Condition

Special
Coverage

Certain 2019 model year Buick Enclave and Chevrolet Traverse vehicles equipped with a 3.6L engine
(RPO LFY), and certain 2020 model year Buick Encore and Chevrolet Sonic / Trax vehicles equipped
with a 1.4L engine (RPO LUV), may have a condition that could cause the evaporative emissions
purge valve to not fully close. If this condition occurs, the engine could run rough, hesitate, or stall at
idle speeds. Additionally, the Malfunction Indicator Light (Check Engine Light) would illuminate, and
a diagnostic trouble code would be set.
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 June
29, 2023, 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 29, 2023, 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.

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

Dear General Motors Customer:
As the owner of a 2019 model year Buick Enclave or Chevrolet Traverse, or 2020 model year Buick Encore, Chevrolet
Sonic or Trax vehicle, your satisfaction with our product is very important to us.
This letter is intended to make you aware that certain 2019 model year Buick Enclave or Chevrolet Traverse, or 2020
model year Buick Encore, Chevrolet Sonic or Trax vehicles, may have a condition that could cause the evaporative
emissions purge valve to not fully close. If this condition occurs, the engine could run rough, hesitate, or stall at idle
speeds. Additionally, the Malfunction Indicator Light (Check Engine Light) would illuminate, and a diagnostic trouble
code would 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 2019 model year Buick Enclave or Chevrolet Traverse, or 2020 model year Buick
Encore, Chevrolet Sonic or Trax vehicle 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 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, 2024,
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.
