Advanced Diagnostic Warning Flat tires

[MTY55]

Has anyone else seen this lately. I seen a post on the Sierra Owners FB group. This morning I received a text and email stating this.  I know there were no flat tires because I was driving. when I stopped I checked the DIC all tires were @35lbs. I just did a software update the other day this may be a glitch. Update GM N23-241156

I also got this text but my tires were low after swapping my Duratracs from a 21 Trail Boss to a 23 T.B. My dealer had to replace all 4 tire pressure  monitors for the 2023.

Factory pressure is 41psi cold. I'm not sure exactly at what PSI they set the low tire pressure warning.

Yes same here.  Alert on phone @ 4:45 AM.  Truck parked in the garage and the Chevy App is showing four flat tires. All were at 38 psi.  Just did the update day before yesterday, so more electronic glitches.

Different models have different psi.  This is my truck.  2020 Trail Boss LT with 18s.

Btw, if you look at the myChevrolet app you'll see this if there's a problem.  Looks like I need to talk to my wife, and do a little refresher with her.

The My GMC showed basically the same as your Chevy app but the right rea was 31psi. Abut a half hour after I got the bad tire pressure I received this
