Noise like small motor driver's rear wheel well?

20013 2.5i SAP Outback.

Twice I've heard this sound like a tiny electric compressor motor running. First time I thought it was something in the garage with it stopping before I isolated it to the car. Today I notice it again and I isolated it coming from above the driver's rear wheel like maybe around the spare. By the time I opened the garage to open the back for investigation the noise had stopped.

Any clues?

It's normal but my CRS just kicked in and for the life of me I can't remember what it is that makes that noise. Help!! EVAP system???

The evap system is just letting out a bit of "steam". Totally normal.

I've also had this sound from the fuel pump on other vehicles.

(Disregard thread title, has nothing to do with parking brake)

It's difficult to attribute a noise to the parking brake that occurs while your'e not actually in the car.

My electronic brake was possessed, so it wouldn't have surprised me if it activated itself when I wasn't around

Crazy - I noticed the same noise coming from the rear of my car - while parked in the garage & not having been driven for several hours. What is it? Sounds like some sort of motor, but it's spooky when the car isn't even on.

My Scion had a vacuum pump on the gas tank. It would run for a few seconds about five hours after shutting down the engine. The purpose was to check for vapor leaks in the system. I suspect this is what you are hearing.

Most likely fuel pump -- nearly all fuel injected cars / motorcycles have one in the fuel tank. I hear it on my motorcycles during every start. Don't know anything about that vacuum pump mentioned above -- never heard of that.

Glad to have found this Forum- I was taking the garbage out through the garage this evening and heard the whirring noise from the wheel well. It was nice to find an answer with a few clicks of the mouse.
