2018 3500 SLT Outside temp. stuck on 13 degrees

[JohnDD]

My new truck has an issue with the outside temperature value, it is stuck on 13 degrees. I read some other posts that said this may also affect the way the air-conditioning works. Has anyone else had this issue or know of it? My next move is to go to the dealer but would like to hear if this is a one off or something that is ongoing.
