I noticed this on mine (just 3 days old) but it is slight whirling noise that comes on and off; probably noticed more now that the fuel tank is emptier. The tech confirmed it and thinks it's the low pressure fuel pump since it is coming from the back of the car and I'll have it checked soon. It is more annoying than anything else.

What I'm curious about is when ppl w/ this prb has the low pressure fuel pump replaced, does the prb actually go away or reoccur? Or is replacement not the solution but something else (software, etc)?
