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.

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!!!

Strong fuel odor after filling up my car. After 2 days odor was still there. Took to dealership to be checked and was told that the fuel sending units need to be replaced and will cost $1130.00.. I have very low mileage on my car 48,336.. This is a huge safety and environmental issue. Very unhealthy to breathe in fuel vapors and bad for the atmosphere. This is exactly the same as the "e" class recall. Why wasnt the "c" class included. Please make this a recall on the "c" class.

I believe this is related to the federal safety agency action number ea13003. There appear to be complaints by others as well for the 2007 c230 regarding this issue. Basically, whenever I fill up my tank, I smell gas outside of the car, not inside. The smell seems to be strongest at the right side passenger mirror door area near the hood of the car. Then after a gallon or two has been used, the smell goes away. It took me a while to reproduce and identify this pattern because I don't refill my tank all that often (I drive about 2k miles a year.) I first started noticing this smell around june 2014 after I had my spark plugs replaced due to the recommended age limits. At first I thought it was due to that. So I took my car to the dealership and they identified a leak after I described my problem. I have lost all confidence in mercedes due to a number of issues on my low mileage car, that I started researching this in google and discovered other people describing the same problem of fuel odor when the tank is full. This leak also corroborates what I have noticed on the fuel gauge; the fuel gauge drops from full to 3/4 full after driving about about 25 miles or so. That can't be right because 25 miles or so is not even 2 gallons of fuel, and the tank holds about 13 gallons, unless there is a leak. Please see if the problem which affected the e class models from the same time period is affecting the c class model. Thank you.

Tl* the contact owns a 2007 mercedes benz c230. The contact smelled fuel near the rear seat in the vehicle. The vehicle was taken to a dealer, who diagnosed that the fuel sending unit needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 123,000.

This car pulls to the right and nearly changed lanes and almost hit another car during a split second of looking at the gas gauge and not down the road. I took the car into mzb with the complaint. They said it was my driving habit. Later they said it was the curve of the road. Still later they said it was the tires not inflated. As I continued to ask for help on this issue and several times bringing it back to the dealer they finally said that a mzb rep will go with me on a test ride. During the test ride I stated that at any moment you ask I will let go of the steering wheel and the car will turn to the right. After several of these demonstrations to him he then held the wheel himself and felt the pull. He agreed with me that there was a problem. Upon returning to the dealership they met in a meeting without me and began to do this and that with the car on the rack. I asked what are you doing? They told me minor adjustments. Later the car was released to me and in fact the problem was better however not corrected. This car has a terrible problem and does not run down the road straight since I bought it new. I drive it now the way it is because I am tired of mzb and their tactics. The car was returned to mzb 12 times in the first year of ownership for repairs. Please help if possible.

I've had this problem several times where I put in the car key to start the car, yes it starts up but the gas gauge ,speedometer, and the rest on the dash go to all the way down and don't move, then my check engine light turns on. Sometimes the car doesn't start as well . I've gone to the dealership to buy a new key thinking it was the key but still the same problem. I saw that most of the c class has been recalled for the same issues I'm having but they didn't recall the c230. I believe you guys should do better investigation next time because I don't think I should have to pay to repair something that came defective. Also I've noticed that the 2006 c class also has a recall for the airbag which I've has the esn or esp letters popping up on ny dashboard stating something about the airbag yet my vehicle isn't eligible for that recall as well and I ask myself why? If they same problems I'm having are exactly the same I'm having with the recalled vehicle.
