Recall Bulletin

PRODUCT SAFETY RECALL
SUBJECT:

Steering Assembly Bolt Not Properly Torqued

MODELS:

2014 Buick Regal
2014 Cadillac XTS
2014 Chevrolet Camaro, Impala

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 (include a tire) covered by this notification under a sale or lease until
the defect or noncompliance is remedied.
All involved vehicles that are in dealer inventory (new or used) must be held and not delivered
to customers, dealer traded, released to auction, 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 certain
2014 model year Buick Regal, Cadillac XTS, and Chevrolet Camaro and Impala vehicles. Some
of these vehicles may have fasteners that are not torqued to specifications at the interface of the
intermediate shaft and the steering gear and/or at the lower control arm to the lower ball joint. If
these fasteners are improperly torqued, they could back out and the vehicle could exhibit loss of
steering and lead to a crash.
CORRECTION
Dealers are to inspect the joints and verify the torque on the fastener.
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.

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.
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.
