Whenever I get new tires, they "rebuild" the sensors, which is basically just replacing the seals. They run on batteries, batteries don't last forever. I would be willing to bet, especially since its an 07, that batteries are the issue. New sensors are about $40-45 a piece.

I just let the damn light stay on, not hard to figure out if there is air in your tires or not...

The 07's don't do that, I wonder whether that started in 08 or 09?

You can look at the tire, or use a pressure gauge. People got along fine for over a century without tpms.
