After filling the gas tank over the three quarters(3/4) mark, there is an extreme of gas. No leaks are seen and a garage found no leaks. The odor is so bad/strong that the car can not be placed in the garage. The odor remain until the fuel level is at or below the three quarters level.

Car leaks fuel under the seat.

- El Paso, TX, USA

When I fill up with gas, the car salon fills up with the gas smell. The problem should be in the fuel pump or so. The smell is persistent in the garage. While driving, I did not notice. When the amount of gas in the fuel tank decreases, the smell goes away. I removed the back seat and so the gas residue over the pump.

For last three plus years, whenever gas tank is filled over the 3/4 full mark there is a heavy gas odor but I have not seen leaking gas. I only put in less than 9 gallons of gas at a time fearing an explosion in my garage where water heater is located.

One weekend we woke up in the morning to go wash, and as soon as we opened our doors to the vehicle a strong odor of gasoline came out of the vehicle. Inside of the vehicle and in the trunk it smelled a lot like gasoline, it's been like this now for about 4 days and the odor is still strong. It worries me because I have kids. We've been driving around with our windows slightly down, even afraid to turn on the heater or

Gas fumes outside car after refueling, parked in garage

- Deland, FL, USA

My 2007 Mercedes Benz C230 sport continually releases strong gasoline smell after each gas tank fill-up. This occurred consistently for the last four months. I've taken my car to the Mercedes Benz dealership local in my area only for them to say there is no reported recall or the cost to fix this matter is significantly costly. After researching this matter, I discovered there is a reasonable number of owners with a similar model and year that have reported the same serious risk of gasoline smell. Embedded is a link to the online site where these reportings are captured. M.carcomplaints.com/Mercedes-Benz/C230/2007/fuel_system/fuel_propulsion_system.shtml due to the nature and probable serious hazard of fumes exposure within the family household let alone other significant health risk, I'm requesting immediate assistance from the NHTSA to bring this matter to a resolve. According to public data, Mercedes Benz has recall numerous other vehicle models for the same defect which unfortunately did not include the 2007 C230 sport model. Please advise.

Fuel tank leaks gasoline into the back seat area from the fuel tank module if filled more than about 3/4 full. Fuel tank leak also causes P0442 code for leak in evap emissions control system. This is the same problem that resulted in the recall/warranty extension on 2003-09 E class and cls class Mercedes Benz, but mb refuses to accept responsibility for C class vehicles

After refueling car to full, car has a strong fuel smell. The smell persists if the car is over 3/4's full or greater. This has happened since I purchased this car but I couldn't determine where the smell was coming from until I took it to the mechanic and he said the fuel was spilling from the top of the fuel sending unit!!! he mentioned that this is a safety issue and that I need to check if this recalled already. I am now very mortified of this issue!!!

My 2007 Mercedes C230 smells of gas if I fill the tank more than half way. It only has 50,000 miles on

My check engine light stays on which Mercedes Benz stated its the magnetic stabilizer. Which was stated that a recall maybe coming. This causes a malfunction in having your emission to have a faulty reading. I have less than 120,000 on it. When I have taken to the dealership or service the light still came on. To my understanding a class action was taken against the company by this model was skipped over.

I purchased a 2007 Mercedes Benz C230 in 2006 from the Mercedes-Benz dealership and I have had it in the garage.I've only drove to church and that's it 700 miles is what's on my car.I've noticed about a year ago when I put gas it, you can smell it strong. I thought it was because of the type gas (supreme) what I've been using. I took my car to the dealership this morning to get a oil change when the service advisor told me that the car was leaking fuel.there are two rubber seals one goes on the driver side and the passenger side under the back seat. He told me that is going to cost $700. I asked him how is did that happen because I don't drive my car like that for something to go wrong with it. He states that it is very dangerous and driving the car could cause a fire or worst blow up.the gas is leaking and driving the car if you suddenly have to stop the gas would leak onto the exhaust pipe, if the pipe is hot there is a problem. I said well that has not come from me, I have taken care of my car since I bought it. The service advisor said sir, no this is not something that has been done by you.I said this should have been a recall because my car is brand new not by the year but by the mileage and fir something like this to be so dangerous.he agreed and said he will fix the problem.he put me in a rental from fri-mon and said he will call me when my car is fixed. I get home and later around 6pm he called me and said it was something else wrong from the effects of the gas leak and now want to charge me $1500 I told him I don't have that kind of money. And I need help with this because this is ridiculous I need to know if there is a recall or something.because I seen I'm not the only person who has this problem.I feel the dealership should be held responsible.the service advisor agreed with me that it seems to be a malfunction on their end. I need help! thank you
