HELP NEEDED - Electrical with codes

[Okierunner69]

2010 limited 137k miles

I have been having a ton of electrical issues the last few weeks.

The most prominent problem is intermittently my push to start will not turn green and the car will not start. All lights works, key fob unlocks doors, car will go into acc, just won’t start. If I disconnect the battery for awhile it will start just fine. Scanned for codes and got P0504 which is brake switch A/B, P1603 which says engine stall history, and C1422 which says VSC interruption for engine convenience.

Today I was driving and the AC light started flashing and the AC started blowing warm air, then shortly after the traction control and ABS lights came on, scanned for codes again and got B1422 which is the AC compressor, along with P0504 again.

All of these issues are intermittent, car will be fine for a couple days, then all of a sudden these issues will occur. Any help would be appreciated!

let's start with the obvious question; do you have a pedal commander or anything like that, have you done any mods where you've tapped into break line or fuses. do you have a remote start?

the brake AB code probably means you need a new brake switch. when you press on the brakes do your rear lights light up? intermittently? do they not come on at all. if not then you most likely need a brake switch . it is not a difficult DIY. I would maybe start there and move from code to code
