Rattles/Squeaks in the BRZ?

Every tank from brand new has been filled with 92 octane Chevron, 10% ethanol IIRC, from the same filling station near my house.

Interesting, you are the 1st person I've seen/heard with decent amount of miles that does not have the chrip that uses 10% ethanol gas.

I should note that my claim of no chirping is made with me having only monitored the engine noises from the cabin, not with the hood open while the engine is running. I've actually wondered if I do have the noise, and I just haven't been able to hear it, or have heard it and wasn't bothered by it. I have no plans to open the hood and test that condition, I'd rather stay ignorant in this case I think. That is unless I begin hearing that the chirping noise is prelude to some larger mechanical issue.

After hearing people complain about specific transmission/drivetrain noises, I realized that I had heard some of the same types of (muted) sounds coming from my car, but I interpreted them as normal mechanical noises, not sounds to be bothered by and worried about. Perhaps it's an issue of perception.

The chirp will get louder to where you can hear it at a stop light. But with the amount of miles you have you should have gotten to that point. Do you drive your car easy? Meaning under 4K rpm and do not redline the car?

I generally drive fairly easy, meaning that I don't run the car much over 4K while in town, but usually twice or so a day there is an opportunity to gun it where I'm getting on a highway, and in that case I run the engine up to 6-7K in a couple gears.

Well, keep us posted if you hear anything.

Seems to me that most of the vibrations are causing from normal road vibrations, and not so much from the engine. At least in my case 99% of the rattles are coming from the rear.

Mine seems to have lots of vibration from the engine/transmission area in higher rpms. Not sure if it's got something to do with the 10% ethanol gas or just how the FA engine is at high rpms.

I made a thread for the clicking/ticking noise coming from the rear, which actually is from the rear deck.

Note: This is not the 3rd brake light housing rattling noise.

I'm in the Bay Area, so I do have ethanol I believe. I just haven't heard anything other than the occasional speaker rattle when I crank the tunes. I'm closing in on 3k miles, and I followed 1k mile break in, but after that I have taken it up to redline numerous times.

People who don't hear any weird noises could be just because they have their stereo on? Maybe you'll start hearing noises when you drive with no music. I hardly have my musics on when I drive.

Stereo off the majority of the time. I've seen the idle issue, I've had issues with Bluetooth in the stereo, but I've had no odd noises or rattles or anything. It's possible they're happening during the short times I have the radio on, but I might just be lucky.

I see. You're the lucky one.
On a good time, my noise free ride is about 5 minutes.
I don't really mind the rattles. Most of the cars have some type of those noises. I just can't stand the ticking/clicking noise from the rear.

You are a freaking genius! I shut the A/C off during my ride home and it was quiet as can be. As soon as I turned the A/C on it kept making the squeak noise.

Now I just have to go to the dealer and see if they can fix it as it can get awfully hot in the northeast in the summer.

Thanks again!!
