Last week, when I changed the battery I notice some rust on the trunk floor to the right of the battery. I saw some rust around the round thing were the positive cable connect or go through the floor but I didn't look more closely at it and forgot about it.

I just open the plastic cap on the thing and off course I can't barely see the cable-end through the rust… I'm pretty sure this is the source of all my voltage supply error I had for a few months…

Maybe it's wishful thinking, zero dollar repair but it makes sense! I'll fix this tonight, if I can get home...
Good luck!
