Hi I have 2007 mercedes cls550 79000 miles.I had the car for past 2 years are week ago after refiling the gas tank are strong gas smell appear inside the car and out side also.I was worry for my safety and I start reading about the same problems and current campaign and recall for mercedes e class w211 2003 to 2009 so I remove my rear passenger seat to locate the pump and the sending unit there was big puddle of raw gasoline inside the cabin around 200-300ml there was so much there the wires for the pump and sensors was under the fuel. I called the dealer they refuse to do recall for my car my car use the same gas tank and same pump and sending unit like e class from 2003 to 2008.. So if one part is defective(the gas tank) will be still defective if mercedes put in different model car.my car is not safe any more im scary to drive it any more .
2007 Mercedes Benz CLS550 fuel system complaints
Page 2 of 2: complaints 11 to 24 of 24, newest first, as owners wrote them.
Upon smelling gasoline when the auto in question was filled, we were directed my mercedes dealership on west sahara in the city of las vegas in the state of nevada. The owner replaced the gas cap. The auto in question continued to smell of gasoline off and on. In september of 2014 the auto displayed a signal at the engine needed to be looked at. The auto was taken back to mercedes on west sahara and the owner was informed that there was a fuel tank leak. Due to the quote of $3500 to fix the issue, the auto was taken to g&g auto and authorized mercedes repair shop in las vegas. The lead mechanic confirmed the fuel tank leak and showed the owner how the gas pooled on top of the tank which is just under the back seat. Obviously a huge danger. The owner of g&g autoshop informed the owner that this is a very common problem and alerted us to the documentation on the internet regarding class action law suits. The owner contacted mercedes head quarters in new york city and well as the general manger of the west sahara service center. The owner was told that the car was no longer under warranty and they would not repair the car unless paid. The car was ultimately repaired at g&g auto shop.
I started to notice a strong smell of gasoline inside and around my car. This occurred soon after filling up my gas tank. I looked around my car to see if I could detect any leaking, or puddling underneath my car but didn't notice many drips. The strength of the smell decreased as I drove and as the gas tank level decreased. The next time I filled up my gas tank the smell came back and was very strong. Anyone who rode in the car with me including my wife and our son, would comment on the smell. After doing some research I realized that many others have had this problem, and that there is even a class action suit open for this same type of defect in another year and model mercedes. I called to file a claim with mercedes USA, and they said that this is not something that they would cover the repairs on. I can't believe that mercedes USA wouldn't cover defect repairs for an issue many people have had, especially with the health and safety risks associated with gasoline leaking from the gas tank, as well as the gasoline fumes leaking into the cabin of the car. I hope there are enough people that voice their similar experience so that a government investigation can bring out the facts of this obvious defective issue. Long term effects of gasoline fume inhalation are suspect to cause cancer.
I've had this vehicle for years. Each time I fillup, there is a very intoxicating smell of fuel inside and outside the vehicle. I was reading up on it and seems to be a common problem. This is a true health hazard as you cannot breathe right because of the fumes. Not to mention the chances of it catching fire.
I filled my car up sunday and parked it in the garage, the following morning there was a strong fuel smell that permeated the garage and all around the car. I looked for leaks found none. The smell was coming from under the seat on the drivers side rear. I reviewed some online forums and noticed this seems to be a common occurence with these vehicles. This is very dangerous and a saftey hazard.
After filling up my car with gas I noticed a very strong smell of gas after I turned my car off. The garage smelled so bad I had to open both doors. I did not notice any leaking. I see some other cars like mine have the same problem. This is dangerous and a health issue. Mb so do a recall on this issue.
When I fill my vehicle up with gas, the fumes fill up my car and my garage. After I drive my car and the gas goes down to 3/4 a tank, the fumes reside. I can only fill my car up 3/4 of a way without the fumes entering my car. I took my car to the dealership and they removed the back seat and saw that the gas was filling up under the seat. They found a leak at the fuel gauge sending unit. The sending unit needs to be replaced.
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.
I had filled my car up with gas the night before I noticed the incident. The next day when I went inside of my vehicle it had spelled horribly of gas, so bad I was getting light headed from the fumes and had to keep the window's open to air out. But the smell has remained for a week now.. I located the source of the smell coming from the rear seat on the drivers side, I removed the rear seat cushion and it smells as if it was doused with fuel. Even with the seat removed the smell remains. I proceeded to look online about common issues for this problem, I noticed a recall on the fuel sender unit for previous years but not the 2007 model of my vehicle. I have seen many people complain of this exact issue for the 2007 model. I called the mercedes dealer about the issue and they say there is no recall for my model except for the camshaft selenoid. This is a highly important issue that should be looked into, I have my children in the car at times. I have made an appointment with the dealer to further look into my problem but I think this should be investigated and reported as a recall since others have the same issue.
Check engine light came on. Reads p0456 evap small leak detected. After filling gas tank full or anything over 3/4 full. Strong gas fumes smell inside and outside of car. Checked top of fuel pump under rear driver's seat. Fuel was puddled on top of this unit. (I have pictures if needed) replaced fuel pump seal ring and gas cap with new parts. Problem has came back with more check engine codes and strong gas smell/fumes inside car. I believe e-class 03-06 have same safety issues, and hope my 07 cls550 will be included in a possible recall, etc. As I believe the cars use same parts/platform. Refer to: the federal safety agency# pe12001.
Filled the gas tank. I drove 2 miles to my house, and parked the car in the garage. Fuel started leaking from the fuel tank directly behind the left rear wheel. The fuel fumes filled my house.
Strong smell of gas after filling up tank while parked in garage. Seems to be coming from rear driver side of vehicle. Please reference the federal safety agency action# pe12001.
When ii fill my gas tank I smell gas fumes in and around the vehicle. The smell is coming from the rear passenger seat on the drivers side. I had the vehicle checked by a mercedes mechanic who is a friend of mine and he said it is the fuel sending unit. He pulled out my seat and their was a puddle of gas on top of the unit. When I fill my tank to under 3/4 there is no smell. I have researched this issue and apparently there is an on going investigation by the federal safety agency regarding the e series mercedes which has this problem. The cls 550 is on the same platform as the e series. I have called the dealer and am playing phone tag with the service department. Please include the 2007 cls 550 in your investigation.
