ENGINE KNOCKING/PINGING

2009 Acura TSX

Engine Mechanical problem
2009 Acura TSX 4 cyl Front Wheel Drive Automatic 2526 miles

I bought a brand new 2009 TSX and noticed a very slight knocking in the engine between 2300-2500 rpm. Sounds like it is coming from the right side, deep in the engine. This started around 2300 miles (when I noticed it anyway.) It occurs when going up a hill or on a strait-a-way. Can't hear it unless radio, heat/air is off. Got on the computer and researched it to see if anybody else is having the problem; they are. Even in Austrailia and Europe, people are noticing this under the exact same conditions. Acura is saying it is " characteristic" of the engine and are " looking into it" with their engineers at the moment. I have always used premium 93 fuel, so gas is not the problem. Does this sound like something that will get worse? I am considering trading it immediately, but will hold on if I feel like it is something simple that can be adjusted via a recall.

Thanks for your input : )
