It Happened Again! Loud "feedback" type sound. - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

chipset35 · 11-01-2013, 09:24 AM

On my 2014 2SS 1LE, for the 2nd time in 5 weeks, I was stopped at a light and all of a sudden I hear this loud "feed back" type sound like when you hold a microphone to close to a speaker.
A high to medium tone that starts lower in volume then picks up and then at its peak, which is loud, I usually do something and it stops.
The last time this happened, I do not recall what I did to make it stop, but this time no windshield wipers were being used, I did not flash my high beams like last time or have my defogger/defroster on.
I had the A/C off, and radio off, with my window opened about 2 inches.
I was in neutral, and about the only thing that changed was I pressed the clutch in and shifted to accelerate as the light turned green.
I "think" I adjusted my radios volume control, or turned it on or off, I do not recall.
Is it possible this is some kind of feedback from the stereo speakers or maybe onstar?
I did use my cell phone earlier via the cars LCD panel.
I wonder if this is some sort of speaker malfunction?
I need to watch more closely next time.

Seeing the you have a 2014 I'm guessing you don't have a after market radio?

If it's stock I would take it back to the dealer!

Sounds like it might be a speaker issue. Does it emanate from one side of the car and the last time this occurred, were your windows closed and still sounded the same?

AdamEL · 11-01-2013, 10:58 PM

Maybe it's your trunk monkey hooking up the karaoke machine?

Wow! You too?
I am going to keep a closer look and document what I do to remedy.

Sounds like a grounding issue

KaBoom1701 · 11-02-2013, 12:07 PM

Got any audio clips we can hear?

Might help us figure this out.

It's the people driving by groaning at the new rear lights ... sorry, couldn't resist.

chipset35 · 11-03-2013, 07:49 AM

I love those new rear lights, looks retro instead of like a corvette.
I sure hope it is not the driveshaft rubbing somewhere, as my Volvo S60R made a similar sound, and the only difference is that the S60R made this sound while moving and the Camaro only makes the sound while at a stop.
It sounds like a medium to high pitch woodwind instrument.

Blownhotrodder · 11-03-2013, 09:15 AM

Its either the audio system or maybe sounds like something under high pressure releasing like maybe the a/c system. I think its the audio system.

chipset35 · 11-03-2013, 03:59 PM

Odd thing is both the A/C and Radio were off.
I think I recall trying the volume knob just for yucks.
All I know is it stopped when I started moving.
I am worried about this big time.
