 Right from the purchase this was a problem car. The entire fuel system ( diesel ) had to be replaced, a warranty item. Then the front ball joints had to be replaced. This happened twice. This vehicle had fancy seat controls all of which FAILED. Brakes were bad and had to be fixed. The fuel injectors ( diesel ) failed and required THREE REPLACEMENTS. Yes, the almighty Mercedes Benz can still makes lemons. And I met people who had similar issues.
