I began smelling gas in the cab of the vehicle. After refueling, the vehicle was leaking gas from the right side in the driveway of my residence and the odor of gas in the cab began to increase. Merecedes personnel refused to acknowledge other issues and wanted to begin at their starting points regarding repairs. When this recall was addressed, I was informed it did not apply to my vehicle. After a lengthy elimination process, we learned the fuel pump flange had failed in this model as it has in other similar models. Merecedes at this point refused to extend a warranty consideration so I sought out an independent mechanic to repair it. Now Mercedes is refusing to reimburse the cost of the repairs.

When I fill up the car with gas, my car smells like gas inside and out until it reaches about a half a tank. This is very dangerous and I've read that several other Mercedes are having the same issue. I've contact Mercedes but they say it's not on a recall list.

About 5 months ago I smelled a strong odor of gas fumes omitting from my car while I was driving on the freeway. I live in southern California where the weather gets extremely hot. I brought my car in to get checked out at a local mechanic shop on 12/23/2016 and it turns out that the fuel tank was cracked and leaking fuel. I looked on the NHTSA database and found a recall reported on 12/03/2012 regarding a fuel filter leak as mentioned below. NHTSA campaign number: 12V557000 manufacturer Mercedes-Benz usa, llc. Components fuel system, gasoline summary Mercedes-Benz is recalling certain model year 2011-2012 S400, S550, S550 4matic, S63 amg, C300, C300 4matic, E350, glk350, glk350 4matic, CL550 4matic, and CL63 amg vehicles I manufactured from April 18, 2011, through July 12, 2011. Due to an irregularity stemming from the molding process of the fuel filter flange, the fuel filter flange may crack when operated in high temperatures. Although the recall was specifically for Mercedes Benz C300 manufactured in 2011, I believed it should also extend to the previous year; 2010. Im reporting this to see if any other cars had the same exact issue as what was described above. I believe this is a definite fire risk especially to those living in very hot locations such as southern California. I would like to know if the recall covers my car and if so I would like to get reimbursed for the services I paid to the mechanic shop. Thank you.

I had to pay for a fuel filter leak due to a crack of the fuel filter flange and was told this was not a recall on my vehicle, but when I was looking at recalls for my year and model I came across NHTSA campaign number-12V557000 with a recall on merceded-Benz C300 4 matic model year 2011-2012 for fuel leak due to cracked flange. I asked the dealership about it even though that is exactly what had to be replaced and said it did not affect my vehicle, I called Mercedes Benz at the number provided in the remedy section of the announcement and was told it was not my vehicle, please advise what I should do next, thank you

I filled my gas tank up Friday evening, went home and parked my vehicle in the garage. The next morning there was a strong smell of gasoline coming from the car. I took it to the Mercedes dealer and they said the seal and cap under the passenger back seat needed to be replaced. They wanted to charge $434. Not only is this dangerous it should not be the consumers responsibility when the manufacturer provided faulty material.
