Recall Bulletin

F/CMVSS NONCOMPLIANCE RECALL
SUBJECT:

Electronic Park Brake Drag

MODELS:

2013-2015 Cadillac XTS
2014-2015 Chevrolet Impala

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 certain 2013 – 2015 model year (MY) Cadillac XTS and 2014
– 2015 MY Chevrolet Impala vehicles may fail to conform to S5.5 of Federal Motor Vehicle Safety
Standard (FMVSS) 135 (Brake system warning indicator). Some of these vehicles have a
condition in which the electronic parking brake’s piston actuation arm may not fully retract, which
may cause the brake pads to stay partially engaged with the rotor. In this condition, the parking
brake indicator may not illuminate even though the parking brake is engaged, which would
render a vehicle noncompliant with FMVSS 135.
In addition to the parking brake indicator malfunction described above, the driver may experience
poor vehicle acceleration, undesired deceleration, excessive brake heat, and premature wear to
some brake components. If the brake drag is significant or if the vehicle is operated for an
extended period of time in this condition, there is a potential for the rear brakes to generate
significant heat, smoke, and sparks.
CORRECTION
Dealers are to reprogram the electronic parking brake control module.

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
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 for this recall.
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.



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 EL49642 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 lights, exterior lights (including daytime running lights), HVAC, radio, etc.



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.

1. Reprogram the electronic parking brake (EPB) control module. Refer to the Electronic
Parking Brake Control Module Programming and Setup procedure in SI.

Traffic and Motor Vehicle Safety Act.
DEALER RECALL RESPONSIBILITY – For US and Export (US 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.
This bulletin is notice to you that the new motor vehicles included in this recall may not
comply with the standard identified above. Under Title 49, Section 30112 of the United
States Code, it is illegal for a dealer to sell a new motor vehicle which the dealer knows
does not comply with an applicable Federal Motor Vehicle Safety Standard. As a

consequence, if you sell any of these motor vehicles without first performing the recall
correction, your facility may be subject to a civil penalty for each such sale.
DEALER RECALL RESPONSIBILITY - All
All unsold new vehicles in dealer's 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.
In summary, whenever a vehicle subject to this recall enters your vehicle inventory, or is in your
facility 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.
