I have an odd sound on my hatch, its like something (metal) broke and rattles when i start out in first gear but then goes away in every gear after....It DOES NOT happen when i rev the car in neutral or at a stop.....

What could it be? Its under warranty still, ill have the dealer check but does anyone know????

 

Sounds like your tranny is falling apart not your motor

 

how loud is it?

 

possibly a bad throw out bearing fix it ASAP and dont keep driving it unless you want to buy a new tranny
