Service Procedure
5187934
The purpose of this bulletin is to receive feedback from
the dealership technician. Prior to replacing the power
liftgate assist actuator, verify the liftgate actuator
grommet is properly seated to the sheet metal (1) with
NO gaps (2) which could result in water intrusion into
the liftgate. To check retention, pull down on each of the
4 corners individually to see if the clip is secured to the
sheet metal or if the grommet pulls away easily.
Copyright 2018 General Motors LLC. All Rights Reserved.
Visually inspect or feel the entire lip seal of the
grommet to check for proper seating. Please report
back any grommet issues that may have resulted in
water intrusion in the causal warranty verbatim or
submit a Field Product Report (FPR). For additional
information on the FPR process, refer to the latest
version of bulletin 02–00–89–002.

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.
