Any of you have a headliner/sunroof noise issue?

[sethsquire]

Any updates on the rattle? Is it still gone? The more I hear this rattle, the more pissed I get! Embarrassing when you are taking someone for a ride and they ask you, "What is that sound?"....

I was away on my honeymoon for a bit, so I haven't had a chance to test it out recently. It did come back after it initially went away, so I stuck my hand up under the headliner again and tried to scrape the liquefied adhesive off the top of the headliner. The car was sleeping in my parent's garage during my honeymoon, where it was nice and cool,so it didn't pop up on my short drive home. Will update once we get another hot sunny day, because that's the real test.

I can tell you with almost absolute certainty that the noise (at least in my case) is related to the heat and the adhesive when it gets too hot. The issue with fixing it for the moment is limited access under the headliner, though if its not fixed by now I'll either (1) take it to the dealership or (2) start popping off the A- and B- pillar trim so I can legitimately drop the headliner and get at it properly. I have no doubt I could fix the issue if I had access to it.

Thanks for the update and congrats on getting married as well!
My "rattle" now sounds more like the sound of when you pull off a strip of velcro. This noise starts almost immediately at about 10-15 mph. This peeling velcro sound as best as I can describe it is just to the front of the grab handle on the passenger side. I tried pulling down on the grab handle as I drove and the sound lessened a bit. So I think you are correct about there being some sort of adhesive rubbing on something as the car moves and flexes.
Hopefully we will get to see some pictures of the inside of the headliner taken down from another member on here that was taking his in to the dealership for replacement

Headliners for other vehicles I’ve owned did not use any adhesive pookey to hold anything in place. Once you remove any grab handles, center roof console, any headliner lights, coat hanger holders and interior trim at the pilllers, the headliner normally just comes down. If Genesis has some form of adhesive in the headliner area, then removing the headliner without damage or a crease on the headliner becomes more challenging. I would think a wire loom, wire bundle, insulation material or something attached to the interior of the roof would be chaffing and making the noise when the interior is hot and the aforementioned items are more pliable than when cool. Pics of the first person to tackle this will be valuable to everyone.

I agree 100%, but the adhesive is definitely plausible. The intentions of the adhesive may be for another component, but could be a byproduct of the noise. I'm still waiting for my dealer to get the new headliner in before work can be done. Not sure they will allow me back to their workshop for insurance purposes, but I'm asking them if the can take pics.

Thanks for the update, @Tdefrees. Hopefully they'll take some pics.

I personally do not believe the rattle is from hot adhesive. This is a metal or plastic type of rattle. Adhesive that is rubbing should produce a "rattle". That just doesn't make sense. My roof rattle actually seems to lessen with heat. When cool from being in my garage, it starts rattling right away. After (typically) driving for 15-30 minutes the rattle disappears. Not always, but usually. It could very well be an issue of part expansion/contraction with outside/inside temperatures. That theory would make more sense. Stuffing more padding under the liner could only be masking/muffling the parts rattle. @Tdefrees, your dealership's dealing with the issue, however they do it, is going to be key. So I'm sure we're all really wanting to hear how your dealership resolves the rattle for good. The more info (and photos) the better.

Good insight all around. Although I can't see under the headliner (only get a hand up in there when I take off the weatherstripping) I can definitely feel some sticky substance in the area where the rattle is coming from. I don't think it's adhesive holding the headliner itself, but something that's up inside the headliner. Based on my experience, headliners typically have some clips and velcro straps holding them up.

When I temporarily fixed it before, I managed to scrape some of the sticky stuff out, and it came out looking like partially dried glue. I had initially used my finger to scrape it out of part of the area where the rattle was coming from, but it's hard to reach further in with my limited access.

As for dropping the headliner, I removed the grab handle and sunshade without issue, but I was reluctant to start yanking on the A-pillar trim for fear of breaking the clips that hold it. For what it's worth, when I removed the sunshade, I saw that the wiring connector that powers the light on the sunshade mirror is indeed coated in felt and seemed well insulated specifically to prevent against rattling.

Also, based on the descriptions here, I think it's highly possible that we have a couple of different sources of rattling going on. Mine is 100% heat related, as the thing is dead silent when its cool or cloudy, and I can't replicate it even by pressing directly on the source of the rattle. As for the sound itself, my now-wife described it as "sounds like someone crinkling a water bottle."

Today will be an excellent test when I leave work, because it's going to be sunny and very hot. I stuffed a piece of t shirt up there also, so maybe that'll help, or maybe not. Regardless, I have no doubt that the issue is solvable.

This thread is like a suspense novel. I can’t wait to see how it ends! Lol

I know, I can't wait until some finally "cracks" the case, especially after doing so much of my own research and running through so many different theories of what the rattle is. For now, I'm sticking with my adhesive/sticky stuff theory.

I would LOVE if they would get you some pictures of the underside of the headliner, just to see what I'm poking at when I stick my hand in there.

Bring your safety glasses so they can’t use that as an excuse and talk nicely to the service rep. I’ve had numerious dealers not have an issue with me in their shop if I questioned something being done or wanted to ask the technician a question during a repair. I think most technicians know there is that small group of folks like most on this forum (probably) who are the touchy feely type and need to see what is being done to their car. Your right about the insurance deal though being an excuse with some shops. I worry what those shops have to hide?

 

[CobraBob]

For those who think it is an issue with sticky stuff/adhesive and heat, do you believe that a sticky substance surrounding some metal or plastic parts is melting to the point where the parts start touching? It can't be sticky substances rubbing together because I can't see how that would produce a rattle. They're soft, not hard like plastic or metal. This is one very interesting thread folks. Hopefully we'll eventually be recipients of a solid remedy.

It's not so much as rattling but more of popping. Think about this, if you walk on a black tar surface in the shade on a 60 degree day, nothing happens. Walk on that same tarred surface that has heated up in the sun on a 90 degree day, you find your feet starting to stick and will "pop" as you walk. This is my poor attempt and generalizing this theory, but I feel it makes it plausible. Especially with the popping noise I am having. The two surfaces touch with the car flexing during movement, popping when they separate.

 

[Bourbonncigars]

The Tahoe/Yukon/Denali body used to have this issue. It was the adhesive that connected the side to side metal bracing to the roof. The adhesive would become separated and a rattle would appear when the sheet metal for the roof made contact with the bracing. Not sure if the G70 has anything like that up top, though.

 

[CobraBob]

@Bourbonncigars, you're more accurately describing the sound that most of us are hearing IMO. I know for sure my "rattle" is not a popping sound. Not even close to a popping sound. It's a definitive rattle from either metal or plastic pieces being loose. If it IS adhesive related, it is possibly a case where expansion and contraction of the adhesive is resulting in parts moving against each other when the car is in motion. Again, JMO.

I think of it as a couple screws loose and something shaking around a bit. Rattle for sure

A G70 service manual would help. Might give a visual of everything that could be a potential cause of the noise people are hearing.

Unfortunately the FSM leaves much to be desired in terms of detail on the headliner. No mention of the actual clips holding on the liner other than the pillar trim/panels and the roof handles. I want to post pictures of what I'm talking about here, but legally I'm not allowed to publicly post anything from the manual.

If anyone wants more detail please feel free to PM me and hopefully I can clarify things a little more.

This is what I hear as well, kind of like bubble wrap popping but not as loud. I get the noise most often when, say, turning into a parking lot. It puts a bending and twisting load on the car.

This issue makes me hesitant to buy/lease a G70. Just curious does anyone regret getting a G70 due to this issue?

I would hope the regidity of the chassis would prevent minor flexing and loading just from turning into a parking lot? All kinds of squeaks could come out if chassis flexed too easily. Not to mention handling would suffer when driven hard. I sure hope design wise the overall body integrity is up to snuff.

I dont have a sunroof and mine is quieter than any car Ive taken down my driveway. I dont think Ive ever heard a squeak
