I asked the same question a month or so ago. Mine is a '22 as well and has been doing it since day one. I had a 2020 with the 2.7l turbo as well and there was no such noise, I know they have revamped the engine since then, so I don't know if that has something to do with it. I've gotten used to it, but it's still a bit concerning. The feedback through the radio speakers comment nails it, I couldn't really figure out a good way to describe it. Hopefully it's nothing that's going to cause problems down the road.

After listening to all the videos and audio clips in this thread, your whine is definitely different than mine. Mine only makes a whine when I am accelerating, and its definitely the turbo spooling. The whine in this thread sounds more like an electrical whine or something. Hope you get it figured out soon.

Hi, same problem with silverado 2022 2,4L. Bought it a month ago, and it's been doing it since day one. Tried it twice on two different ones before buying, and the 2 others didn't make a sound. When I told the vendor (that was sitting next to me while on the test drive) that the one he delivered me was making the whine, he told me it was the turbo. The thing is I was with him when I tried the other and it was completely silent. 

 

I have an underground parking space and when the windows are down, you can hear it very clearly from outside and inside the truck. To me it sounds like an old car that's about to break down, and I find it very concerning. Feels like I bought a 50 000$ lemon.

 

Is there any new development on the subject?

I’ve got the same whine, 2023 Sierra. I’m not terribly bothered by it, but it’s annoying to think that GM doesn’t really know how to get rid of it, or doesn’t care to. Here’s hoping it doesn’t become an actual problem with the engine.

Little update on my last post, 

 

I went and did a test drive with the head Mechanic at my local Chevy Dealer. He instantly noticed that something was wrong with the whine, it's not suppose to be noisy, even at cruising speed.

 

According to him, it's transmission related, since they never had problems with the engine. He booked me an appointment in may to replace the piece of the transmission that is faulty according to him. He seemed to know where the issue comes from.

 

I will update you once the change is done and let you know if it worked.

Getting the same issue with 3.0 LM2 10spd at 17k miles. Does it at idle in P and whine changes pitch with RPM. I'll make an appt.

There is a new TSB dated March 2023 that recommends replacing lower crankcase extension. I believe it applies only to 2.7L engine.  The TSB number is 23-NA-015.

 

I had a similar complaint regarding my 2023 Sierra 5.3L. The dealer mechanic thought the TSB would apply to my truck and gave me a copy of the TSB. However, their shop foreman later said that new TSB applies only to 2.7L and that whining noise I have is normal for the 10 speed transmission.

Update on the appointment. After a week of work on it, they tried changing parts on transmissions and on the motor with no success. They did acknowledge at first that the sound was off, but ultimately they couldn't find the fix and ruled out any major problem. I just received a call from them saying there's nothing more they can do, it's now suppose to be normal and that I should come and pick my truck back.

I'm starting to consider making a complaint and trying to get a new one, if it's even possible...Last time I tried to write to GM, they wouldn't help me, redirecting me to the dealership. I will try and see if they could do something with what alexTheMan said on TBS 23-NA-015 tho.

Its balance shaft gear whine.  It is considered NORMAL however there are SOME trucks exhibiting very strong gear whine and GM has a fix, replace the lower crankcase extension assembly.  The LCE Extension is the piece that the lower plastic oil pan attaches to.  

 

Dealer can pull this up in GM's system and THERE IS VIDEO from GM they can play showing normal whine and excessive whine.  Noise affects engines with less than 10,000mi on them.

      Fluid Change Questions

      By Chuck FB · Posted

      There would be one way of determining the quality of the factory oil although probably more than a typical oil lab test, and that would be to draw out some oil from a new truck and send a sample to a lab that could do a more elaborate test of the oil. The issue with too little oil in the diff may not be the lack of lubrication of the diff bearings and gears themselves ( although a lack of oil volume for cooling ) but the wheel bearings because at some point the oil would be too low to properly get onto the spinning axle or fed along the axle tube. That was the claim by the local dealer from a couple of trucks in recent years that had the wheel bearings fail and they figured from lack of sufficient oil due to a severe underfilled diff and some of the bearing material made its way to the diff and it got damaged as well so the axle housings were just replaced on warranty. But your right that if the diff is over filled by whatever margin that it causes more churning of the oil than is desirable and that is no good either and can cause a pinion seal to leak. Also old oil I believe can tend to loose some of its properties like antifoaming and another good reason to change the diff oil every so often.

      I would be surprised if the diff's were not filled (with the cheapest gear lube) at the axle factory before being shipped to GM.  If you ever watched them building trucks they install the axles and all suspension parts with the frame upside down and then turn it over before its time to install the engine.     Too much gear lube in a axle can be worse than not enough especially with a lower quality GL where is get whipped up with entrained air (foam)  weakening its ability to lubricate.

      This is the 6.6 gasser section of the forum, you should either delete or modify your previous post as it is misleading for anyone looking for factual information on their 6.6 gas engine.

      Wow I'm in a pickle. (Broke down truck) and a story.

      Well....I've done my first intake gasket. Probably wrong, but...we'll see?   Ultra black on the china walls and 1/4" up onto the sides of the intake gaskets. Permatex High Tack (couldn't find Gaskachinch) on the head side of the intake gasket. I read wrong and it says you're supposed to put it on the mating surface of the head, not the gasket. Hoping it's like a PB&J sandwich where it doesn't matter what side the PB goes on so long as there's jelly. That crap is messy/sticky and I got a dab or two on the intake port openings, tried to wipe it off. Hopefully it won't be a big deal and will only aid in sealing.   Per instructions I left the intake (top side) of the gasket dry except for a light smear of RTV around the coolant ports. Wiggling the intake in there was a bear but I had help to free me of surrounding wiring/stuff but I was basically able to set it straight down lined up with the bolt holes.   I did not think to wait until the RTV skinned over but there probably was 5-10 minutes while it sat before installing the intake.   Bolts finger tight first. Then, followed the Chilton's manual pattern to snug them to 15 lb-ft.   Waited a little over an hour, and then did the final torque in sequence again to 35 lb-ft.   Yesterday I replaced the fuel pressure regulator and got my new "nut and bolt kit" (fuel lines) installed. Damn GM used security torx on the spider, which I don't have, so I got scammed at the local HW store for an off-brand security Torx bit set.   The new driver's door mirror arrived yesterday, so, there's a chance this thing could be running and road legal tomorrow? I don't want to get my hopes up.   This will be my first time stabbing a distributor, too. Although, lucky me, someone else marked the old distributor for removal previously, I did see that. (Someone's been here before!!). Engine is still at TDC so it *should* be just a matter of transferring the mark to the new dizzy and rotating it into place.

      2027 GMC Sierra: Official Discussion

      He has his dad’s newer truck he’s put away. He has several old cars he rotates between him and his family. I’ve seen a restored square body and a SS Chevy truck he’s sometimes drives. He did raffle off a new suburban recently. As much as he is watched if he drove new stuff as a rule we’d know it. It would be fine by me. I don’t care what people prefer. I got one more new one in me. I’d rather my wife get one. I can’t get her out of the Genesis. Don’t tell anyone. I want her to get an electric truck. I want to put a generator in the back. Just because. She hasn’t bit yet.
