SPECIAL COVERAGE
SUBJECT:
Special Coverage Adjustment - Loss of Power Steering Assist
MODELS:
2008-2011 Buick Enclave
2009-2011 Chevrolet Traverse
2007-2011 GMC Acadia
2007-2010 Saturn OUTLOOK
The bulletin has been revised to update the Part Information and torque specs within the Service
Procedure. Please discard all copies of bulletin 14329A.
Dealers are to refer to the General Motors Service Policies and Procedures Manual, Section 1.4.1.B
- Vehicles Outside of a Special Coverage Adjustment, for guidelines on handling vehicles that are
not involved in this special coverage but may be displaying the same condition.
CONDITION
Some 2008-2011 model year (MY) Buick Enclave, 2009-2011 MY Chevrolet Traverse, 2007-2011
MY GMC Acadia, and 2007-2010 MY Saturn OUTLOOK vehicles may develop a power steering
pump wear condition that can cause an intermittent drop of power steering hydraulic pressure that
will cause reduced or loss of steering assist. The vehicle may revert to manual steering which
requires greater driver effort, particularly at low vehicle speeds.
SPECIAL COVERAGE ADJUSTMENT
This special coverage covers the condition described above for a period of 10 years or 150,000
miles (240,000 km), whichever occurs first, from the date the vehicle was originally placed in service,
regardless of ownership.
Dealers are to flush the power steering system, replace the power steering pump, and if it hasn't
already been replaced, install a new steering gear valve housing. The repairs will be made at no
charge to the customer.
For vehicles covered by Vehicle Service Contracts, all eligible claims with repair orders on or after
September 5, 2014, are covered by this special coverage and must be submitted using the labor
operation codes provided with this bulletin. Claims with repair orders prior to September 5, 2014,
must be submitted to the Service Contract provider.
VEHICLES INVOLVED
All involved vehicles are identified by Vehicle Identification Number on the Applicable Warranties
section in GM Global Warranty Management system. Dealership service personnel should always
check this site to confirm vehicle involvement prior to beginning any required inspections and/or
repairs. It is important to routinely use this tool to verify eligibility because not all similar vehicles
may be involved regardless of description or option content.

SERVICE PROCEDURE
Note: Check the power steering fluid level before evaluating or diagnosing the system and adjust
as necessary. Low fluids may demonstrate a similar concern and any leaks in the system causing
low fluid level should be brought to the attention of the customer, but it is not covered under this
special coverage. Steering gear boot staining does not necessarily indicate a sign of leakage and
should be evaluated as per TSB 12-02-32-004A.
1.
Verify the conditions under which the customer may be experiencing the intermittent loss of
assist, confirming that it is occurring at slow speed maneuvers or at low engine RPM driving. If
the condition is present at the time of diagnosis, it should be present between 1800 and 2000
rpm. Raise engine speed to this RPM band with the vehicle in gear and turn the steering
wheel to duplicate the concern. If the loss of assist is present at idle or in conditions at higher
vehicle speed, refer to the appropriate diagnostic information in SI for further diagnosis of the
system.
 If the power steering pump does NOT require replacement, no further action is required.
Inform the customer that any additional diagnosis and repairs are not covered under this
special coverage.
 If the condition can be duplicated or if the conditions under which the customer is
experiencing the intermittent loss of assist agrees with the conditions mentioned above, the
power steering pump requires replacement, proceed to the next step.
Note: Check the vehicle history before beginning repairs. Ensure that the vehicle has been
updated to DEXRON®-VI fluid. This is fluid replacement usually takes place when performing PI
0620 and/or PI0029. Examining the fluid is also recommended to determine if the system has
been convert to DEXRON®-VI. The DEXRON®-VI fluid is red in color, the original fluid is light
brown in color. If after examining the fluid color and condition, it cannot be determined if the fluid
has been updated or if it is possible to confirm the fluid has not been updated, see the Installing
New Steering Gear Housing Kit and Fluid section below.
2.
Replace the power steering pump and fluid. Refer to Power Steering Pump Replacement in
SI.
Caution: Due to the interface between the pinion shaft seal and the fluid, it is critical to ensure
that no old fluid comes in contact with the new seal (the new seal is included with the Steering
Gear Housing Kit). Be sure to thoroughly flush all old fluid from the system prior to installing the
new housing.

Installing New Steering Gear Housing Kit and Fluid
If the fluid has not been updated to DEXRON®-VI fluid, the following steps must be performed in
addition the pump replacement procedure. The new steering gear housing kit will include either a
tag or an owner’s manual insert that identifies the vehicle has been converted to DEXRON®-VI. If
the kit includes the tag, it should be installed on the power steering reservoir filler neck and
secured with the cap. If the kit includes the insert, it should be placed in the vehicle owner’s
manual in the appropriate section. Also, please advise the customer that their vehicle has been
converted to DEXRON®-VI.
1.

CUSTOMER NOTIFICATION
General Motors will notify customers of this special coverage on their vehicles (see copy of typical
customer letter included with this bulletin - actual divisional letter may vary slightly).
GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of
conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained
technicians have the tools, equipment, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO
NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your dealer/retailer for information on
whether your vehicle may benefit from the information.
