Did you physically check the pressure with a gauge or are you just going by
the way the tire "looks".
The light comes on when the pressure of the tire drops below 28 psi, when
the pressure is properly corrected the TPM (tire pressure monitoring) system
will shut off the light.
Please review your owners manual, it explains the system in good detail

Follow up-
I bought a new pressure gauge, rechecked all tires and verified 33 lbs
in each tire that my other gauge had also read. Light still on. Filled
tires to 38 lbs and light went off. Backed tires down to 35 lbs, will
see if light goes back on.
It seems the warning system may be faulty if it is only supposed to be
activated at 28 lbs or below.

Might be unrelated. But! At work we have a Dodge Sprinter with monitoring
tire pressure as well. In the owner's manual it says that you must not
change the cap on the tire valve from plastic to metal, as it may interferes
with the signal.
