2007 Mercedes-Benz CLS-Class owner complaints

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 tha

Tl* the contact owns a 2007 Mercedes benz cls550. After refueling the vehicle, there was a strong odor of fuel present inside the cabin of the vehicle. In addition, the vehicle failed to start on several occasions. The contact noticed that there was fuel leaking from under the driver side of the vehicle. The vehicle was taken to an independent mechanic where it was diagnosed that the left fuel level sensor failed and needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was unknown.

The fuel tank has a leak from a defect in the plastic, and my local Mercedes dealership is unwilling to honor the Warranty Coverage Extension that covered fuel tank components to replace the fuel tank.

I am referencing action # pe12001. After each of my last two fuel filllings, the car is emitting a very strong smell of gasoline from the back seat & trunk compartment. I park my car in my garage and the smell is strong enough that I can smell it in my home. I am extremely fearful that there will be a fire. I do not desire to park my car outside, but I believe the car is unsafe to keep in garage. I have lost confidence in my car fearing that even driving it around town could pose a danger to me and my passengers.

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

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. *tr

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 NHTSA 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. *tr

Tl* the contact owns a 2007 Mercedes benz cls550. The contact stated that strong fuel fumes were present inside the vehicle. The vehicle was taken to an independent mechanic, but a leak could not be detected. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 51,000.

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-lea

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

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. *tr

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

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. *tr

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: NHTSA# pe12001. *tr

Fuel smell suspension drivers seat tearing brakes

I was driving and the car sensor popped and it said stop vehicle too low... When stopped, I saw that the right passenger side looked like it was dropped right over the wheel... The rest of the car was raised.. I tried everything the manual said, nothing work.. I can hear a compressor working.. I have seen many a few blogs on the internet with people complaining about same issue. My vehicle has 47,000 miles. And it seems to be right when the problem occurs. *tr

Driving highway speeds and suddenly vehicle jerked and losses all power. Engine revs but doesn't move. This can be a very dangerous situation. Transmission went into 'limp' mode and check engine light lit. Many other Mercedes owners reporting same problem with the 722.9 transmission valvebody, conductor plate, and/or TCM. This should be investigated as countless other people are reporting this same issue for several years now.

Catastrophic failure with sudden loss of power and inability to proceed at more than 20 MPH. It has now recurred twice and vehicle flatbedded to agency. Has been in shop for six days with no repair. Service manager denies that this is the second failure because his diagnostics were unable to determine the problem the first time. *tr

I have a 2007 Mercedes cls 550. My headrest have deployed for some reason on at least four separate occasions. When the headrest deploys it hits me in the back of the head. It has happened 2x while driving on the freeway and 2x while backing up. The dealership has repaired the headrest on at least four separate occasions. Including keeping the vehicle for almost a month and half. That repair was just a few months ago. Last week while driving on the fwy, the headrest deployed again for no reason and struck me in the back of the head. I believe this is a defect and a safety concern. In addition, my vehicle steering wheel started peeling a year ago. This paint comes off on my hands and can end up in my eyes, nose and mouth. I am concerned about the contents of the paint. Mercedes
