SUBJECT:

NUMBER: WUS-04

2017MY Impreza

DATE: 10/24/19

PCV Valve- Design Change

NHTSA: 19V-745
INTRODUCTION:
Subaru of America, Inc. (Subaru) is initiating a safety recall for certain 2017 model year Impreza
vehicles in which the Positive Crankcase Ventilation (PCV) valve may be defective. Please note:
while the reason and safety risk behind this recall are the same as WUP-01, this recall differs in
the work process and remedy. Please confirm the vehicle is under WUS-04 by using the Vehicle
Coverage Inquiry before proceeding further with this bulletin procedure.
AFFECTED VEHICLES:
Model Year(s)

Carline

Production Date Range

2017

Impreza

May 11, 2016 – November 11, 2016

Not all vehicles in the production range listed above are affected by this recall. Coverage must be
confirmed by using the Vehicle Coverage Inquiry function on subarunet.com prior to repair.
The status of this recall will display as “Open – Remedy Not Yet Available” until sufficient parts
supply is available.
REASON FOR THIS RECALL:
The PCV valve may separate and allow engine oil to enter the combustion chamber, resulting in a
visible change in appearance and/or the amount of tailpipe exhaust. If driving under this condition
continues, separated components from the PCV valve may enter the engine.
SAFETY RISK:
If separated components from the PCV valve enter the engine, the vehicle may experience a loss of
motive power, increasing the risk of a crash.

Service Bulletin applies to your vehicle, or that your vehicle will have that condition.
