| Description of the problem | On march 10, 2012 my wife started the aforementioned vehicle and immediately began to smell gasoline fumes in the passenger compartment. As she exited the parking garage, the toxic fuel smell became unbearable and she immediately turned- around, re-entered the garage, quickly shut off the car and exited the vehicle for fear of fainting and / or an explosion. The mb rep explained to us that there was a failure in the fuel delivery system; which is accessible under the backseat of the passenger compartment; and the leakage caused fuel to be pumped into the passenger cabin and accumulate under the rear seat; thereby saturating the insulation, carpet and rear seat cushions. The mechanics replaced the fuel system; and reiterated that the gasoline leaked up into the passenger compartment (from the faulty fuel delivery system located under the back seat of the vehicle), saturated the carpet, the floor insulation as well as the actual seat cushions. In our opinion, a critical vehicle design safety feature (in the event of a collision) is not to permit fuel to be pumped into the passenger compartment; which would increase the likelihood of an interior explosion, and at a minimum impair the ability of the occupants to safely exit the vehicle, before succumbing to toxic fumes. The dealer service rep? S response was: ? Mb has determined that the safest place to locate the fuel delivery system is under the back seat of the vehicle?. I implied that his response was not acceptable. Interestingly, the mb dealer service rep called us and said mb inc. Would cover the cost of the repair. However, repairing the passenger compartment damage and defective fuel system does not alleviate the cause of this dangerous situation. |
