However, why would such a major issue occur in a car with such low miles/usage? As I understand it, matters of this magnitude ideally does not occur in such a quality car, let alone in the cars infant stage or would likely happen at all! I was told sometime ago that Mercedes knew of this issue. I also searched the internet and discovered so many owners are having the same issue around the world. Mercedes has refused to correct, its defect it was well aware of! Who allows Mercedes Benz, the platform to see these cars to consumers, without resolving the issue. …
