General Motors is releasing Service Update N252500161 today.

What Should Dealers Do: Dealers should review IVH or the Dealer Maxis reports
for open VINs in their inventory. Dealers can view the attached bulletin and it
will also be displayed in Service Information tomorrow.
A Stock VIN list is not included as our records show there are no vehicles in
dealer new inventory.
The Inventory tab of the Open Vehicle Report will contain Service Update Bulletin
VINs that apply to this field action. This information is intended to assist dealers
with the PROMPT COMPLETION of these vehicles. The Customer In-Service
tab will not contain Service Update Bulletin VIN data because the intent of a
Service Update Bulletin is to not inconvenience a customer with a special trip for
service. Service Update Bulletins are to be completed when the customer is in
for a regularly scheduled visit.

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.
