I was having Random ESC, ABS and theft lights late last year. (I didn't pull C codes). Sometimes different combos of those lights. Sometimes just lights, sometimes drivability issues, it was a huge wtf. After a number of different attempts to repair looking for electrical gremlins I stumbled on bulletin 13036. (Google it, I don't have a copy). It had been done before, but I figured it couldn't hurt to look into it. Some of the symptoms matched, and basically described poor connectivity at BCM.
Took 20 minutes and $15 worth of dielectric grease.
The short and sweet is to disconnect the brake pedal switch, fill the cavity with grease and reconnect. Pull BCM connector, fill cavity with grease, and reconnect.
Boom! Fixed it.
I can't say it will fix your issue, but it handled mine.
