Hissing

Whenever I turn my car on or off, the first few or last seconds it hisses. I don't know if it's a leak because there are no leaks in my engine bay and it stays cool in the car, it's been doing this for a few months with no major issues...has anyone else experienced this issue and how did you fix it?

a vacuum leak will hiss.
pop the hood with the engine running and follow the sound.
