Shouldn’t matter if it does it when stopped right 😊

To be fair, your original post was severely lacking any specifics or details. You didn’t mention a speed, only distance (??), nor where the sound is coming from, etc. You can’t expect any real results like that, and those giving advice are just throwing things out with no real knowledge.

You are so correct my sincere apologies
sorry.
yes you can be stopped but as long as it’s in drive it still occurs but if you put it in park it stops
sounds like something unhappy in transmission

Maybe take it to a dealer? Its under warranty.

It’s been there they replaced the brakes and drilled holes in the exhaust ( hacks )

The helicopter noise sounds like an exhaust leak most likely under driver or passenger side seat. Why did they cut holes in the exhaust?
