My new ST has about 1200 miles on it. The auto stop has ceased working correctly. Sometimes it does not come on at all at a stop, other times when it does come it, it shuts off before I touch brake/accelerator. I kind of have mixed feelings about this. I know some here have paid real money to get the damn thing not to engage. And I am not a big fan of this feature either. Should I go back to the dealer or be happy I got a "fix" for free?
