Like the title says, the button on my cable will not auto open the charge port. I can open the port by pushing on it (with doors unlocked) or on the touchcreen or even with my phone. Also I know the button itself works because it will release the cable when I push it and can still do the 10 pushes trick to rainbow the charge light. It would seem that it's a fault with whatever receiver in the car detects the button push on the cable. Anyone have an idea? I've hit the reset button on the cable but that's about it.
