Hi. The sound is with the vehicle on. I hear it underneath the car right in front of the rear tires. Its not the sound that comes on hours later after turning the vehicle off like in the manual. Its most noticeable in a garage, which is where I heard it first.

I took it the Subaru dealer and one of the master mechanics said it was just the cvt regulating the pressure. I asked if its going to hiss all the time and he said “yes”. Weather doesn’t affect it.
We took it for a test drive and everything sounds ok and checks out. ?

The sound while the car is off is normal. Disconcerting, but normal.

The OP is hearing a hissing sound only while the engine is running.

I heard the same noise today on a brand new Outback with 270 miles on it. Its not as loud as it is on the Ascent but it is there. Normal Cvt noise. ??

I'm glad that you have some satisfactory resolution from the source, so to speak and I hope that your understandable anxiety is now reduced. Cars in the 21st century are quite the marriage of mechanics, electronics & technology, aren't they! We went from "purring like a kitten" in the 20th century to "hissing like a snake" in the 21st! May you and your Ascent share many years of happy adventures together. Safe travels! (Does he or she have a name, yet?)
