Electric shock

Hello guys and girls, For a good 3 weeks my wife (and I myself also often) gets a shot every time leaving the Punto as if when driving a bit statically recharge To the data: GP 1.4 8V, year 2007, 78,000 km on the clock and as is in the original condition. So radio, lights and co, everything like when buying. Vllt is to mention that it is my wife’s car Vllt you have an idea if necessary same experiences… Thanks already for the answers… Greetings digi
