I bought a used 2007 GS350 about three months ago. The car has been great and have had no issues. On the way home for Thanksgiving the check system light and tire pressure light came on in the car. I pulled over at the first tire shop I could find and had the tires checked. The mechanic said everything was fine. I then took the car to the Lexus dealership to get checked out. The service tech informed me that there were no TPMS sensors on my car.
My question is how have I had this car for 3 plus months with no sensors and the warning lights just came on now? Is it possible that someone took out the sensors and overrode the system to not go off? The sensor on the spare is even missing. I am clueless. Any thoughts?
