2007 Mercedes Benz CLS550: gas smell in the cabin

Filed Sep 19, 2017 · Fuel system · 86,000 miles · FL

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.

Note that the vehicle on has 43,733 miles - cabin interior strong live fuel fumes - constant gas fumes on the inside of the car cabin. Note that the car was stationary at my residence parking. I did not know where were the fumes coming from at the time. Got a headache just for the moment I was trying to determined where were the fumes coming from. This is currently for all drivers and owners a very hazardous dangerous condition to all extremes, very high risk from ignition from static or electrical, due to wire hardness in the area. Vehicle was towed and took it to mercedes benz dealer and found the following: leakage in fuel system. Replaced fuel tank fuel tank drain/fill observed accident prevention regulation "12 wl08" fuel tank and fuel for storagebring observe accident prevention regulation "12 wl08" performed by mercedes-benz of new orleans. Fuel tank leaking in the interior was found / was drained & refilled and fuel tank replaced. This was cover under a new settlement with mercedes benz and the federal safety agency. I think that this should have been a recall when it relates to safety factors.

My husband and I purchased the 2007 cls550 about september 2015. We noticed when filling the vehicle with gas, we would have gas fumes in the vehicle specifically on the passenger side rear inside and outside. The fumes were light and would dissipate once the vehicle was driven to reduce the amount of gas in the tank to about three-quarters tank. Last week we filled the tank and the small is now stronger and has yet to dissipate although we have a quarter tank of gas remaining. I checked for any recalls on this since we have no knowledge of the vehicle having been in any accidents, but find we do not. This online search did not reveal any recalls for the gas fumes, but I noted there are multiple complaints about the same problem for this year, make and model of vehicle. Have any people died from this, any fires, accidents as a result? We have not yet, but will be taking our vehicle in for evaluation of the problem and would be able to provide documentation of the results in the future. Given the name, I am surprised mercedes is not stepping up here!

Every time I fill up my tank with gasoline, once I park in the garage, the garage is filled with strong gas fumes from my car. I checked for leaks under the car and found nothing. I have to raise the garage door to let the fumes out, due to getting lightheaded from the fumes. The fumes remain with the car for 7-10 days. This has been going on for the past four years. This problem is a danger to my family's health!!!! Surely, there is a recall on this problem! 2nd issue: I turned my car off and the fan kept running. I noticed that the fan was so loud that it sounded like it was about to blow up. Black smoke came from under the hood. I went on into the building to my meeting for an hour. When I came back outside, the fan was still going and still loud. This had never happened in the five years that I had the car. The car would not start. I had to call someone to boost it off to start. I then went to the shop to check to see if I had battery or starter problems. No problems found in either. This has happened twice since then. I am afraid that the car will catch fire with me in it or my family or friends. 3rd issue I was driving along and the dashboard read out in red to stop the car ..vehicle is too low... When stopped, I noticed that the passenger side of the car was low and the driver side is raised high. I have to sit there for a few minutes until the red lights went out. This happens often. 4th tire pressure light stays on. I took it to check on pressure, it was ok. I did not need new tires either. The yellow light stays on and this week the red light popped on and will not go off. 5th the check engine light stays on and mechanic can not find the problem. 6th steering system loud popping noise when I back up or turn steering wheel. It used to be random but now it is every time I drive the car.

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.
