Condition

Special
Coverage

Certain 2021 model year Chevrolet Colorado and GMC Canyon vehicles, equipped with a 2.8L diesel
engine (RPO LWN), could have a condition that may intermittently cause the throttle body motor to fail
to complete the throttle position learn cycle within the allowed time. If this condition were to occur, the
Malfunction Indicator Lamp (Check Engine Light) would illuminate, and a diagnostic trouble code would
set. The engine may also be placed in a reduced power mode.
This special coverage covers the condition described above for a period of 15 years or 150,000 miles
(240,000 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 August
13, 2024, 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 August 13, 2024, must be submitted to the
Service Contract provider.

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 throttle body as necessary. The repairs will be made at no charge to the
customer.

This notice applies to your vehicle, VIN: _____________________________________
Dear General Motors Customer:
As the owner of a 2021 model year Chevrolet Colorado or GMC Canyon, your satisfaction with our product is very
important to us.
This letter is intended to make you aware that some 2021 model year Chevrolet Colorado or GMC Canyon vehicles,
equipped with a 2.8L diesel engine, could have a condition that may intermittently cause the throttle body motor to fail to
complete the throttle position learn cycle within the allowed time. If this condition were to occur, the Malfunction
Indicator Lamp (Check Engine Light) would illuminate, and a diagnostic trouble code would set. The engine may also
be placed in a reduced power mode.
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 2021 Chevrolet Colorado or GMC Canyon within 15 years of the date your vehicle was
originally placed in service or 150,000 miles (240,000 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. For customer’s vehicles already outside of the above years and/or miles, we are still offering
reimbursement if the issue occurred within the years and miles stated above. Please follow the reimbursement steps
below.
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 already paid for repairs for the condition described in this letter, and those repairs were
completed prior to this mailing, 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 September 30, 2025, 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.
If you have any questions or need any assistance, please contact your dealer or the appropriate Customer Assistance
Center at the number listed below.
For the hearing or speech impaired, please contact our Customer Assistance Center using the Telecommunication
Relay Service by dialing 711 then providing the appropriate Customer Assistance Center number for your vehicle.
