SPECIAL COVERAGE
SUBJECT: Special Coverage Adjustment – Excessive Engine Oil Consumption
MODELS: 2011 Chevrolet Equinox

Equipped with 2.4L Engine (LAF)

orifice procedure in the referenced Technical Service Bulletin. Please discard all copies of bulletin
15285C.
CONDITION
Some 2011 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 the following message may appear in the Driver Information Center: “Oil Pressure Low –
Stop Engine”.
SPECIAL COVERAGE ADJUSTMENT
This special coverage covers the condition described above for a period of 7 years and 6 months
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
July 21, 2015, 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 July 21, 2015, 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 number 12312.
Page 3 April 2017 Bulletin No.: 15285D
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.
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.

in this bulletin are to be submitted to the dealer by August 31, 2016, unless otherwise specified by
state law. If this is not convenient for the customer, they may mail the completed Customer
Reimbursement Request Form and all required documents to the GM Customer Assistance Center.
Repairs must have occurred within the 7 years and 6 months of the date the vehicle was originally
placed in service, or 120,000 miles, whichever occurs first.
All reasonable and customary costs to correct the condition described in this bulletin should
be considered for reimbursement. Any questions or concerns should be reviewed with your

When a customer requests reimbursement, they must provide the following:

 Paid receipt confirming the amount of the repair expense, a description of the repair, and
the person or entity performing the repair.
IMPORTANT: GM requires dealers to approve or deny a reimbursement request within 30 days of
receipt. If a reimbursement request is approved, the dealer should immediately issue a check to
the customer and submit an appropriate warranty transaction for the incurred expense. If a
reimbursement request is denied, the dealer MUST provide the customer with a clear and concise
explanation, in writing, as to why the request was denied. The bottom portion of the Customer
Reimbursement Request Form may be used for this purpose. If the denial was due to missing
documents, the customer can resubmit the request when the missing documents are obtained, as
long as it is still within the allowed reimbursement period.
Warranty transactions for customer reimbursement of previously paid repairs are to be submitted
as required by GM Global Warranty Management. Additional information can also be found in

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.
Note: The labor times have been revised in the labor time files. The Labor Time Guide was
updated February 1, 2016.

Dear General Motors Customer:
As the owner of a 2011 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 2011 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 the following message in the Driver Information Center: “Oil
Pressure Low – Stop Engine”. See your owner manual for additional information on what to do if
the vehicle displays this message.
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 2011 model year Chevrolet Equinox or

charge. Diagnosis or repair for conditions other than the condition described above is not

What You Should Do: Be sure to maintain proper engine oil level at all times and have the oil
changed when the CHANGE ENGINE OIL SOON message appears on the Driver Information
Center. 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

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.
