I noticed a rattle that was right behind the drivers head. It also occurs on the passenger side as well. with some pressure on the headliner then noise would go away.

I would notice the rattle when the temps were around 90F outside and the car had sat in the sun for a awhile. The passenger side starts at a higher temp, around 100F.

The driver side has been solved by the dealer. They found some spot(pinch) welds that were causing the problem. What ever they did, the noise is gone.

But, there was a downside. I have a few marks on the roof of the car from were they manipulated the metal. I have attempted to take pictures...but you cant see it. They are going to address this when I have it in to fix the passenger side.

I am fairly certain this was a similar noise that people were experiencing on the rear deck, just a different location.

I have had this issue since new. Subaru doesn't care to fix it.

I am the OP and still have it, but only on rough cement roads at highway speeds. Goes away if I push on the liner just above my head. Would love to get behind the liner and caulk the hell out of it so that it is attached to the roof. Maybe that would stop the vibration.

@GotM @Subie @BRZnutso my issue arose when i was testing out a new sub. i put it up too high and it set something loose and started the rattle.

just found a nice DIY to remove the front side of the headliner (basically depicts what @infinite012 described above): http://www.ft86club.com/forums/showthread.php?p=272101. followed it and shoved some weather stripping in there and it definitely helped. there was a raised portion that touches the roof of the car so i shoved it between that and the roof of the car. if i put it real loud i can still hear a little rattle but at regular listening levels the rattling has seemed to subsided.

the rear can be removed by popping out the plastic plug things at the rear of the car if you wanna take the whole thing off and dynamat it or something

I think I have this problem. I think I know how to fix it too. 3M Thinsulate Acoustic taped above the headliner; should dampen any vibrations, insulate heat and reduce low frequency noises. I'll report back when I decide to put it in (already bought).

Yes, I'm not sure what is loose, but it sounds like it's right overhead!

As the car is aging (now have 10K miles) the vibration/sound from the headliner seems to have gone. At least for now!

Relatable to this post!

I've got a similar or same headliner noise on my 2017 86.. more interior rattles for my "new" car (Still have the rear deck popping sound from another post http://www.ft86club.com/forums/showt...ht=wheel+noise).

My noise is also located right above the driver's head toward the back and goes away when I apply some upward pressure onto the headliner. The noise sounds almost like a loose screw on a hard surface, and only shows up when my car is on bumpier roads/highways where I'm going 70+mph probably due to some vibration. Didn't even know I had the new noise until the day I turned my music off.

Going to check out a Toyota dealer first and see if I can get a diagnosis cause this should fall under my warranty. If they can't solve it, I'm taking out my tools and following some guides!

Don't worry, mine went away at 10K miles on its own and never returned! (now 4 years later).
