Service bulletins for the 2017 Subaru Crosstrek

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.

There have been isolated cases where the sealer used between the upper oil pan and the crankcase has become displaced resulting in engine oil seepage. Revisions made to the upper oil pan casting: * The mating flange thickness of the casting in the area identified as the cause for the seepage has been increased by 5.5mm. (See images provided in the Parts Information section below.) This thickness increase creates the need for a longer bolt to provide proper tightening and retention. * An additional mounting point has been added to the ribbing inside the casting to increase retention of the steel baffle plate and eliminate vibration.
