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.

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

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. 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.

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 (0.946 L) 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 13-06-01-003. 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.

Piston and Ring Replacement Procedure

Note: Review the following service procedures and technical bulletin in SI:

• Engine Replacement
• Technical Service Bulletin 13-06-01-003 placing a special emphasis on the PCV orifice between the #2 and #3 intake runners.
• Piston and Connecting Rod Disassemble
• Pistong and Connecting Rod Assemble
• Piston, Connecting Rod, and Bearing Installation (LAF, LAT, LE5, LE9, LEA, or LUK)

1. Remove the engine from the vehicle.
2. Remove the pistons from the engine.
3. Remove the pistons from the connecting rods.
4. Discard the pistons and piston rings.
5. Install the new piston rings onto the new pistons.
6. Install the new pistons onto the connecting rods.
7. Assemble the engine.
8. Install the engine into the vehicle.

Customer Reimbursement – For US

Customer requests for reimbursement of previously paid repairs to correct the condition described 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 GM representative prior to processing the request.

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

• A completed Customer Reimbursement Request Form. This form is mailed to the customer or can be obtained through GM GlobalConnect.
• The name and address of the person who paid for the repair.
• 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 Warranty Administration Bulletin 11-00-89-004.

— Original paid receipt confirming the amount of unreimbursed repair expense(s) (including Service Contract deductibles), a description of the repair, and the person or entity performing the repair.

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 GM representative prior to processing the request.

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.

For Use With Vehicles Still Covered Under Applicable New Vehicle Limited Warranties

Note: For reimbursements on vehicles covered under warranty, refer to the Policies and Procedures Manual.

For Use With Vehicles No Longer Covered Under Applicable New Vehicle Limited Warranties

* The amount identified in Net/Reimbursement should represent the dollar amount reimbursed to the customer.
