This notice applies to your vehicle, VIN: _____________________________________
Dear General Motors Customer:
As the owner of a 2017-2018 model year Buick Encore, Chevrolet Sonic, or Chevrolet Trax, your satisfaction with our
product is very important to us.
This letter is intended to make you aware that some 2017-2018 model year Buick Encore, Chevrolet Sonic, or Chevrolet
Trax vehicles, equipped with a 1.4L Turbo Gas engine may have a condition where the turbocharger could fail. If this
condition occurs, the Malfunction Indicator Light (Check Engine Light) will illuminate and a diagnostic trouble code will
set. Additionally, the engine may run rough or have reduced power.
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 2017-2018 model year Buick Encore, Chevrolet Sonic, or Chevrolet Trax 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. 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 March 31, 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.
