SITUATION
This bulletin outlines multiple known areas of possible water entry for the vehicles listed above. It serves
only as a diagnostic resource in troubleshooting water leak complaints from the roof area.
This bulletin does not include all potential areas of water entry from the sunroof. Additional diagnosis may be
required for vehicles which are not affected by the scenarios outlined below.

CAUSE
The following situations are known to be potential causes for water entry into the vehicle from the sunroof
area:
Incorrect adjustment of sunroof glass panels
Damage to the sunroof “perimeter seal” mounted to the roof
Misplaced or damaged support foam for the center drip tray
Damaged side seals of the rear sunroof glass panel

Improperly installed, clogged, or kinked panoramic sunroof drain(s)

CORRECTION
Follow the procedures listed in the table below to inspect and/or repair the outlined areas.

PROCEDURE
Area of possible water intrusion:
Incorrect adjustment of sunroof glass panels
Reference ISTA for specific repair instructions for adjustment of the sunroof glass panels based on the
specific model of vehicle being worked on.
Sunroof glass inspection and adjustment should always be a starting point when investigating water
intrusion from the roof area.
Note: A vehicle’s sunroof and drains are ONLY capable of draining up to a certain volume of
water. Excess water allowed to enter the sunroof can overflow into the vehicle. This is not always a defect
in the vehicle’s ability to drain the water, but can also be attributed to too much water being allowed to
enter the sunroof (i.e, improperly adjust sunroof glass panels, faulty seal, etc).
Damage to the sunroof perimeter seal mounted
to the roof

This typically occurs in the corners.
Additional damage may include indentation or
deformity at any point of the perimeter seal.

Misplaced or damaged support foam for the
center drip tray
Photo shows correct (green) vs incorrect (red).
If the foam has become misplaced:

Correctly position support foam, operate
sunroof 5 times, and check to ensure
proper position remains.
Replace foam if found out of place after
operation.

If the foam is missing or damaged:

Replace support foam, ensuring proper
installation as shown to the left.

Damaged side seals of the rear sunroof glass
panel
Note the gap and incomplete installation of the
side seal (long arrow; passenger side shown,
looking rearward).
If the seal is incorrectly installed:

Replace the glass panel side seals.

Improperly installed, clogged, or kinked
panoramic sunroof drain(s)

Position the vehicle on a flat surface
Familiarize yourself with which sunroof
“track” is used for water
management. Ensure water is ONLY
introduced to the water management
track of the sunroof.

Introduce approximately 300ml of water
to each drain tube and compare drainage
speed at all the tubes.
If water enters the vehicle during testing, or one
drain tube is slower than the others, remove the
corresponding interior trim as needed to
investigate causes of potential blockages.
Note: A borescope can be a useful tool for
investigating the front hoses in the A-Pillar area.
If a kink is unable to be removed or the hose is
damaged beyond reforming, reference the
attachment for one potential type of repair which
could be completed in certain scenarios.
If a front drain hose requires replacement, submit
TSARA case for additional assistance due to
replacement complexity.

PARTS INFORMATION

resource. Refer to ETK/AIR.

WARRANTY INFORMATION
Warranty defect code and labor operations will depend on the specific repairs made to each vehicle. This

Note: Appropriately sized plastic inserts will need to be sourced locally.

•

Place the plastic insert inside the
drain tube, as shown.

•

Roll back the drain tube and apply a
piece of butyl between the plastic
insert and the tube.

•

Note: The butyl must wrap
complete ly around the insert.

•

Unroll the drain tube and apply a tie
wrap over the drain tube in the area
of the butyl and the insert.

•

The tie wrap must be installed in the
orientation shown. This will eliminate
any possible interference when the
headliner is reinstalled.

•

Install the tube with the plastic insert
into the other end of the drain tube
and perform the same connection
procedure with butyl and tie wrap.
