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.

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

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 $700.00. 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 $1500.00 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

When vehicle is refueled, strong odor of gasoline exists from rear passenger seat and rear exterior of vehicle. There's no visible fuel leak, strong fuel odor especially when inside the garage. No fuel odor when it's less than 3/4 full tank. The car has less than 30k miles when first notice the fuel odor.

When ever the vehicle is filled with gasoline, there is a fuel smell that persists for as much as several days after. There does not seem to be any visible fuel leaking, but the smell of fuel is there nonetheless.

Strong raw fuel odor was noticed after fill up on multiple occasions. Investigation found that both the fuel pump housing and the fuel sender housings were cracked allowing raw fuel to leak out. This is exactly the same as the e class recall. This recall needs to be extended to include the c class as well as this car has an identical failure mode. I found this issue was previously reported, and would like to second this noted issue. For many months have noticed strong fuel smell from left rear wheel well. Mb dealer confirms above similar diagnosis and approximately 1k repair cost, gas is leaking out and pooling on top of sender unit.
