RE: TPMS sensor alert.
Not sure where you are located, but I've seen in different vehicles when the pressures are set at 32, and you get a cold night, science takes over and you can "lose" a few pounds which will turn on the light. After driven and warmed up, the tires "make" more pressure, and the light will go off. If it was on a cold morning, you can set the pressures to 35 with no issues, if it was while it was warm, you may have a sensor going bad.
