Random loud hiss in my 21 Cherokee.

So the other day I had the AC on while driving and I heard a hiss somewhere behind the dash and I heard it over my music. I didn’t hear it after that until tonight, about 4 days later.

I didn’t have the AC on but had the air recirculating button on. I was backing into a spot and my radio was turned down and a loud ass hiss again behind the dash lasted about 3 seconds probably.

Sounds like when a tractor trailers air pressure gets too be too high and it bleeds out.

Reading online, some places say it’s normal other places say no it’s not. I’ve never had this sound in any previous car. I’m taking it to the dealer tomorrow for a different issue so I’m going to mention it no matter what.

Just curious if I should expect sitting at the dealer tomorrow if they gotta rip stuff out.

Brand new less than 300 miles.
