site should always be checked to confirm vehicle involvement prior to beginning any required inspections and/or repairs.
Condition

Special
Coverage
Adjustment

Certain 2016 Chevrolet Express, Chevrolet Silverado HD, GMC Savana and GMC Sierra HD vehicles
that are equipped with a diesel engine (LML/LGH) may have a condition which causes an offset in the
temperature sensor in the diesel-emission-reduction fluid (DEF) tank reservoir or causes the DEF heater
performance to degrade. If this condition occurs, the Malfunction Indicator Light (Check Engine Light)
will illuminate, the “Service Exhaust Fluid System” or “Service Emission System” message will be
displayed, and a diagnostic trouble code related to the condition will be 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
November 25, 2019, 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 November 25, 2019, 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 DEF tank reservoir as necessary. The repairs will be made at no charge to
the customer.

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.

Dear General Motors Customer:
As the owner of a 2016 model year Chevrolet Express, Chevrolet Silverado HD, GMC Savana or GMC Sierra HD, your
satisfaction with our product is very important to us.
This letter is intended to make you aware that some 2016 model year Chevrolet Express, Chevrolet Silverado HD, GMC
Savana or GMC Sierra HD vehicles, equipped with a diesel engine, may have a condition which causes an offset in the

to degrade. If this condition occurs, the Malfunction Indicator Light (Check Engine Light) will illuminate, the “Service
Exhaust Fluid System” or “Service Emission System” message will be displayed, and a diagnostic trouble code related
to the condition will be 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 2016 model year Chevrolet Express, Chevrolet Silverado HD, GMC Savana or GMC
Sierra HD 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 December 31,
2020, unless state law specifies a longer reimbursement period.

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.
