In case anyone else has the annoying headliner rattle above the driver's head (also sometimes happens on the passenger side as well) - here is the fix. It's caused by the roof beam support - usually the first one at the front of the truck. It has anti flutter foam in there from the factory, but when it gets cold outside sometimes the foam settles and/or they didn't use the proper amount when it was built. The fix is simple, pull down the headliner and put some blocks of foam in between the roof and the roof support beam.

My GM dealer subs out all their interior work to a local upholstery shop, it took them 2 hours to do the job. This TSB doesn't officially cover the 2011 model, but this is exactly what was wrong, and this fixed it.

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.


Condition/Concern:
Some customers may have a concern where the roof panel flutters when closing one of the front side doors. This may be caused by the excessive motion of 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.


Recommendation/Instructions:
To repair the concern, insert stiff foam blocks between the roof panel and roof bow to "pre-load" roof panel as show in the photo below.




Note: The protective foam block used on the doors of fullsize trucks during shipping from the assembly plant can be used.
