So I was at the drive thru earlier and i kept hearing a rattle i thought it might be the car upfront but it wasn't it was mine...when the car is on drive but i holding the break at a stop or something you hear this rattle it sounds like metal hitting something not sure what it could be....i put it on N and you dont hear anything only when the gear is on drive...

I bought this car preowned...i am so tired of having to fix things on it i think i need to trade in soon...ughh!

 

good chance its a heat shield above the exhaust, happened to me a few months back, i just tore it off. other option it to use self tapping screws.
