Well they are all codes relating to the ABS module.
DTC C1241 - Low Positive Voltage or Abnormally High Positive Voltage
DTC C1256 - Accumulator Low Pressure
DTC C1353 - Front Increasing Pressure Solenoid LH Malfunction
DTC C1391 - Accumulator Leak Malfunction
Looking at the code setting criteria I would say the brake actuator harness has a bad connection and is sending the unit low voltage, that would set all of the first three codes.
The leak code could be related as well if the accumulator cannot produce enough pressure due to the low voltage and it thinks there is a leak because of that.
Being a hybrid and how interconnected all of it's systems are I would take it to a dealer. That is because 3 of those codes actually have specific OEM codes that most scan tools cannot read, which can give far more information that the "generic" codes you have.
