It is a 2016 crewcab LTZ it has about 4800 miles it happened once before and self corrected but it has not changed this time.

Has the battery died recently and been changed out, has the truck had any dealer updates applied recently? After a battery change out or a calibration flash the temp will read wrong for up to a couple of hours.

No problem with the battery and no dealer flash It seems to have corrected on its own. Took it out today and everything seems back to normal.

Thanks for the replies

Did it happen to read 32 degrees? I've that happen a couple times. Once after I reconnected the battery as the above poster mentioned, but often after going through a car wash. I moisture can get in it, short it to read wrong, and then work properly once it dries out.

It wasnt 32 degrees it was 61 and the outside temp was 75 but stayed on 61. I did go through a car wash before I noticed the problem, maybe that was the problem.

Mine has done that a couple times over the past year. One time lasted for entire 20 minute trip to dealer. 75 outside, display read 57. Dealer checked calibration - no problem found. Did it again briefly a couple months after. No issue for past few months.

I have a 2015 2500HD Duramax LT Crew cab That I purchased factory towing mirrors to upgrade. I also replaced both dorr harnesses as required per the GM Parts Center recommendation. These are manual fold and extending. All my functions are working good except the outside temp reading on the Radio and Dash IP I get a "- -" in the temp reading area. No MIL codes are being set.

They sent a Authorization code sheet to have the systems flashed/updated.

I took to Dealer to have that done and they cant figure out why it does not work. The Mirrors do have the passenger temp sensor in them. The dealer does not seem to know what to do?? Can anyone help?
