I heard the same thing, but I assume the sound should be coming from the electric motor, isn't it? I also notice this sound more obvious when u press hard on the gas.

I'm on a CVT but yea, the IMA is going to give you a humming noise... When you hear it look at your assist display... It should correlate.

lol. I heard it as well And kind of thought i had an exhaust or something hahah
I thought it was from the exhaust when i first heard it within the first couple days, but I realized the "noise" get more noticeable when giving more gas and the IMA assist show more bar, then I realized it should be the motor.

Reviving this thread,
I recently heard this humming noise louder than usual, especially when you are going from standing start after the engine is on 'auto idle stop' (say on a traffic light).
Normally its not that loud.
Any idea guys?

I have a 2013 CVT (totally stock) and I have heard a hum when I was accelerating from a stop light. This is the second time I heard it. The first time I thought it was the tires on a grooved concrete section of road.

I only notice the humming noise when revving at a certain rpm. I believe 2400 rpm. But it only does it on occasion, such as when its cold outside or the oil is warming up.
sounds like you guys have heard it as well. phewww..I thought its just mine.

where is that noise coming from tho? the IMA?
