Other Fuel System Tank Assembly Problems of Mercedes Benz ML350

Week of June 27th, I started to note gas fumes coming from my vehicle. Given, I had recently filled up on gas tank, thought it was due to "burn off". . . On July 2nd, took my vehicle in for oil change and they noted that they could detect gas fumes coming from under my vehicle and advised to take it to dealership in ASAP. . . Same day, took it to dealership and after a full inspection of my vehicle, they advised me the fuel sending unit was braking down and needed to be replaced. They advised this was so incredibly rare and should not have occurred. Driving my vehicle was a hazard and could have exploded. Given this is my main vehicle for me and my son, this is very concerning to me!!! and nothing should be braking down at 70,000 miles. . . My extended warranty did not cover it and it cost me $2000 to have it repaired. Again, no one can advise how this occurred but no one I have spoken to can give me a reason but nothing should be deteriorating on a luxury vehicle.

Car suddenly developed extreme gasoline odor after a brief 20 mile trip. Cursory check did not identify source. Upon return trip, same extreme sickening odor returned. Upon pulling into garage gasoline was visibly pouring from underneath the car and pooling on ground. It looked to be coming directly from gas tank area but could not determine main source as it was sprayed throughout the undercarriage. Aside from the nausea, this clearly posed a significant fire danger and was immediately transported to the dealer – awaiting repair costs now. There have been no other incidents or external reasons that might have led to this (such as running over something or hitting something in the road). After doing research this appears to be the same type of problem that has been, and continues to be experienced by other owners due to a manufacturing defect.
