Headliner Issue - not the cloth, but whole thing sagging.

Headliner Issue - not the cloth, but whole thing sagging.
Have noticed that the headliner, not the cloth, but the whole thing is sagging a bit. When I push up on it, I can hear the sound of something sticky that was holding it up, like a tape or glue. It will stay in proper position for a few seconds then release and sag back down. Somewhat concerning because when I have the sunroof fully opened it sways up and down. I squeezed my hand under there to see what the factory secured it with, but couldnt figure it out. I fear that just your standard 3M automotive tape would fail given the weight of the headliner and the heat the inside of the vehicle produces. Plus the backing almost feels like cardboard. Has this happened to anyone, any non-messy permenent fixes? Have seen plenty of posts on the fabric sagging but nothing on this.

Yes. What has happened is the glue holding the Velcro pieces to the roof have failed. Then the Velcro stays together but the back side separates from the roof of the car allowing the head liner to sag a bit. You are correct the head liner backing looks to be a cardboard type material. It seems heat is the cause of the adhesive failure. You need to re-glue the Velcro that was attached to the roof. I had my head liner replaced under warranty and had this happen after the repair. It's hard to see but get a good flash light-maybe a LED one? Look in-between the moon roof opening and the head liner to see the Velcro pieces I am talking about. After the dealer repaired the Velcro it's been rock solid, even with the moon roof open and driving at speed.

Bull,
The well-known problem of headliner failure along with terrible harmonic distortion in the cabin when the moonroof is fully open are two primary reasons why we don't drive our S-Type at freeway speeds with the moonroof open. Above 40 to 45 mph, our ears can't stand the harmonic distortion. Closing the moonroof about halfway helps considerably. But by keeping the moonroof fully closed, I believe we'll preserve the headliner from failing for many years. Hope so, anyway. Yes, I know it sucks to have a feature that we can't use (driving at decent speed with an open moonroof), but that's the way it goes sometimes when you have to work around a design flaw....

Yep, you're right, 2 velcro blocks on each side of that plastic piece (looks to be some kinds of climate sensor or microphone). One is unglued from the top, the other unglued from the bottom, HEY at least the velcro is still connected......
Haha, thats amazing that they would do that. Its not even adhered metal to metal.......its metal to cardboard. Looks as though I'm going to have to try and slap some 3M double sided tape on the backing of those and also on that plastic piece. At least in the middle the tape will be adhered to hard plastic and metal. Still blows my mind how poorly a design this is. Clearly this will be a temp. fix given that it gets about 156 degrees F in my vehicle.

The plastic piece is part of the ARTS or smart airbag system. I got a heck of a squeak from that piece after the headliner replacement. I never could stop it and since I was out of factory warranty I asked the dealer anyway and they fixed it for free!! Momentum Jaguar in Houston. Good dealer service!
