CUSTOMER SATISFACTION PROGRAM
SUBJECT:

Electronic Power Steering Loss of Power Assist

MODELS:

2014 Chevrolet Caprice, Caprice PPV
2014 Chevrolet SS

CONDITION
Certain 2014 model year Chevrolet Caprice, Caprice PPV and SS vehicles equipped with
electric power steering (EPS) may experience a sudden loss of power steering assist that could
occur at any time while driving. If the power steering assist is lost, a message is displayed on
the Driver Information Center (DIC) and a chime sounds to inform the driver. Steering control
can be maintained, as the vehicle will revert to a manual steering mode, but would require
greater driver effort at low vehicle speeds. This condition is likely to be intermittent, the steering
usually returns to normal next time the car is started.
CORRECTION
Dealers are to inspect the electrical connector at the steering gear control module and install
dielectric lubricant to the module terminals.
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 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.

All unsold new vehicles in dealers' possession and subject to this program must be held and
inspected/repaired per the service procedure of this program bulletin before customers take
possession of these vehicles.
Dealers are to service all vehicles subject to this program 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 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. A copy of the customer letter is provided in this bulletin for

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.
