Hello. Help.

I have 4 codes on my 2013 G37xS. I’ve got just under 80k miles and no mods. It’s been at the mechanic for 2 weeks and they just released it back to me. It has no CEL but my OBD2 scanner shows 4 code. Listed below:
P0081
P1233
P1238
P1239

I think it’s an electrical issue because of the nefarious sunroof drain (that I was lazy to fix…I know shame me later) however I’m far from an expert. You guys know better so any input would help. I love this car so much and don’t want it to break down again!
