Chronology :
On August 2, 2022, GM opened a product investigation based on field data that indicated a relatively high rate of warranty returns alleging a loss of propulsion in 2019 model year Chevrolet Silverado 2500/3500 vehicles.
The investigation was later expanded to include additional model years, all diesel engine vehicle segments, and the GMC Sierra sister vehicle.
Between August 2022 and December 2022, GM analyzed warranty return information and field data claims potentially related to loss of propulsion in the subject vehicles. GM also met with GM internal fuel-system experts and suppliers. GM’s investigation ultimately identified a small segment of diesel vehicles in this investigation population—vehicles with the dual tank configuration—that appeared to be susceptible to debris blockage on the top of the rear fuel tank. Within this vehicle population, GM’s investigation identified approximately 1,600 tank or fuel pump module damage claims. The first claim was received by GM on June 12, 2017. GM is not aware of any accidents or injuries associated with this condition.
On January 26, 2023, GM’s Safety Field Action Decision Authority (SFADA) decided to conduct a safety recall on all 2017 – 2019 model year Chevrolet Silverado 2500/3500 and GMC Sierra 2500/3500 diesel trucks with the dual fuel tank configuration.

Dealer Responsibility – For USA & Export (USA States, Territories, and Possessions)
It is a violation of Federal law for a dealer to deliver a new motor vehicle or any new or used item of motor vehicle equipment (including a tire) covered by this notification under a sale or lease until the defect or noncompliance is remedied.
The US National Traffic and Motor Vehicle Safety Act provides that each vehicle that is subject to a recall of this type must be adequately repaired within a reasonable time after the customer has tendered it for repair. A failure to repair within sixty days after tender of a vehicle is prima facie evidence of failure to repair within a reasonable time. If the condition is not adequately repaired within a reasonable time, the customer may be entitled to an identical or reasonably equivalent vehicle at no charge or to a refund of the purchase price less a reasonable allowance for depreciation. To avoid having to provide these burdensome remedies, every effort must be made to promptly schedule an appointment with each customer and to repair their vehicle as soon as possible. In the recall notification letters, customers are told how to contact the US National Highway Traffic Safety Administration if the recall is not completed within a reasonable time.
Dealer Responsibility – All
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.
Dealer Reports – For USA & Export
For dealers with involved vehicles, a listing has been prepared and will be available through GM GlobalConnect Maxis Field Action Reports or sent directly to export dealers. The Inventory tab of the dealer reports will contain VINs that apply to this recall. This information is intended to assist dealers with the PROMPT COMPLETION of these vehicles. The Customer In-Service tab will contain customer names and addresses from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any purpose other than follow-up necessary to complete this recall may be a violation of law in several states.
Courtesy Transportation – For USA & Canada
Courtesy transportation is available for customers whose vehicles are involved in a product program and still within the warranty coverage period. See General Motors Service Policies and Procedures Manual for courtesy transportation program details.

Export – Letters will be sent to known owners of record located within areas covered by the US National Traffic and Motor Vehicle Safety Act. For owners outside these areas, dealers should notify customers using the attached sample letter.
Customer Reimbursement

See General Motors Service Policies and Procedures Manual, Product Field Action Customer Reimbursement Procedure (USA & Canada) or local Policies and Procedures, for details.
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.

To: All General Motors Dealers
On February 2, 2023, GM sent to all GM dealers GlobalConnect Message GCUS-3-2797 regarding safety recall N222368030.
The required repair to complete this recall is not yet available. Until further instructions are received, the involved vehicles that are in dealers’ possession (new or used vehicle inventory, GM Certified Used, courtesy transportation vehicles, dealer shuttle vehicles, etc.) must be held and cannot be delivered to customers, dealer-traded, released to auction, used for demonstration purposes or put to any other use.
This message is to inform dealers who have involved vehicles in their inventory that they can now apply for the used vehicle Working Capital Assistance Program (“WCAP”) for safety recall N222368030.
Before proceeding with the application process described below, dealers must verify vehicle eligibility based on the program terms and guidelines that were provided in GM GlobalConnect Message GCUS-9-10968 dated March 10, 2021. Applications submitted on ineligible vehicles are subject to chargeback of any incentives paid to the dealer under the WCAP. Because compensation and tracking requires visibility into dealers’ inventory, dealers must also have agreed to a Dealer Data Share agreement with GM in order to receive any compensation under this program.
To apply for the WCAP for safety recall N222368030, dealers must access the GM Global Warranty Management (GWM) system and submit a “ZSET” warranty transaction using the labor code provided below for each eligible vehicle. This zero dollar special transaction type is the dealer’s application for compensation and constitutes a representation from the dealer that the vehicle is eligible for WCAP assistance.
Note: Acceptance of the warranty transaction does not ensure vehicle eligibility or guarantee the provision of any assistance as defined by program terms and guidelines.

Description

Trans Code

Working Capital Assistance for Safety Recall N222368030
N/A
ZSET
To be eligible for the WCAP, a vehicle must be in dealer inventory at the time the related field action bulletin is released. If a vehicle has been delivered, wholesaled or otherwise disposed of prior to release of the bulletin, the vehicle is not eligible for assistance. Additionally, recalled vehicles taken in on trade may be eligible for assistance if the dealer immediately reports the vehicle in used vehicle inventory via its Dealer Management System (DMS) and makes application through the GWM system.
To ensure that GM is receiving daily inventory information, which is necessary to process payments and make eligibility determinations under the WCAP, the dealer’s vehicles must be properly identified in the dealership’s DMS. A daily feed of this information is provided to GM through the Dealer Data Share (DDS) agreement.
Beginning with the 1st quarter of 2019, all WCAP payments will be facilitated through the Global Warranty Management (GWM) system. For each eligible vehicle, a qualifying dealer will submit for WCAP vehicle enrollment with a “ZSET” transaction type and for reimbursement with a “ZFAT” transaction type both through the GWM system. If approved, a WCAP credit for that vehicle will be issued through the GWM system similar to any other warranty credit. WCAP submission instructions and the required labor code will also be provided in the appropriate field action bulletin. Each WCAP transaction being credited will be clearly identified on the dealer’s daily credit memo.
In order to receive payment, a dealer must have timely reported the vehicle in used vehicle inventory, retained the vehicle until the related field action bulletin is released, and properly applied for the WCAP payment. The vehicle must also be otherwise eligible under WCAP rules and guidelines.
GM reserves the right to amend, modify, terminate, or cancel this program at any time in its sole discretion.

Description of the Defect : General Motors has decided that a defect which relates to motor vehicle safety exists in certain 2017-2019 model year Chevrolet Silverado 2500/3500 and GMC Sierra 2500/3500 trucks with the diesel engine (RPO L5P) and the dual fuel tank (RPO N2N) configuration. In these vehicles, the rear fuel pump may not transfer adequate fuel to the front tank, which can cause a stall.
FMVSS 1 : NR FMVSS 2 : NR
Description of the Safety Risk : A vehicle stall could increase the risk of a crash.
Description of the Cause : If the tank vent in the rear fuel tank becomes clogged with debris, a vacuum effect created during fuel transfer could cause the rear tank to collapse. If this occurs, the system may not provide sufficient fuel to the engine. Identification of Any Warning
that can Occur : The driver may experience inaccurate or erratic fuel gage readings, engine stumble, a check engine light, and/or slow engine start. Involved Components : Component Name 1 : TANK ASM-AUX FUEL Component Description : Fuel Tank Assembly

Country : NR Chronology :
On August 2, 2022, GM opened a product investigation based on field data that indicated a relatively high rate of warranty returns alleging a loss of propulsion in 2019 model year Chevrolet Silverado 2500/3500 vehicles. The investigation was later expanded to include additional model years, all diesel engine vehicle segments, and the GMC Sierra sister vehicle. Between August 2022 and December 2022, GM analyzed warranty return information and field data claims The information contained in this report was submitted pursuant to 49 CFR §573 Part 573 Safety Recall Report 23V-047

The information contained in this report was submitted pursuant to 49 CFR §573
potentially related to loss of propulsion in the subject vehicles. GM also met with GM internal fuel-system experts and suppliers. GM’s investigation ultimately identified a small segment of diesel vehicles in this investigation population—vehicles with the dual tank configuration—that appeared to be susceptible to debris blockage on the top of the rear fuel tank. Within this vehicle population, GM’s investigation identified approximately 1,600 tank or fuel pump module damage claims. The first claim was received by GM on June 12, 2017. GM is not aware of any accidents or injuries associated with this condition. On January 26, 2023, GM’s Safety Field Action Decision Authority (SFADA) decided to conduct a safety recall on all 2017 – 2019 model year Chevrolet Silverado 2500/3500 and GMC Sierra 2500/3500 diesel trucks with the dual fuel tank configuration.
Description of Remedy :
Description of Remedy Program : Dealers will inspect the fuel tank and fuel pump module and replace them
if damaged due to this condition. Dealers will add a vent hose to all recalled vehicles’ rear tank assembly. Pursuant to 577.11, GM will provide reimbursement to owners for repairs according to the plan submitted on May 12, 2021. How Remedy Component Differs from Recalled Component :
Identify How/When Recall Condition was Corrected in Production : The added vent hose repositions the opening to an area that will reduce the opportunity for debris to clog the tank vent and cause this condition.
The vent hose was added to the fuel system design starting with 2020 model year 2500/3500 trucks. Recall Schedule :
Description of Recall Schedule : Dealers will be notified on February 2, 2023. Owner interim notification
is estimated to begin on March 24, 2023. Owner notification of an available remedy is estimated to begin May 17, 2023

Country : NR Chronology :
On August 2, 2022, GM opened a product investigation based on field data that indicated a relatively high rate of warranty returns alleging a loss of propulsion in 2019 model year Chevrolet Silverado 2500/3500 vehicles. The investigation was later expanded to include additional model years, all diesel engine vehicle segments, and the GMC Sierra sister vehicle. Between August 2022 and December 2022, GM analyzed warranty return information and field data claims The information contained in this report was submitted pursuant to 49 CFR §573 Part 573 Safety Recall Report 23V-047

potentially related to loss of propulsion in the subject vehicles. GM also met with GM internal fuel-system experts and suppliers. GM’s investigation ultimately identified a small segment of diesel vehicles in this investigation population—vehicles with the dual tank configuration—that appeared to be susceptible to debris blockage on the top of the rear fuel tank. Within this vehicle population, GM’s investigation identified approximately 1,600 tank or fuel pump module damage claims. The first claim was received by GM on June 12, 2017. GM is not aware of any accidents or injuries associated with this condition. On January 26, 2023, GM’s Safety Field Action Decision Authority (SFADA) decided to conduct a safety recall on all 2017 – 2019 model year Chevrolet Silverado 2500/3500 and GMC Sierra 2500/3500 diesel trucks with the dual fuel tank configuration.
Description of Remedy :
