Multiple Trouble Codes

Hello my Prius brethren. I have encountered a problem of multiple trouble codes recently and could use some advice.

My 2013 Prius trim level 3 was running fine until a week ago when it started coming up with the check hybrid system warning. I would reset it and it would run fine for a few days before setting the warning again. Recently it won't make it a mile or so until setting it.

Also it sets various lights on the dash. This morning was a traction and ABS warning which graduated to a full hybrid alert. The speedometer will randomly show speed, then zero, alternating. Also low oil pressure (it's good), seat belts, etc.

I replaced the 12v battery as per suggestions here. No help. As I said the warnings were intermittent but are now constant.

I ran an OBDII scan and these are the codes showing. Any suggestions on where to start looking for be greatly appreciated.
