There is a loud rumbling noise when I accelerate, and upon research, I saw online that a lot of buyers are having the same issue as I am. It just doesn't sound good, I owned a 2005 Nissan Altima a few years back and this car sounded better than my current 2013 Altima. Just sounds like an old beat up car and it is only a few years old.
