I had to reset mine only once, the day after I picked it up. I'm at about 2700 miles.

 

Feeling extremely lucky (knock on wood) because the EXACT same thing happened to me. I checked the tire pressure and reset the thingy and it hasn't come on since, that was over 3k miles ago ... I really feel your pain because my old car (02 Civic) gave me nothing but headaches and random lights, sucks when your new car starts up with that too.
