INTRODUCTION:
Subaru of America, Inc. (Subaru) is initiating a new safety recall for certain 2017-2018 model year
Impreza vehicles and certain 2018 model year Crosstrek vehicles in which the Positive Crankcase
Ventilation (PCV) valve may be defective.
AFFECTED VEHICLES:
Model Year(s)

Carline

Production Date Range

2017-2019

Impreza

July 28, 2016 – March 8, 2018

2018

Crosstrek

May 9, 2017 – April 2, 2018

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.

CAUTION: VEHICLE SERVICING PERFORMED BY UNTRAINED PERSONS COULD
RESULT IN SERIOUS INJURY TO THOSE PERSONS OR TO OTHERS.
Subaru Service Bulletins are intended for use by professional technicians ONLY. They
are written to inform those technicians of conditions that may occur in some vehicles,
or to provide information that could assist in the proper servicing of the vehicle. Properly
trained technicians have the equipment, tools, safety instructions, and know-how to
do the job correctly and safely. If a condition is described, DO NOT assume that this
Service Bulletin applies to your vehicle, or that your vehicle will have that condition.

Subaru of America, Inc. is
ISO 14001 Compliant
ISO 14001 is the international standard for
excellence in Environmental Management
Systems. Please recycle or dispose of

DESCRIPTION OF THE REMEDY:
Vehicles affected by this recall will require an inspection and potential replacement of the PCV valve
and hose.
OWNER NOTIFICATION:
Subaru will notify affected vehicle owners by first class mail within 60 days. Owners with a valid
email address on file will also be notified by email. Retailers will be advised when the notification is
scheduled.
RETAILER RESPONSIBILITY:
Please be advised that it is a violation of Federal law for a dealer to deliver a new motor vehicle
covered by a recall under a sale or lease until the defect is remedied. Therefore, any Authorized
Subaru Retailer failing to perform the applicable service procedures to correct all affected vehicles in their inventory prior to the vehicle being placed in service may be subject to civil penalties
of up to $21,000 per violation (i.e., for each vehicle), as provided in 49 CFR §578.6 and will also
be in breach of the Subaru Dealer Agreement.
Any vehicles listed in any recall/campaign that are in retailer stock must be:
•

Immediately identified.

•

Tagged or otherwise marked to prevent their delivery or use prior to repair.

•

Repaired in accordance with the repair procedures outlined in the Product Campaign Bulletin

Retailers are to promptly follow the applicable service procedures, to correct all affected vehicles in
their inventory (used, demo & SSLP). Additionally, whenever a vehicle subject to this recall is taken
into retailer inventory necessary steps should be taken to ensure the recall correction has been made
before selling or releasing the vehicle.
PART INFORMATION:
REMINDER: Always order the most up-to-date replacement parts based on the specific VIN being
repaired.
A new parts kit, p.n. X1181AA000 consisting of
a new steel PCV valve and hose will be available

SERVICE PROCEDURE / INFORMATION:
Due to a production error, the Positive Crankcase Ventilation (PCV) valve may fail causing its
internal components to fall into the crankcase. As a result, the engine may smoke excessively from
the exhaust. The repair involves removal of the PCV valve, inspection for failure and replacement.
If the valve has failed (come apart), further action is necessary to locate and remove the failed PCV
valve components.
REMINDER: Customer satisfaction and retention starts with performing quality repairs.
The service procedures for PCV valve and hose replacement remain unchanged. Always refer to
the applicable Service Manual and review the full requirements of the repair being performed. The
Service Manual procedures contain information critical to performing an effective repair the first
time and every time. This includes but is not limited to: important SAFETY precautions, proper
inspection criteria, necessary special tools, required processes and related one-time-use parts needed
for a complete and lasting repair.
IMPORTANT: The two flow charts below provide an overview for the service procedures. The
first is for Crosstrek and the second for Impreza. Detailed service procedures to be followed are also
provided and must reviewed completely before proceeding.
FLOW CHART FOR CROSSTREK:

FLOW CHART FOR IMPREZA:

STEP 1: Locate the PCV valve and check the identification color. If for some reason the color
cannot be identified, remove the PCV valve and confirm the condition (failed / come apart). If the
(unidentifiable) PCV valve is not broken, replace it with a new (BLUE) valve and PCV hose. If the
valve is broken, proceed as if it were a PINK valve using the flow chart(s) above as a guide.
•

If the valve has a PINK identification ring, proceed to STEP 2.

•

If the valve has a BLUE identification ring, STOP. The procedure is complete. Proceed to
the Claim Reimbursement and Entry Procedures section of this bulletin.

Step 2: Remove the PINK PCV valve and inspect it for breakage. Use the photos below for
reference.

•

If the PCV valve is BROKEN (NG), proceed to Step 3 and remove the engine following the
procedure in the applicable Service Manual.

•

If the PCV valve is OK (NOT broken), replace it with the new BLUE valve and hose from
the kit to complete the procedure following the applicable Service Manual.

Step 3: (If necessary), following the applicable Service Manual procedures, remove the engine
to collect the PCV valve component parts that may have fallen into the engine. Remove the oil
separator cover and collect the PCV valve components (4 small parts) as shown in the photos below.
If all the PCV valve components cannot be collected after removing the oil separator cover, proceed
with removing the engine oil pan to collect any remaining components.
Separator
Cover Removed

TIP: If any PCV valve components remain in the oil pan-side passage, CAREFULLY apply
compressed air to the oil pan-side passage as shown below.
IMPORTANT REMINDERS:
• Always wear safety glasses.
•

Never reuse the oil separator cover as it is a one-time use item. Replace it with
p.n. 11831AA260.

block assembly along with a new PCV valve and hose (kit) following the applicable Service
Manual procedures.

cover, PCV valve and hose (kit) then reassemble the vehicle following the applicable Service
Manual procedures to complete the procedure.
