Service bulletin N212336951

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

Emission Recall. On certain vehicles, The Vehicle Emissions Control Information (VECI) label may not contain the correct OBD (On-Board Diagnostic) system identifier. Since a new label can be easily installed, and to reduce customer inconvenience, the label will be sent directly to customers of record along with the installation instructions. Customers may install the label or, if they desire, they may take the label to their dealer for installation at no charge.
