Service bulletin 18-023-15 REV.C
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
Flash: 3.0 L MIL Illumination Diagnostic and System Improvements This bulletin involves reprogramming the Powertrain Control Module (PCM) with the latest available software. It also involves the cleaning or replacement of the Exhaust Gas Temperature (EGT) Sensor 1/2 and/or Catalyst Temperature Sensor if necessary depending on Diagnostic Trouble Codes (DTCs) that may have set. A small number of customers may experience a Malfunction Indicator Lamp (MIL) illumination. Upon further investigation the Technician may find one or more of the following Diagnostic Trouble Code(s) may have been set: P20C2-00 - Reductant Heater 3 Control Circuit Performance. P204F-00 - Reductant System Performance. P20E9-00 - Reductant Pressure Too High. P249C-00 - Excessive Time To Enter Closed Loop Reductant Injection Timing Control.
