Bulletin No.: 16-NA-016
Cause
4363662
The cause of the locked condition may be either of the following:
• When the front seat is all the way back and the rear 60% seatback is lowered, the
added weight of the front occupant puts extra pressure on the seat belt bezel (1) and
button/stop (2). This may allow the seat belt to fully retract past the stop, and the
retractor may lock because there is not enough seat belt slack to unlock the retractor.
• A broken or missing seat belt button/stop on the rear center seat shoulder belt.
Correction
Service Procedure
DO NOT replace the shoulder belt assembly for this
condition until first attempting to disengage the
locking mechanism by following the
Recommendation listed below.
Recommendation
Pull hard on the locked webbing and then release. The
hard pull extracts a small amount of webbing from the
retractor which, in turn, permits a small amount of
retraction to occur when released. This is all that is
needed to disengage the locking mechanism. The
safety belt will now function properly.
In cases where the locking mechanism will not
disengage, cut the shoulder belt and replace the
shoulder belt assembly as directed in the Service
Procedure below.
4363664
Release the 60% seatback by carefully cutting the rear
center seat belt, then replace the rear seat center
shoulder belt assembly. Easier access to the seat belt
can be attained from the passenger side of the vehicle.

Note: The shoulder belt assembly service part may be
one of 2 different designs. The service part you receive
may, or may not, contain the mini button/stop (1)
shown in the graphic above, and either design is OK
to use.
Parts Information
Note: Use the vehicle identification number (VIN), SI,

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 equipment, tools, 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 GM dealer for information on whether your vehicle may benefit from the
information.
