Default Pop then hiss sound

I drive a 2015 carrera. I was driving in yesterday and heard a pop then hiss immediately after. I was going over a speed bump at a reasonable speed at the time and it was prob 30F out but I had warmed up the car for a couple minutes. There was no sign of anything dripping and the check engine light has not come on.

I'm posting to see if anyone has any idea as to what happened, if anything and if I should take it in to be checked. Thanks for the help.
