Single-ignition coils… a weak spot???

Hello friends, on my VW Polo, built in 2010, 1.4l, 86 hp, km stand 35000, the third ignition coil has already failed. Can you perhaps tell me if this is a weak point of the VW gasoline engines? And if so, what is it all about that so often? Have you asked one of my work colleagues, who drives a VW Golf V. also with him two ignition coils have already been renewed. Do other manufacturers have to fight with it too? Or is this again a consequence of the so often z Is it necessary to save money at VW? Thank you for your answers.
