My tire pressure light was on but got 4 brand new tires last week. Pressure light went off. But today it was back on. What’s up?
Have you checked your tire pressure with a gauge? Your car is eleven years old. Did you have the sensors replaced? If tire pressure is correct, chances are, if original, that is your problem.
^+1 for actually checking your tire pressure. You could have run over a nail or something. New tires can still be punctured.
