Product Safety Recall
N182204190 Chassis Cab Truck Fuel Leak

Release Date:    September 2019                                                    Revision:    02

Revision Description: This bulletin has been revised in the Parts, Warranty Information, and Service Procedure sections. The correction statement has also been updated to capture these changes. Please discard all previous versions of N18220419.

Involved vehicles are marked “open” on the Investigate Vehicle History screen in GM Global Warranty Management system.  This site should always be checked to confirm vehicle involvement prior to beginning any required inspections and/or repairs.   

Condition

General Motors has decided that a defect, which relates to motor vehicle safety, exists in certain 20162018 model year Chevrolet Silverado 3500 and GMC Sierra 3500 vehicles equipped with gas engines (L96) and dual fuel tanks (N2N).  In these vehicles, if the fuel-level sensor in the front tank becomes stuck in a low-level position, the rear tank may overfill the front tank and potentially cause it to expand.  In rare circumstances, the front fuel tank could expand and contact a moving drive shaft, which could create a hole in the front fuel tank and allow fuel to leak. If leaked fuel encounters a potential ignition source, a fire could occur.

Correction

Dealers will replace the rear-tank fuel-pump module with a pump that has a lower pressure limit, as well as updating the ECM calibration. Dealers will also inspect the front tank and replace if necessary.

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 recall enters your vehicle inventory or is in your dealership for service in the future, you must take the steps necessary to be sure the recall correction has been made before selling or releasing the vehicle.

Dealer Reports

For dealers with involved vehicles, a listing with involved vehicles has been prepared and will be provided to U.S. and

Canadian dealers through the GM GlobalConnect Recall Reports or sent directly to export dealers.  The listing may contain customer names and addresses obtained 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 is a violation of law in several states/provinces/countries.  Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete this recall.

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, Sections 1.4 and 6.1.10, for courtesy transportation program details.

Customer Notification

USA & Canada – General Motors will notify customers of this recall on their vehicle (see copy of customer letter included with this bulletin).

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

Customer requests for reimbursement of previously paid repairs to correct the condition described in this bulletin are to be submitted to the dealer prior to or by August 31, 2020.  See General Motors Service Policies and Procedures Manual, Section 6.1.11 – Product Field Action Customer Reimbursement Procedure (USA & Canada) or local Policies and Procedures, for details.
