What Is This Ringing?

Does anyone know what this ringing noise might be or has experienced it themselves?

 

What you are listening to in the sound clip below is the truck cruising at 40mph and going over some bumps. I lightly press the accelerator pedal around the 2s mark and lift off around the 8s mark. Coincidentally, you can hear a metallic ringing at 2s mark that ends at 8s mark. It usually starts with a squeal and turns into a ringing. I can get it to happen repeatedly. It only happens while cruising and application of light throttle. Doesn’t happen with heavy throttle.

 

I plan to show it to service on my next oil change. Appreciate any input.

What ringing????  I here a little thumping but no "ringing".  What's your definition of ringing?

I should probably have mentioned it's more discernible on headphones. It's not louder than the road noise but it's there starting at the 2s mark. In the recording, it almost sounds like the noise crickets make. In the truck however, it sounds more like ringing. Hope this helps identify it.

I unfortunately did read that whole thread. I don't believe it's related to what i'm hearing. There was a guy (forgot his name) who provided a recording of the jingle and i confirmed it's not what i'm hearing on mine. The conditions that cause mine to happen is different too.

Can't hear anything except road noise. Even with headphones.

That's 0 for 3. Maybe i am indeed going crazy. ?. Thanks for giving it a shot though.

A co-worker of mine who can hear it pointed out something to me that i hadn't thought of. He said the ringing is fairly high frequency and that some people can't hear that high. I obviously don't mean any disrespect by that. Will definitely need to keep that in mind when i play it for the techs. Thanks to everyone who gave it a shot.

Crickets chirp frequency is a wide range of 2KHz to 8KHz from a quick google search. Doing some sound analysis on the recording, as far as i can tell, the ringing is around 9KHz. I'm curious if you were able to hear any ringing at all in the recording. Try listening above the road noise, if that makes sense. 

 

BTW, this is not meant to be a hearing competency test, lol. I'm just trying to figure out where this sound is coming from.

Alright folks, one last attempt. This time around, I recorded it with the mic outside the truck which I think is clearer. Previous recording was done from inside the cabin. As before, it's more discernible with headphones. Please give it a listen if you can. I appreciate any input. Thanks.

      2013 2500HD 6.0L intermittent no crank no start

      By linc45bn · Posted

      I've got a 2013 2500 6.0L Flexfuel. Drove the truck earlier today with no issues. Went to run an errand tonight and noticed key fob wouldn't work. Figured battery was dead, so replaced fob batter. Still wasn't working. Grabbed my other set of keys with the other fob and that one wasn't working either. So I manually unlock truck and insert key. Interior lights come on, dashboard lights up, turn key and truck starts. Turn truck off, like a moron, and try starting again. This time no crank, no click, no nothing. Lights still come on and dash lights up, but now I'm getting a service 4wheel drive, service tire monitor, etc. Check voltage on battery and Im showing 12.2v. Throw my battery charger on it and give it 15 mins and try starting again. But still no crank no start. Decide maybe its a bad battery, run to autozone grab a new one and put it in. Same issue. Disconnect battery and let it sit for 15 mins. Try again and still nothing. I had managed to roll the windows down earlier as its a humid night, but now I can't get them to roll up. Power locks are also not working now. Then randomly I try the key again, and it fires right up. Immediately I roll up the windows as we have nothing but rain forecast this week. I shut it back off wait 30 seconds and start up again. Worked a 2nd time. So turn it off, start putting things back together. Try one more time, and back to no crank no start. And now the car alarm starts going off. Had to disconnect battery and leave it that way for the night as I don't think my neighbors would appreciate my alarm going off again tonight. Any thoughts or help would be appreciated.

      GMC 1500 Illuminated Front Grill Emblem REPLACEMENT.

      By Peoplemvr · Posted

      Hi there.  Long time lurker, first post.    i have read the previous posts regarding the water ingress problem with this emblem.  I bought my 1500 SLT the  summer of 2025 new and after reading the MANY problems with these emblems failing I decided to install one anyways.  As per a YouTube video, I sealed ( or tried to) this sign with silicone sealant around the outer perimeter joint and the holes that were already somewhat sealed on the rear plate of the emblem.  And installed the connector assembly using dielectric grease on the connectors. The installation looked great and worked well for about 4 months……then FAILURE.  Grrrrrr…… I live in the great white north and wash my truck weekly in an automatic car wash  to keep the salt off.  Let me tell you that removing the old, failed emblem is a whole different animal than removing the OEM individual letters without removing the grill assembly. Mainly because the illuminated logo is built differently than the original letters which  you can remove the red surface lettering with a knife or some kind of blade which gives access to the tabs which hold the logo onto the grill. So I had to essentially destroyed the old emblem to remove it. Doing so killed my chance of doing somekind of autopsy on the failed , old logo.  But there was plenty of water inside when I ripped it apart.  Prior to installing the new assembly I tried it with the old harness and it works fine.   Does anyone have any insight as to where the water is getting into this emblem? I intend to seal the new logo with slow curing epoxy this time around using a syringe.  I think this newer emblem may be an updated unit which I hope GM got the vendor to fix. It has an October 2025 date on it.    If this one  fails,  I am just going to revert back to the non-illuminated letters….AFTER PULLING THE GRILL.    Any thoughts on sealing with epoxy would be appreciated. Thx!   Doug

      PS: Here's pic of the 2014 wheels I'd like to run when it's not winter. Stuck my finger around new wheel caliper setup. Very little clearance. I suspect these won't fit, but won't know for sure till I try.   Edit: And my first mod. Stubby antenna from the old truck.
