Service bulletin Circular24GAREV1
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
This action addresses an emissions system-related Engine-Off calculation error and improves the Oxygen Sensor Aging-Correction Factor. Neither concern has a direct impact to vehicle exhaust or evaporative emissions. However, either condition could affect proper operation of the Malfunction Indicator Lamp (MIL). Problem description updated.
