In the options on the radio is it selected?

You have to go to settings and turn it back on every time. Yes, it’s stupid.

I understand how it works, ive used t many times, it will not turn on, nor will the tpms warning light come on as it always has at start up. I run my tires at 55 (below the factory preset pressure)

It doesn’t seem like you understand how it works. It has absolutely nothing to do with the tire warning light.

Selectable tire fill assist is to help you inflate your tires. Read the manual.

Ok

Get a programmer like Alpha OBD and change the low pressure warning threshold to a lower, more reasonable setting. I run 35/30PSI on mine and set the warning at 20 PSI.
