1 Other Fuel System Pump problem

Failure Date: 06/01/2020

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. Also, I am forced to leave the vehicle outside of the garage because of my fear that this will cause a fire or explosion, resulting in massive house destruction and possible death.
