Has anyone experienced this engine noise '21 or '22?

[mightymouse]

After research, it seems a lot of customers ('21 and '22s) have this engine noise without resolution from GM service. This noise is usually isolated to automatic drive, but isn't present when using manual shifting. I've resorted to the latter in regular traffic as the noise while in automatic can be a head turner. I've attached a video link of the engine noise someone else posted on youtube. Have any of you experienced this noise? If so, what was this issue? Was the issue resolved?

That’s a great video but I haven’t had that yet on mine. kinda strange.

I've heard nothing like that on ours. Don't have auto start/stop though thankfully but who knows if that makes a difference or not

Never heard that on my RST and about to hit 13k miles on the odo.

Try it with the A/C off. Sounds like the compressor clutch engaging/disengaging.

Mine has sounded like that from day 1, I got it in August 2020 and it now has 16,000 miles on it. I think it's exhaust valve and/or manifold noise that is characteristic, not something specifically wrong with ours. I hear it at drive throughs on other GM trucks and SUVs with the 6.2. I previously had a 2015 Escalade that made a slightly different sound its whole life.

My 22 has done that since day 1. I only have 1,200 miles on it, I was going to ask about it at my first oil change.

It sounds like a loose belt. My old '00 jeep cherokee would do this on startup until the rust on the idler pully bearing broke free every morning.

I have auto stop and have not heard that. Is it the 6.2? We have had our Denali 3 months and it has 2500 miles. I will keep an ear out for it.

I took the vehicle in and service was unable to reproduce the noise. When time permits, I may take it to another dealership for a second opinion as the noise is consistent and engine is getting louder at startup. I'm unsure if the two noises are connected, but it does sound like it could be a belt.
