I have a Toyota Matrix, and every fall when the temp starts dropping, i get this warning on my dashboard. A quick tire topup with air and the warning light goes away.
My Odyssey did that. First time in the fall, but only a mile from my house. Then you get the lump in your throat and the "I just ran over a nail" thought. So you pull over and bang on the tires and find they're OK and drive the remaining 40 miles to work. Driving home in the afternoon at warmer temps the light goes out and you forget about it until the next morning.
Rinse & repeat.
