SERVICE UPDATE
SUBJECT:

Service Update for Inventory Vehicles Only
SDM Stud Misalignment
Expires with Base Warranty

MODELS:

2016 Chevrolet Silverado
2016 GMC Sierra

Due to the special equipment needed to perform the required repair, all involved vehicles were
diverted by GM to a designated third party repair facility prior to delivery to final destination dealers.
Affected dealers should have been contacted by their District Manager-Aftersales (DMA) or a GM
representative advising of this necessary in-transit repair and the delayed delivery of the vehicle.
Vehicles involved in this recall were placed on stop delivery October 20, 2015 under the stop
delivery order for 15796. Vehicles in dealer inventory and customer vehicles were moved to safety
recall 15794. Vehicles that were contained at the vehicle distribution center or the plant, will
remain under this bulletin 15796.
This bulletin provides dealers with important information about submitting a warranty transaction
for floor plan reimbursement when a repaired vehicle arrives at a dealership.
PURPOSE
The Sensing and Diagnostic Module (SDM) on certain 2016 model year Chevrolet Silverado and
GMC Sierra vehicles needs to be replaced. These vehicles may have a small hairline crack in
one of the mounting feet securing the SDM to the floor pan of the vehicle. Under certain conditions,
the issue could potentially cause the SDM to not perform as intended. If the SDM does not perform
as intended, there may be a risk of occupant injury.
VEHICLES INVOLVED
All involved vehicles are identified by VIN in the Global Warranty Management System
Investigate Vehicle History Application. Dealership technicians 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.
Additionally, a list of involved vehicles currently in dealer inventory can be found in GlobalConnect,
under Departments, Service, Field Action Inventory Reports (US) or attached to the
GlobalConnect message (Canada) used to release this bulletin. Customer vehicles that return for
service, for any reason, and are still covered under the vehicle's base warranty should also be
checked for vehicle eligibility.

is not allowed. The amount of reimbursement should be charged as a net amount expense using

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.
