Rear rattle knocking noises fix

Ok people. Heard another knock, knock, knock. Buy not on the actual road. I like fishing and fossicking here in Australia so go on some dirt roads now and then to do so. Nothing bad that any normal car could not go on. But on the dirt ones I started to hear it. It sounded more hollow than the first which was from the 40 split rear seat section, more like an outside the car knock. But, when I dropped the 60 section of the rear seat it stopped. Crazy, sounded like an outside knock but was the other side of the split rear seats. Some more leather tape and its silent.
I read elsewhere that Lukosilk which is a fabric type that is available in almost every Chemist (Here in OZ are Chemists, in US called Drug Stores) is also great as a sound deadener for this issue and used.
So dont be fooled if you hear a knock and think its external! First port of call drop each seat and listen. Also try the rear hatch and rear passenger doors I hear too.
Hope this stops some future hair pull out issues.
Cheers all.

Jon - finally tracking this down. Could you listen to this 30 second audio clip - it appears to be from the left rear seat but only when it's in the upright position - if it's reclined back, or folded all the way down I dont' hear it. I have tried some Gorilla Tape already per your suggestion - I'll let the service guys take a look later this week when it goes in for 2 recalls...

Hi. Yeah that'd drive me mad. Was how mine both sides sounded. Stopped one then a week or so later the other started. The other side took a bit more tape to shut it up. Ran out of that leather look stuff so just did several wraps of insulation tape.
Now and then when im going fishing and on a dirt track, going down hill, never up, I hear a little vibration type tickety tick from the seat catch area. Nothing like the knock and I can live with it as it only happens in that situation, but im convinced that this one is from the catch mechanism itself, spring or whatever part of it. Iv had a look but cant figure it out. If When its all in place and I knock the back of the seat a few quick times with my hand I can hear it, but cant tell excatly which part is doing it. I can live with that one if it stays that way but that constant knock everywhere I drove no way. Have you had someone sit in that seat whilst you drive to see if it stops, or sit in the back on the opposite side?
Stupid question as you probably have.
2 recalls, that seriously sucks. All I seem to hear and read about these days is recalls on cars from all manufacturers. Fire risks, brake issues, power steering faults, transmissions, air bags killing people.... doesn't say much for modern car manufacturing does it.
Good luck getting it all sorted.

Thanks - I do have a neighbor who is great all around renaissance man and he helped me with the Santa Fe that I traded in for the Seltos. One of the two problems in that car was under one of the rear seats. The seat cushion was hitting on the metal spring under the seat and making a twanging sound. that was South by just inserting some weather stripping between the cushion bottom and the spring.

I wanted to look under the seltos rear seats but you cannot get under the rear seats in that car. I took everything including the storage cover out of the car and yesterday was having a hard time recreating the noise. It is so frustrating. The dealers are generally not much help with these situations. And you're right, Kia needs to get their act together about the engine fires etc. they are as bad or worse than other manufacturers at this point.

well at least it gives me something to do in my old age here. thanks for responding.

Hey, since we share a mutual intense frustration at unnecessary noises in the car, here is a 38 second video on YouTube that I uploaded with that 2020 Santa Fe that I mentioned. This problem was a clicking noise from the center dashboard, especially in cool and colder weather. The dealer could never fix it and I sold the car like that. in this video we had taken out the row of buttons for the heated seats you can see the wire hanging down. we were thinking that part was the culprit. But the clicking continued even with that part removed! Talk about frustrating.

Just listened to it. I utterly hate knock and rattle sounds. I get it in old cars, get it by saying ok they are old, but new ones I hate with a passion. I had before the Seltos a Nissan X Trail, think they were called Rogue in the US. I had a knock sound in the rear I could never find. Was nuts in our Summer but quiet in our Winter. Had the X Trail for 6 yrs. In Summer I played the music loud to drown it out, was all I could do. Also had click now and then sounds from the Dash.
To be honest if I had to choose right now, id choose my Seltos sounds. The X Trail had me nearly on Valium it was that annoying.
Oh for the days of older cars. Had here in Oz a Holden Panel Van that never made a single noise, then a Ford XE that was brilliant. But after steeping into these modern cars....its hair pulling stuff noise and recall wise. Yeah tech wise we may have gone forward but overall quality.....its a joke.
Again, I really hope you find the issue. Mine is now the Transmission not engaging several times a month and about the same number of times the Cruise not doing so.
Modern cars...pffftttt. I say. Good luck mate.

Simple fix. Great work.Thank you. What a shame that we as customers need to do this for satisfaction and to help KIA MOTORS out. W o W!

Your welcome and yes I agree. We shouldn't be buying cars that rattle like these do when they are new. Fair enough an older car but not new.
Out of interest please, the front part of the bonnet/hood area that has the Kia logo, on yours if you look at it from different angles do you have ripples on either side of the KIA logo? Mine does as do many others here in Australia. Mine has 4 each side and I saw one the other day with 3 each side. Iv seen numerous others with them. Im in a discussion id put it with KIA here that its a manufacturing defect, one said no its supposed to be like that! Yeah sure, then how come some have 8 ripples and others 6! On many angles you dont see them but on others like in my picture you do.
Here's a picture of mine.

Hi - new member. I've had my 21 Seltos since last June. I too started noticing the rattling/banging noise from the back area myself. It happens on any road condition and under any speed. I took it in to the dealer and when I got back, I was told it was the winter tires I had on the vehicle. I snickered and said that, no, it was not a tire/road noise. The service manager came out and agreed to go for a ride with me. Of course the noise never appeared - at first - but when it did, the service manager said it was inherent with this model of Kia. He indicated that he drives the same model and has the same noise. WTF? You know of the issue and you won't fix it? Nope, not until it is recognized by Kia and they come out with a fix. WTF?? Obviously Kia knows about it.
It is such an aggravating nuisance and I can only turn the stereo up so loud before my wife complains. There is no way this should be a problem on a new car. A few years on our hometown potholes they call roads, yeah, but not a new vehicle. I will try a couple of the McGyver fixes but really, should we have to?
