2012 gs tpms
So my TPMS light came on the drivers side rear tire, checked the pressure and all is good. I suspect a defective sensor or dead battery.
The light has since gone out.
Should I replace all the sensors at the same time, I’m thinking yes.

2012 model year?
Most wheel sensors last many years longer.
In your case, perhaps the sensor was damaged recently, or even earlier from a tire change?
I think I'd see if the issue reoccurs, maybe even reprogram the sensors before replacing.
And I would only do the one wheel if the problem persists.
That's my two cents, good luck.

Find a tire shop with a real TPMS tester.

Could be just a gltich in the RCDLR programming from say a weak battery that caused a power dip in the RCDLR to loose some of it programming.
So easy way, check the TPMS to see if the battery is still good on it.
Attachment 48333004
Note is you suspect that the TPMS battery is going dead, but get a normal reading on it from the first reading, re-trigger the TPMS over a half dozen times to take repeat readings, and make sure that the battery is still coming back with a good/normal reading.
And if the TPMS comes back as good (normal in the above photo), disconnect the battery to reset the modules in the car (RCDLR being one of them) for about 10 mins, reconnect the battery, re-index the windows and reset the time on the radio clock, then just put the car into TPMS relearn mode again to fresh program the TPMS back into the RCDLR.
As for if the check ends up with a weak/dying battery in one of the TPMS, then with the age of your car, would just replace the entire set of TPMS with new OEM units isntead. Hence the OEM/Schrader units tend to have the longest battery life to begin with.

I went to the shop today, and on the way my pressure showed 30 psi in all tires. The warning light has been off a few days.
Well, they ran a diagnostic on the TPMS and said everything was normal and good. They couldn’t find a thing and the warning light is off and the tire pressure is fine.
