So, I have had my first tire puncture with the FiST. Looks like it was a nail / screw that caused it. Was a mile or so from home when the dash light came on. Made it home, opened my door, and heard the hissing. With 3300 miles on this car, I think it is cursed.

Don't get too giddy over the success of the warning, it doesn't always work as intended. When I first bought my 2011 Fiesta, I drove around for three days (unknowingly) running eight pounds low in all four tires before the warning turned itself on. The dealer apparently had a bad pressure gauge, because even the spare tire was eight pounds low.

I suppose you could say that the system can be a life-saver, when it works, but this incident taught me to not rely on the system exclusively...

I don't rely on it. It is supplementary to my ears and eyeballs.

TPMS is awesome. Eyeballs cannot "see" when your tires are 3 psi low like they were when I was driving home from disco tire and the low pressure warning lamp came on. They inflated my tires to 32 psi because they thought my Fiesta was a Focus. The 2011 Fiesta with 16" wheels needs 35 psi.
