Check your fuses for instrument cluster.

It Sounds like an Air lock in the cooling system that's stoping the Temp Gauge from responding to the coolant that's not making contact with it. I believe (unless it's a serial failure from the BCM, in which case swap out either the BCM and the IMC) that it could be co-incidental and a sending unit failure inside the tank is at fault. This would certainly be less expensive than swapping out and reprogramming the Body Control Module, or having a new Instrument Cluster replaced and reprogrammed.
