brand new corolla with rattling nosie

[sdav19]

I just bought the 2005 corolla S about a month ago. it only has about 1000 miles on it. When i got in the car today coming home I heard this horrible rattling in the rear right of my car. It almost sounds like its near the back right tire under the trunk. It makes the loudest rattling noise when I accelerate or slow down, but is also there when I am idiling. Anyone know what this could be? I need help!!!

Thanks!

hmmmm....maybe it your muffler...those rubber things that holds them tight might have broken off or rip

It's defenetyly your exhaust, specificly your muffler or the pipe behind it. It might have disconnected. If the rattling is right befind the tire then it's the pipe, because it runs through there. Take it back to the dealer and tell them, technicly they should fix that for you for free, sinse the car is under warranty.
