Hoping someone has had this issue and can help point me in the right direction.

When shutting the engine off there is a air psst sound, like when disconnecting an air hose. Also when divining but could be an exhaust leak.

I have have no codes showing so I am at a loss. Can't really tell if coming from on side or the other. It does not have air bags either.

 

Were you running your air conditioner? Often compressed refrigerant will continue to hiss through the system after the engine shuts off if the AC has been running. You can test the theory by turning off the AC, running the engine for 5-10 minutes, and then switch off and see if the pssss sound is present or not.

No, a/c not running.
