Noise with Honda Pilot

Sometimes when the tank is full I can hear the gas sloshing around when I

Good day,

I have a 2003 Honda Pilot with only 7K Km. Since I purchased this vehicule
there is a banging noise that can be occationally heard when breaking. The
noise is like something would be hitting the bottom of the car. In addition
to the noise you can feel the associated vibration. This seems to be coming
from the back hald of the car. This issue is intermittent which makes it
even more difficult to find the root cause. I had the dealer take a look but
could not find anything. I also did a quick inspection to see if there would
be anything loose and did not find anyhting either. One quick test I did
which seems to give me similar results is to put the car in drive, go
forward for 3 feet then appy the breaks abruptly. in 75% of the case when I
do this I can get the same sympoms.

Could anyone provide some insights on what the root cause of this issue is?
Can this be just be the fuel in the gas tank causing this?

Thanks for your assistance.

MRP.
