You have a charging system fault of some sort. Here is the diagnostic procedure for the C0800 code. This is taken from the 2016 FSM but it should be applicable to your car.

I found the issue. it was a corrosion on the screw that holds down the Oil Catch Can. Super easy fix!!!

I experienced something similar. I lost power steering and got all kinds of codes. Turns out I installed my catch can as recommended on the main ground strap bolt for the steering. I moved the catch can with a modified bracket to the front of the cylinder head.
