You sure the seatbelt buckle has not twisted round and the metal is tapping the trim?

 

That was one of my first thoughts having experienced this on my first test drive. Neither of them appear to be twisted and I’m sure the rattle is coming from further back.

I’ve just had to go out and disable the “advanced intruder alarm” in the settings of the car as the alarm has gone off twice in the last hour for no apparent reason. It’s not turning out to be a very good first day.

 

Just to be sure I’ve just been for a quick whizz round the block with both the outer rear belts plugged in. No change sadly.

Earlier I literally stripped the boot and its contents so I’m sure it’s none of those causing it. I‘ve just been having a prod around at anything that could move about and all I can really find is on each side of the tailgate there is a rubbing strip. These will move about and they make a noise a bit like the rattle I’m getting when I do so by hand.

 

I would bring it to the dealer and have them check it out. I remember when I had got my Nissan Juke back in 2010. There was a rattle from underneath the dash. The dealer was never able to fix it and it drove me nuts. I simply had to make the radio louder. See what they can do.

 

You have my sympathy @Silverage I hate rattles too.
Is it possible to get some else to drive it while you sit in the back to narrow it down? Rattles have an annoying habit of pretending to come from somewhere different to their actual location due to the internal acoustics.
My other half and I have had several "it's you side", "no, it's your side" type conversations while driving which usually end up in one of us thumping on the dashboard/central console/ door cards.
We have a really annoying one in our ENero which is in the drivers door, intermittant, and only does it when the window is fully closed.

 

I've just called the dealer and they were very sympathetic (and not too surprised). We've arranged for me to take it back a bit later and they'll diagnose it. I'm sure it's not a loose piece of trim as I've literally had everything that will come out, out.

This is the curse of quiet electric cars of course. You notice every sound.

 

Did you have a passenger in the car when you heard the rattle.......

 

I wish

 

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.

 

Don't forget this procedure should be repeated every few months

 

I too suffered from the dreaded rattles just after putting a dozen miles on the clock of this otherwise very civilised car. i took a quick look around the rear end and opened the boot lid. There to find the culprit. I had released the spring loaded luggage screen, loaded the boot with all the gubbins from my trade in buggy and forgotten to secure the screen properly at the end.... Ends clipped securely in place..... Silence reigned!
Just getting used to Far Eastern Technologies and some curious Amber alerts appearing in the dash screen from "Check Front Collision warning' to" Check Lane departure Warning" They all came up and promptly disappeared again! The Car ignored the rather vulgar display as I did when it happened again a while later. Friends in another Forum assure me that this could be an inherent fault to do with a low sun affected the sensitivity of the so called "driver aids" I can expect that in these brand new models which haven't been calibrated to UK weather/ road and Driver use as yet. But as a 12 year lease over 4 cars partnership with Mercedes Benz' E Class' has just ended, I cannot recall one case of a spurious Amber alert being triggered by any extreme weather conditions.

Tesla model 3 - even worse than the Ioniq for these messages. Everything from blind spot warnings, sensor errors, cameras not working, the list went on. Again, it only seemed to affect RHD cars.

 

I had a 90 mile return journey last night and noticed a whole new rattle!

Tracked it down today to the new USB A to lightning cable I'd bought rubbing against the side of the centre console thing. I thought they might have made a pass through hole for cables seeing as there is no wireless Carplay but I can't find one.

 

For anyone still looking for potential rattles, we had one for the last couple months, and finally got the dealer to look at it. The rattle would sometimes go away, and sometimes be much worse than others. As it turns out, gravel from our driveway was somehow getting up on top of the bottom covers. Mechanic was surprised the rocks were getting up there because there was nothing open and/or missing. We drive slowly on the driveway, but the gravel was definitely from there. The sound was all over the right side of the car from front to back.

 

Please show picture indicating where the body covers are.

 

Brilliant find!

 

That’s just were the blocks are that cause the rattling sound as they rub together on mine. Have you got both of your bump stops extended equally?

 

Not at the moment. We are experimenting with various lengths and extended the left block to try to take up the slack, as it were, to get a 'tighter' close and stop the rattle. Unsuccessfully so far.

 

The Chevy Bolt had the same issue. And some got good results by playing with the bumpers. I put felt under the bumpers and it didn't help.
CHECK the sides of the frame to make sure it is not hitting and chipping the paint. It did on my Bolt.
It was never fixed and GM bought back my Bolt last year.
I sure hope that Hyundai is not going to have all the small issues (and a big battery issue) like the Bolt does.
But the Fast charging rate on a L3 might just be worth it to crank the radio and not hear squeeks

 

To fix the boot rattle spray some silicone on the left and right side rubber holders (half way down on each side) and then unscrew those bump stops a little bit.
If you just do the bump stops you will end up unscrewing them so much that the gate is going to be super tight and make a nasty sound when opening, or it will just start doing it again...

Now to find the rattle near the passenger side B pillar that's driving me nuts...

 

Apart from the tailgate (now fixed), I had two other rattles. One was the glove drawer which I’ve applied some silicone to and I have some felt strips on order to go belt and braces on it. My remaining one, like yours, is in the B pillar, but mine is on the driver’s side so it is right by my ear. Actually thinking about I guess your rattle is on the same side as mine - the right side of the car? Passenger side for you but driver’s side for me. I can’t make up my mind whether it is in the seat belt housing or the door/window trim in that area.

 

Yes we have it in the exact same place then, since my car is LHD.

We will have at it with the dealer within a few days.

 

I think it is something in the seat belt housing. Mine sounds like a couple of pieces of trim rubbing against each other. I only get it when I go over imperfections in the road, of which we have many.

 

I'm also starting to think that's where the vibrations come from. They're not super loud, but they seem to come from a spot quite close to my ear. Weird thing is that sometimes I can completely get rid of it by pushing against the door for a quick second while driving. I did see someone post a picture of jamming a folded piece of paper behind the seat belt hanger. I think it was for a rattle next to the back seat (not the twisted seat belt rattles), but it could have been the same issue. Maybe I'll give that a try.

 

The rattle in my car is coming from higher up than the speakers.

 

I don't think mine was the speakers either - it sounds like it comes from the door seal near the seatbelt housing. Its very annoying!

 

This is the curse of the electric car of course. I'm sure I wouldn't have noticed many of these noises in previous ICE cars as they would have been lost amongst the noise of the engine, now as each rattle is eliminated another slightly quieter one becomes noticeable.

 

I had my wife drive today and I think I managed to kill the rattle.
Of course most likely it will come back. My car was completely rattle free for the first 2000km.

Push with some force at these points:

 

We have a really annoying rattle in another car (not I5) which disappears when the window is opened very slightly, do you folks still get the noise if you do this?

 

Had my car in the dealer for paint issues and the B pillar rattle. Again, they lubricated the door seal and hoped for the best. It still rattles 😠

By chance whilst driving Billie Eilish’s “bad guy” started playing on my phone and the rattle went crazy! So I downloaded a tone generator and a 85Hz tone made rattle sound whilst parked.

The rattle in my case was caused by the armrest rattling off of the plastic door card (see attached image). I’ll need to find out how to stop it but at least I now know where it’s coming from. Hopefully others have the same luck.

 

The solution is felt tape, as always.

 

Judging by the fact that my car was rattle free at first and then developed this as time went on, then tightening them is probably in order.
I noticed those screws too, going to go over them tomorrow.... If not unscrew it completely and line it with felt tape.

 

On mine the armrest is doing the most annoying one of the sounds as @JimJam92 pointed out. I'm going to stick some folded paper bits in there and we're going to take apart the doors with the dealer next week.

 

No armrest problems here but I’ve just been out having a closer look at the B pillar / seatbelt / airbag area. There’s plenty of give in all the trim pieces around there so it’s not surprising a few of them are rubbing together. I’m not sure what the answer is to be honest. I don’t really want to get into disassembly or having pieces of paper poked into it.

 

Your car is in warranty so the dealer should be the one disassembling it. The easiest way is to line all rubbing places with felt tape then re-assemble. This stops the issue most of the time.

 

I've got the same. There's probably a sweet spot somewhere with no rattle and the hatch lock not too strained.

 

Did you adjust both equally or did you just do the one side?

 

I did them equally. Asking for trouble otherwise I expect.

 

Update regarding armrests, mine are now fixed, hope it lasts.
They disassembled both doors, fitted felt tape in between the armrest and the door card and re-assembled, zero noises so far. Car sounds like new again.

However, it seems that it might not even be necessary to fully disassemble it to fix this rattle. 1-2 screws is enough to wedge the tape in there. They said it could be done quicker.

 

Any idea how to partially disassemble the door cards/armrest?

I can see the screw beneath the armrest and the one hidden behind a plastic cover near the B pillar when you open the door. The rest of the door seems to be held on with clips But unsure how to undo them.
