Recall Bulletin

PRODUCT SAFETY RECALL
SUBJECT:

Brake Booster Pump – Cavity Plug

MODELS:

2013 and some 2014 Cadillac XTS

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.
Vehicles involved in this recall were placed on stop delivery March 14, 2014. Once the service
procedure contained in this bulletin has been performed on the vehicle, the vehicle is released
from stop delivery and the vehicle can be delivered to the customer.
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 2013
and some 2014 model year Cadillac XTS vehicles. Pressure within the brake booster pump
harness may cause a brake booster pump cavity plug to dislodge from the connector. This could
allow contamination which may cause corrosion of the brake booster pump relay connector. If
there is sufficient corrosion of the relay connector, it may cause a resistive short and melt the
connector, which could cause a fire.
CORRECTION
Dealers are to ensure that the vacuum pump vent hose is re-routed so it cannot be restricted.
Silicone sealer is to be applied to increase the retention of the connector cavity plugs, and where
necessary, dealers are to replace the front body 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.

Bulletin No.: 14062

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
Parts required to complete this recall are to be obtained from General Motors Customer Care
and Aftersales (GMCC&A). Please refer to your “involved vehicles listing” before ordering parts.
Normal orders should be placed on a DRO = Daily Replenishment Order. In an emergency
situation, parts should be ordered on a CSO = Customer Special Order.
Important: Due to the small number of vehicles expected to require headlamp wire
harness and pump replacement and due to limited initial parts availability,
dealers are encouraged not to order parts for use as shelf stock. Parts should
only be ordered when inspection determines that replacement is necessary.
If the inspection determines that harness and pump replacement is required, they
are to be obtained from General Motors Customer Care and Aftersales (GMCC&A).
Orders should be placed on a CSO3 = Customer Special Order. All other
types will cancel.

CUSTOMER NOTIFICATION – For US and Canada
General Motors will notify customers of this recall on their vehicle.
CUSTOMER NOTIFICATION – For Export
Letters will be sent to known owners of record located within areas covered by the US National
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.
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. Recall follow-up cards should not be used for this purpose, since the
customer may not as yet have received the notification letter.

Page 12

March 2014

Bulletin No.: 14062

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.
