Service bulletin NAS19.12.010_2

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.

The root cause of the symptoms is the catalytic converter over temperature. The calibration of the exhaust sound tuning feature allows for too many repeated activations in a short period of time, resulting in catalytic converter over temperature and leading to Diagnostic Trouble Codes (DTC) P0420 and P0430 being stored in the Powertrain Control Module (PCM).
