CUSTOMER SATISFACTION PROGRAM
SUBJECT:

ECM Wire Harness Contact

MODELS:

2014 Cadillac CTS
Equipped with 3.6L Twin-Turbo Engine (LF3)
THIS PROGRAM IS IN EFFECT UNTIL FEBRUARY 28, 2017.

CONDITION
On certain 2014 model year Cadillac CTS vehicles, equipped with a 3.6L twin-turbo engine (LF3),
the engine control module wiring harness may rub on the metal edge of the alternator bracket or
on a weld on the vehicle body rail. This condition could damage the wiring harness. If the wiring
harness is damaged, the Check Engine Soon lamp will illuminate, the vehicle may display
intermittent reduced engine power, or a fuse may blow and prevent the vehicle from starting.
CORRECTION
Dealers are to inspect and, if necessary, repair the wire harness. Dealers are to also install a new
design alternator bracket and install a mastic patch over the weld on the vehicle body rail.
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 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.
PART INFORMATION
Parts required to complete this program are to be obtained from General Motors Customer Care
and Aftersales (GMCC&A). Please refer to your “involved vehicles listing” before ordering parts.

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.

Dear General Motors Customer:
We have learned that on your 2014 model year Cadillac CTS, equipped with a 3.6L twin-turbo
engine, the engine control module wiring harness may rub on the metal edge of the alternator
bracket or on a weld on the vehicle body rail. This condition could damage the wiring harness.
If the wiring harness is damaged, the Check Engine Soon lamp will illuminate, the vehicle may
display intermittent reduced engine power, or a fuse may blow and prevent the vehicle from
starting.
Your satisfaction with your Cadillac CTS is very important to us, so we are announcing a
program to prevent this condition or, if it has occurred, to fix it.
What We Will Do: Your GM dealer will inspect and, if necessary, repair the wire harness. Your
dealer will also install a new design alternator bracket and install a mastic patch over the weld on
the vehicle body rail. This service will be performed for you at no charge until February 28,
2017. After that, any applicable warranty will apply.
What You Should Do: To limit any possible inconvenience, we recommend that you contact
your dealer as soon as possible to schedule an appointment for this repair. By scheduling an
appointment, your dealer can ensure that the necessary parts will be available on your
scheduled appointment date.
