High rpm buzzing noise - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Frsultramarine15 · 11-11-2014, 11:07 PM

I've been noticing this buzzing sound in the high rpm ranges I think it's the windshield but not sure anyone else ?
And completely off topic how good does a car seat fit lol

No buzzing that I notice...but I do hear a harmonic type hum around 70mph

Oh maybe it's just me being Paranoid because I went out for another drive and I didn't hear it once

Is the hum a little high pitched? And is very apparent only at 70 mph?

No...my passenger could hear it too. Also other people have reported hearing it in this forum. It doesn't appear to be related to RPM...just MPH.

I wouldn't say high pitched...more medium pitched. It starts to kick in about 68mph, is most apparent at 70mph, then starts to fade again above 70mph.

Have you done the sound tube plug/delete?
Or...
Very, very little soundproofing so you hear things you would not in a "normal" car. Engine, tires, body panels in the wind all can make some weird noises that just stand out more.

cpafford · 11-12-2014, 09:28 AM

Cant say I've had any humming when at those speeds but its possible this car doesn't have the best sound proofing so you get all kinds of interesting sounds you wont hear in other cars these days. For your off topic question this car is not very car seat friendly but it works i have 2 in mine one is an infant and the other is for my 3 year old with the infant on the passenger side. my wife refuses to use my car as the family car cause she feels cramped but that's cause she doesn't adjust the seat right.

There is a recall for a buzzing shifter on manual transmission cars, it could be that.

There is a service bulletin (not a recall) for the rattle but it only applies to 2013 models and the dealer will not likely do it on a 15.

Yeah that happens in my car as well? Are you MT? and does anyone know what that sound is?

daiheadjai · 11-12-2014, 09:32 PM

Does the hum occur when you turn? My wheel bearing took damage and ended up with a hum and vibration when turning or at certain speeds

Guys!
Again.
Have you plugged or deleted the sound tube???? It gives you some very strange noises.
If you don't believe that then it could be belt hum, flywheel chatter, tire resonance, anyone of several pumps, air intake, etc. etc.etc.
You are sitting with an engine almost on your lap, a transmission against your butt and a drive train that extends the whole length of the car.
You are separated from all this by steel two thicknesses above tin foil and some felt with delusions of being carpeting.
You will hear weird noises!

Car is completely stock. The hum to me sounds like it is coming from the rear of the car. To me it sounds like a hum generated by vibration due to wind. I'm thinking maybe from the rear bumper.

Are three posters in this thread the same person?
