I'm buying an '08 Panel tomorrow, and it has one bad TPMS sensor. Should I just replace the one, or will the others likely die soon enough anyway that I should just replace them all?

The typical generally accepted life expectancy of the sensor battery is roughly 5 years.

If you don't know how old they are, or know if they have already been changed previously, it's up to you to figure out if you want to spend the $'s and just replace them all.

Personally I would just replace the one. All four of mine are going on eight years. Knock on wood.

I would wait until I need new tires and do all of them.

Have you tried resetting the positions?

bought the car yesterday (and love it), and I suspect they've all gone. When I'm flipping through the info view, there are no pressure readings. The previous owner didn't like TPMS systems, and just put a sticker over the light. lol

You could threaten him with legal action. The TPMS is safety equipment.

The guy was super nice. Besides, I offered $500 under what he was asking, in part by saying I'd take care of the tire sensor(s).

Anyway, I had them all replaced today for $50 apiece.
