In January, 2009, I purchased a certified used Mercedes Benz E350 from a Mercedes dealer in tuscaloosa, Alabama. At the time I purchased my vehicle it had approximately 40,000 miles on the odometer. In December, 2012, I began to notice the smell of fuel in the cabin of my car. The smell was overwhelming and increased over time. At the time I first noticed the fuel smell, my vehicle had approximately 90,000 miles on the odometer and the vehicle was no longer under warranty. I took the vehicle to my Mercedes dealer in georgetown, Texas, and was informed of the faulty gas seal and was very surprised when they informed me that I had to replace the seal, entire gas tank, and gas lines. To fix the problem, which was now a safety hazard as well as an environmental hazard to the occupants of my vehicle, I had to pay over $3,600 out of pocket to have the repair completed. The repair was completed in an afternoon and I have had no further issues. My complaint is that this is a known safety hazard with the make/model of this car and Mercedes refused to fix this known safety issue. Without fixing this problem, the car became unusable.

There is a strong smell of gasoline when vehicle is parked. Took it to the dealer and they indicated there is not a recall for this issue and the tank should be replaced. Researched this and found there are several complaints for this issue that have been lodged. The average Benz owner parks their car in the garage. The average homeowner has a gas water heater located in the garage. This is an open flame and gasoline connection which can result in an explosion.

After I filled up gas and parked for 2 days, I went back to the car and smelled gas odor from the outside and the inside of the car. I drove the car for 78 miles and still smell the gas while driving. I went back and parked, the smell still occurred. When I checked online, there was a lot of complaint about this issue ( fuel sending unit) on this car (Mercedes Benz wagon 4matic E 350. 2003-2009. ) the gas sending unit has leaked. I think this is a safety issue that NHTSA should open up the investigation and conduct a recall about this issue, because I have two children's of my own that sit in the backseat of our vehicle. I will take no chances to drive this vehicle and we still own a payment on it. If this issue is not being investigate, I will take it up to the next level ( national television). I hope this issue will resolve at this level immediately. Thank you [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

Strong gasoline odors inside and outside of the vehicle upon refueling the tank to full. The garage fumes with gas odors and the vapors can even be seen in the air. We are afraid to fill the tank and also very afraid if someone is nearby with a cigarette or fire..

After filling my tank, the smell of gasoline fumes, overtake the inside of the car and fumes vapors outside and around the vehicle until the gas gauge is reduced below full. The vapors and fumes are so bad that the garage and car emits the odors for weeks afterwards.

6/29/14 traveling when check engine light came on. Stopped and looked under hood, did not see anything out of the norm, drove it home. Drove a few days later to dealership. Found intake manifold faulty and cam adj maginet. Not repaired-$3000 quoted. Drove it home where it remains. Searches on internet shows this defect is under investigation. Also car rides rough; all four wheels are bent due to regular road wear and tear. Both these issues could have caused catastrophic consequences. I am not the first owner of this mb. Were mb aware of these defects and failed to inform me prior to purchasing the E350? the manufacturer needs to remedy these defects.

Filled gas in car up to full and have had a strong smell of gas inside and outside of my car. I always fill the car only up to a half of a tank but with the holiday weekend coming I filled all the way up since gas was cheaper. Never had this problem until I filled it all the way up. After looking this up on the internet I found this site and wanted to give my experience so hopefully this problem will be resolved by Mercedes Benz. Its sad that it will take someone dying or a major fire to have Mercedes actually look into this situation.

Strong fuel odor after filling up. The odor last until I drive the car for at least 40-50 miles. I have read on Benz world.org numerous reports of the same problem. Mercedes-Benz of austin reported..cause is left fuel lever sender unit pressure sensor leaking. With so many complaints and the enormous danger of having so much fuel accumulating around electrical components, I don't understand how a major disaster has not yet occurred. I have called Mercedes customer service managers in New Jersey on more that one occasion but no action has been taken. My last communication was April 23, 2013. Everyone I have talked to, associated with Mercedes Benz in some way, has tried to convince me that the problem isn't serious when I tell them Mercedes should be responsible for the cost of repairs. The repair cost was quoted at approximately $1000. After my investigation of the number of owners of Mercedes Benz cars with similar issues, a recall or major service bulletin is in order. This has to be brought to the attention of those who will do something about it. Please continue your investigation and let me know your findings. I have driven mb since 1966. The one I speak of is my 7th Mercedes. I believe they can do better for their customers.
