Service bulletin 511946B
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
According to FCA recall 25V330: "The Security Gateway Module (SGW) on your vehicle may prevent some communication between vehicle modules, which may result in the rearview image not displaying in a backing event. The vehicle operator may notice that the rearview image is not displayed if attempting to reference the image while backing. A rearview camera image that does not display reduces the driver's visibility of what is behind the vehicle and if not heeded, increases the risk of a crash."
