SPECIAL COVERAGE
SUBJECT:

Special Coverage Adjustment – Excessive Engine Oil Consumption

MODELS:

2010 Chevrolet Equinox
2010 GMC Terrain
Equipped with 2.4L Engine (LAF)

This bulletin has been revised to include warranty information for vehicles still covered under the
original powertrain warranty. Please discard all copies of bulletin 14159.
CONDITION
Some 2010 model year Chevrolet Equinox and GMC Terrain vehicles, equipped with a 2.4L
engine, may exhibit excessive engine oil consumption (less than 2,000 miles per quart of engine
oil), due to piston ring wear. If this condition is present, the oil can light may illuminate on the
instrument panel or one of the following messages may appear in the Driver Information Center:
“Engine Oil Low – Add Oil” or “Oil Pressure Low – Stop Engine”.
SPECIAL COVERAGE ADJUSTMENT
This special coverage covers the condition described above for a period of 10 years or 120,000
miles (193,000 km), whichever occurs first, from the date the vehicle was originally placed in service,
regardless of ownership.
Dealers are to replace the 4 piston assemblies. 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
August 15, 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 August 15, 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: This special policy covers repairs after the original powertrain warranty has expired. For
vehicles still covered under the original powertrain warranty, the labor code operations should be
used from bulletin 13-06-01-003.
Note: Technicians should perform an oil consumption test to determine if the pistons and rings
must be replaced. Follow the latest version of Corporate Bulletin Number 01-06-01-011 to perform
an oil consumption test. Before starting the oil consumption test, verify the ECM has latest
TIS2web calibrations to adjust the engine oil life monitor to a maximum of 7,500 miles (12,070 km)
— Refer to the latest version of Customer Satisfaction Bulletin number12312.
1. Determine the rate of oil consumption.


If the oil consumption test indicates that the rate of consumption is less than 1 quart (0.946L)
of oil every 2,000 miles (3,200 km), note the oil consumption rate and the date that the ECM
was reprogrammed. No further action is required.



If the oil consumption test indicates that the rate of consumption is greater than 1 quart
(0.946 L) of oil every 2,000 miles (3,200 km), note the oil consumption rate, the date that the
ECM was reprogrammed and replace the pistons and rings.

Bulletin No.: 14159A

Note: The repair is to replace the pistons and rings. In some cases the bore surface may not have
a uniform look to the finish (zebra stripes) as shown in Technical Service Bulletin 13-06-01-003F.
As a result, some technicians may question whether the engine should be repaired or replaced.
After careful evaluation, GM Powertrain has determined that the new pistons and rings will
perform correctly in bores that have this appearance so engine replacement should not be
necessary. The cylinder bores do not need any machine or honing work performed on them. Refer
to Technical Service Bulletin 13-06-01-003F for more information.

COURTESY TRANSPORTATION – For US and Canada
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 ZREG
transaction type, unless noted otherwise.
Note: This special policy covers repairs after the original powertrain warranty has expired. For
vehicles still covered under the original powertrain warranty, the labor code operations
should be used from bulletin 13-06-01-003 as shown below.
Note: To avoid having to "H" route the customer reimbursement transaction for approval, it must
be submitted prior to the repair transaction.

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.

August 2014

Dear General Motors Customer:
As the owner of a 2010 model year Chevrolet Equinox or GMC Terrain, your satisfaction with our
product is very important to us.
This letter is intended to make you aware that some 2010 model year Chevrolet Equinox and
GMC Terrain vehicles, equipped with a 2.4L engine, may exhibit excessive engine oil
consumption (less than 2,000 miles per quart of engine oil), due to piston ring wear. Check your
oil level periodically. Also, if this condition is present, the oil can light may illuminate on your
instrument panel or you may have one of the following messages in the Driver Information Center:
“Engine Oil Low – Add Oil” or “Oil Pressure Low – Stop Engine”. See your owner manual for
additional information on what to do if the vehicle displays one of these messages.
Do not take your vehicle to your GM dealer as a result of this letter unless you believe that
your vehicle has the condition as described above.
What We Have Done: General Motors is providing owners with additional protection for the
condition described above. If this condition occurs on your 2010 model year Chevrolet Equinox or
GMC Terrain within 10 years of the date your vehicle was originally placed in service or 120,000
miles (193,000 km), whichever occurs first, the condition will be repaired for you at no charge.
Diagnosis or repair for conditions other than the condition described above is not covered under
this special coverage program.
What You Should Do: If you believe that your vehicle has the condition described above, repairs
and adjustments qualifying under this special coverage must be performed by a General Motors
dealer. You may want to contact your GM dealer to find out how long they will need to have your
vehicle so that you may schedule the appointment at a time that is convenient for you. This will
also allow your dealer to order parts if they are not already in stock. Keep this letter with your other
important glove box literature for future reference.
Reimbursement: If you have paid for repairs for the condition described in this letter, please
complete the enclosed reimbursement form and present it to your dealer with all required
documents. Working with your dealer will expedite your request, however, if this is not
convenient, you may mail the completed reimbursement form and all required documents to
Reimbursement Department, PO Box 33170, Detroit, MI 48232-5170. The completed form and
required documents must be presented to your dealer or received by the Reimbursement
Department by September 30, 2015, unless state law specifies a longer reimbursement period.
