If it Only had a Brain

A “small number” of 2014 Chrysler 300 vehicles equipped with a 3.6L engine and built on or before Sept. 27, 2013, may experience a MIL illumination, with DTC P0606 (internal control processor) in memory. This also affects automatic oil change indicator accuracy.

The fix involves reflashing, using software release 14.01 or higher. The software release also includes an accuracy improvement for the automatic oil change indicator system that allows the PCM to retain current usage/duty cycle information when the controller is reprogrammed.

Previously, the PCM would default to the severe duty cycle schedule any time the controller was updated.
