#14717: Special Coverage Adjustment – Clutch Activation System – (Sep 4, 2015)

Subject:	14717 – Special Coverage Adjustment – Clutch Activation System
Models:	2005-2013 Chevrolet Corvette
	Equipped with Manual Transmission (RPO MM6, MZ6, MH3 or ME2)

Condition

On some 2005-2013 model year Chevrolet Corvette vehicles equipped with a manual transmission (RPO MM6, MZ6, MH3 or ME2), the clutch system may fail if unapproved fluids are used to service the system or if a high-pressure pulse occurs during a clutch self-adjustment event. If the clutch system fails, the clutch pedal may not return if depressed. If the clutch pedal does not return, it may be possible to start the vehicle when the transmission is in any gear. This could result in unexpected vehicle movement when the engine is started.

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 clutch master cylinder with a revised unit that is more robust against pressure pulses, and that includes a new fluid reservoir with improved labeling for use of proper fluid. 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 September 3, 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 September 3, 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.

Parts Information

Parts required to complete this special coverage are to be obtained from General Motors Customer Care and Aftersales (GMCCA).

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 September 30, 2016, unless otherwise specified by state law. If this is not convenient for the customer, the customer may mail the completed Customer Reimbursement Request Form and all required documents to the GM Customer Assistance Center. Repairs must have occurred within the 10 years 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:

• 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.

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.

Vehicles Still Covered Under Applicable New Vehicle Limited Warranties

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

Vehicles No Longer Covered Under Applicable New Vehicle Limited Warranties

Note: To avoid having to “H” route the customer reimbursement transaction for approval, it must be submitted prior to the repair transaction.

* The amount identified in “Net Item” should represent the dollar amount reimbursed to the customer.

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).
