The problem is this. ALL hardware is prone to failure. Without actual statistical data on how common the problem is searching for it is not going to mean much. You will find what seems a huge problem by just looking at a small sample in a forum like this because, well, out of the millions of drones out there this is where they would come to discuss their experience. Be like saying all cars have engine problems in a forum on engine repairs. I would bet a good portion of the time it's user error, the rest is a hardware failure...which does happen, unfortunately. I would not sweat it because, well, nothing you can do about that really. As long as DJI recognizes the problem and replaces it best you can do.
