Did more research on this and if you have verified that there are no actual leaks in the tires. It sounds like the TPM module may have failed.

The Universal Garage Door Opener/Tire Pressure Monitor odule is located in the headliner near the inside rear view mirror. The Tire Pressure Monitoring (TPM) system utilizes a control module to monitor and operate the system. The control module also has a universal garage door opener integrated along with it.

The tire pressure monitoring system utilizes transmitters that are located in the valve stem of each tire to communicate the tire pressure condition to the module. If a tire has low air pressure, an indicator light on the Instrument Cluster is illuminated. The vehicle operator must check the tire pressure of each tire in order to determine which tire has a low pressure condition.

The TPM and UGDO are not serviceable and if one or the other fails the entire unit must be replaced.
