SB-10057272-1285 GM Bulletin No.: 14688 Date: January 2015 Service Bulletin SERVICE UPDATE SUBJECT: Service Update for Inventory and Customer Vehicles Engine Bearing Bedplate Mismatched to Engine Block Expires with Base Warranty MODELS: 2015 Chevrolet Malibu, Impala Equipped with 4 Cylinder Engine (RPO LKW) 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 inspect engine bearing bedplate and engine block serial numbers on certain 2015 model year Chevrolet Malibu and Impala vehicles equipped with a 4 cylinder engine (RPO LKW) to ensure that they match. If the serial numbers match, no further action is required. If the serial numbers do not match, the engine must be replaced. 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 on the Investigate Vehicle History screen in the Global Warranty Management system. 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 verify vehicle 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 is available on the “Service Update Bulletin Information” link under the “Service” tab in GM GlobalConnect (U.S.) 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. Copyright 2015 General Motors.

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. 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. We Support Voluntary Technician Certification
