Got some battery error codes after not closing fuel cap properly. Should I be worried?

    As far as I know, these codes weren't there a week ago when I checked for error codes.

    My main question here is, I wanna know if these are typical error codes thrown when you don't properly close your fuel cap and you get a CHECK HYBRID SYSTEM with yellow check engine, or if it just happened that I discovered these new issues when I got the check engine and decided to check on the OBD2.


    Looking online, these codes seem to be pretty serious:

    P2532
    • Ignition switch failure
    • Powertrain Control Module (PCM) failure
    • Wiring issue
    U0129
    Lost Communication with Brake System Control Module (BSCM)
    U0164

    Lost Communication With HVAC Control Module

    After properly closing the fuel cap, the check engine got away, and the CHECK HYBRID SYSTEM aswell, altho I had to turn the car off and on again a few times. I erased the codes on my obd2 and they haven't shown up again yet for the rest of that day's drive. I was able to go home without any issues, I even tried the breaks on neutral since U0129 seems to be related to breaking.

    Disconnect your 12v battery for an hour and do this reset
