your are losing power DC12v to the cluster(loose fuse)
or the communications to it are bad.
check all fuses! cab/bay
and scan the OBD2 16pin DLC port near drivers knee's
scan it. using a scan tool. end guessing for sure COMM errors.
you can not fix modern cars lacking such a tool.
for sure EFI and all things in the car on the network.
USA car, not told. and cars are not the same all over earth. not yet.
seems like the IP cluster is not happy at all.
the radio uses the same Can_bus network ! hummmmmm
aka,. gM lan, or low speed lan
and pin 1 on the scan tool tool.
the cluster is digital and is called IPC,
scan the car,
or get it fixed in a real shop with real tools.
the SM is here
