Condition
This recall affects certain 2017-2019 model year Chevrolet Low Cab Forward 3500/4500/6500XD medium duty vehicles.

Dealer Responsibility
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.
Customer Notification
General Motors will notify customers of this recall on their vehicle (see copy of customer letter included with this bulletin).
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.

IMPORTANT SAFETY RECALL
October 2019
This notice applies to your vehicle, VIN: _____________________________________
Dear General Motors Customer:
This notice is sent to you in accordance with the National Traffic and Motor Vehicle Safety Act.
Isuzu Motors Limited has decided that a defect, which relates to motor vehicle safety, exists in certain 2017-2019 model year Chevrolet Low Cab Forward 3500/4500/6500XD medium duty vehicles. These vehicles are manufactured by Isuzu. As a result, GM is conducting a safety recall.
We apologize for this inconvenience. However, we are concerned about your safety and continued satisfaction with our products.
IMPORTANT
• Your vehicle is involved in GM safety recall N192263741.
• Schedule an appointment with your GM dealer.
• This service will be performed for you at no charge.
Why is your vehicle being recalled?
In some of the affected vehicles, the power supply bolt in the relay box may not have been properly tightened during harness production at the supplier. This may lead to melting of the power wire and/or a loss of electrical power to the vehicle, which can lead to an engine stall. If the bolt is loose, the vehicle could lose electrical power and stall while being driven, increasing the risk of a crash.
What will we do?
Your GM dealer will inspect and torque the power supply bolt in all affected vehicles. During the inspection, the harness and relay box will be checked for damage and any excess insulation. If there is any excessive insulation, the bolt will be removed, the excess insulation will be trimmed away, and the bolt will then be torqued to the appropriate specification. If the harness or relay box is found to be damaged it will be repaired or replaced. This service will be performed for you at no charge. Because of service scheduling requirements, it is likely that your dealer will need your vehicle longer than the actual inspection and service correction time of approximately 48 minutes, but additional time may be necessary.
What should you do?
You should contact your GM dealer to arrange a service appointment as soon as possible.
Do you have questions?
If you have questions or concerns that your dealer is unable to resolve, please contact the appropriate Customer Assistance Center at the number listed below.

STOP DELIVERY ORDER
Effective immediately, stop the delivery of certain 2017-2019 model year Chevrolet Low Cab Forward 6500XD Medium Duty Trucks in new or used vehicle inventory. Isuzu Motors Limited, the manufacturer of these vehicles, has notified the National Highway Traffic Safety Administration (NHTSA) about an upcoming safety recall that involves these vehicles. The GM recall number is N192263741.
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 until the defect is remedied.
Isuzu Motors Limited has decided that a defect, which relates to motor vehicle safety, exists in certain 2017-2019 model year Chevrolet Low Cab Forward 3500/4500/6500XD medium duty truck vehicles. In some of the affected vehicles, the power supply bolt in the relay box may not have been properly tightened during harness production at the supplier. This may lead to melting of the power wire and/or a loss of electrical power to the vehicle, which can lead to an engine stall. If the bolt is loose, the vehicle could lose electrical power and stall while being driven, increasing the risk of a crash.
To correct this condition, the relay box power supply bolt will be inspected and torqued in all affected vehicles. During the inspection, the harness and relay box will be inspected for damage, and any excess insulation. If there is excessive insulation, the bolt will be removed, the excessive insulation will be trimmed away, and the bolt will then be torqued to the appropriate specification. If the harness or relay box is found to be damaged it will be repaired or replaced.
Until further instructions are received, 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 not delivered to customers, dealer-traded, released to auction, used for demonstration purposes or any other dealer use. All GM Certified Used vehicles currently in the dealers’ inventory within the Certified Pre-Owned Inventory System (CPOIS) will be de-certified.
The Investigate Vehicle History (IVH) screen in the Global Warranty Management (GWM) system will be updated for this upcoming recall on September 10, 2019. This action has been taken to assist dealers with determining which vehicles are involved so they can properly respond to customer inquiries.
A list of involved vehicles that have been identified as being in dealer new vehicle
inventory is attached to this message. It is sorted by dealer Business Associate Code
(BAC) for easy reference. Your dealership’s BAC will not be listed if none of the
involved vehicles are currently in your new vehicle inventory. A file identifying involved
vehicles in dealer used inventory will be published in GM GlobalConnect, under the
Service tab in Field Action Inventory Reports.
Question and Answer Document (Q&A)
Attached to this message you will find a document that addresses the ten most likely
questions customers may have regarding this Safety Recall. Please use this information
as an aid to confidently answer customer concerns.
Until the recall bulletin is released, the Investigate Vehicle History (IVH) screen in the
Global Warranty Management (GWM) system will display “N/A” under Release Date
and “Incomplete – Remedy not yet available” under Status. This means the required
repair is not yet available and dealers should not attempt to perform any repairs.
We are working with the supplier to obtain the required parts as quickly as possible.
When a sufficient quantity of parts is available, the recall bulletin will be released, and
dealers can begin repairing vehicles.
