First had the dimmer reset on my instrument cluster. Next couple starts my clock reset. Then I got a battery discharge warning. Then a battery low warning. Then the car died when the dealership tried to start it to test the battery. Replaced my battery. $360. I gave them the SIB about the cable, but figured if I had a cable issue it would have died a long time ago. Car's been running great since. Three other M3s were there for the same thing.
