Can the valve stems be replaced without having to buy a new pressure sensor as well? Or are they a unit?
Had to put some air in the tires the other day and noticed the stem cap on the driver side front was really hard to get off and put back on. It also doesn't seem to want to inflate like it's clogged. Thinking about taking it to the local tire shop and having them replace the stem on that tire.
But don't know if I have to buy a whole new sensor along with the stem before I go to the tire shop.
If you have the OEM sensors, they are one solid unit. Remove the valve stem insert and install a new one. Hopefully, that will fix the issue. The stem caps can be easily be replaced with new ones. The cheap metal caps that come on the stems are easily bent, thus hard to remove and install.
I stopped using metal stem caps. They can corrode underneath and virtually weld themselves to the stem. When that happens removing them will often destroy the stem. Then you're left stranded.

I put a very small coating of Curtis red grease on the threads, no issues so far on my 13 GS.

I was at the tire shop this morning getting a flat fixed on my Sorento, but while I was there I asked him about replacing the stem insert so that I don't have to replace the whole sensor, and he made it sound like it can be a real pain and sometimes ends up needing to replace the whole thing anyway. Is this something I could do myself in my driveway? Are the stem cores vehicle specific or can I get any stem core?

Do you have a compressor and floor jack/jack stands at home ? If so, you can jack up the wheel with the "bad" valve stem core, support it with the jack stand, then remove the core. You can then go to your local parts store and match up your old one with a new one, replace it and reinflate the tire.
C6 tpms, and yes, the stem part of it, is part of the sensor unit.
the other parts that seals off the stem to the rim.
As for replacing a TPMS, just need to break the bead on the tire to push the TPMS out (into the tires once you have remove the outer barrel nut with seal), and then install the new TPMS from inside the tire, add the outer seal and barrel nut back on to tighten them, and most of the time don't need to re-balance the tire. But since it may have been a while since the tire was last balanced, may as well do it while the tire is off the car.
Myself, since I like to have the tire road balanced, may as well just remove the tire, replace the tpms and remount the tire, do a quick spin up of the tire and rim to see if the tire needs to be rotated on the rim to begin with to index them correctly from the start, then the final spin up with road balancing weighting in the end.
Hence tires last about 5 years before the the rubber gets hard, most sensors are questionable in battery life during the tire replacements as well, so may as well just spend the $100 to have the sensor replaced when you are replacing the tires every 5 years as well.
The outer stem is replaceable also. TPMS/24-7 offers your choice of metal or rubber stem. They are separated by the removal of a small hex head screw in the sensor. However to do this the sensor must be removed.

It's not metal that is the problem, it's the dissimilar metal that can be a problem.
