Condition

General Motors has decided to conduct a Voluntary Emission Recall involving certain 2019 Chevrolet Silverado and GMC Sierra vehicles with a 6.6L diesel engine.

If that occurred, the ECM may not accurately diagnose a fault in the auxiliary fuel tank system or the four wheel drive system. Further, the ECM may incorrectly report a fault or illuminate the malfunction indicator lamp (check engine light) on vehicles not equipped with these two systems.

Correction

Dealers are to reprogram the ECM.

DEALER RESPONSIBILITY

All new, used, GM Certified Used, courtesy transportation vehicles, dealer shuttle vehicles, etc. in dealers' possession and subject to this recall must  be held and inspected/repaired per the service procedure of this bulletin before  customers take possession of these vehicles. Involved vehicles must be held and not delivered to customers, dealer-traded, released to auction, used for demonstration, or any other purpose.

All GM Certified Used vehicles currently in the dealers' inventory within the Certified Pre-Owned Inventory System (CPOIS) will be de-certified and must be held and remedied per the service procedure in this bulletin. Upon submitting an accepted/paid warranty transaction in the Global Warranty Management (GWM) system, the vehicle can be re-certified for sale within the CPOIS system, or once again be used in the CTP program.

Dealers are to service all vehicles subject to this recall at no charge to customers, regardless of mileage, age of vehicle, or ownership, from this time forward.

Customers who have recently purchased vehicles sold from your vehicle inventory, and for which there is no customer information indicated on the dealer listing, are to be contacted by the dealer. Arrangements are to be made to make the required correction according to the instructions contained in this bulletin. A copy of the customer letter is provided in this bulletin for your use in contacting customers. Recall follow-up cards should not be used for this purpose, since the customer may not as yet have received the notification letter.

In summary, whenever a vehicle subject to this field action enters your vehicle inventory you must take the steps necessary to ensure the program correction has been made before selling the vehicle. In addition, for vehicles entering your facility for service, you are required to ensure the customer is aware of the open field action and make every reasonable effort to implement the program correction as set forth in this bulletin prior to releasing the vehicle.

OWNER LETTER

January 2020

This notice applies to your vehicle, VIN:  _____________________________________

Dear General Motors Customer:

This notice is sent to inform you that General Motors is conducting a voluntary emission recall that includes your vehicle.

Reason For This Recall:   Your 2019 model year Chevrolet Silverado or GMC Sierra vehicle, equipped with a 6.6 Liter, 8-cylinder diesel engine, may be equipped with an improperly functioning on-board emission-related diagnostic system that violates California and Federal standards and regulations. The vehicle's Engine Control Module (ECM) may have been reprogrammed during service with incorrect diagnostic software. If that occurred, the ECM may not accurately diagnose a fault in the auxiliary fuel tank system or the four wheel drive system. Further, the ECM may incorrectly report a fault or illuminate the malfunction indicator lamp (check engine light) on vehicles not equipped with these two systems

What We Be Done:  Your GM dealer will reprogram the engine control module. This service will be performed for you at no charge  . Eligibility for this service will not be denied solely due to your Chevrolet Silverado or GMC Sierra vehicle having non-GM parts or repairs performed by outlets other than a GM franchised dealer.

How Long Will The Repair Take?   Because of service scheduling requirements, it is likely that your dealer will need your vehicle longer than the actual service correction time of approximately 30 minutes.

What You Should Do:  Please contact your GM dealer as soon as possible to arrange a service date. Instructions for making this correction have been sent to your dealer. Please ask your dealer if you wish to know how much time will be needed to schedule, process, and repair your vehicle.

If you have any questions or need any assistance, just contact your dealer or the appropriate Customer Assistance Center at the number listed below.

Emission Law Information:  In order to ensure your full protection under the emission warranty made applicable to your vehicle by state and federal law, and your right to participate in future recalls, it is recommended that you have your vehicle serviced as soon as possible. Failure to do so could legally be determined to be lack of proper maintenance of your vehicle. Also, your vehicle may fail a state or local emission inspection or I/M smog check test if this recall is not accomplished.

IMPORTANT MESSAGE FOR CALIFORNIA RESIDENTS The California Air Resources Board (CARB) requires vehicle emission recalls be completed prior to California registration renewal. Uncorrected emission recalls will result in the inability to renew your California vehicle registration. At the time of emission recall completion, your California dealer will issue a "Proof of Correction Certificate". Keep this certificate and, if required, present it to the Department of Motor Vehicles when renewing your California registration as proof of recall completion.

We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your continued satisfaction with our products.
