I have a new outlander and starting about a week ago it is making a loud whistling sound. The faster I go the louder it gets. It so bad that people on the street stop and look at me. No idea what it could be. Should I take back to dealer?

 

Yes take it to a dealer

 

It can be whistling belt or brake pads or even turbocharger if you have one.

What happens if you press accelerator pedal while standing still on neutral gear?
