My neighbor got the new i7 and the first time he tried to DC fast charge at an Electrify America station it threw a bunch of codes on screen and put his car in Limp mode. The dealership had to clear the codes and ended up flashing the firmware and erasing all of his settings and reverting the car to how it was configured at delivery. It's probably BMW being overly cautious and not that the charger could actually harm the car, but I can say I have never had a Supercharger disable my Tesla requiring a tow. I have only ever successful DC fast charged my Leaf about five times, I have however tried to DC Fast Charge it at least a dozen but the chargers are broken more often than not.
