“My vehicle is emitting a very strong fuel smell and possible leak coming from the fuel pump. This is located under the rear seat, which had a recall. I believe that the item is faulty and should replaced once again. I reached out to the dealership and to mb corp; but they do not want to take responsibility for their faulty design and product. The vehicle is not safe to drive with the strong vapors, which are dangerous to health. …”
