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.

If a fluid leak is detected at the connection point of the delivery pipe, it is now possible to replace only the affected pipe using a dedicated repair kit, instead of replacing the entire engine compartment wiring harness.
