I guess I am lucky as my husband put on the snow tires from my former SC400 for this winter (no TPM in those wheels) [just got the new SC430 this month] and can't see spending a lot of money on new wheels and snow tires 'til I know exactly what I want and get a better feel for the car] AND there are no bells or lights flashing.... the car originally was built in Oct 2009 BUT not bought until June 2010 and had been driven only 16,000 miles and I was told has the original wheels/tires on it when I purchased car. Maybe 1st owner disabled already. I guess I've driven cars without TPM's my entire life and lived to tell.... so.....what's so special about having MORE technology that simply looking and checking your tire pressure regularly can't do?

I suppose your last statement is the issue, i.e. owners/drivers actually taking the time to inspect their cars BEFORE driving, especially when conditions are not at there best for driving. We saw a lot of this in the late 90's with the Firestone-Ford rollover fiasco. Even through TPMS devices were available in expensive European car, or higher end sports car in the late 80's, U.S. manufacturers did not include them until the US Congress passed the THREAD ACT in November 2000 and they were required to do so (part of the ever growing nanny state we live in today).
Our TPM system only warns us when the tire has lost approximately 20% of the inflated high mark. Somewhere between 4 and oh 8 lbs of pressure.
While I understand why some have decided to disconnect their TPMS device, IMO it's a bad decision to disconnect and safety system required by regulation.
I hope you discover yours is working properly and the previous owner did not disconnect it without telling you.

Did you buy the car from a dealer or an individual? If you got the car from a dealer, bring it up to the dealer and ask them to rectify it.

BTW, welcome to the forum.
