Supposebly, they've seen the the Bulletin and tried the fix with my truck, but it's still noisy and they could do anything... No solution according to them. I find it very wrong that a brand new car is making such a noise

Do you know how to access the bulletin without having to pay the subscription fees? whenever I google it, the only website linked to it is: https://www.repairprocedures.com/bulletins/document/23na015/6265146.html and you have to pay a big amount almost daily

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.

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.

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? Urecorder_20230329_.m4a
