2012 Kia Optima Ex Turbo 2.0
Engine was replaced by KIA in October.

Need help?! I've recently noticed I get a type of rattling noise when around 2500 rpm right before a gear change. It sounds loudest in 4th gear. Is something loose? Or could it be transmission? Noise is coming from driver side. It almost feels like it's close to the dash but definitely something under the hood!

I can't tell for sure which sound you are referring to.

Can you identify at what seconds in the video the rattling is louder, and quieter?

I hear a kind of buzzing sound, like someone's phone on vibrate, is that the sound?

Yes it's starts at around 14 seconds when I rev to about 2500 rpm. It sounds like buzzing in the video but more like a rattling. It makes this sound when I accelerate normally but won't at higher acceleration.

Ok I hear it in the video clip--does it make the noise right around that RPM range even when gear is in neutral and/or regardless of what gear your in?

Check the voltage on your (EWG) electric waste gate…

When it’s off, I’ve heard of this happening and had a similar issue on my Optima.
