Coverage
Adjustment

Some 2013 model year Chevrolet Equinox and GMC Terrain vehicles equipped with a 2.4L engine
(RPO LEA) may exhibit excessive engine oil consumption (less than 2,000 miles [3,200 km] per quart
[0.946 L] of engine oil), due to piston ring wear. If this condition is present, an audible rattle or knock
from the engine may be heard. The engine oil pressure telltale may illuminate on the instrument panel
or the following message may appear in the Driver Information Center: "Oil Pressure Low – Stop
Engine".
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.
For vehicles covered by Vehicle Service Contracts, all eligible claims with repair orders on or after
January 17, 2020, 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 January 17, 2020, must be submitted
to the Service Contract provider.

Correction

Vehicle owners or lessees who paid for repairs referenced in this Special Coverage (“Customers”) are
eligible for reimbursement of their reasonable and customary expenses in accordance with the
procedures specified below. The conditional right to reimbursement is provided by GM solely in the
interest of customer satisfaction and is personal to Customers. Customers may not assign and GM
does not consent to any assignment of any Customer’s right to submit reimbursement claims, or to
receive reimbursement, or any other rights granted by this Special Coverage to any third party,
including but not limited to service contract providers, and this Special Coverage is not intended to
and does not confer any third party beneficiary, subrogation or contribution rights, or any other rights
to reimbursement, against GM, whether in law, equity or otherwise, on any third parties.
Dealers are to perform an oil consumption test and install new pistons and piston rings if excessive
consumption is found. In addition, dealers are to repair or replace any engine components that require
repair or replacement if the need for such repair or replacement was solely caused by excessive oil
consumption due to piston ring wear. The repairs will be made at no charge to the Customer.

Service Procedure
Customers will be notified of the Special Policy by General Motors (see copy of owner letter included with this bulletin).
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.
Determine the rate of oil consumption.
•

If the oil consumption test indicates that the rate of consumption is equal to or less than 1 quart (0.946L) of oil
every 2,000 miles (3,200 km), note the oil consumption rate and explain to the customer that their engine meets
the guidelines for oil consumption at this time. 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, 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 13-06-01-003. 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 13-06-01-003 for more information.

coverage but direct the customer to timely submit the claim form attached to their letter.

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.

N192291100 Excessive Engine Oil Consumption – US Only
January 17, 2020
This notice applies to your vehicle, VIN: _____________________________________
Dear General Motors Customer:
As the owner of a 2013 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 2013 model year Chevrolet Equinox or GMC Terrain vehicles,
equipped with a 2.4L engine, may exhibit excessive engine oil consumption (less than 2,000 miles [3,200 km] per
quart [0.946 L] of engine oil), due to piston ring wear. If this condition is present, an audible rattle or knock from the
engine may be heard. The engine oil pressure warning light may illuminate on the instrument panel or the following
message may appear in the Driver Information Center: “Oil Pressure Low – Stop Engine.”
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 2013 model year Chevrolet Equinox or GMC Terrain within 7 years and 6 months
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: It is a good idea to check the engine oil level at each fuel fill. Your vehicle owner manual has
instructions on checking engine oil in the Vehicle Care section. If you believe that your vehicle has the condition described
above, and it is within both the time and mileage limits set forth above, diagnosis, and repairs and adjustments if needed,
which qualify 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 previously paid for repairs solely caused by the condition described in this letter (including
piston assembly repair or replacement and/or repair or replacement of other engine components that was required
and caused solely as the result of excessive oil consumption due to piston ring wear) within the time and mileage limits
of the Special Coverage, or if you incurred reasonable rental vehicle costs while such repairs were being performed, you
may complete the enclosed reimbursement claim form along with supporting documents showing that the repairs were
required and performed solely as the result of excessive oil consumption due to piston ring wear. The completed claim
form and required documentation of eligible expenses must be postmarked no later than May 16, 2020 to the following
address:
2.4 Liter Oil Consumption Litigation
c/o Analytics Consulting LLC
P.O. Box 2003
Chanhassen, MN 55317-2003
Repairs that were performed after the expiration of the time or mileage limits of this Special Coverage are not
eligible for reimbursement.
The right to submit reimbursement claims is provided by GM solely in the interest of customer satisfaction and is
personal to vehicle owners and lessees who previously paid for repairs within the time and mileage limits of this Special
Coverage (“Customers”). Customers may not assign and GM does not consent to any assignment of any Customer’s
right to submit reimbursements claims, or to receive reimbursement, or any other rights granted by this Special
Coverage to any third party, including but not limited to service contract providers, and this Special Coverage
is not intended to and does not confer any third party beneficiary, subrogation or contribution rights, or any other
rights to reimbursement, against GM, whether in law, equity or otherwise, in favor of any third parties.
If you have any questions or need any assistance with obtaining repairs covered under this Special Coverage,
please contact your dealer or the appropriate Customer Assistance Center at the number listed below.
