I have a 2003 Chevrolet Malibu; when I started driving, i found that after it reaches over 20 miles per hour I started hearing a clunk/bang kind of noise from the front of the car. Does anyone have idea what going on.

 

I'm gonna use the following debreviation = MBL (might be loose)

so here it comes:

your exhaust mbl
your protection cap mbl
your frontspoiler mbl
your airfilter mbl
your watertank for the windows mbl
your radiator mbl
your second radiator mbl
your airco pump mbl
your powersteering pump mbl
your battery mbl
...

get my drift?

Check for loose parts first.

 

And I keep coming back to the intermediate steering shaft.......those things are pieces of Sh** and the electric assisted steering has no road feedback feel. Might be a strut too (20 mph). Get a trusted shop to look at it and watch for BOHICA.
