2013 JK - Temp gauge stuck low?

Usually my gauge reads 1/2 after 5-10 min of driving.
However, on my 30min drive to work, the needle stayed at the lowest reading. I definitely had heat and seemed to be operating like it was at normal temps.

I turned the jeep off after parking, and restarted it, the needle went to the middle, proper position as if nothing was wrong at all...

Why would this happen? It's as if the ECU didn't like the signal coming out of the temp sensor when it was started and decided to cut it off for the rest of the ride. If that's the case, what would cause the sensor to go wacky? I had the block heater plugged in last night and this morning was -18C / 0F - could it have been the shock/differential in coolant temperature once it circulated through the block? Making some crazy guesses here.

I've been strapped for time lately and don't really want to take it to the dealer right away if it's something that can wait until the next major service.

Wait and see if it is a recurring problem. It's possible it was just a fluke. If it continues to happen, then I'd look into it, otherwise forget it.

Yeah I guess so, It's hard to take a problem to a dealer that I myself can't reproduce consistently
