well, you haven't included much information, but most subarus have a whining sound in the lower gears while accelerating. Normal. If it gets worse I would suggest checking the tranny fluid or changing it to something else that might quiet it down a bit. (If anybody wants to speak to this it would be nice)

Could you provide some more info about this noise? ie. (under what conditions it happens, auto or manual, warm or cold weather, warm or cold car, etc)

It happens in all the gears(manual trans) but I just left the gym and it wasn't doing it! It just strted today and it's been really cold in DE lately it might have something to do with it. It was just odd for it to start now and I wondered if you guys had any info about this. Or if you have ever had thi problem! It's a really high pitched noise

If it keeps doing it on a consistent basis, take it to the dealer. It's new. Warranties are awesome.

I second that, i installed coilovers and got a lot of extra noise that i thought was the coilovers, but when i took the car in to have a clutch/flywheel installed i was told the noise was my rear wheel bearings. Those guys have a lot more experience with sounds and it'd be easier to diagnose in person.

When this happened to me in my 02 WRX it was the idler pulley. My boyfriend took a screwdriver and used it as a stethoscope to diagnose exactly where the noise was coming from. He put his ear to the end of it and listened. Might be worth a shot.
