Recall Bulletin

PRODUCT SAFETY RECALL
SUBJECT:

Inaccurate Fuel Level Readings

MODELS:

2014 Buick Enclave
2014 Chevrolet Traverse
2014 GMC Acadia

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.
All involved vehicles that are in dealer inventory must be held and not delivered to
customers, dealer traded, or used for demonstration purposes until the repair contained
in this bulletin has been performed on the vehicle.
CONDITION
General Motors has decided that a defect which relates to motor vehicle safety exists in some
2014 model year Buick Enclave, Chevrolet Traverse and GMC Acadia vehicles. A calibration in
the engine control module (ECM) may result in inaccurate fuel gauge readings at both the high
and low end of the fuel range by as much as one quarter of a tank. If the fuel gauge wrongly
indicates more fuel than is actually present, the customer can run out of fuel. If a customer runs
out of fuel while driving, the vehicle will stall, increasing the risk of a crash.
CORRECTION
Dealers are to reprogram the ECM with a new software calibration.
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 US and Canadian dealers through the GM GlobalConnect Recall Reports, or
Copyright 2014 General Motors. All Rights Reserved.

sent directly to export dealers. 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 followup necessary to complete this recall.
PART INFORMATION
No parts are required.
SERVICE PROCEDURE
Note: Carefully read and follow the instructions below.


Do NOT attempt to order the calibration number from GM Customer Care and Aftersales.
The calibration numbers required for this service procedure are programmed into control
modules via a Multiple Diagnostic Interface (MDI) with the calibration update. If you cannot
access the calibration, call the Techline Customer Support Center and it will be provided.



DO NOT program a control module unless directed to by a service procedure or a service
bulletin. If the control module is not properly configured with the correct calibration software,
the control module will not control all of the vehicle features properly.



Ensure the programming tool is equipped with the latest software and is securely connected
to the data link connector. If there is an interruption during programming, programming failure
or control module damage may occur.



Stable battery voltage is critical during programming. Any fluctuation, spiking, over voltage
or loss of voltage will interrupt programming. When required install the EL-49642 SPS
Programming Support Tool to maintain system voltage. If not available, connect a fully
charged 12 V jumper or booster pack disconnected from the AC voltage supply. DO NOT
connect a battery charger.



Turn OFF or disable systems that may put a load on the vehicles battery such as; interior 8



During the programming procedure, follow the SPS prompts for the correct ignition switch
position.



Clear DTCs after programming is complete. Clearing powertrain DTCs will set the
Inspection/Maintenance (I/M) system status indicators to NO.



Note the engine oil life remaining percentage.

To reprogram an existing K20 Engine Control Module, perform the following procedure:
1. Install EL-49642 SPS programming support tool.
2. Access the Service Programming System (SPS) and follow the on-screen instructions. Refer
to Service Programming System (SPS) documentation in SI for programming instructions.
3. On the SPS Supported Controllers screen, select K20 Engine Control Module - Programming
and follow the on-screen instructions.
4. Clear DTCs after completing the programming procedure.

Warranties. The availability of courtesy transportation to customers whose vehicles are within
the warranty coverage period and involved in a product program is very important in maintaining
customer satisfaction. Dealers are to ensure that these customers understand that shuttle
service or some other form of courtesy transportation is available and will be provided at no

DEALER RECALL RESPONSIBILITY – For U.S. and Export (U.S. States, Territories,
and Possessions)
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 RECALL RESPONSIBILITY – All
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.

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.
