This bulletin is being revised to update the Warranty Transaction Information section to include
diagnostic labor time in the replacement labor codes for vehicles no longer covered under applicable
new vehicle limited warranties. Please discard all copies of bulletin 14652.
CONDITION
On some 2010-2012 model year Chevrolet Express and GMC Savana vehicles and 2011-2012
model year Chevrolet Silverado HD and GMC Sierra HD vehicles that are equipped with a 6.6L
diesel engine (LML/LGH), a malfunction-indicator light (MIL) may illuminate due to an offset in the
temperature sensor in the diesel-emission-reduction fluid (DEF) tank reservoir, increased tankheater resistance, or reductant-system performance.
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 DEF tank reservoir and/or supply module pump. 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 7, 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 7, 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.

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

A completed Customer Reimbursement Request Form. This form is mailed to the customer
or can be obtained through GM GlobalConnect.

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

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

CUSTOMER NOTIFICATION
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).

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/retailer for information on
whether your vehicle may benefit from the information.

Dear General Motors Customer:
As the owner of a 2010-2012 model year Chevrolet Express, 2010-2012 model year GMC
Savana, 2011-2012 model year Chevrolet Silverado HD, or 2011-2012 model year GMC Sierra
HD vehicle, your satisfaction with our product is very important to us.
This letter is intended to make you aware that, on some 2010-2012 model year Chevrolet Express
and GMC Savana vehicles and 2011-2012 model year Chevrolet Silverado HD and GMC Sierra
HD vehicles equipped with a 6.6L diesel engine, a malfunction-indicator light (MIL) may illuminate
due to an offset in the temperature sensor in the diesel-emission-reduction fluid (DEF) tank
reservoir, increased tank-heater resistance, or reductant-system performance.
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 2010-2012 model year Chevrolet
Express or GMC Savana or 2011-2012 model year Chevrolet Silverado or GMC Sierra 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 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, 2016 unless state law specifies a longer reimbursement period.
