When a vibration suddenly starts to happen, it means that something is loosening. Usually it's a panel or a sheet of metal that's vibrating on it's resonant frequency, that's why it goes away with speed, it passed the resonant frequency.
It's very hard to find because you have to be under the car to see it. If you find something you suspect, tighten the screws or put a rubber band on it to test it.

The rattle is likely a loose shield or a bad catalytic converter. As for the loud banging, Have you checked the front U-joints behind the brake rotors. As for the Reverse noise? Auto or stick shift?

2004 Kia V6 Optima has loud noise when accelerating and decelerating - sounds like lawn mower

G'day mate , sounds like exhaust hiting , posible causes are from the front to back , boken / deteriorated engine mounts allowing engine to move about , exhaust shields ( thin plate moulded to exhaust shape and bolted on ) rattling about , finally exhaust mounts themselves are they in good order if not the exhaust will hit and bang . hope this helps

Rattle noise when I let go of the accelerator. The faster I go and then slow down, the louder the rattle noise

Have a look at the shrouds around your exhaust system, they are prone to shaking loose and rattle on over run.
Try giving your exhaust a bang ( with your hand when it is cold) and see if it causes the noise . Follow the noise.
Sometimes the baffles fall off inside the muffler and rattle around inside too.
Happy hunting!!

I have a noise that sound like it is coming from my drive shaft but i am not positive its not quite a GRINDING NOISE ALMOST LIKE A HOLLOW RATTLE

check the fluid in the rear. We just replaced a rear on the same exact vehicle. Does it hum going down the road? Does the humming increase with speed? Also check the exhaust. Chrysler products are famous for their ratteling exhaust.

Acceleration noise

Unless you are hearing an exhaust rattle of some sort, suggest higher octane fuel or check your timing.

Rattling noise from front near alternator

Hi.
I think the problem is the power take off for the front fan ,steering etc. Underneath the middle of the car you will see what looks like a small propshaft pointing towards the front with a doughnut shapped mounting bolted to each end. These rubber joints wear and rattle on tick over or low revs cost is about £40 for the 2 from Japarts
Takes about 2 hours to change.Hope this helps Good luck
