Mitsubishi ASX 2012: Buzzing engine noise

There is a distinct buzzing noise coming from the motor in my 2012 Mitsubishi ASX between 1000 rpm and 2000 rpm when accelerating from takeoff. It can be heard when in neutral and stationary, so it's not the transmission. Nothing appears to be loose around the engine. Should I be concerned?

You need to try and determine where it's coming from. If it's a tinny sort of buzz it could be just a resonance of a part that's perhaps a little loose, and nothing to worry about, but if it's a more solid mechanical noise and appears to come from within the engine itself then it's perhaps best to get it checked out by a mechanic.
