Service bulletin TSB180071-082120

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 (TSB) describes the verification and resolution of the fuel pump actuator housing and fuel pump actuator - air bleed check valve becoming contaminated with debris. Debris accumulation prevents fuel flow to drain resulting in possible external fuel leak, loss of fuel pressure during motoring condition, Fault Code (FC) 559, FC 4691, crank no start, and/or shutdown. This TSB describes how to properly repair the failure; the cause of this failure will be addressed in NHTSA Recall 18E-081.
