DC to DC converter problems?
 
I'm working on a all wheel drive 2007 Ford Escape Hybrid with only 30k miles. The 12V battery's voltage gets low and the brake is gone when A/C is on for over 30 minutes while driving locally. Not sure what caused it. If DC to DC converter has issue due to the heat, shouldn't it have some DTC code? When I scanned the codes, I only found low voltage and brake issues. I assume the brake issues are caused by low voltage. But what caused the low voltage? Have tried a new 12V battery but still have the same issues...,

Give this a look. It does sound like a heat issue.
