Condition

Some customers may comment on seeing water leak into the interior, or wet carpet. This
condition could occur at either the front and/or rear, and on the right and/or left side.
Some electrical concerns or issues may occur, such as power locks cycle or are
inoperative after a car wash or rain in the XT5 and Acadia, or the liftgate actuator may be
noisy or inoperative in an XT6.
The cause of the condition may be possible "pin hole" voids in the roof panel to outer ring
laser braze and seam sealer. The pin holes are most commonly found near the top of the
windshield at the A - pillars, or the top of liftgate near the D - pillars. Examples of the leak
areas are shown below.

1. Visually inspect the front right and left roof laser
braze, then the rear right and left roof laser braze,
for pin holes or a crack.
2. Seal the holes/crack in any laser braze area
following the steps below:
2.1. Mix a small amount of *Kent Automotive
High-Tech Clear Seam Sealer, P/N 10200
(5 oz tube), or equivalent, WITH the proper
touch up paint color.
2.2. Avoiding excess sealer build up within the
ditch, work a small amount of the sealer into
the hole with a gloved finger.
2.3. Wipe away any excess sealer with a light
amount of solvent on a rag or paper towel.
The solvent will help the sealer flow into the
hole/crack.
3. Clean and dry any wet trim. Refer to Floor Carpet
Drying in SI.
4. Address and repair any electrical concerns as
necessary.

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.
