There is a fuel leaking into the backseat of my 2007 mercedes benz cls 550 I began noticing the smell in my car a few months ago and I finally decided to remove the back seat, under the back seat lies the fuel tank and a fuel filter module which is leaking and creating a small pool of fuel and a fuel scent in my car. Incidentally mercedes had a recall on the mercedes benz 2006 cls (voluntary emissions recall campaign #2008-020001) my car is a mercedes benz 2007 cls with the exact same problem. I would like to file this complaint and ask that you help me in getting mercedes benz to take responsibility for this faulty fuel filter module and initiate a recall to repair this problem. This problem has been documented extensively on many mercedes benz forums http://www.mbca.org/forum/gas-leak-sending-unit this issue creates an immediate hazard to me, my family and other drivers. I ask that you take quick action in contacting mercedes benz demanding they make amends to this issue before someone gets seriously injured.

When I fill up my car with gas there is a strong gas odor around the left back seat on the interior and around the left rear wheel on the outside. After further investigation I found gas leaking around the left sending unit / pump. This is a serious design flaw as the sending unit / pump is made of plastic and servers a structural member to suspend the unit in place. The presence of gas fumes in the interior is a fire and human health hazard and the gas fumes on the outside of the car is at minimum a fire hazard. This appears to be a common defect on mercedes cls and e-class between 2004 - 2008. Thanks for your assistance in this matter.
