Hello,

I have a G37x 2012 and the front wheel passenger side makes a squeaking. The video shows the sound. Could you please help me with this? Is this a serious problem or not?

It's not always like this. After some driving it starts this sound.

Thanks!

Ehh I'm not going to download your file. Host it on youtube, google drive, etc. So here's my guess without viewing;

If it starts after driving than it's likely related to a part heating up, expanding, causing it to rub on something. I had this exact problem over the winter on my rear wheel, and it ended up being a prematurely worn brake pad. Basically the caliper bolt had seized, causing the inside of one pad to wear down much faster than it should have. Super easy fix and just cost the price of new pads and caliper grease I already had.

Rotors might be slightly warped/worn. I usually sand mine down each brake job to resurface them (unless they actually need replaced). That might be a viable option if that's your issue.

It could also be a wheel bearing. Look up some youtube videos on how to diagnose a wheel bearing failure. It's a pretty straight forward process.

I'd start at your brakes and rotors though. Pull off your wheel and actually inspect them. With my issue last winter, I just looked through the wheel and couldn't see the rear pad had extra wear on one end, because the rest looked normal.
