I bought the Siemens charger after doing some research and the fact that it looked more substantial than the Juice box and some of the others. The problem is that when it is done charging it won't release the nozzle. Or maybe the car won't release it. Point is, I have to put the charger in Pause mode and then do the emergency release method (pull while pressing the charger door open button). Has anyone had a problem of not getting the nozzle released on a regular basis? Thanks
