Condition
Some customers may comment that the roof panel flutters and/or there is a rattle noise from the roof or headliner when closing one of the side doors or
the liftgate.
Cause
This may be caused by the excessive motion of the roof panel. On initial inspection, you may notice that the roof panel expansion adhesive material has
separated between the roof and the roof bow. The concern is seen mostly on the first cross bow.
Correction
Lower the headliner assembly (it is not usually necessary to remove the headliner from the vehicle) to gain access to the roof bows. Refer to Headlining
Trim Panel Replacement in SI.
Remove any loose foam from the roof bow or bows. Apply Fusor super flexible anti-flutter foam-fast set, Fusor P/N 121/124, or equivalent, in a
continuous bead the entire length between the roof bow reinforcement and the roof outer panel.
Reinstall the headliner. Refer to Headlining Trim Panel Replacement in SI.
