Fuel is leaking from both sender units when tank is more than 3/4 full. Extreme fumes when car is parked in closed garage with a full tank. Smells like a large quantity of fuel is leaking. Paid for the same repair 20K miles ago, now same problem has returned. Mb dealer will not cover under warranty, cost for repair is $1800 (plus original repair). The symptoms are identical to investigation ea 13-003. Are similar parts involved? given the vast number of complaints here and online forums, an investigation should be done. There is no way this amount of fuel leaking is not a safety issue. This is literally a "ticking time bomb".

There is a strong gas smell coming from the vehicle especially after filling up the tank. It was inspected at fletcher jones Mercedes Benz dealer and the leak was found at the fuel tank filter, level sensor, and 2 seal rings. Due to the cost, I did not have the vehicle repaired at the dealer but at a local shop specializing in mb. Cost for the repair was $836.70. I am reporting this late for purposes of safety and trending.

A very stong gasoline smell in the garage after having car filled. The strong smell has been going on for sometime but didn't think too much about it. Last week a plumber came to my house for a leaky pipe situation and noticed the smell and said that was not normal and cou ld present a fire hazard! I immediately took the car to greenway Mercedes late on Tuesday, 9-29-15. I said I won't have to pay for this because it must be a defect. They said indeed I would have to pay. The diagnostic showed that it was the seals in the fuel sending unit, and I paid $1400 to be repaired. I told them I was going to file a complaint with you because I had researched and found other complaints filed for the same problem with you.

There is a very strong gas smell. It is overwhelming, lasts for days, and we need to park the car outside of the garage, as the smell is so intense it makes you feel sick. It just started happening about a week or two ago, and seems to be most obvious after getting fuel. I searched the internet and found that this seems to be a very common problem with a lot of mb owners having similar issues. Also, there seems to be a recent class action suit initiated by the NHTSA involving this problem. I'm concerned this could be a life threatening safety problem if an explosion occurs and the intense fumes seem likely to cause other health related problems.
