Condition

Special
Coverage
Adjustment

In certain 2014 model year Chevrolet Impala and Malibu vehicles equipped with a 2.5L engine, the
rocker arm oil control valve, (OCV), may malfunction. If this occurs, the valve may fail to correctly control
oil gallery pressure into the engine’s rocker arm system or leak small amounts of oil onto the exterior of
the engine. The customer may notice the engine running rough. In addition, the Malfunction Indicator
Lamp (Check Engine Light) may illuminate and a diagnostic trouble code related to the OCV may set.
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.
For vehicles covered by Vehicle Service Contracts, all eligible claims with repair orders on or after June
18, 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 June 18, 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 replace the rocker arm oil control valve. The repairs will be made at no charge to the
customer.

control valve to order.
Reminder: Parts may be removed from Retail Inventory Management (RIM). Dealers should review the affected parts

This notice applies to your vehicle, VIN: _____________________________________
Dear General Motors Customer:
As the owner of a 2014 model year Chevrolet Impala or Malibu, your satisfaction with our product is very important to
us.
This letter is intended to make you aware that in certain 2014 model year Chevrolet Impala and Malibu vehicles
equipped with a 2.5L engine, the rocker arm oil control valve, (OCV), may malfunction. If this occurs, the valve may fail
to correctly control oil gallery pressure into the engine’s rocker arm system or leak small amounts of oil onto the exterior
of the engine. The customer may notice the engine running rough. In addition, the Malfunction Indicator Lamp (Check
Engine Light) may illuminate and a diagnostic trouble code related to the OCV may set.
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 2014 model year Impala or Malibu 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 already 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 July 31, 2020,
unless state law specifies a longer reimbursement period.
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 referenced in this Special Coverage
(“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.
