Thanks Rob22315 ...
I am doubting the TPMS system was properly activated/registered at dealer prep. That was my first theory. My car had just been delivered to the dealer the day before I purchased it. When the TPMS light came on at 20 miles ... I checked the tire pressure in all tires and all were approx 40 psi (cold tire pressure). I have checked and see where it is normal for Honda to over pressurized the tires for shipping. And from what I could see about how to activate the TPMS system ... I would have thought the pressure would have been released and each tire refilled to proper 33 psi.
I mentioned this to the service crew and salesman but they assured me that the proper pre-delivery service was performed. I don't care that they forgot to do it ... I just want it fixed. BTW ... after that, I got under the hood and checked to be sure I had oil!!

Thanks again.
