SERVICE UPDATE

SUBJECT: Service Update for Inventory and Customer Vehicles

Manual Shift Lever Loose

Expires with Base Warranty

MODELS: 2015-2016 Chevrolet Colorado

2015-2016 GMC Canyon

Equipped with Manual Transmission (RPO N8D)

This service update includes vehicles in dealer inventory and customer vehicles that return to the

dealership for any reason. This bulletin will expire at the end of the involved vehicle's New Vehicle

Limited Warranty period.

PURPOSE

This bulletin provides a service procedure to ensure the manual shift lever is properly secured to

the transmission stub shaft on certain 2015-2016 model year Chevrolet Colorado and GMC

Canyon vehicles equipped with a manual transmission (RPO N8D). These vehicles may have a

loose shift lever.

This service procedure should be completed as soon as possible on involved vehicles

currently in dealer inventory and customer vehicles that return to the dealer for any type

of service during the New Vehicle Limited Warranty coverage period.

VEHICLES INVOLVED

All involved vehicles are identified by VIN in the Global Warranty Management System –

Investigate Vehicle History Application. Dealership technicians should always check this site to

confirm vehicle involvement prior to beginning any required inspections and/or repairs. It is

important to routinely use this tool to verify eligibility because not all similar vehicles may be

involved regardless of description or option content.

Additionally, a list of involved vehicles currently in dealer inventory can be found in GlobalConnect,

under Departments, Service, Field Action Inventory Reports (US) or attached to the

GlobalConnect message (Canada) used to release this bulletin. Customer vehicles that return for

service, for any reason, and are still covered under the vehicle's base warranty should also be

checked for vehicle eligibility.

PART INFORMATION

No parts are required for this repair.

DEALER PROGRAM RESPONSIBILITY

Whenever a vehicle subject to this service update enters your vehicle inventory, or is in your facility

for service in the future, and the vehicle is still covered under the New Vehicle Limited Warranty,

you must take the steps necessary to be sure the service update correction has been made before

selling or releasing the vehicle.

All new, used, GM Certified Used, courtesy transportation vehicles, dealer shuttle vehicles, etc. in

dealers' possession and subject to this bulletin 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.

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.
