Several times I've filled my gas tank I got a strong smell of gas before entering my vehicle. I had then made sure not to fill the tank up due to this leakage. I believe its very dangerous. The smell doesn't go away until I drive the car for several days.

We just bought this car. After I filled it up, there is strong gasoline smell in the garage. Parked the car outside and it still has smell. Is this a common problem with Mercedes Benz C280" upon further research, there was extended warranty from Mercedes to cover E class and cls class fuel odor only. What about the C class cars" don't believe this is the way the car should be performing. By the way, the car is 2007 with 102K miles. I believe Mercedes should also cover C class for the same problem,

Very strong odor of gasoline fills the garage and house when the vehicle is parked inside after fueling to full tank. The gasoline odor is so strong that I feel it is unsafe to park the vehicle in the garage because of the fumes, and the potential for fire

Strong gasoline ordor coming from left rear wheel well every time the car is refueled. The strong ordor lingers on for 2-3days filling the garage and house with fule ordor. Seems to be the same problem as E class, which is under an extended warranty for the fuel ordor issue. Mb service rep said that C class vehicles are not covered by the extended warranty and owners are responsible for the cost of repair.

76000 ml nice and clean but, all of the sudden strong smell of the gasoline inside. When did my research online found a lot of similar complaints with same symptoms as what was investigated on report# VRTC-dcd-3206 by NHTSA. Upon filling up the gas tank to full, gas leaks from sanding unit under rear passenger seat. Can not understand why same recall is not applicable to the C-class mb, makes no sense to me as to the others unhappy mb owners. My next car is Lexus, done with

L/H fuel unit fuel sender O rings fuel sender lock rings all for the low cost of $1,095.84 for now we are not filling tank. I've read on line this is a problem with mb a recall should be done.

- Rockville, MD, USA

This vehicle shows same symptoms as what was investigated on report# VRTC-dcd-3206 by NHTSA. Upon filling up the gas tank to full, gas leaks from sanding unit under rear passenger seat. Few times the gas has made its way out and dripped from rear left wheel well. Reached out to mb usa and was told the recall was only in E-class and they will not extend it to C-class. I see this as a poor product design as the car only has under 14,000 miles. It's both health and environmental hazard.

After my car was serviced on January 11, 2013, I noticed a strong smell of gasoline every time I filled my gas tank. The smell was evident inside my car and in the garage and even in my house. After the third filling of my gas tank and an ever-worsening smell, I took the car back to the dealer to ascertain and fix the problem (March 15, 2013). They found fuel leaking from the driver's side fuel level sensor and replaced it for $1200. I saw an article in the los angeles times on March 20, 2013, that federal safety regulators are investigating this problem in the E-class, and you should know it is occurring in the 2007 C-class, also. I can still detect an odor, though not as strong, after I fill the gas tank.

After filling up the gas tank I noticed a strong odor of gasoline in the cabin while at a stoplight. Upon returning home, the car was shut off and could smell the gasoline on the drivers side exterior. After the car was sitting in the driveway for roughly 3 hours, we noticed a "pool" of gasoline on the driveway surface. Contact with Mercedes-Benz of waco revealed that the technicians there have done many tank/sending unit replacements as these are "known to fail and being out of warranty these repairs would cost no less than $1800 out of pocket and will likely not fix the problem. We suggest you research recall status and complaints made before doing a possible temporary fix." We are concerned with driving the vehicle in this condition and are extremely upset with the lack of safety recall for this problem.

- Temple, TX, USA

Strong smell of gasoline inside and outside of the Mercedes C280 2007 when it's filled up, or filled past the second notch on the fuel meter. Inspection of the fuel tank underneath the rear seats reveals a visible fuel leak on the left sending unit a the top of the fuel tank. Google search results suggest this leakage may be related to a March, 2008 emissions recall conducted by Mercedes Benz (emissions recall campaign # 2008-020001) which involved potential cracking of the fuel filter module in vehicles exposed to high ambient temperatures. I contacted two different mechanics who own Mercedes repair shops, and they both confirmed these are common problems with Mercedes vehicles of different models and years. Fixing is very expensive (close to $800). Meanwhile, the leaked fuel could ignite a fire, explosion, and, to the least extent, is sending fuel fume out to the environment. Please investigate.
