I have this same I'm having this same exact issue with my 2023 AT4 (3.0L). I have around 500miles on the truck and my DEF indicator in the truck is only down one line from full. However, my MyGMC app has been showing DEF Range Low since a week after I got the vehicle. Everything else in the app seems to be working fine...sometimes my PSI might be off by 1 or 2, but no biggie. GM tells me the DEF Range Low issue is an OnStar issue since only my app is giving me false info. OnStar has elevated my complaint like 5 times now and gone through diagnostics over the phone with me like 10x. I don't know if its an app issue or if there is something within the truck that isn't feeding correct info to the app, specifically the DEF Range. I want to clarify that I don't get any warnings or popups in my vehicle cluster or dashboard...the ONLY issue is the app reporting DEF Range Low.

I will have to look into this!

See you later alligator!

Hahahahha. I’m on a phone so none of those suggestions apply. I e already started bitching, just not on here yet! It’s tough to find screen real estate on here to spend much useful time doing anything. LOL

Hi all! I am not sure who to address this to, but I was REALLY hoping that someone could add more pop up ads and video ads to this site! I’m only closing like 4-6 pop up videos every time I open a page on here. That’s ridiculous! You could easily double that number. Laziness. Having to close 4 pop ups each time I want to read a comment is so satisfying. I especially like the ones that just overtake the entire screen every so often. More ads please!!!
