Felt sticker (I ordered on Amazon) worked great for the seatbelt issue. Let us know what happens with the door noise (I have same issue).

Update: I took my car to the dealer and the worker said it was 'a known issue' (door noise). According to him, it has something to do with the connections between door and trim, which don't connect tight enough.. I don't know for sure if they actually replaced any parts, but they did put a felt liner between door and trim (they did all the doors at once, took them about 1h and 30 minutes). I'm glad to say the ticking is as good as gone. There are some more noises when driving over a (really) bad road, but I guess that's normal (I'm trying to not constantly focus anymore on every crack I hear). I think what I'm still hearing now and then is the seatbelt-connection on the side pillar.
It did suprise me how much noise our other (ICE) car (ford fiesta) actually makes when you pay attention to it. Most of it drowns in motor noise I guess.
But in conclusion: take your car to the dealer (or if you know what you're doing do it yourself), and get them to put a felt liner between door and trim. At least, it's going to be way better.

My dealer added some washers to the rubber bumpers on the tailgate which fixed the rattle for me - they said it was common

Do you have a picture of the rubber washers they added?

This is what one of them looks like, not entirely sure what's going on

Hmmmm..that looks like a quality item that should last for years....

Can you post a pic of what it looks like after the felt ?
Can you see it?
I'm thinking this was one thing the Bolt had too, maybe a hatch issue. I or a wad of toilet paper in a few spots and it stopped on the Bolt . But I don't want to go and do that on the Hi5

I’ve ordered some trim removal tools from eBay and when they arrive I’m going to take the door to pieces and get some felt in there. I’ve tried pushing pieces of card and paper in, but I think it needs a complete strip of felt to completely eliminate it. The bits of paper look ridiculous as well.

Here's a photo, you can see it at the top:

While this problem is solved, I do still have a lot of other 'noises' though:

1. Coming from the seatbelt retainer, tried putting some felt between pillar and seatbelt retainer, still needs some work but I think it's possible to get rid of it. It's already better now.
2. My dashboard makes a lot of squeeks and cracking noises (in my opinion), especially when it's warm outside, but it gets better when I drive for a little while..
3. Trunk occasionally rattles, but not all the time and not so loud
4. This is a new one, have it since it's sunny outside and the car gets warm (now my main frustration): the driver seat (only driver seat, passenger seat is fine) squeeks really loud with the slightest of movement (even when accelerating and braking). Sounds like freaking walking in the snow. Here's a sample.

Does anybody else have a very squeeky seat? Is this normal you think?
Don't know if I should make 'a thing' of it at the dealer..

I had this tiny on again/off again rattle in the rear. I don't think this one was the hatch.
Do you all see the 4 loops to hook some kind of aftermarket netting on ? on the lower sides? I put mine sticking straight out and have not heard that small rattle I noticed the other day. One of the hooks wiggled when I played with it and that was why I tried it. I need to listen again tomorrow on the ride into work and see if it's gone.

But hey, try it. Takes 2 seconds and you don't mess anything up

I hate rattles in cars. I collected my Ionic 5 Premium this morning, drove it the 12 miles home and all was well. Very impressed. I got my day’s work done and I thought I’d take the new car out for a run round the local lanes. I spent about an hour setting everything up and loading the carrier bag of miscellaneous car bits that I’d taken out of my old car yesterday into the Ionic.

No sooner do I get going and there’s a damn rattle coming from the boot. Marvellous. My first thought was that it must be something I’d put in or moved about in that underfloor area. I’ve progressively removed things until there is nothing in the boot at all and the rattle is still there. I’ve even taken out the parcel shelf thing and the false floor itself. I don’t think it is coming from the back seats or the seatbelts, so I’m at a bit of a loss.

I’m sure it wasn’t there on the way home this morning but I don’t see what I could have done to introduce it. I can’t be having this on a brand new car so it looks like I’ll be taking it back tomorrow!

Check your seat belts in the back seat, if the shoulder straps don't lay flat they rattle. Hopefully that is the issue you are having.

I may have a rattle coming from the passenger seat. When the road is bad, it looks as if the upper part of the passenger seat moves or vibrates laterally from left to right. But the seat seems tight and firm, I wonder if it's the seat or a cable under the seat hitting metal ? Anybody has this issue ?

On the hatch rattle-fix - One thing I did was get a white paint pen and put a small mark on both the barrel that screws out and the body that it screws into when it's fully screwed in.
Makes it easier to watch that both sides are then both screwed out the exact same amount - which I have found is helpful stopping the hatch rattle.

I have the same problem on my Ioniq 5 from new. It started when I drove out of the showroom over a bump! It has been back to the dealers twice but they have not found what is causing it. They are waiting for information from Hyundai. So annoying as the rest of the car is so good.

 

[drmonbowen]

Thank you everyone for your contributions to this thread! I didn't hear the sound until immediately after I installed the trailer hitch wiring kit. So I assumed that I had not done something properly or had omitted something important. But sure enough: the combination of winding the stops out and cleaning the door seal did the trick. For now, at least!

 

[rpeesel]

I’m just back from the dealers and I’m pleased to say the rattle is no more.

Their tech knew from my description almost straight away what was causing it so I don’t think this was his first rodeo. We had a quick run out so he could hear it for himself. We were both in agreement about the curse that is lane assist.

When we got back he applied some madly expensive lubricant to the rubber bushes on each side of the tailgate and that was it sorted. He says it is quite common for these to harden and then they rattle against the body of the car. I had a serene drive back with just the sounds of nature playing softly in the background.

Top marks to my local dealer for a speedy resolution of the problem.

Can you show a pic of the busings? I dont have my car yet, but I want to know what I am looking for in case it happens to me.
Do you know what lubricant?

Hi evryone.
So after 8 months struggling with the trunk rattling problem i think I finally got it solved.
So yes, the 2 stoppers on the trunk door need to be adjusted and it solved almost all the problem…. But it was coming back sometimes.
yesterday i was at my hyundai dealer and asked uf they had a solution from hyundai and he said still no.
But he told me another owner did another mod and it seems to have resolved the problem for good.

so here is the solution. You need to buy 4 bolt washers ( i bought those that do not rust) to the trunk door. 2 on each side like here.

and this solved the problem. No more noise at all!!!!!
Drove the car on bumps bad road etc… just to see if noise would come back. But no, the car sounds perfect now finally!!

i don’t understand why hyundai techs or engineers were not able to diagnose and come up with this solution and that it took people like us to try and fix there problem.

i hope this suits you well.

Copying my response from another thread in case anyone’s tailgate’s inner percussionist is coming out to play for the same reasons:

So…I think I solved my tailgate rattle.

I’ve had a progressively louder knocking and, eventually, squeaking rattle when going over uneven road surfaces for a while. I tried many of the common fixes:
- adjusting tailgate screw-in bumpers (to the point that the latch struggled),

• adding thicker washers under the rectangular bumpers higher up in the opening to get them to protrude more,
• adding thicker washers to the strike plate,
• wrapping latch in thick film
• adding foam padding in the latch compartment and around the tailgate mouth.

No fix.

Went to the dealer, they first “reseated the tailgate”, then ordered a whole new plastic trim panel because it was “inside the trim”.

A while ago, I noticed I can cause a similar rattle by “jigging” the tailgate up and down and side to side by hand when it’s open. When I did this, he noise was coming from the power lift gate strut mounting points. On a whim, I decided to try lubricating them, and suddenly, no more knocking.

Turns out, sand and dust got into the joints between the motorized trunk struts, the car body, and the tailgate assembly. I blew them out with compressed air and added a bit of silicone grease to each joint and to the strut cover edges were they slide into one another.

Voila, silence.

Be careful when tightening those bolts, they seem to be made of infant boogers and will strip if overtorqued even a little. Worse yet, the socket threads are cut straight into the sheet metal and will also strip, prompting a fun rethreading project. Ask me how I know.

I have been trying to solve the rattle since the car was new, almost 1 year now!
Having adjusted boot stops etc all solutions seemed to work initially then clunking came back.
My conclusion today is that it is 'play' in the powered strut that opens and closes the boot.....I found that when the boot was open, grasping the handle and moving the boot up and down slightly caused the same noise from the strut....a mechanical clank noise.
So yes adding spacers etc does change the movement of the boot when closed but the strut can still rattle......I have now tried some spray grease to inside the strut.....probably upset the dealer if they knew......still waiting to see if I have found a solution to the noise.
Othewise, nearly a perfect car!

After many attempts to find and resolve the rattle/clunking noise, and after many adjustments of the tailgate stops etc. I have found the problem that caused my noise and a solution.
I seems to be the powered tailgate strut that does the opening and closing…….and a piece of large pipe insulation on the static part has fixed the problem. See photo …..also a small piece on the unpowered strut.
