Recall Bulletin

PRODUCT EMISSION RECALL
SUBJECT:

Knock Sensor Wiring Harness Connections Reversed

MODELS:

2013 Chevrolet Malibu
Equipped with 2.5L Engine (LCV)

This bulletin has been revised to provide the part number for the rear transmission
mount bolts, which require replacement. The service procedure has also been updated.
Please discard all copies of bulletin 12292.
CONDITION
General Motors has decided to conduct a Voluntary Emission Recall involving certain 2013
Chevrolet Malibu vehicles, equipped with a 2.5L engine (LCV). The wiring harness
connections for the knock sensors may be reversed. This could cause too much or too little
spark advance, causing pre-ignition or reduced engine performance and fuel economy.
CORRECTION
Dealers are to rework the wiring harness.
VEHICLES INVOLVED
All involved vehicles are identified by Vehicle Identification Number on the Investigate Vehicle
History screen in GM Global Warranty Management system. Dealership service personnel
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.
For dealers with involved vehicles, a listing with involved vehicles containing the complete
vehicle identification number, customer name, and address information has been prepared
and will be provided to dealers through the GM GlobalConnect Recall Reports. Dealers will
not have a report available if they have no involved vehicles currently assigned.
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.

open the harness in order to avoid wire insulation damage.

now be connected to knock sensor 2 (LH). The lead that previously connected to knock sensor
2 (LH) will now be connected to knock sensor 1 (RH). When the connector swap is completed,

In order to ensure full protection under the emission warranty, and the right to participate in

DEALER RECALL RESPONSIBILITY
All unsold new vehicles in dealers' possession and subject to this recall must be held and
inspected/repaired per the service procedure of this recall bulletin before customers take
possession of these vehicles.
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.
***THE FOLLOWING 2 PARAGRAPHS ARE NOT FOR CANADA OR EXPORT***
When a California emissions recall is completed by a GM dealer, the dealer must provide the
vehicle owner a “Proof of Correction Certificate” which the owner may need to present to the
California Department Of Motor Vehicles (DMV) when renewing their vehicle registration.
Without this correction certificate, the owner may be unable to renew their vehicle registration.
Additional Certificates can be obtained, at no charge, from Dealer Support Materials by
ordering on the web from the DWD Store, www.gmdealerworld.com, and then click on the
DWD Store link; request GM Item Number 1825 when ordering.

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.

while your vehicle is at the dealership for this repair. Please refer to your Owner Manual and

Emission Law Information: In order to ensure your full protection under the emission

IMPORTANT MESSAGE FOR CALIFORNIA RESIDENTS
The California Air Resources Board (CARB) requires vehicle emission recalls be completed
prior to California registration renewal. Uncorrected emission recalls will result in the inability
to renew your California vehicle registration.
At the time of emission recall completion, your California dealer will issue a "Proof of
Correction Certificate". Keep this certificate and, if required, present it to the Department of
Motor Vehicles when renewing your California registration as proof of recall completion.
