Hey, I just bought a new 2010 Forester and I was wondering if this is normal. I notice this odd sound with the windows rolled down coming from the engine. It only seems to occur shortly after I have shifted and have begun to accelerate or slow down, mostly during the lower gears, 1-3 and while running at lower-midrange speeds. I will hear a soft "switch" sound and the engine humms at a slightly higher pitch while running at the same speed. As a result notice 2 very distinct sound pitches from the engine.

very frequent when I switch on the AC, happens almost instantly, but it still occurs less frequent when the ac is off

Could be the ECU adjusting the throttle position for emissions purposes. Is yours a PZEV version? Even if it isn't that could be what you notice.
