2016 Subaru Outback - Whistle When Accelerating

Has anyone experienced a faint whistle when accelerating? I’ve only noticed it on neighborhood streets at lower speeds. Car has ~76K miles on it. Thank you!

Yep, I’ve had several that whistled. Where on the car is it coming from? Did it just start? Did you own the car a year before the trouble? (First days w/ windows down locates lots of “new” problems.) And it does it only when accelerating?

I’ve heard mechanical parts make a squeak that could be called a whistle. A leak in the exhaust or engine intake might whistle. If you could post a sound clip, it would help, too.

The air filter housing and its associated ducts and connections?
