INTRODUCTION

Subaru of America, Inc. (Subaru) is initiating a Recall Campaign for certain 2015-16 model year Forester 2.0XT and WRX vehicles.  Subaru has determined that vehicles affected by this Recall Campaign require inspection and possible replacement of the turbocharger air intake duct.

 

DESCRIPTION OF THE SAFETY DEFECT & SAFETY HAZARD

The turbocharger air intake duct on affected vehicles may have been produced with incorrect material that is susceptible to cracking. Should the turbocharger air intake duct crack, the engine may develop an abnormally rough idle, lower power and possibly stall. Should the engine suddenly lose power or stall while driving, there is an increased risk of a crash.

In addition, this condition may cause the “Check Engine” light located on the instrument panel to illuminate, indicating a malfunction has occurred. It could also have an adverse effect on vehicle exhaust emissions.

 

DESCRIPTION OF THE REMEDY

The repair procedure will involve inspecting and possibly replacing the turbocharger air intake duct. Inspection of the turbocharger air intake duct lot number (date) molded on the duct will be necessary to determine if replacement is required.

 

AFFECTED VEHICLES

  • Certain 2015-2016 model year Forester 2.0XT vehicles
  • Certain 2015-2016 model year WRX vehicles

Not all vehicles listed below are covered by this campaign. Coverage for all affected vehicles must be confirmed by using the Vehicle Coverage Inquiry function on subarunet.com.

RETAILER AFFECTED VIN LISTS

Each Subaru retailer will receive an affected VIN list from their Zone office when owner notification begins. Vehicles will be assigned to retailers in the affected VIN list as follows:

IMPORTANT: Retailer affected VIN lists include owner name and address information for vehicles affected by this recall. This information will enable retailers to follow-up with owners of potentially affected vehicles. The lists contain owners’ names and addresses obtained from State Motor Vehicle Registration Records. The use of such motor vehicle registration data for any other purpose is unlawful. Accordingly, retailers are urged to limit the use of these lists for the purpose of completion of this safety recall.

 

SUBARU RETAILER PROGRAM RESPONSIBILITY

Retailers are to promptly perform the applicable service procedures to correct all affected vehicles in their inventory. Additionally, whenever a vehicle subject to this recall campaign is taken into inventory or in for service, necessary steps should be taken to ensure the service program has been performed before selling or releasing the vehicle.

OWNER NOTIFICATION LETTER

IMPORTANT SAFETY RECALL

This notice applies to the VIN identified in the address section printed below.

 

Subaru Recall Campaign WTA-62
NHTSA Recall No. 16V-162
April 2016

 

Dear Subaru Owner:

This notice is sent to you in accordance with the National Traffic and Motor Vehicle Safety Act.

Subaru of America, Inc. has decided that a defect which relates to motor vehicle safety exists in certain 2015-2016 model year Subaru Forester 2.0XT and WRX vehicles.

You received this notice because our records indicate that you currently own one of these vehicles.

 

DESCRIPTION OF THE SAFETY DEFECT & SAFETY HAZARD

The engine turbocharger air intake duct may have been produced with an incorrect material that is susceptible to cracking. Should the engine turbocharger air intake duct crack, the engine may develop an abnormally rough idle, reduced power and possibly stall. Should the engine suddenly lose power or stall while driving, there is an increased risk of a crash.

In addition, this condition may cause the “Check Engine” light located on the instrument panel to illuminate, indicating a malfunction has occurred. It could also have an adverse effect on vehicle exhaust emissions.

 

DESCRIPTION OF THE REMEDY

Subaru will inspect the lot number molded on the engine turbocharger air intake duct to determine if it was produced with incorrect material. If a specific lot number is found, the duct will be replaced. If a different lot number is found, the duct was produced using the correct material and replacement is not necessary. The inspection and, if necessary, the repair will be performed at no cost to you.

 

WHAT YOU SHOULD DO

You should immediately contact your Subaru retailer (dealer) for an appointment to have your vehicle inspected and repaired, if necessary.

There are several important precautions you should take until this recall has been performed:

  • If you notice an abnormally rough engine idle or the “Check Engine” light located on the instrument panel illuminates while the engine is running, do not drive the vehicle. Contact your Subaru retailer for assistance.
  • If there is a loss of power or the engine stalls while driving, carefully steer the vehicle to a safe place on the side of the road. Do not continue to operate the vehicle. Immediately contact your Subaru retailer for assistance.

 

HOW LONG WILL THE REPAIR TAKE?

The time to perform the actual inspection is approximately 10 minutes. If replacement of the engine air duct is required, the repair will take an additional 20 minutes. However, it may be necessary to leave your vehicle for a longer period of time on the day of your scheduled appointment to allow your Subaru retailer flexibility in scheduling.

CALIFORNIA REGISTERED OWNERS

The California Air Resources Board requires that emission related campaigns be completed prior to California’s vehicle registration renewal process; without this repair, you will not be able to register your vehicle during your next annual registration. Upon completion of this campaign, your California dealer will complete and provide you a “Proof of Correction Certificate.” If required, present the certificate to the California Department of Motor Vehicles (the “DMV”) when renewing your California registration as proof of campaign completion. If the DMV does not request the certificate, we recommend that you keep it for your records.

In addition, the State of California requires that every vehicle must pass an emission test (SMOG Check) every two years and before it is sold. Without the service we are providing at no charge, your vehicle may not pass this test.

Your continued satisfaction with your Subaru is important to us.  Please understand that we have taken this action in the interest of your safety and your vehicle’s proper operation.  We sincerely apologize for any inconvenience this matter may cause and urge you to schedule an appointment as soon as possible to have this repair performed.

Sincerely,

Subaru of America, Inc.
