have a call into the dealership.
update 3/26/23: Dealer stated first step was swap map SD card. They did, same issue post card swap. Next step is to leave with the dealer to do additional troubleshooting.
