My new Honda Accord has this weird knocking sound that is similar to a diesel engine. I brought it in for inspection multiple times and the mechanic told me it is absolutely normal and the engine perform to specs. I don't hear the same sound on a similar Accord. Does anyone have a similar problem? What could this sound be? See link for video.

I can hear a little type of knock. For the most part is sounds normal, like sewing machine.
