Nitrogen makes sense. Doesnt expand and contract with air temperatures. I guess it could be a problem if you were constantly airing down and up but I can see the positives out weighing the negatives.

There is a procedure on this site that explains what you need to do to reset the TPM system yourself. You flick the headlight switch, and then let air out of each tire in a specific order, and the system is reset. If you can't find it, I'll post it later.
But the root cause is, either you have one or more sensors needing replacement (they are battery driven, but the batteries can not be changed, you have to change the sensor itself) or you're low on air. It is plausible that the cold weather reduced your tire pressure. You should check your tire pressure regularly regardless of what the TPM system says.

Funny, been driving me nuts for about a month and a half now too. I got new tires put on a few months back and they changed all the TPM's so I assumed it was a bad one, but i guess most likely from the cold temps. Thanks

ive had 2 diff h3 thru 2 winters below zero, hot summers.
so far i had ONE tp warning, on a nice day, when i had a slow leak. got it fixed,warning went out.
never again, they seem to work flawlessly. batt? 7-10 yrs?

You guys with all the "problems", what is your tire PSI?
Set them all at exactly 38 cold.
BTW the spare is not monitored, an H3 can only monitor 4 sensors, so unless you have a spare that was one of the original 4 on the ground, it is out of the loop.
