SERVICE CAMPAIGN BULLETIN

Reference Number(s): WVG-17, Date of Issue:  December 2008
SUBARU: 2008-2009MY Tribeca

INTRODUCTION

Subaru of America, Inc. has determined that certain 2008 & 2009 Tribeca models may have been produced with an improperly installed Vehicle Dynamic Control (VDC) G sensor. This sensor is designed to be mounted in a forward facing direction but may have been installed backwards during production.

There is a potential safety risk associated with this condition. The VDC G sensor is a component of the vehicles electronic stability / traction control system and is located in the passenger compartment beneath the center console. If the sensor was improperly installed, vehicle handling characteristics during hard braking, sudden turns or other quick maneuvers could cause the vehicle to react in an unexpected manner or result in unstable handling. Under extreme conditions, the driver could lose control of the vehicle and a crash could occur. The driver would have no prior warning that this condition exists.

The Owner Notification letter, found at the end of this bulletin, recommends the vehicle driver "turn off" the Traction Control System until the inspection and, if necessary, repair is performed. Disabling the system will eliminate the possibility of a malfunction associated with an incorrectly installed VDC G sensor. Please refer to the letter for additional information.

This recall will involve inspecting the position of the VDC G sensor. If the sensor is found to be installed correctly, no further action is needed. If the sensor is found to be installed incorrectly (backwards), the sensor must be removed and reinstalled in the correct position. The VDC system will also require reprogramming to ensure proper operation. Please refer to the Service Procedure section of this bulletin for more details.

AFFECTED VEHICLES

Potentially affected vehicles are identified in the VIN range chart below. Prior to performing repairs, confirm coverage for potentially affected vehicles by using the Vehicle Coverage Inquiry in the Dealer Communication System (DCS).

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 Dealer failing to perform the applicable service procedures defined in this bulletin to correct all affected vehicles in their inventory (new, used, demo) prior to the vehicle being placed in service may be subject to civil penalties of up to $5,000 per violation (i.e., for each vehicle), as provided in 49 USC 30165(a) of the Safety Act, and will also be in breach of the Subaru Dealer Agreement. 

SERVICE PROCEDURE

This recall will involve inspecting the position of the VDC G sensor. If the sensor is found to be installed correctly, no further action is needed. If the sensor is found to be installed incorrectly (backwards), the sensor must be removed and reinstalled in the correct position. The VDC system will also require reprogramming to ensure proper operation.

VDC G SENSOR POSITION INSPECTION

The VDC G sensor is located in the center of the console just below the transmission shifter.

NOTE: the center console was removed for illustration purposes.

    G05901673

    In either case, the display will go back to the function check sequence after a few seconds. Center the steering wheel and repeat the procedure.

    NOTE: Centering is best performed by moving the steering wheel to the left and right of the center point and then back to center.
  8. When the steering wheel is centered the following screen will be displayed indicating the alignment procedure is beginning.

Important Safety Recall Notice

Subaru Recall Campaign WVG-17

NHTSA Recall No. 08V-645

December 2008

Dear Subaru Owner: 

This notice is sent to you in accordance with the requirements of 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 2008 and 2009 model year Subaru Tribeca vehicles.

DESCRIPTION OF THE SAFETY DEFECT 

Subaru has determined that your vehicle could have been manufactured with an improperly installed Vehicle Dynamic Control (VDC) G sensor. This sensor is designed to be mounted in a forward facing direction but may have been installed backwards during production.

DESCRIPTION OF THE SAFETY HAZARD 

The VDC G sensor is a component of your vehicle's electronic stability / traction control system and is located in the passenger compartment beneath the center console. If the sensor was improperly installed, vehicle handling characteristics during hard braking, sudden turns or other quick maneuvers could cause the vehicle to react in an unexpected manner or result in unstable handling. Under extreme conditions, the driver could lose control of the vehicle and a crash could occur. The driver would have no prior warning that this condition exists.

REPAIRS 

To correct this condition, Subaru will inspect the position of the VDC G sensor. If the sensor is found to be installed correctly, no further action is needed. If the sensor is found to be installed incorrectly (backwards), the sensor will be removed and reinstalled in the correct position. The VDC system will also be reprogrammed to ensure proper operation.

WHAT YOU SHOULD DO PROMPTLY 

You should immediately contact your Subaru Dealer for an appointment to have the VDC G sensor inspected and any related repairs performed at no cost to you.

In the meantime, until the VDC G sensor has been inspected and, if necessary repositioned, we recommend that you "turn off" your vehicle's Traction Control System. Disabling the system will eliminate the possibility of a malfunction associated with an incorrectly installed VDC G sensor. However, please be aware that it will also completely disable your vehicle's electronic stability / traction control system. The system can be "turned off" by depressing the Traction Control System switch located at the left lower instrument panel. When the system is turned off, the Vehicle Dynamics Control monitor light will illuminate on the instrument cluster indicating the system is deactivated. It will be necessary to follow this procedure each time the vehicle's engine is started. Please see the following sections in chapter 7 of your Tribeca Owner's Manual for additional information: 1) "Vehicle Dynamics Control system monitor", and (2) "Traction Control system OFF switch".

If you choose not to turn off the VDC system, please remain alert for the conditions and safety hazards described in this letter and take appropriate precautions when operating your vehicle.

HOW LONG WILL THE REPAIR TAKE? 

The actual time to inspect the VDC G sensor is approximately 10 minutes. It will take an additional 20 minutes if the sensor requires repositioning and reprogramming. However, it may be necessary to leave your vehicle the full day of your scheduled appointment to allow your dealer flexibility in scheduling. Please present this letter to your Subaru Dealer at the time this repair procedure is performed.
