car signal on the dashboard did not appear when my rear tire was running flat
My car has 30800 miles.
My car has an automatic transmission.
Your car has sensors at each of the four wheels that monitor the tire pressure at each tire. When these sensors fail, you may notice inaccurate readings as to your tire pressure. In some cases such as yours, you may not receive any kind of indication. I would recommend having a professional from YourMechanic come to your location to diagnose and inspect your tire pressure monitoring system.
