roaring sound at 1800 RPM

[Rad10eng]

Recently I was driving my new Equinox on the freeway and noticed a loud roaring sound when I was driving at a consistent speed where the engine was at 1800 RPM. I am taking it into the dealer today. But my Son and I decided to try and figure it out ourselves. It appears that the noise cancellation system has an issue. When I put the car into manual shift and drive at 1800 RPM, there is a very loud 180 Hz tone that comes out of both rear speakers. It does not seem to do this at any other RPM. I am not sure how they sample the noise reduction, but I assume there is a microphone somewhere. There may be a phase differential error that is causing this. Hopefully the dealer can figure it out, it is very annoying. It mainly seems to happen with the rear seats folded down.

Yes, It is a 2025 Activ AWD Gas.

Well, now I am very dissapointed with Chevrolet! Just got a call from the dealer. They do not think that Chevy can fix this. They gave me the option of just disabling the feature. To me, that is nonsense! Shame on them.

The new Activ just became less appealing to me. Fortunately, since I work in radio. I can share my opinion with many morning shows around town. They LOVE to have things to discuss.

Wait, I'm confused.... we've been discussing a noise "the car makes", which we're trying to identify. What does that have to do with a microphone??? And where can this feature be turned off???
