There are a couple of stations near my house that give communication error messages and set DTC's in my car even though they charge other cars OK. My 2015 will not charge after one of these failed connections without clearing DTC's. Therefore, I recommend that you try several different fast chargers (and make sure you clear DTC's after each attempt) before concluding that your car is defective.
