Since I bought my Kia E Niro 2020 at 55k milage, it has a rattling noise when I accelerate. I've got an appointment booked with Kia to investigate this. Your sound is a bit different to mine I believe.

 

I've been to three services. In the last one they said that sound of electric motor.... but they can't say whether it is good or bad..... I will probably drive further..... I hope someone will say, don't worry, it's normal
Well, maybe here someone will calm me down or worry me.....
Maybe someone has faced the same situation....

 

Are you by chance talking about the spaceship sound that lets people know the car is moving when under electric only power? If so it should sound all the time not every now and then, when the car is under electric only power. Sorry never mind I just listened to the audio you posted and that's not the noise and it's not normal, sorry.

 

No, it's not that kind of sound. That sound, as you say, is produced by an optional speaker. And this sound is heard up to a certain speed, as far as I noticed, and it's monotonous. And I don't have this speaker. And this sound changes in relation to the engine speed. And what is characteristic, as in the video, it is heard only up to speed 4

 

I remember my 04 and 05 Prius didn't have the spaceship sound because I would have to stop so I wouldn't hit people walking in the parking lot. In the beginning I would just tap the horn as easy as I could to try not to scare people until one lady threw her grocery bag in the air. After that I would just sit and let people walk into the car. Pretty sure my 08 had it so Toyota put it on their hybrids before it was mandated.

 

My (USA) '22 Niro EV makes a sound, but it's not anything like that. It's called VESS - Virtual Engine Sound System, and on mine it diminishes and disappears by 25 mph.

The sound in the video does not seem normal. Sounds like actual gear noise, or something else rubbing. But I'm not any kind of expert.

 

Yes, you're right. This sound if from gear. I have already found the sound sourse.

It is the release bearing, if that's the correct English word for it. There are two. One mechanical, the other hydraulic.... That's how they explained it to me.... I'll know for sure next week.
I can send a photo report if anyone is interested....

It is not so cheep, but fortunately, not needed to change whole gear.

 

Yes please let us know the outcome. Thanks!

 

So. As I told, here is the reason of that sound...

May be somebody knows how it's possible to attach the video. It will convey the sound I heard and clearly show the problem....

The problem turned out to be that there was water in the release bearing and in the gearbox. And everything succumbed to corrosion.... Actually it's strange, because I couldn't see anything like that anywhere else...and drownings are immediately visible....

 

Seams that no way to upload the videos. Here is the short video from YouTube :

You can hear the sound....

 

Basically, replacing the entire clutch kit, oil, oil seals..... everything...

Now my Kia will go quietly quietly....))) the main thing is not to fall asleep in it))

But....its a little bit expensive...but...5-7 years will forget about this....

 

WOW Thanks for letting us know.

 

That hardware was extremely rusty, so I can see how that might have been the cause of the problem. Why so much water got in there is the question, as that area should have been reasonably sealed. Not waterproof, of course. But that really got wet.

 

Guessing that the rust that can be seen isn't the issue. Bad (rusty?) bearing probably is, however.

 

Yes, there's also a bearing inside that made a nasty noise. You can't change it...you have to change the whole set.

There's also two more bearings.

Here's the complete set:

 

Any possibility that your car might have been in a flood?

 

It's likely...

 

And here is the new clutch kit set already in the gearbox:

I was also very lucky that the water didn't get into the electric motor. Because the extent of the damage would have been much greater.

The technicians checked it too, just in case, and said it was fine. There was no water and it was fine...

So...here is the situation
