PRODUCT SAFETY RECALL
SUBJECT:

Inspect Power Steering Hose Clamps

MODELS:

2015 Chevrolet Silverado 2500/3500 HD
2015 GMC Sierra 2500/3500 HD

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.
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 a defect which relates to motor vehicle safety exists in certain
2015 model year Chevrolet Silverado 2500/3500 HD and GMC Sierra 2500/3500 HD model
vehicles. Some vehicles were built with a power steering hose clamp that was not properly
attached to the power steering pump. If the vehicle is driven with the clamp not attached, the
hose may disconnect from the pump or gear, causing a loss of power steering fluid. This will
result in loss of power steering assist and Hydro Boost powered brakes without warning,
increasing the risk of a crash. The vehicle will revert to manual brakes and manual steering.
CORRECTION
Dealers are to inspect the power steering hose clamps in two locations to ensure that they are
properly attached.
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
Copyright 2014 General Motors. All Rights Reserved.

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 recall is a violation of law in several
states/provinces/countries. Accordingly, you are urged to limit the use of this report to the followup necessary to complete this recall.

Note: There are two designs for the power steering hose clamp. The first design clamp (A) has
an upright tab (1). Pull up on the tab (1) to release the pin and engage the clamp. The second
design clamp (B) has a horizontal tab (1). Push up on the tab (1) to release the pin and engage
the clamp. Refer to photograph. The power steering hose connection at the power steering
gear and pump will be secure (tight) if the clamp is engaged. A long telescope-style mirror and
light may be required to inspect the power steering hose clamps. Power steering fluid may be
present on the power steering hose, pump or gear if a clamp is NOT engaged.
3. Determine if the power steering hose clamps are engaged. Inspect the power steering hose
clamps connections at the power steering gear and power steering pump. Pull lightly on
the end of the power steering hose at the power steering pump and power steering
gear locations to ensure the hose is secure at the two locations.


If the power steering hose clamps are engaged at both the power steering gear and
pump locations, no further action is required.



If the power steering hose clamps are NOT engaged at the power steering gear and/or
pump locations, engage the clamp to secure (tighten) the hose connection. Proceed to
step 4.

4. Engage (tighten) the power steering hose connection at the power steering gear and/or
power steering pump locations.
5. Lightly pull on the end of the power steering hose at the power steering pump and/or power
steering gear locations to ensure the hose is secure at the two locations.
6. Lift and support the vehicle. Refer to Lifting and Jacking the Vehicle in SI.
7. Inspect the underbody of the vehicle around the power steering hose and power steering
gear and pump for evidence of a power steering fluid leak. If necessary, clean underbody of
vehicle and vehicle parts that are covered in power steering fluid.
8. Lower the vehicle. Refer to Lifting and Jacking the Vehicle in SI.
9. Check and, if necessary, add power steering fluid to the power steering system. Refer to
Checking and Adding Power Steering Fluid in SI.
10. Start the engine. Rotate steering wheel from left to right. Check for sign of cavitation or fluid
aeration (pump noise/whining). Refer to SI for diagnostic information and/or power steering
part replacement information, if required.
COURTESY TRANSPORTATION – For US and Canada
The General Motors Courtesy Transportation program is intended to minimize customer
inconvenience when a vehicle requires a repair that is covered by the New Vehicle Limited
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 provided at no
charge. Dealers should refer to the General Motors Service Policies and Procedures Manual
for Courtesy Transportation guidelines.

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. A copy of the customer letter is provided in this bulletin for your use in
contacting customers. 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.
