trucks and Chevrolet Blazer, Traverse, Tahoe, Suburban, Buick Enclave, GMC Acadia, Yukon, Yukon

Chevrolet, Buick, GMC and Cadillac are updating all
consumer and dealer facing materials as appropriate.
This change to the availability of Wireless Phone
Charging is currently expected to remain in place until
further notice during the 2023 model year for all
impacted vehicles. As semiconductor chips become
available, GM will build certain vehicles with these
features.
Future retrofits for this feature will not be provided or
supported on these vehicles.
Therefore, dealers and customers should refer to the
vehicle invoice and the window label to understand the
features that are equipped on each individual 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 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.
