There is a Technical Service Bulletin (TSB) for your vehicle stating that if the light is blinking and if there are dashes (- -) on only one or two tire pressure readings, then the tire presure monitoring system should be put through a "Relearn" or "matching" process. Then if any of the tire pressure sensors do not respond while relearning, the sensor in that tire should be replaced.
The TPMS matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to ON/RUN with the engine off.
3. Go to the TPM vehicle information screen on the DIC. Press set to relearn the sensors. The horn sounds twice to signal the receiver is in relearn mode and Tire Learning Active message displays on the Driver Information Center screen.
4. Start with the driver side front tire.
5. Remove the valve cap from the valve stem. Activate the TPMS sensor by increasing or decreasing the tire's air pressure for 10 seconds, or until a horn chirp sounds. The horn chirp, which can take up to 30 seconds to sound, confirms that the TPMS sensor identification code has been matched to this tire position.
6. Proceed to the passenger side front tire, and repeat the procedure in Step 5.
7. Proceed to the passenger side rear tire, and repeat the procedure in Step 5.
8. Proceed to the driver side rear tire, and repeat the procedure in Step 5.
9. After hearing the confirming horn chirp, for the driver side rear tire, the horn sounds two more times to signal the tire learning mode is no longer active. Turn the ignition switch to LOCK/OFF.
10. Set all four tires to the recommended air pressure level as indicated on the tire and loading information label.
11. Put the valve caps back on the valve stems.
The tires air pressure will not appear on the screen until you start driving the vehicle.
Hi!
the missing tire is the bad one I would think. But If i were you I wouldn't touch it. I would only go back to the dealer and ask about it, Because your car is still under warranty. Good luck
