Default new 2.5 shaking when idling

i just got my new car for 3 days.. and i already notice some shaking when my car is idling.... these things should happen to an old car right.. but i just got my car for 3 days... i m wondering what's happening.... should i check it up at the dealers?.. or wait for the check up at the break in point?..

Is it just kind of vibrating a bit and not idling perfectly smoothly? That's totally normal for Subarus.

Like Mike said, it's almost certainly normal. A Subaru's boxer engine has a little bit of lumpy vibration at idle.

The Subaru design lends itself to a slight wiggle at idle but is very smooth just off idle and through the rev range....also, being new...it may take a while for it to smooth out as it breaks in.

Running 89 octane gas instead of 87 will calm down vibrations on the 2.5 N/A engine, specially at mid and upper revs. (as smooth as a V-8 when cruising on the hwy). You may loose some low end torque though.

Vibrations at idle don't bother me much, so I haven't paid attention to see if the octane makes a difference there.
