Description
1.5L Turbo Engine

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

The 1.5 L LFV engines in certain 2016 and 2017 model year Chevrolet Malibu vehicles may have a preignition condition that requires immediate repair. This condition may cause the engine to perform poorly,
misfire, run rough, and/or excessively consume oil. It may also illuminate the vehicle’s service engine
light. Over time, if not repaired, the condition can damage the vehicle’s pistons and engine.

Correction

Replace pistons.

Parts
Note: The piston and rod assembly referenced in this bulletin arrives with rod bolts that are allowed to be removed and
reused one time for final assembly to the complete repair.

Dealer Responsibility
All new, used, GM Certified Used, courtesy transportation vehicles, dealer shuttle vehicles, etc. in dealers' possession
and subject to this program 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, dealertraded, 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 program at no charge to customers, regardless of mileage, age of vehicle,
or ownership, through July 31, 2021. Customers who have recently purchased vehicles sold from your vehicle inventory,
and for which there is no customer information indicated on the involved vehicle 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.
In summary, whenever a vehicle subject to this program enters your vehicle inventory, or is in your facility for service
through July 31, 2021, you must take the steps necessary to be sure the program 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 program 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 program.
Courtesy Transportation – For USA & Canada
In this field action, GM is offering standard courtesy transportation while a customer’s vehicle is being serviced, even if
the vehicle is outside of the Warranty Coverage period. Dealers should refer to the 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 Customer Satisfaction Program based on the results of the
predictive analytic algorithm identifying that their vehicle should be included in this Customer Satisfaction Program on

their vehicle through their OnStar system via an in vehicle voice message (IVVM). In the event a customer cannot be
reached via IVVM, they will be contacted by the Customer Assistance Center.
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 July 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.

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.
