so after reading the first page, then skipping to the last page on this thread and working my way "up" until 2017 postings, Im a little concerned the sensors (13598772) I bought might give me problems, the serial numbers arent listed in this thread, but if I search for ACdelco 25920615 or just the number itself, it comes up as an interchange part.
Ill update once I can get them installed.
if possible, Ill have them check signal before installation onto the rims.

Update fixed it
So,
Out of curiosity this weekend, I went ahead and plugged the Matco MAXME scanner back in for a second. I went into the Tire parameters and found that the Tire Pressure notification pressure trigger (essentially you can control at what point the light triggers for low pressure) and the load rating of the tire had somehow been erased.
Once I told the ECM what the load rating and tire pressure should be......
THE LIGHT TURNED OFF. And is reading correct pressures for the tires at their respective locations.
What a shenanigan. (I think it truly was my fault being new with this scanner, and I must of erased the TPMS information at some time from the ECM).
Lesson learned. And thanks for the help guys. I hope my issue can help someone else later.

Last time my dealer rotated, I believe they went front to back (i.e. LF to LR & RF to RR) and criss-crossed rears to front (LR to RF & RR to LF), which appears opposite. Not criticizing method, only noting that ending tire position may be totally up to the company that did it.

Q: Do all Vehicles Have Tire Pressure Monitoring?
A: Starting with the 2008 MY, all GM vehicles sold in the United States are equipped with tire pressure monitoring, to meet the mandates of FMVSS 138. Some vehicles built prior to the 2008 model year or sold in Canada have tire pressure monitoring; check vehicle build and RPO information to be sure.
