INTRODUCTION

As part of our dedication to customer satisfaction, Subaru of America, Inc. is initiating a program to extend the original New Car Powertrain Limited Warranty coverage for excessive engine oil consumption on applicable vehicles to 8 years/100, 000 miles from the original warranty start date. This Warranty Extension will not cover any excessive engine oil consumption found to be a result of any condition(s) other than those specifically described in this bulletin.

This condition must be verified during an inspection and when determined necessary, an oil consumption test performed by an authorized Subaru retailer. SOA will inform vehicle owners this condition may exist via a customer letter. For vehicles within the coverage guidelines listed in this bulletin, customers can schedule an inspection appointment with an authorized Subaru retailer.

IMPORTANT: ALWAYS perform a Vehicle Coverage Inquiry on Subarunet to determine eligibility for this Warranty Extension before proceeding. The VIN should also be checked for any open campaigns or recalls at this time. See sample inquiry result below.
G13670977

Effective immediately through April 21, 2017, ALL affected vehicles, regardless of mileage and warranty start date will be covered for these repairs. All inspections and repairs must be completed prior to the April 21, 2017 expiration date of this Warranty Extension.

IMPORTANT: In the event a vehicle has exceeded 100, 000 miles prior to April 21, 2017, please contact the Subaru Claims Team at: 1-866-782-2782 to register the mileage PRIOR to claim submission.

After April 21, 2017, this coverage extends the vehicle's Powertrain Limited Warranty as it applies to excessive engine oil consumption to 8 years/100, 000 miles from the original warranty start date providing additional coverage for some vehicles. All inspections and repairs must be completed prior to expiration of this 8-year/100, 000 Warranty Extension.

This bulletin contains several important revisions regarding warranty coverage and for determining when an engine oil consumption test should be performed. Review the entire bulletin  to ensure full understanding of these and other changes.

Immediately  delete and discard any electronic or paper copies you may have saved locally as they are no longer valid. If you have any locally saved copies of Service Bulletins 02-143-13R, 02-144-13R and 02-145-13R, delete or discard them as they have been invalid since the original release date of this bulletin and should never be used. Vehicles confirmed  as having an excessive oil consumption condition which are within the supplied VIN ranges, will continue to be repaired by replacing the engine short block assembly.

VERY IMPORTANT:  Read and understand this bulletin COMPLETELY  before starting an oil consumption test or initiating any repairs.

It is critical to confirm  the actual condition prior to attempting repairs. Some oil consumption should be expected as a by-product of engine operation.  Failure to recognize this along with incorrectly diagnosing the condition can result in unnecessary repairs.

Examples of acceptable  engine oil consumption:

The information supplied in this bulletin is only applicable to vehicles within the provided specific production ranges and confirmed as having an oil consumption rate of MORE THAN  one-third (1/3) of a quart (10.6 fluid ounces) in 1200 miles as determined by an engine oil consumption test.

Concerns related to a possible oil consumption condition are generally initiated when the customer believes the engine oil level on the dipstick has dropped since the last time it was checked or when the low oil lamp illuminates. It is important to understand all the factors involved when determining if a repair is required or an oil consumption test should even be started.

REMINDER: Some oil consumption should be expected as a by-product of engine operation. 

How much and when it is consumed varies according to manufacturing tolerances, wear, and vehicle usage patterns. With the extended service intervals commonly used for today's engines combined with one or more of the conditions listed below, it may be necessary to add engine oil between the scheduled maintenance intervals:

Under these or similar operating conditions, the oil level should be checked more frequently. The engine oil and filter may also need to be changed more often.

As related information, the low oil level warning light (if equipped) is designed to illuminate when the engine oil level is approximately 1.1 quarts below full (engine OFF). Keep in mind, oil remains suspended in the engine while running and will not fully drain back until the engine has been shut off for at least 5 minutes. For this reason, the oil level should not be checked for at least 5 minutes after shutting the engine off. See Section 3 of the Owner's Manual for more information on the oil level warning system.

NOTE: **A procedure to reduce false illumination of low oil level warning lamp (if equipped) is provided later in this bulletin for how to address customer concerns of the low engine oil level warning lamp illuminating prematurely when the oil level is either full or nearly full.

SERVICE PROCEDURE/INFORMATION

Before starting any repairs, the first step is to always confirm the customer's complaint  . It is critical to get as much information from the customer as possible to help you make the most accurate diagnosis.

NOTE:
  • An oil consumption test will need to be completed to determine the proper course of action. There is a specific procedure and Oil Consumption Test form which must be completed. See Subarunet \ Service \ Forms  for the latest test form. Always print the latest form anytime a new test is started.
  • Where applicable, available reprogramming to reduce the possibility of false low engine oil level warning lamp illumination must be installed.
  • See Service Procedure to reduce false illumination of low oil level warning lamp (on models so equipped)  later in this bulletin for further instructions. This must be completed at either the start or end of the consumption testing regardless of the final outcome.
  • IMPORTANT: At the start of the Oil Consumption Test Form, specific information regarding what prompted (reason for) the testing must be collected. Once this questionnaire section of the form is completed, it must be faxed to 856-488-3199. Upon completion of the actual consumption test, the remainder of the form must be completed and faxed AGAIN to 856-488-3199. This information is being collected for quality assurance purposes only. You will not receive any response from these submissions. This is NOT  an authorization process. Proceed with any necessary testing or repairs as indicated by the information provided in this service bulletin, the Oil Consumption Test form results, Subaru's Claims Policies and Procedures, and your evaluation of the actual condition presented based upon your review of all three areas. Keep in mind, these repairs should only be completed when unusual oil consumption has been confirmed.

Before initiating the consumption test, all basic checks must be completed. These include but are not limited to): confirming the actual oil level, noting if any oil has been added prior to this visit and how much, checking for any external leaks, confirming PCV operation, and verifying that a consumption test has not already been started or completed previously. Always use the latest Oil Consumption Test form form found on Subarunet in the Service Forms area. Follow the instructions outlined on the form.

NOTE: The oil and filter change is only necessary if no prior consumption test has been completed or is already in process. There is no need for duplicate or repeat testing. One-time documented results are all that is required to move forward with these repairs. Always close the repair order on the day the oil change has been completed and submit the claim for the oil consumption test using the coding provided at the end of this bulletin. Indicate "Oil Consumption Test" in the comments field/box when entering your claim. DO NOT hold the repair order open until the vehicle returns.  Have the customer drive the vehicle then return for inspection when any of the following have occurred:
  • At least 1200 miles have elapsed
  • When the low engine oil level warning lamp illuminates (when equipped)
  • When the oil level reaches the lower hole in the dipstick/gauge (as determined by the customer).

The customer should be advised to not add oil unless there will be a significant delay before they can return for inspection once a low oil condition occurs. A one-time check of the oil consumption by the retailer is all that is needed to establish if the condition outlined in this bulletin applies.

SPECIFIC SERVICE PROCEDURES

The following information is provided to underscore service procedures specific to the repairs outlined in this bulletin. The procedures provided here are specific to certain steps in the overall process. They are not meant to represent the entire repair process from start to finish. In some cases, they will differ greatly from the Service Manual instructions and should be followed in place of the Service Manual for these specific areas only. For the balance of the repair procedure, refer to the Service Manual. It is highly recommended to review all of the Service Manual procedures for short block replacement then review these specific procedures to become familiar with the differences. 

REASSEMBLY

Begin by putting the new short block onto your engine stand using the same mounting points as before.

Important Reminders: 

SERVICE PROCEDURE TO REDUCE FALSE ILLUMINATION OF THE LOW OIL LEVEL WARNING LAMP (ON MODELS SO EQUIPPED)

Any repairs performed as part of this bulletin MUST include installation of the applicable ECM reprogramming file for Oil Level Detection and replacement of the oil level switch. Refer to the applicable TSBs as listed below:

VERY IMPORTANT:  If a vehicle is presented where no repairs for actual oil consumption are required but an oil consumption test was completed, BOTH  the applicable ECM reprogramming file for Oil Level Detection AND  the updated oil level switch MUST be installed before releasing the vehicle to the customer.

NOTE: SOA now highly recommends connecting the Midtronics GR8 Diagnostic Battery Charger to the vehicle and utilizing the Power Supply Mode feature anytime a vehicle control module is being reprogrammed. Once the GR8 is connected to the vehicle, as long as the battery is fully charged, it takes less than 3 minutes to boot-up the charger, select the Power Supply Mode, and have the battery voltage stabilized and ready for reprogramming.

VERY IMPORTANT:  This information is applicable to the Midtronics GR8 Diagnostic Battery Charger ONLY  . It does not apply to any other brand/type of "generic" battery charger whatsoever. ONLY  the GR8 and its Power Supply Mode feature has been tested and approved by Subaru of America, Inc. (SOA).

If the GR8 indicates the vehicle's battery must be charged, charge the battery using the GR8 before proceeding to reprogram the vehicle while using the Power Supply Mode.
