When the car is running, the battery is ~13.3. When I left it alone for a week, it was 11.9 before starting it up. After only driving for about 10-20 minutes, it's up to 12.3 with key in ignition/motor off.

I figure the low voltage is due to minimal use in the past 8 days.

Was able to reset the handbrake with the release tool in the trunk/left left panel. Now just down to these codes.
