The issue is clearly an electrical glitch. There's no way coolant changes temp that fast. A simple gauge like the Torque App can show the coolant temp at the ECU in realtime. Viewing what's happening with the coolant gauge while seeing what's being reported coolant temp could probably answer a lot questions.

My guess is the gauge cluster is the culprit.
