Service bulletins for the 2017 Subaru Impreza

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.

569 on file from NHTSA, as of 2026-10-19.

Bulletins, newest first
02-176-182018-07-16. Service bulletin. ENGINE AND ENGINE COOLING. This Service Information bulletin announces a design change to the upper oil pan baffle plate used on the models listed above. The new plate has a relief to allow for use of an oil level sensor which will be used in future production.
02-175-182018-06-18. Service bulletin. ENGINE AND ENGINE COOLING; EQUIPMENT. This bulletin announces a design change to the PCV valve used on the models listed above. Customers may have concerns of white smoke from the exhaust and / or in some cases, excessive engine oil consumption.
02-170-172018-04-02. Service bulletin. ENGINE AND ENGINE COOLING. This bulletin announces part information for new Active Valve Control System (AVCS) oil control solenoid valves (OCV) which contain a redesigned internal oil seal. The new seal will eliminate potential oil seepage into the wire harness connector portion of the valve. If oil seeps into the connector, over time, the Check Engine lamp may illuminate and set various AVCS-related DTCs.
02-166-17R2017-09-14. Service bulletin. ENGINE AND ENGINE COOLING. This bulletin outlines design changes made to the upper oil pan assembly on FA and FB engines used on the models listed above. 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.
