Excessive Icy Conditions Possible Messages

[Mathew Kirsch]

When my 2015 Silverado 1500 was new it would show the "icy conditions possible" message at 33F, and ONLY at 33F, and then only once shortly after the truck starts moving.

 

Recently it has started showing the message regardless of temperature, and it seems like it shows it again any time the temperature changes a couple of degrees.

 

I've gone to calling it the "No Sh*t Sherlock Warning." It's winter. Duh. It's cold. Duh. I know the roads can be icy. Duh. You never nagged me about it like this, stupid truck. Give it a rest!

 

Is there some way to change the behavior or even turn it off?

Both my 2015 and my 2018 come on with this message every time its around freezing.  Probably something in the PCM/BCM that might be able to be changed to stop it but no idea if anyone has found a way to reprogram it to turn it off.  I just ignore it, especially when there is 10 inches of snow on the ground like this morning.

That's how mine USED to work. I'd get the message at around 33F and ONLY around 33F, ONCE, when I first start the truck. If it was below freezing, I would not get the message.

 

Now I get the message CONSTANTLY. 33F - message. 26F - message. 19F - message. 12F - message. 4F - message. It comes up multiple times during an hour of driving. Every time the temperature changes... ICY ROADS BLAH BLAH BLAH!

 

Something is different. Something has changed.

Maybe the outside ambient temp sensor is going wonky. Other than that I have no clue.
