FIXING the Infamous Kia EV6 Rattle! 😀

My 2022 Kia EV6 has had a rattle tapping sound for as long as I can remember and it's so annoying. I tried everything I could think of to find the rattle in my Kia EV6 and fix the issue, but nothing worked. My local Kia dealership unfortunately was no help either. Well Jon - AKA @unobtaniumsquickreviews6999 - has been working with his Kia dealership to figure out what the issue is and they found these cabin pressure flaps in the back that appeared to be the cause. Sure enough, that was it. I put some yarn in between the flaps and the contact points in my Kia EV6 and no more tapping sound! I'm so excited. I hope this helps you guys out too 😀

I'm SO excited to finally have an answer here. Hope this helps you guys too! Thanks for watching! Be sure to SUBSCRIBE for more videos 😀

[@EV-olution]

I have also noticed the sound, but I would suggest not leaving the vents open and not using yarn since water and time will probably cause them to get moldy, maybe. I would suggest thin automotive foam tape around the flap edges to allow them to function as they do, but would stop the sound of the flapping.

[@TechnicallyJeff]

Yeah the yarn was more of a temporary fix while I had it open. That said, I don't think moisture can really get there much and the EV6 does have the auto dehumidify feature. I don't think it'd be too bad. But yeah foam tape would be better.

[@franklyfrank123]

Yarn is a good solution actually, because you don’t need to worry about it falling off.

[@TechnicallyJeff]

I was thinking that. It also was the only thing I had on hand lol

[@markc19821]

[@caktusmatt]

Thanks for this, I had mine apart last weekend looking for the noise, but didn't find it. It really makes sense that I never heard it when it was wet or snowy outside, perhaps a slight bit of moisture keeps mine from making that noise, but for sure on dry days I have it at highway speeds.

[@TechnicallyJeff]

Yep same here. That's what I was thinking. I'm glad it's helpful!

[@errorjuster]

Thanks for sharing! I've noticed that rattling sound while driving on the freeway, and it drives me nutz! Especially since my wife doesn't notice it at all. I wonder if a thin foam filter would dampen the sound and still vent air pressure.... might have to tinker with it on the weekend 🤔

[@TechnicallyJeff]

Yep that would probably work!

[@soaringsam5]

Thanks for sharing this eureka moment! I was bothered by this tapping/flapping noise since I took delivery of my GT-line over a year ago. Tried many adjustiments without success. Now that you've shown me the cause, my worry is resolved. I won't even have to go through the trouble of digging them out. No worries now, mate!

[@dougcronkhite2113]

Yes! I've had my EV6 for 2 days and it's been driving me nuts! I'm going to design and print a TPU ring for the vents to stop the tapping but still allow them to close and operate normally.

Awesome! Sounds like a great fix. Good luck!

[@rogerstarkey5390]

You could run a thin bead of hot glue around the contact face of the flaps, keep them open and let it cool. That would leave a softer contact patch. If you think it would affect the weight / operation of the flap, put the bead on the face of the panel.

[@TechnicallyJeff]

I thought about that but didn't have hot glue. Thinking about it more though, hot glue is somewhat hard. Even if it's a little softer, it still would make a sound with the flap closing. And the fact of the panel is hard to do I think. Several spots it contacts have a VERY thin cross section.

[@TyTyMcGinty]

You're the proud owner of the only EV 6 AWD Wind with the Yarn Baffle package lol.

[@TechnicallyJeff]

Haha yep!

[@murattekic4983]

Thanks for video

[@TechnicallyJeff]

Happy to help!

[@winstonian88]

Weather stripping along the flaps might work better? Or even a bead of silicone? That way they can still operate, won’t be affected by water, but will be cushioned?

[@TechnicallyJeff]

Yeah someone mentioned weather stripping. That could maybe work. The challenge is the points where they touch are often VERY thin plastic.

[@grimmrlg]

If you simply purchased some thin 1/16" foam with adhesive backing, it could have been cut to fit the flapper. What you did likely leaves air flow through the vents, you could have just glued them shut or open.

[@TechnicallyJeff]

Yep that would probably work well.

[@Katy-o2j]

Good morning Jeff, the noise has been so annoying, we had the boot (trunk) cover out, the tool kit wrapped up and still couldn’t fix it. Just shared the link with my hubbie to get him to fix it later today. Will probably use some thin adhesive pipe insulation foam, should do the job.

[@TechnicallyJeff]

Yes it's very annoying. My new GT makes the sound and I'm debating what to do to get it to stop.

[@michaeltaylor3332]

Good to know. I had never noticed the tapping, although it could be present. I usually play my music loud, so I wouldn't hear it anyway.

[@TechnicallyJeff]

Haha yeah it's faint so if you have music playing it'd be hard to hear it.

[@Takusman]

I am sooooo glad my my22 gt-line AWD does not have that problem, maybe a bad batch of those flaps? Also I noticed the flaps are vertical and if you live in SoFL you see cars without the rear bumper all the time and those flaps are sideways, seems like bad design or bad batch.

[@TechnicallyJeff]

Maybe? Idk it seems pretty across the board. Even new GTs and Winds have the problem. Might be hard to hear depending on the car and if you listen to music all the time.

[@Takusman]

@@TechnicallyJeff i can confirm as of right now, i do not get that issue, driving with no music, 0 noise

[@TechnicallyJeff]

That's great!

[@nomation]

Hey Jeff, have you heard the tapping in your new GT? I have not as of yet but thought I would ask.

[@TechnicallyJeff]

I have a little bit but not a lot

[@pookie3093]

I’ve had my Limited Edition EV6 for a month now, but have not yet noticed the sound. But I think I’ll address it when I try and put the sequential rear turn signals in before springtime. I am wondering if those flaps were made that way for airflow or something. I don’t want to prevent or block air if that was Kia’s intention, but I do want to get rid of the sound that may or may not be there. I was thinking of some kind of small adhesive rubber or silicone studs or something just to stop the flaps from smacking the base, causing that flippin sound. Guess we will see…

[@TechnicallyJeff]

Good luck with it. Yeah they are there to vent air pressure in the cabin. I know a few people have improved it a few different ways.

[@franklyfrank123]

Could you make a video on how to remove the pieces in trunk and reach the vent area? I checked my car today and couldn’t figure out a way to tear it apart 😂

[@TechnicallyJeff]

Did you get the panels on the side out? Once they are out you should be able to reach the flaps. It's hard to record unfortunately in that area.

[@createdeccentricities6620]

Congrats, Jeff! Let me tell you about the annoying rattling sound that appears to come from the dashboard of my '22 EV6. I can't say when it started - we've had the car for 1.5 years and really like it - but now it seems to be audible when the car's driven on anything but the smoothest road surfaces. I have taken everything out of the glove compartment and front cup holders, and I have looked over the frunk, but nothing seems loose - and the noise still occurs. So, I suspect something's loose under the dashboard panels but I don't know how to remove them. Also, it may not be a good idea for me to attempt it. Then, too, I imagine the dealer would charge a hefty sum to do the R&R. Help!

[@TechnicallyJeff]

Hmm I (and others) have heard a rattle under the center console, seemingly under the wireless charger. Is that possibly the area? If I push on it the sound goes away. I just haven't taken the time to really look into it. Otherwise, I'm not sure what it would be. As for the dealership, you could bring it in and say there is a rattle behind the dash and you're worried something might be loose that could cause an issue (electrical, etc). I know my dealership would drive it, listen for it, and try to figure it out.

[@labaom]

I have this weird squeak/rattle coming from what seems to be the front passenger area. I tried the obvious stuff. The only thing I can pinpoint is that the noise is only present during cooler parts of the day. When it is warmer out there is no noise. It must be some sort of plastic piece that is expanding and contracting. Any thoughts?

[@TechnicallyJeff]

Hmm do you have mud guards? All trim pieces nice and tight?

[@garyying2413]

Thanks for sharing. 👍🏼 On the other hand, the said method may defect the purpose and function of "quarter panel vent". As the flaps are permanently open, dust or insect can enter the cabin. Besides, the openings are partially blocked by the wrapped material. Counter proposal: use thin insulated film to wrap the frame opposite against the inner surface of the flaps. This won't affect the movement of the flaps due to additional weight bearing on them.

[@TechnicallyJeff]

Yeah I don't think too much will get there but we'll see if I notice anything. Might just change the cabin air filter more often lol. But yeah I was thinking it could make sense to glue a little weight on the back side of the flaps. That would make it a little harder to open and keep them from fluttering all the time, but still would work for the major pressure.

[@garyying2413]

@@TechnicallyJeff perhaps, you may design or modify the vent and sell to KIA or customers directly. Btw, KIA should issue TSB on this matter. ☺️

[@TechnicallyJeff]

Haha that would be cool. I need to look into that.

that'd be nice

[@MrDarni78]

Wont this yarn get wet when raining or washing the car? Have you seen if you get a leak inside?

[@TechnicallyJeff]

I don't think so. It's inside an area that seems fully enclosed for the most part. I'm not too worried. I'll keep an eye on it though.

[@Polanco2030]

Im around 1500 miles on GT-Line, sound hasnt come out yet, will speed tape works ?

[@TechnicallyJeff]

Maybe you won't have the issue. Idk about speed tape

[@vegawan4765]

I have never experienced it, to be perfectly honest. However, it's best to learn, in case it happens in the future.

[@TechnicallyJeff]

Yeah that's good you haven't experienced it

[@Nexinator]

I don't think that forcing the vents open permanently is actually going to be a bad thing. In normal ICE cars, which ventilate only when the car is active, sure, I can see why this would be a thing. Don't want to ingress moisture after a downpour. But the EV6, from what I've read, does a ventliate funciton now and then to dehumidify the car, so it naturally will vent the car while parked. Doing it this way though, not sure it's the best way to do it, I'd have, as you said, put felt tape on the flappers and quietened it down that way.

[@TechnicallyJeff]

Yep those were my thoughts too.

[@beidlern]

I'm sure other vents will compensate for the dif

[@TechnicallyJeff]

The vents are kept open some with what I used so there shouldn't be any issues with airflow.

[@evodessey]

That’s a great find. Now if only someone could figure out where my Active Sound Design Menu option disappeared to after my Meridian Amp swap…

[@TechnicallyJeff]

Whaaat? That's weird. I did recently learn some markets don't have the active sound design option. Did anything get updated in your software too?

[@evodessey]

@@TechnicallyJeff No they just swapped the Amp. Other bits of Meridian menu remain and also the surround modes but Active Sound Design is not in the menus or even searchable in the settings.

[@franklyfrank123]

@@TechnicallyJeff Thank you Jeff! Today I listened to it carefully and found the rattling in the video in my car. It sounds exactly like what you showed in the video. I also did more research on the squeak from my door, and I think it could be related to my recent ceramic coating job. The fix I’m trying to apply is to clean the rubber seal, and put 3m 5430 tapes to the contact areas.

[@TechnicallyJeff]

Yep it can be quiet, but with the design it should be in basically every vehicle. Hopefully you can et rid of it!

[@jaredfinklestein4050]

I have the same rattle coming from my driver door - or it could be just under the car in the same area - not sure. I already tried to get the dealer to fix it, but they didn't on the first go around.

[@JhdsonsHgf]

Are there front cabin pressure vents because I removed my rear ones and still have a similar loud rattle from the front.

[@TechnicallyJeff]

Not that I'm aware of, but there could be I suppose. Where do you hear the sound? Any particular side?

@@TechnicallyJeff I hear the sound from the front left and right side simultaneously. I removed the rear ones and it got rid of the rear rattling.

Could this also be in the right front of the car? I have a similar sound coming from somewhere in the dashboard. It is driving me insane.. Also only apears when I drive around 80/100 kmh. (that's 40/60 mhs?)

[@TechnicallyJeff]

Hmm I don't think so. I haven't heard anything in that area and I don't think they place flaps in the front. They are designed to release air when the HVAC is not on recirculate, and that air comes out the front and exits the rear. It could be something loose. Maybe check the panels on that side.

[@rafaelcanizares9195]

Hello, I have exactly the same problem. I hear a rattle noise coming frome the front. Somewhere behind the central screen. And it seems to be related to the speed, not to bumps in the road. I have removed the cover of the central speaker at the front but couldn't find the source.

[@TechnicallyJeff]

@rafaelcanizares9195 does it make the sound with the air on and off with recirculate on and off? Sometimes the climate control system can make some noise with the fans.

[@rafaelcanizares9195]

Thanks for showing interest. The noise doesn't change if I switch the AC on an off, if I change the fan speed or if I modify the air recirculation. It is not very loud, but once I started hearing it I can't stop.

[@TechnicallyJeff]

Hmm anything in the glovebox moving around potentially? Or in the frunk?

[@DanRoBurton]

Some manufacturers actually have those flaps made out of rubber instead of plastic. That would resolve the issue.

[@TechnicallyJeff]

It is actually a rubber material, but it's hard so when they come down on the hard plastic, it makes the noise.

[@El-ng7mb]

Huh i never heard that yet thankfully

[@TechnicallyJeff]

That's good! It's usually more apparent when it's dry and you're driving at high speeds with windows up and no radio playing.

[@ev6-joerg]

Is it possible that this problem does not exist in the GT-Line version? I drive this EV6 version since november 2021 and I never heard this type of noise 🤔

[@TechnicallyJeff]

They all have the same design so it should be the same. You may not hear it unless at high speeds though. And some are louder than others it seems. And if you listen to music it's harder to hear it.

[@ev6-joerg]

@@TechnicallyJeff I had some drives with interested friends who were thinking about buying such a car and we were driving without radio on and it was absolutely quiet in the car at all speeds. All my friends were very excited about the silence while driving. So, I'm wondering that your described problem seems to exist in some cars.

???Doesn't that defeat the purpose of the vent by blocking the air flow with yarn???? What is the purpose of those vents?? Felt pads make more sense as long as they do NOT block the air flow..

[@TechnicallyJeff]

It doesn't block airflow. They can still open further and air goes around the yarn. If anything it keeps the vents open instead of allowing to close, so it's not quite such a sealed cabin. The vents allow air to escape if cabin pressure builds, like when not using recirculate or when you close doors.

[@joejones6968]

I would highly recommend that you do not do what you just did. You tell the dealership that they need to add resolve to this. You explain how you are the customer, and they are the service provider, and that this is going to be addressed just like you said it will be. Period. End of negotiation. I can 100% promise if you drop a note to Kia of America if your dealership causes you any distress, and are incompetent in resolution of this matter, after making several attempts, you will absolutely get what you came for 100% of the time every time, all the time. Please remove all that you did as fine dust and possible dampness caused by the cotton/wool combination in the yarn, and high voltage is a recipe for catastrophic results. You must insist your dealership address this issue and add resolve to your liking, not theirs. You are the customer. They do what you request or otherwise expect them to do until a resolution is reached. Period.

[@TechnicallyJeff]

I get where you are coming from, but this is unfortunately not something the dealership will resolve. Many have tried with dealerships and the problem is the air flaps are acting as designed. They open and close when needed to vent the air and balance pressure. The sound is an unfortunate byproduct. As for my solution, all the battery components and wiring are sealed and even on very damp days it doesn't get damp. I'm not really worried there too much.
