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.

Certain vehicles may have a condition in which the high-pressure fuel pump may crack and potentially leak fuel. This may occur over time with vehicle usage. If a fuel leak occurs, the customer may notice an odor. If the fuel leak is unaddressed, the vehicle may fail to start, exhibit reduced engine power, or lose propulsion. This will display a message on the Driver Instrument Cluster and illuminate the Check Engine Light. Dealers will replace the high-pressure fuel pump and insulator. |
