TPMS indicator won't go away

It is a little early but one of your sensor batteries might have died. Best Fix is a black piece of electrical tape to cover the light. Making the sensors non serviceable is a CRIME!

have you recently got tires installed? It possible could be a broken sensor but its best to check with techstream to see which sensor isn't responding

 

I would just ignore the light till your next service, have them check it. Don't bother with tape, it could gum up the display bezel.

I look at that light for at least 4 months per year (with snow tires) don't even notice it after a while.

 

The problem is cost at the dealer for repair or new TPMS.
It only takes a few minutes for the TPMS signal to reach the car, so the light indicates either you have one TPMS not working, or the codes are set wrong (if you swapped in a new TPMS unit in a snow tire or something like that).
They say 7 year life but my first one died about 9.5 years and the other 3 going into 11+ Years now.

 

I don't offer this as a solution to your problem, but 20 PSI for your rear tires is pretty low. Very low.
I'd check your rear tire pressure, make sure you don't have a problem with them.
How often do you check your PSI? What PSI do you keep your tires at? 20 PSI rear is IMO way too low. Surprised you drove too long with the PSI that low without the TPMS illuminating.

 

20 psi usually indicate a nail in the tire, I would inspect the tire for nails. I had a nail in the rear tire before and within a month, it dropped to 20 psi only on that one tire. I knew there was a nail and the tire light was on when it was at 20 psi. I got the tire patched up and the tire light went away afterwards.

 

By the way how many miles on these TPMS?....miles driven is one variable in TPMS life as the battery stays on while the car is on. I am at 165k miles and 11 years with 3 of 4 orig TPMS still working

 

As others have said, 20 psi is very low considering the others weren’t as low (and also taking into account they were filled properly last time). Sometimes a sensor needs to be “woken” back up. Fill the tire to 60 PSI, roll the car a little bit, and then return to your preferred pressure.
