CUSTOMER SATISFACTION PROGRAM
SUBJECT:

Windshield Water Leak

MODELS:

2012 Buick Verano

THIS PROGRAM IS IN EFFECT UNTIL MAY 31, 2015.
CONDITION
The windshield on certain 2012 model year Buick Verano vehicles may not be completely
sealed to the body at the lower left side of the windshield. Water could leak into the vehicle at
this point and drip onto the body harness connector, causing corrosion on the terminals or
shorting between terminals. Depending on the terminal(s) involved, it could cause one or more
of the following conditions: automatic OnStar® emergency calls, flashing of the park brake light,
rough engine operation, improper air conditioning system operation, illumination of the Service
Engine Soon light, and other malfunctions.
CORRECTION
Dealers are to perform a water test to detect a water leak. If a leak is found, dealers are to
reseal the area and perform another water test. If leaking is still present, the windshield is to be
reinstalled. If evidence of a leak is found, the connectors are to be inspected to determine if any
terminals are corroded. Corroded terminals are to be replaced.
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.

COURTESY TRANSPORTATION – For US and Canada

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
charge. Dealers should refer to the General Motors Service Policies and Procedures Manual for

In summary, whenever a vehicle subject to this program enters your vehicle inventory, or is in
your facility for service through May 31, 2015, you must take the steps necessary to be sure the
program 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.

Dear General Motors Customer:
We have learned that the windshield in your 2012 model year Buick Verano may not be
completely sealed to the body at the lower left side of the windshield. Water could leak into the
vehicle at this point and drip onto the body harness connector, causing corrosion on the
terminals or shorting between terminals. Depending on the terminal(s) involved, it could cause
one or more of the following conditions: automatic OnStar® emergency calls, flashing of the
park brake light, rough engine operation, improper air conditioning system operation,
illumination of the Service Engine Soon light, and other malfunctions.
Your satisfaction with your Buick Verano 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 perform a water test on the windshield to detect a water
leak. If a leak is found, your dealer will reseal the area and perform another water test. If a
water leak is still present, the windshield will be reinstalled. Also, if evidence of a leak is found,
the connectors will be inspected to determine if any terminals are corroded. Any corroded
terminals will be replaced. This service will be performed for you at no charge until May 31,
2015. 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.
If you have any questions or concerns that your dealer is unable to resolve, please contact the
appropriate Customer Assistance Center at the number listed below.
