Is exhaling noise normal

Is it normal for the car to let out a loud pressure release noise from the engine compartment after you park?

Yes. It's the AirMatic system venting excess pressure.

Yep, and I swear, after I park in the garage... If I open a door 90% of the time, I will get an automatic exhale. This has to be somewhat normal, but some say it's not.

Mine does the same.
