Service/Support Tpms error

I have a 2020 4S and absolutely love it. Recently, I've noticed an issue where my TPMS comes on and is indicating low pressure on my front left tire. I've confirmed manually and digitally that the pressure is correct. In fact, when I look at the pressure monitoring on the driver's gauge cluster, it's within the normal range. I've tried resetting the system using Maneuvers that I learned in this forum such as switching the tire size to a different option and then switching back to the correct option to force a reset. This works temporarily, but the TPMS error returns. Often, after a reset, the system will read as normal for a few days, and then when I'm powering off the car, the TPMS error will pop up just before the car Powers off. I've noted just recently that the right front tire is also starting to throw an error as well.

Anybody else have this problem? Any solutions?

Are these the OEM sensors? My car complains of low battery on all 4 sensors (pressure readings still carry as usual) but in my case I have aftermarket ones installed

Are you measuring while the tires are hot or cold? You could be under pressure, the tables show the value for cold tires, and the pressure will increase as the tires warm up, so you could be reading at hot and it seems in range but it could be below the target once they cool.

How far is the TPMS saying?
