Misfiring in every cylinder. Kia Forte GT ‘22 at 43.3k miles

Earlier my check engine light came on and when I got the code read it showed every cylinder misfiring. I assumed the check engine light came on because my gas cap wasn’t tightened all of the way.

I’m still under warranty and unsure if it will even cover this. I had a spark plug issue at 5K miles. The spark plug code showed in the Kia app but this isn’t showing up at all which is frustrating to me.

I always get my oil changes on time and I’m very careful about it. Can I please get some advice as I’m stressing out.

Thanks in advance.

I’ve never forgotten to screw my gas cap on before but since this is the engine repeatedly misfiring I’m not sure where to go from here. Any advice is welcome.

Edit: 1.6L turbo engine with 4 cylinders

Diagnostic codes were: p0301, p0302, p0303, p0304
