The radio in my 2012 Silverado emits a loud, annoying and constant high pitched noise, even when shut off. Apparently, GM acknowledged the issue and said it was due to a cooling fan in the radio. They outlined this in PIT5166A and PIT5166B. However, they said the issue was normal and to not replace the radio, and that GM was working on a fix. I read on another forum that GM came out with a revised notice, PIT5166C, but I can't find reference to it anywhere. I was wondering if anyone has access to PIT5166C and if so, does it authorize a repair or radio replacement? I know I could probably call the dealer, I just want to do a little research to see if its worth my time to take the truck in. Thanks

I'll have to check mine. Is it the nav or Bose or six disc?

 

It is not nav or bose, just regular CD. Start your truck, turn the volume down, if you have it you'll hear it. It's a distinctive buzz/hum from the radio deck.

I just took ownership of a new 2013 Sierra SLE about two weeks ago......it has the standard factory radio/speakers.

 

I too have noticed the high pitch noise....which led me to google....and that led me to this topic/forum.

 

Is it safe to say there is a definate fix via replacing the radio? I have yet to call my dealer but want to have my research done before I do.

 

Any further insights would be appreciated. Thx, John

I just dropped my 2012 GMC SIerra off this am for this & a couple other concerns. My truck has the "UUI" radio head unit. I'll let you guys know how it turns out...

I picked up my 2012 Sierra yesterday evening. That annoying buzz noise is gone, the new replacement radio head cured it. :thumbs:

Does this apply to the Bose system too? My '12 Sierra does it, but it seems to vary in pitch with the throttle, or get higher pitch as engine rpm increases. Maybe not the same issue but definitely a noticeable whine.

Not sure what you mean "radio head"?

The radio itself, sometimes called a head unit.

      Mangoal or FitcamX OEM Dashcam?

      By MANGOAL · Posted

      Late reply, but yes—it works on the SLT trim. Compatibility comes down to the plastic shroud shape behind your mirror, not the trim badge itself. On the SLT with auto-dimming, it uses a plug-and-play Y-harness off the mirror/rain sensor power, so no need to run wires down to the OBD port. If anyone's ever unsure about fitment, just drop a photo of your mirror housing and we can double-check it.   Appreciate the detailed feedback on the install! On the windshield glare—we actually took feedback like yours and developed a dedicated CPL (polarizer) filter to cut down dash reflections on sunny days. If you're still running the cam, shoot me a DM. I'd be happy to send a CPL filter over for you to test out—no charge.

      Yes, every time the developer updates his code, you must recompile. I will private message you with the latest because it changes pretty much with every version.

      Transmission Temperature Hitting 220s

      By Grumpy Bear · Posted

      After I wrote that reply I went for a ride. 85 F out. So trans started at 85 F and it shifted the same as it did an hour latter at 168 F. I've never actually recorded the to cold to shift point but it is under 32 F before they start hanging on to a lower gear or leaving the converter unlocked. Both intended to heat fluid.    Yes, brake or bake. Absolutely.      Your welcome. True research ended decades ago. Field trials are still in play.    There is a thing called oxidation onset temperature. This is the heat related oxidation not the O2 exposure kind. For mineral oil that starts at 140 F. So what happens after 140 F? Each 20 F cuts fluid life in half! Does using a Full Synthetic improve that? Yes! By how much? Depends on the base oil type and a few other factors. But enough to notice. Some esters are even higher. There are even synergies between types the will raise it higher than any one component is alone.    Then there is "Hindered" oils. Antioxidant additives. Hindered Polyol Esters can sit at 500 F for years in a turbine.   When a blender brags his oil will 'take 500 F" in service he doesn't specify for how long. Water will dance on a 500 F hot plate for several seconds. @newdude put up a chart showing the relationship between fluid temperature and it's life in an automatic transmission. Here's a version of that chart for Group III based oils. These temperatures are those in the pan as observed as 'normal'. that is you drive as you do for as long as you do under what load you ask of it and whatever that temperature is this graph applies to. Flash temperatures of a few minutes isn't what his means.    Note that fluids held at a constant 240 F have a service life of only 20K miles. 220 F explains the factory exchange limit, eh? My equipment I keep under 180 F and I'm good if the cooler will hold it as low as 140 F. But that's me.
