Condition

Correction

Certain 2017 model year Buick Regal and Cadillac XTS vehicles may have a condition in which the overmold polymer material on the seat belt latch plate of the rear outboard seat belts may not allow the latch
plate to be properly inserted into the buckle, or may require excessive force for the buckle to latch. The
customer may be unable to buckle the seat belt.
Inspect, and if necessary, replace one or both rear outboard seat belt assemblies.

Service Procedure
1.

Pull the rear seat belt out of the retractor and align the latch plate with the buckle assembly.

2.

Insert the latch plate into the buckle until an audible click is heard. The latch plate should enter the buckle freely. The
click indicates that the buckle is latched.


If the latch plate cannot be inserted freely into the buckle, or if an audible click is not heard, replace the seat belt
assembly. Refer to Rear Seat Belt Retractor Replacement in SI.



If the latch plate enters the buckle freely and the click indicates that the buckle is latched, no further action is
required.

Dealer Responsibility
Whenever a vehicle subject to this service update enters your vehicle inventory, or is in your facility for service in the
future, and the vehicle is still covered under the New Vehicle Limited Warranty, you must take the steps necessary to be
sure the service update correction has been made before selling or releasing the vehicle.
All new, used, GM Certified Used, courtesy transportation vehicles, dealer shuttle vehicles, etc. in dealers' possession
and subject to this bulletin must be held and inspected/repaired per the service procedure of this bulletin before customers
take possession of these vehicles. Involved vehicles must be held and not delivered to customers, dealer-traded,
released to auction, used for demonstration, or any other purpose.
All GM Certified Used vehicles currently in the dealers’ inventory within the Certified Pre-Owned Inventory System
(CPOIS) will be de-certified and must be held and remedied per the service procedure in this bulletin. Upon submitting
an accepted/paid warranty transaction in the Global Warranty Management (GWM) system, the vehicle can be re-certified
for sale within the CPOIS system, or once again be used in the CTP program.

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.
