No low tire pressure warning

[Tmdarkansas]

I just got my car last week and it has 12.1.2 on it. Unfortunately, I've already had to get a tire repaired because of a nail. I never got any low tire pressure warning from the car. I just happened to see the low tire pressure on the screen that shows all the tire pressures. I was only on that screen because I was showing people the car.

Has anyone else had a problem like this? What's the warning threshold?

You definitely should have gotten a warning at 33 psi. I believe with 12.1.2 you can now reset the TPMS. Once you have all tire pressures correct I would try the reset. Then I would lower the pressure on a tire to verify if you get a warning. If you do not I would notify your SC.

On some cars the warning comes on when pressure is 25% down, so at 33 it might be right on the borderline. Let a bit of air out and see if the warning comes on.
