For as long as I can remember I think (maybe slightly less apparent in the beginning), I've had this buzzing/rattling, almost quiet "mooing" noise I hear from the drivers side under the hood it seems like when I'm initially accelerating from a stop whether forward or backwards. It would still be in first gear and the RPM's are low (if higher don't think I hear it or if accelerating quicker).

I have no idea what this can be. I do have a subwoofer installed and heard that ANC needs to be disabled or you'll have issued but I don't have any issues unless this maybe is it, but also read that V6 doesn't have ANC so assuming this is irrelevant.. I did come across a bulletin at one point where there may be a noise or disturbance inside the vehicle at low engine speeds between 900–1100 RPM described as a booming, moo, or even a hoot type noise and it will be coming from the vehicle's speaker system, but not sure if this applies to me and all they do is replace the Bose amp apparently..but that does seem similar..either that or I found another bulletin about the fuel line could make a buzzing noise or something but that is heard from the passenger side and I'm pretty sure this is the drivers side.

I've had dealerships look at it in the past I think and one thought it was the hood alignment and that didn't solve it and other recalls they did never fixed like they said would, so what could this be? Anyone have this issue and any possible ideas or resolutions? Wanna see everyone's opinion before I bring this up to the dealer on next visit as well. Thanks!
