I’m not sure if has to do with the TPMS or not. The tires are within the normal range I set on the tazer mini. It flashes and beeps, then goes solid when I go into drive. For some reason I thought I read something on here about this being related to a separate issue. I recently drove over 2400 miles and had no problems.

What were the individual tire pressures when you manually checked them with a tire gauge?

------------

Per the Owner's Manual, that "warning light switches on and a message is displayed to indicate that the tire pressure is lower than the recommended value and/or that slow pressure loss is occurring."

Can't you scroll through the dash menu via steering wheel buttons to see if any messages are displayed? The pic looks like you have that option.

JL‘s threshold comes set from factory at 35-37 PSI, depending on trim and tire configuration. The TPMS will warm you when tire pressures drop below the preset.

You can lower the thresholds with a Tazer. Now that I roll on 35s I have mine set at 30 PSI.

set the tazer lower then
in the cold the tires lower pressure triggers the light and on the newer mopar vehicles it never shuts off until you inflate them to factory spec or higher

Lol. Based on what? I would argue that is too high for me. I run mine at 32 after chalk test. The OP didn't even say what tire they're running.
To make the light go away.

I’m running 37x13.50r20 Nitto mud grapplers. I’m pretty sure I set the TPMS to come on at 20 psi. This is a 2021 JLUR, not sure that makes a difference. I’m wondering if the Tazer settings got messed up somehow. I did not change anything. However, I am in 82 weather now vs 20.

When I lost pressure out of a tire in the past, the cluster indicated which tire it was. None of them are showing red.

Oh, lol. Iiiiiiiiii'm dumb. Mine hasn't been default for so long I forgot it was ever that high. Lol
Yep. They’re set for fuel economy. I prefer mine set as low as possible, so the light only comes on when I have a dangerously flat tire.

You should check your evic for messages. I get a TPMS message after rotating tires, usually goes away after 100 miles or so. If its a low tire, your right, mine shows the tire in red.

I have not checked them with a manual gauge yet. Just going off the dash reading right now. I will check them tomorrow with a gauge and see. Like I mentioned earlier, I don’t understand why the light and sound indicator is on and the dash reading shows all tires are good (not red).

This is why I am wondering if something else is going on.

I guess the other option I have is to air them up to 37 and see if it clears. Then I will know the Tazer setting somehow bumped back to default.
