Took my truck to the dealer 2 weeks ago for issues with start stop and A/C they of course said there where no codes and nothing was wrong, well it was fine for a bit, now it has started again and with 2 additional problems, I have a check engine light, and the outside temperature sensor is all wonky or just blank, anyone have any clues? afraid the dealer is gonna tell me it is a computer issue since things are all wonky. I have a 2019 1500 bighorn with less 50k on it and bought it with less than 110 miles on it.

Definitely check for codes. Most auto parts stores will either check them for you or loan you an OBD2 code reader to check for yourself.

Do you know if the truck still has the original factory battery? If so you might want to consider replacing it, or at least have it load tested. Lots of people had issues with the OEM batteries, especially on earlier 5th gens. Weird things can happen once the battery starts to fail.
