Any of you have a headliner/sunroof noise issue?

[AdriaticBlueG70]

Good news, I was able to fix almost every sunroof noise, including the popping noise when it's hot/sunny out. The basic logic of the fix found on Stinger forums still applies. There is a plastic and metal strip where the "foot" of the sunroof rests, and where the noises come from. The thing is, felt tape alone is not firm or thick enough for the weight of the sunroof at that corner, and so popping and rattle noises can still be heard. Therefore, I needed to find a more heavy-duty alternative.

I applied 3M 0634 Automotive Acrylic Plus Attachment Tape (double sided tape) to the parts of the photo with arrows, and that are circled in red. The tape is somewhat thick, and feels like a firm rubber compound. Then, on the sticky top of the double sided tape, I applied felt tape. Then, on top of the felt tape, I put on 3M PTFE tape, as it is super slick, to ensure that the sunroof doesn't drag any of this away when opening or closing. Please ignore the silicone goop in the photo, it's not mine, but from the Stinger forums, so I used it for illustration purposes. Overall thickness of the 3M tape, plus the felt tape, plus the 3M PTFE tape is slightly more than 3/16 of an inch, and does not make the sunroof stick out or anything, it remains just as level as before.

The results have been great. Now, I only hear a plastic-on-felt sound when a make a turn on a steep driveway, and the car body flexes, or going over some very rough patches of road. The annoying rattles and pops in everyday driving have been eliminated. Not perfect, but for the first time since buying this car, the interior feels somewhat solid and befitting a luxury car.

Hope this helps some of you.

Good to hear. The odd thing is why not every sunroof has this issue? Also, does the sunroof, after some amount of time, amount of use, exposure to heat, miles driven, what is the key that tips the scale to create noises? Adding extra material to areas like you did would imply a possible part tolerance issue maybe or something just wears out quickly?

I think it’s definitely tolerances that get aggravated by temp changes. This car isn’t put together to something like Japanese standards when it comes to things like gaps (as my skewed driver’s side door constantly reminds me). Before this sunroof fix, I could press down on that corner of the sunroof from the outside and feel a clunk. Now it feels solid. When the sunroof is very hot, I could feel a tiny movement, but since it’s contacting that double sided tape+felt tape, there’s no sound. Good enough for now.

Thanks for the info. Nice work!

Good sleuthing I will definitely keep this in mind when The Noise rears its ugly head again. Up until now, it's been blissfully quiet all winter since I employed the t-shirt method.

T shirt method? I am intrigued. I tried to do what Kirk did with the foam blocks, but I think I misread the diagram he provided, as I see no improvement. Did you just stuff a t shirt in between the headliner and the roof through the opening around the sunroof area? If so, did you pull disconnect the velcro parts of the liner that attach it to the roof?

I pulled down the window weatherstripping on the passenger door and stuffed a shirt tightly into the headliner into the area where the headliner creases near the sun visor. I'll try to take a picture when I'm near the car again. The idea is that the extra padding increases tension on the headliner in the problem area and makes it less prone to flexing. Not an exact science by any means...

Would love to see a picture if you have the time. I plan on stuffing 3M Thinsulate in that area soon.

So I'm pointing at the area where the bulk of the t-shirt stuffage took place. The empty hole is where I removed the grab handle while trying to diagnose the problem initially, for reference.

Basically, just peel off the weatherstripping on the top of the door, and you can slide your fingers under the airbag into that area where the headliner creases. One of the things I noticed when I was doing that and it was very hot was globs of sticky adhesive goo, which I tried my hardest to claw out with my fingernails. I believed (and still believe) that this is the source of the heat related crackling; basically the headliner sticking and unsticking to it as it flexes in normal driving. With respect to my specific noise, you could make it stop by pressing and holding that same area while driving, so I was trying to devise a way to replicate that sustained pressure without having to drive around pressing on my roof like a dunce.

I stuffed the t-shirt TIGHT into that little area where I'm pointing to minimize any flex in the headliner, and positioned some of the excess fabric leading from that location along the edge that leads into the a-pillar trim. I can't really photograph it since it's under the headliner, but once you get your hand under there you'll get the idea.

It hasn't gotten super hot here, but it was definitely warm yesterday (almost 80) and I didn't hear anything as I was driving, so fingers crossed it stays that way.

Edit: Slight clarification, with the grab handle in place, the spot I'm pointing at becomes sort of a little "channel" in front of that ridge. When stuffing the shirt in there, I did my best to feed the fabric into said channel as tight as possible. It's hard to describe, but you'll understand if your fingers are feeling around in there.

Thanks! Just to clarify, should the grab handle be unscrewed and removed when I do this, like you have in the picture?

Hey sorry for the delay. You don't have to remove the grab handle, I don't think there's any benefit to doing so. I had just done it when I was trying to track down what the noise was.

Well, sure enough as the t-shirt trick seems to be holding for the hot weather-sticky sound, my stupid sunroof seems to have developed its own signature rattle, as described.

I don't have the various types of tape you described, but I do have some sticky-back felt, so I'm going to try and apply to the areas you helpfully pointed out in the pictures to see if that alleviates the issue. I assume the dealer is just going to be a waste of time on this issue as well.

My noises actually came back as the weather got into the high 80’s. I went on a very extended test drive with a dealer tech, and they agree there is an issue. It’s been in the shop since May 15th. They got a new sunroof glass unit, but let me know that the noise is still there. They now pulled a G70 off the showroom floor, and taking the sunroof rail guides off it to put into my car instead, to see if it helps. No clue how long it will all take.

Seems like this probably affects most G70s with a sunroof. Some owners may not notice, and some may live in areas with more favorable weather, though.

Well that's not very encouraging... this is certainly a new noise for me, as distinct from the headliner noise, which is also exacerbated by heat. I can replicate it by pressing down on the outside or from the inside, pretty much exactly as described in this thread on the stinger forum: Sunroof Rattle Fix

I'm going to think positive and try some felt regardless.

 

[AdriaticBlueG70]

My car has been at the dealer since May 15th. I got a call saying none of their fixes worked, and that the factory will be sending them an entirely new sunroof casette/assembly. This will require taking apart the interior, taking apart either the front or back window (possibly both), and fully dropping the headliner. I am not pleased at all. They never can put the car back together quite the right way when they do that.

That's definitely not confidence-inspiring... I just dropped off my car at the dealership for them to look at it today, along with some brake vibration at higher speeds (warped rotors?). I asked the service advisor if he was going to drop the headliner to look and he said it was likely. I'm worried that's going to mess up the delicate balance of the t-shirt fix which has alleviated that OTHER noise that was coming from the headliner.

At least they gave me a 3.3 sport loaner on sticky-icky summer tires. There's a NOTICEABLE handling difference between this and the lame 18 inch all seasons that came on my own car. I also tried out the adaptive suspension but I don't think I really see a difference there.

Lucky! My loaner this time is an Elantra. The engine sounds like a mix of coffee grinder and vacuum cleaner under load. Otherwise, it feels surprisingly solid for such an inexpensive car.

For the issues I've had, I must admit that Hyundai makes great cars all the way across the lineup. The first time I brought the car in I had a Kona 1.6T loaner for three weeks, and I did enjoy it. I think an Elantra Sport with that engine and a manual would be a fun jaunt.

I get the sense that there was a corporate directive of some sort (at least at my dealership) where they told the staff to start treating Genesis owners better than the average Hyundai service customer. The last two service appointments were super smooth and there were Genesis loaner cars waiting when I got there, although this one is absolutely covered in dog hair, which annoys me because my wife is allergic to dogs, cats, and all manner of other furry beasts (myself, excluded).

Scary stuff. Others on here have had the entire sun roof replaced and I think the lasting results are mixed. Your interior will be gutted for sure along with some glass removal to slide the headliner out. If you could get some good pics of the interior of the roof that would be handy to share. A couple of pics of the 3rd brake light wiring colors would help me tremendously on a project I have going. You may have to insist you want to see your car for some dealers are real anal about folks in the service area. Anytime I’ve had work done dealers at first say no and after some pushing they have let me in the service area to see the car or ask the technician a question. Hope everything works good for you. Keep us informed.
