When I fill the gas tank, there is a very steong smell of fuel inside and outside of the car. The smell ia there util at least half the tank is used. The same problem has been with "e" series. Mb issued a recall. However, the dealership tells me there is no recall for 2007 clk350 eventhough same parts are used to deliver the fuel.

When I fill my car up I can smell gas in my garage. Once I drive it for a while and it gets below a half tank or so I don't smell the gas anymore. I am worried that the gas smell in the garage made some fumes into my house and this is a safety issue. I see some models of mercedes have been recalled for this reason. I would like mercedes to recall and repair this at no charge to me. Apparently mercedes covers model year 2003 to 2009 on the e class in 2006 to 2011 on the cls class. I am having the exact same issue. *bf *tr

Strong smell of fuel from rear left side of vehicle after fill up. Fuel puddle found under rear passenger seat under fuel tank access panel. Left side fuel pump (fuel filter/sender) found cracked and leaking at the nipple to the outgoing gas line. This is a common failure for 10 year old e and c class mercedes and is part of a mercedes extended warranty program to correct this exact problem. However, mercedes tells me that my clk is not part of the warranty extension.

Gasoline fumes are inside and outside the vehichle after filling the tank. Mercedes agreed to warranty this issue for 15 years on the e-class and cls-class in ea 13-003. These components are the same on this model (clk). The investigation should be reopened and include all effected models.

I first thought someone had been stealing my gas until my car started to smell like gas. If I give someone a ride in my car, they make comments about the smell as soon as I start to drive. My coworkers have noticed the odor in when they pass by my car in the parking lot and the spots that it leaves on the ground. I took my car to the mechanic and he said my fuel pump is leaking on to the top of my fuel tank at an excessive rate and is not safe to drive. My car only has 84,000 miles so I did some research on recalls. Mercedes has extended warranties on several models from 2006-2009 but mine is not on the list. My car has the same problems as the other vehicles effected. What can I do next?

On december 9, 2016 I took my 2006 mercedes-benz clk350 to the dealership because of a strong odor of gasoline coming from the back seat area. The dealership found the fuel smell was coming from the left rear fuel sending unit leaking. Although I was aware of the extended warranty agreement between mercedes-benz and the federal safety agency covering leaking gas tank components on mercedes-benz cars, I was informed by the dealership that the agreement did not include gas tank leaks on my clk vehicle, despite the fact that the same gas tank leak was covered on other mercedes-benz vehicles. Thus, I had to pay for the expensive repair out of pocket. I am requesting that the federal safety agency amend your prior agreement with mercedes-benz to include additional models such as my 2006 clk 350 which have developed similar leaks in their fuel tank components.

Very strong gasoline smell coming from under the driver side rear seat especially after filling gas tank. Mercedes agreed to warranty this issue for 15 years on the e-class and cls-class. Why didn't mercedes and the federal safety agency include this model (clk) that has the same problem with the same components?
