Over the summer the light came on, no sounds air pressure was fine. Turns off everytime I turn the car off and comes back on about 20mins into my drive. Sounds like the same problem everyone else has. Had new tires put on this last weekend and The guys at discount tires said all the sensors come back with good readings. I have a half day friday so I'm gonna stop by there as the light will turn on by the time I get there and maybe they'll see something different if the lights on. Trying to avoid going to the dealer.
