High pitched noise

[imfletcher]

Hope you guys can help me… I just traded my 2007 Tahoe for a gently-used (20k miles) 2013 Tahoe LT at Carmax. The new truck is great except for one issue:

I can hear a *very* high-pitched ringing noise from somewhere around the radio. It's very similar to the sound you'd hear from an old CRT TV if the volume was turned all the way down. Or, if you've ever experienced tinnitus ("ringing in the ears"), it sounds like that.

You might be wondering if the problem is with my ears, not the truck. I wondered that too, so I did an experiment -- I put my dog in the truck. She freaked and jumped out. Successful test, as far as I'm concerned.

I hear the sound when the radio is off or on. It doesn't change with acceleration. The weirdest part - I hear it *before* I start the engine. When I shut the engine off, I continue hearing it for a minute or two, then it stops.

It's not the same whine you sometimes hear when you plug an external device in a car radio's aux jack (I've had that problem in other vehicles). That usually changes with engine RPM, and only when the radio is on. My sound is quieter and higher pitched.

I have the factory radio, without Nav. No aftermarket accessories. It's 100% stock.

Has anybody ever encountered this before?

I pulled the fuse for the radio. No noise. Put the fuse back. The sound came back.

It's got to be wired to ignition whatever it is. Just start unplugging each item one by one. Could possibly be the radio. I have tinnitus so I know how you feel.

Hello imfletcher,

Congratulations on the purchase of the new-to-you Tahoe! I can definitely understand how it can be frustrating to hear a high pitch noise coming from around the radio area in your Tahoe. As a customer service representative, I'm not able to provide much in the way of do-it-yourself information, so I'm glad to see forum members are beginning to step in with feedback. If you have any lingering concerns, please private message me.

Does it have a rear DVD?

I have the same issue. Its like a white noise coming from the speakers. Sort of like when your AUX wire is plugged in and I unplug my phone to answer it. Yeah its annoying, i usually drive with music on...

My 2007 Tahoe never did that, but my 2012 does....

No rear DVD.

Interesting that two of us have this problem in our '12/'13s, but we didn't in our '07s.

Just traded in my 2007 Tahoe for a 2012 Tahoe. I also have the very high pitched noise coming from the CD player area. I have discovered if you lower the interior dash lights, the noise gets much lower and almost goes away. However, at dusk when the interior dash lights automatcially get brighter the noise comes back.
I have been reaading that others have had the radio changed out to a Panasonic.
I have spoke to my service guy at Chevy dealership, he has not heard of this issue.
It is very annoying and I beleive the dealership that I bought the vehicle from knew of this issue possibly from previous owner as the interior light dimmer button was turned all the way down to the lowest setting.
Not sure if i should pursue having the radio changed or if it is an issue with the wiring of all the lights in the dash.

HELP!?!?

Did you ever get this issue fixed because I'm going through the same thing in my Tahoe now?
