PURPOSE
This bulletin provides a service procedure to replace the liftgate actuator assembly on certain 2015

these vehicles may have been built with liftgate struts that can lock up and cease to move. If the
liftgate strut locks up, the customer may not be able to open or close the liftgate either
electronically or manually.
This service procedure should be completed as soon as possible on involved vehicles
currently in dealer inventory and customer vehicles that return to the dealer for any type
of service during the New Vehicle Limited Warranty coverage period.

M 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.
