In fact it happend the very first time for me when I received the car. I was a bit concerned but the salesman said me that they had some problem with their charger and it may be that it was the reason. They fixed the problem by taking the battery cable off.
After this second time I left the car...
I just bought Macan turbo and after the first week I met a problem with the charge ports - they do not open. I returned the car to the dealer´s service and now waiting for their reaction to this problem. It is not acceptable at all that expensive car like this has this kind on problem.
