Other Fuel System Tank Filling/charging Problems of Mercedes Benz E500

When filling the car with gasoline to a full tank, there is a strong smell of fuel that is very strong the next day. I have read in forums that this is a common problem with this model and that mb knows about this but is not doing anything about it. Is there a class action law suit on this matter? I bought this vehicle used. Am I protected under emissions laws or not?.

After filling the gas tank, I parked the car in my attached garage the next day the gas fumes were so strong inside my basement that I called my plumber, thinking I had a gas leak from the furnace. Then I went into my garage, and the gas smell was overwhelming. When I took the vehicle to Mercedes Benz, they did a diagnostic and determined the fuel sensor was bad, along with cracked inner tank module. I had to replace all the associated parts (cable harness, auxiliary pump, bracket, seal ring, etc. Parts: $710. 13 and labor: $496. 80 = 1206. 93. This issue should be reviewed as a manufacturer defect. I've had many automobiles, and never did I have this headache. And I certainly would not expect this from this car. Mercedes benze needs to own up to these defaults!!! additionally, my battery died at the same time - another parts: $284. 05, labor: $207. 00.

I am very worried what part of the fuel system has failed.

About a year ago I started noticing a strong gas smell after filling my tank.

I would like to know what resolution can be achieved with mb USA concerning this matter. I see that at class action lawsuit was submitted but don't see the outcome. That was in 2012.

This vehicle has a very strong gasoline smell after I fill the tank. This smell is concentrated on the driver side by the rear wheel. I do not have the money to repair or diagnose the vehicle. Although, mercedes has issued an extended warranty to 15 years unlimited miles for "covered fuel tank components".

I would like them to share specific information about this problem with me without charging diagnostic fee.

I have a 2006 E500 sedan. Just before the three year warranty expired, we notice a strong fuel smell in the car. We had a mercedes dealer, check it out and the serviceman said he found the problem with a seal on the fuel pump panel below the left rear seat. Said he had the problem fixed. This was the area of the problem but he didn't stop the leak. After the warranty expired we had the car serviced and the dealer found a bayonet fitting to a overflow cannister disconnected. The leak problem still persist and I have resorted to not filling the car up with gas. I have had to rip out the sound proofing blanket under the rear seat because of fuel odors. ( it got soaked. ) the seat foam got wet in the area just above the fuel access panel. Is there a seal (o-ring or otherwise in the fuel tank o cap in that access area) should I take the cap off and look for a burr on the tank? what torque value or how tight should this cap be screwed on the tank?.

I found out, this is a typical problem with the e class 2003-2008. I believe this is a safety issue and that mercedes should repair it ASAP. Thanks.

After filling up the tank, there would be very noticeable gas vapors especially in enclosed spaces like the garage. At half a tank, the gas smell goes away. I decided to take it to the mercedes dealer. The advisor asked me to sit down before he delivered the bad news. The gas tank has warped! this is a garage kept luxury car with only 42,000 miles. How can its gas tank warp I asked him and he said it has already happened to 8 other cars in the dealership. There was nothing I could do to prevent it from happening. Mercedes will not help any and it will cost $2,550 to change the tank to solve the problem. He said he can bring it down to $2,300 after discounts. I hope Mercedes Benz steps up to the plate to address this critical issue.

After completely filling up my fuel tank and drove away, I was overwhelmed by a strong fuel fumes. When I arrived at my residence, I found that some fuel had leaked onto the ground. I went online and found all over the internet that other owners of this class of vehicle have had similar problems related to the fuel sending units located under the back seat. When I looked under the seat the pad had fuel through to the foam under the seat. I allowed it to air out, and called mbz as I noticed that dot had filed a report in 04/2012 in regards to this problem in all w211 e class mercedes in conjunction with the recall for the e55 2008-020001. I called mbz and they stated that they couldn't do anything about it no matter how documented by other owners. We have a two year old that sits in a car seat, this is clearly unacceptable if a known issue on behalf of mercedes.

In June 2012 I was experiencing a strong gas odor upon filling my tank. Over the course of the next few months I visited 3 shops trying to find the issue with the odor. The first two claimed there was no leak in my tank and they were not sure of the problem. The last shop said there was no leak but could smell the odor in the vehicle. At this point it cost me, just less than $ 2000. , to fix issues related to the smell. # replaced cannister vent control solenoid. # aux sending unit # wiring harness fuel tank pressure sensor # wiring harness for vent control solenoid. I would not have fixed the problem, but the smell of fuel caused major concern, especially driving my children around. This did solve the problem. I read a newspaper article from the NHTSA today and it was talking about a leak in the tanks, as stated above, I do not believe this to be the case. Would I have recourse after the fact from mercedes from this obvious defect ? 2005 mercedes E500.

Reference NHTSA action #pe12001 last year I began to smell gasoline vapors when my mb E500 gas tank is 100% full. The smell finally goes away after using about 1/4 of the tank. The gasoline smell is so bad, I need to leave my garage door partially open to help remove the smell. Currently there are no signs of gasoline leaking on the ground, but the smell of gasoline is very strong both inside and outside the car. I've resolved myself to only filling up my tank to 75% full each time I re-fuel. I cannot find the leak or determine the gernal area around the tank which is leaking. This is a serious safety issue with the generation of gas vapors in a confimed space (inside the car or garage).

I noticed a strong smell of gasoline after filling the fuel tank. Smell is very strong both inside and outside the vehicle. This occurs every time I fill the tank. Sometimes fuel also leaks onto ground underneath the car. Took to mercedes dealer for diagnosis. They report that seals around 2 fuel tank covers have failed. The repair involves replacing the entire fuel tank. I have not made the repair due to high cost. I have learned that this is happening in many mercedes e class vehicles in same age range.
