Service bulletin TSB170098-011920

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 Technical Service Bulletin describes the release of a new fuel shutoff valve that are different in appearance, their electrical connectors are in different locations, and the connector pin shape is different. New fuel shutoff valves must be installed with the engine harness connector pointed away from the engine to allow the engine wiring harness to reach the new connector locations.
