Squeals and Squeaks
 

I own a 2012 370z and I've had it for about 4 months now. I absolutely love the car and don't have many complaints except for this intermittent squealing coming from my front end. I first noticed this issue when the weather was cold and I would turn the wheel maybe 5-10 degrees to change a lane. Speed also plays a role as it seems I mainly here it above 35 mph. Well yesterday was a beautiful 80 degree day and I decided to go for a drive in the Texas hills. After about an hour of twisting and turning, I started hearing this squeal but much louder. I look a bounding left turn at about 40mph just cruising and the car was making this loud squeak through the entire turn. I also heard the squeal when taking right hand turns. The sound seems localized to whichever way I'm turning. Left - drivers, right - passengers. To add to this issue, my brakes were squeaking when coming to stops (another issue I had during cold weather). I'll be taking the vehicle to the dealer but I would like to know if anyone has ideas as to what this could be. To my knowledge the car is completely stock. Thank you!

No one has an idea of what's going on? :/

Honestly, it could be numerous thing. Your brakes, the ball joints, even the sway bar.

Stick your head under there and see if your boots have torn open or grease is leaking.

It could be many things. You can't diagnose this stuff over the internet. But, when you use the word "squeal" it makes me wonder if it is your power steering belt. Does it make this "squeal " while sitting still and turning the steering wheel all the way to the left or right and hitting the stop?

Wheel bearings maybe.

Branch or stick stuck in the front end? Had this happen to mine. Thought something was really wrong until I found a stick stuck in the suspension.

Stick your nose down there and take a look.

my breaks squeak when backing up on really cold days or if haven't driven for awhile. But once I've been driving around and car has had chance to warm up it stops. Nissan said it's normal and that breaks are squeaky. I'd take it in just to be sure. My car is not a dd so sometimes I go over a week without driving it.

Okay so the problem has been found and (hopefully) solved. I had one of the techs at my work help me lift and look under the car. After removing the wheels we noticed the brakes had quite a bit of rust build up and it turned out being poorly installed brake pads. The previous owner must've installed or had someone install new pads and they never greased the shims. Pretty simple thing to do but they cut the corner. We cleaned and greased the shins and we also used a product called Stop Squeal by BG. So far after 100 or so miles of driving I haven't heard a hint of squeaking. All suspension components are in good shape so it had to be the brakes.

Be sure he greased the slide pin's w/approved grease...as 1 of the 2 have a rubber sleeve over the end's of them...both front/rear.
wrong grease can cause swelling of the sleeve & then seizing of the the slide pin ; resulting of more problems.
