Program Bulletin
CUSTOMER SATISFACTION PROGRAM
SUBJECT:

Remanufactured High Feature V6 Engine Piston Ring Gap

MODELS:

2009–2010 Buick Enclave
2010 Buick LaCrosse
2009–2010 Chevrolet Traverse
2009–2010 GMC Acadia
2009–2010 Saturn OUTLOOK

CONDITION
Certain 2009-2010 model year Buick Enclave, Chevrolet Traverse, GMC Acadia, Saturn
OUTLOOK and 2010 model year Buick LaCrosse model vehicles may have had remanufactured
engines installed during a service repair that were built with incorrect piston rings. This may result
in engine misfires, lack of power, rough running, oil consumption and eventually engine failure due
to oil consumption.
CORRECTION
Dealers are to inspect engine serial numbers. If the serial number matches a list of suspect
engines, the engine will be replaced.
VEHICLES INVOLVED
All involved vehicles are identified by Vehicle Identification Number on the Investigate Vehicle
History screen 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.
For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle
identification number, customer name, and address information has been prepared and will be
provided to US and Canadian dealers through the GM GlobalConnect Recall Reports, or sent
directly to export dealers. Dealers will not have a report available if they have no involved vehicles
currently assigned.
The listing may contain customer names and addresses obtained from Motor Vehicle Registration
Records. The use of such motor vehicle registration data for any purpose other than follow-up
necessary to complete this program is a violation of law in several states/provinces/countries.
Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete
this program.

and Aftersales (GMCCA). Please refer to your “involved vehicles listing” before ordering parts.
Order parts on a CSO = Customer Special Order only. DRO’s will be cancelled. All orders will
be reviewed prior to being filled.

availability, dealers are encouraged not to order parts for use as shelf stock.
Parts should only be ordered when inspection determines that it is necessary
to replace the engine.
Note: Use the vehicle identification number (VIN) and the GM Electronic Parts Catalog (EPC) to
determine which engine to order.

COURTESY TRANSPORTATION
The General Motors Courtesy Transportation program is intended to minimize customer
inconvenience when a vehicle requires a repair that is covered by the New Vehicle Limited
Warranties. The availability of courtesy transportation to customers whose vehicles are within the
warranty coverage period and involved in a product program is very important in maintaining
customer satisfaction. Dealers are to ensure that these customers understand that shuttle service
or some other form of courtesy transportation is available and will be provided at no charge.
Dealers should refer to the General Motors Service Policies and Procedures Manual for Courtesy
Transportation guidelines.
WARRANTY TRANSACTION INFORMATION
Submit a transaction using the table below. All transactions should be submitted as a ZFAT

DEALER PROGRAM RESPONSIBILITY
All new, used, GM Certified Used, courtesy transportation vehicles, dealer shuttle vehicles, etc. in
dealers' possession and subject to this recall must be held and inspected/repaired per the service
procedure of this bulletin before customers take possession of these vehicles. Involved vehicles
must be held and not delivered to customers, dealer-traded, released to auction, used for
demonstration, or any other purpose.
All GM Certified Used vehicles currently in the dealers’ inventory within the Certified Pre-Owned
Inventory System (CPOIS) will be de-certified and must be held and remedied per the service
procedure in this bulletin. Upon submitting an accepted/paid warranty transaction in the Global
Warranty Management (GWM) system, the vehicle can be re-certified for sale within the CPOIS
system, or once again be used in the CTP program.
Dealers are to service all vehicles subject to this program at no charge to customers, regardless
of mileage, age of vehicle, or ownership, from this time forward.
Customers who have recently purchased vehicles sold from your vehicle inventory, and for which
there is no customer information indicated on the involved vehicle listing, are to be contacted by
the dealer. Arrangements are to be made to make the required correction according to the
instructions contained in this bulletin. A copy of the customer letter is provided in this bulletin for
your use in contacting customers. Program follow-up cards should not be used for this purpose,
since the customer may not as yet have received the notification letter.
In summary, whenever a vehicle subject to this program enters your vehicle inventory, or is in your
facility for service in the future, you must take the steps necessary to be sure the program
correction has been made before selling or releasing the vehicle.

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 for information on whether your vehicle may benefit from the information.
