2013 Subaru Legacy 3.6r ODB-II Codes

[ChaoticGood]

Hello, first time posting here.

I have a 2013 Subaru Legacy 3.6R Limited with a check engine light (flashing and occasionally solid).

AutoZone ODB-II codes show following:

P0300 - Random/Multiple Cylinder Misfire Detected
P0301 - Cylinder 1 Misfire Detected

C0057 - VDC Interrupted Due to Egi Reason
C0045 - TCM Malfunction
C0042 - Power Supply Voltage Failure

Would this mean that I need to change several cylinder sparks and coils (for the misfire)? Also, what do the C-codes mean?

Thank you.
