Recall Bulletin

FMVSS NONCOMPLIANCE RECALL
SUBJECT:

Front Brakes Lock During ABS, Stability Control, or Traction Control
Activation

MODELS:

2012 Chevrolet Volt

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 four 2012 model year Chevrolet Volt vehicles fail to conform
to Federal Motor Vehicle Safety Standards 135 and 126 for vehicle braking and electronic
stability control. The electronic brake control module (EBCM) in these vehicles does not
relieve the brake fluid pressure from the front brakes during an anti-lock brake system (ABS),
electronic stability control, or traction control event, which will cause one or both front brakes
to lock up and not release. This could cause a loss of steering control and/or increased
stopping distance, resulting in a crash. The front brakes will release upon ABS, stability
control, or traction control deactivation. Non-ABS braking is not affected by this condition.
CORRECTION
Dealers are to install a new brake pressure modulator valve.
VEHICLES INVOLVED
All involved vehicles are identified by Vehicle Identification Number on the Investigate Vehicle
History screen in GM Global Warranty Management system and are listed below. 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.

The General Motors Courtesy Transportation program is intended to minimize customer

Warranties. The availability of courtesy transportation to customers whose vehicles are within
the warranty coverage period and involved in a product program is very important in
maintaining 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

CUSTOMER NOTIFICATION
General Motors will notify customers of this recall on their vehicle by telephone and by letter, if
necessary.
DEALER RECALL RESPONSIBILITY – For US (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.
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. Recall follow-up cards should not be used for this
purpose, since the customer may not as yet have received the notification letter.
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.
