No Electric power in the interior of the car. I have checked all of my fuses, and they are all good but I do have lights on the dashboard and radio and climate control center but no lights.

I have error code E52, E67 and F40.

So, none of these codes can cause the electrical problem you are having.

E52 - Memory Reset
E67 - Cruise - Servo Position Signal Problem
F40 - Air Mix Door Problem

I would test the circuit breaker #24 at the fuse block at the left side of the dash.
