While driving the vehicle, the TPMS light would come on and go off sporadically. We stopped at a local gas station to check the pressure and all the tires had adequate pressure. I had the tires balanced and rotated to see it that would correct the problem and had the front end aligned. This still did not correct the problem. Finally fed up, I took the car to a local Firestone to have them check the system. Firestone changed the sensor on the front driver side. When I left, the car was fine, no errors. On my way to work on the following day, the light came on again. I returned to Firestone and this is when they shared with me that the sensor that was bad was not the one that they changed, but the one in the rear. As a courtesy, they changed the rear sensor free of charge. However, the reading on the car was still faulty. By the time I got to work, thirty-five minutes later, neither of the sensors that Firestone changed were reading by the car. The tire pressure for both tires read --. I called a Chrysler dealer in Tacoma to have the car checked out there. I did not tell them that I had two sensors changed already because I wanted to know what their diagnosis was on the car. Ironically, they said that I needed four TPMS sensors and it would cost $900. When my husband told them that I"D already had two sensors replaced, they came back saying that either the work was not done correctly or they did not recode the sensors to the car. My husband then took the car back to Firestone;Firestone put four brand new original Chrysler TPMS sensors on the car, free of charge. The sensors still were not reading. The Chrysler service department had him bring the car in. They cleared the codes " the car was fine for a little while. Before I was off work, the sensor on the driver front was again reading --. the code will clear itself, then come back on.
