The sensors on my '04 lasted until '22. Even then only 1 was bad and 1 other was weak (Denso sensors). Cold temps can weaken the batteries. Is the TPMS warning light solid or flashing? Flashing means you have a bad TPMS sensor. If one is bad you want to replace all of them at the same time. At a dealership it's not cheap.
If it's flashing you can find out which one it is. Start with the first tire and let out about 5 lbs. If the flashing stops and the light is solid, that one is working. Air it back to normal and go to the next tire. When you lower the pressure 5 lbs. and it continues to flash, that's the bad sensor.
At a dealership (or tire shop than can read Denso sensors) they can get a reading off each tire for the battery level, pressure and heat. I bought one for myself after having a shop replace all 5 sensors I bought off Amazon. A tire shop can replace with a different brand. I'm not familiar with newer T4R controls. The shop can update the ECU or you might be able to with your owner's manual.
