HAD CAR IN FOR OIL CHANGE AND ROTATE TIRES. next day light on dash for low tire pressure on-went back they rechecked air pressure all still okay. They reset the signal and all okay for a day then light back on. They say air pressure still okay and said this model does not have sensor so not a sensor. I don't know what else as light back on today after recheck tires and reset light for second time Monday.
