Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

I took my vehicle to my regular independent Mercedes-Benz mechanic because there was strong gasoline smell inside the passenger area of the car and I noticed there was a small puddle of gasoline under the car whenever I filled up my tank. My mechanic inspected the car and found gasoline pooled up in the recess where the fuel pump attached to the fuel tank. He informed me that the leaking fuel posed a serious safety hazard and could possibly lead to a fire, or even a possible explosion should I park inside my garage. He said the water heater Pilot light or any other source of spark could ignite the fumes and burn my house down. In addition, he stated he had seen this same problem many times before and that Mercedes-Benz has been aware of the problem for many years but refuses to accept that they had installed a defective part in the thousands of vehicles of this model they produced. It would simply be too expensive to remedy. If I wanted it repaired it would be at my own expense since Mercedes-Benz is accepting no responsibility for this known issue.the leak has caused my vehicle to be unsafe to operate.

After filling the tank at a gas station, I went home (5 miles) and parked the vehicle in the driveway. When went back out to driveway about15 minutes later noticed a bad gas smell around the vehicle. Smell was worst under left rear door. Looked under vehicle and could see smell gas in the tray below the gas tank. I pulled the tray down slightly and a few drop of gas dripped out. I could feel gas in the tray with my fingers. I think gas tank is leaking from top of tank. Glad I didn't park in the garage.

When we fill up the car with gas we have a residual smell of gasoline upon return to our garage. This does not happen if we do not fill it up fully. We thought we must have a leak somewhere, but are not sure and although we discussed it with our mechanic, we have had no resolution to date.

Mercedes E320 2004 smells like gasoline in my garage, especially left side (though fuel door on right). I took to my mechanic who told me gasoline puddling on top of tank and I needed fuel pump, fuel pump seals left and right, fuel pump bracket and cable harness. Spent $625 to fix. I saw in newspaper yesterday (March 20, 2013) NHTSA has received 533 complaints regarding fuel leaks regarding Mercedes. I think there is something wrong.

Car started reading SRS airbag malfunction (still needs to be repaired) car is sometimes unable to read how much gas is in the vehicle. Car couldn't pass emissions. Check engine light on.the car smells of a strong gas odor. Unable to park the car in the garage because of the strong smell. Every time the tank is filled with gas the car presents a strong gas odor until it gets below half a tank. Mercedes wanted to charge me $4000 to have it fix so I took my car to a foreign car repair shop who charge me $1,300. Problem fixed, however I recently took my car to Mercedes because my check engine light came back on so they charged me $2,100 to fix that along with regular maintenance.

A strong smell of fuel was present after starting the vehicle in my driveway. Checked the vehicle for leaks and found none. The following day, the same occurred in my driveway but fuel seeped from the rear of the vehicle when I backed up. Took the car to my Mercedes mechanic who inspected the vehicle and replaced the fuel pump and lines located above the fuel tank.

  • 74,000 miles
We recently purchased a 2004 E320 with 71000 miles in August 2012. Last week, now with 74000 miles, we noticed a strong gas smell in the car. After doing some research online and in Mercedes forums we concluded that it may be the fuel unit. We pulled the rear seat and took off the cap and noticed a pool of gas, right under where our 2 yr olds car seat is, about 2 cups that I took out by soaking numerous papertowels.I also took pictures just in case it may be needed it the future. Throughout all my searches online I've noticed that this problem is very common in the E class and numerous people have tried to resolve it through Mercedes but nothing has been done. A recall was issued for the E55 trim but no other, which makes us wonder why. We will not drive it until it gets fixed (as of today it has not been ) because we feel it is not safe for our family to have a pool of gas with electrical wires right beneath our seats.

E320 6-cyl

  • 65,523 miles
My 2004 Mercedes Benz E-320 began emitting a strong odor of gasoline in 2010 and was taken to the local dealership (schumacher Mercedes in scottsdale, Arizona) for inspection when it was determined that there was a leak in the fuel tank and that it needed to be replaced along with the left sender pressure sensor and tank fittings. The vehicle had approximately 60,000 miles at this time and was outside of the initial warranty so the $2,500 repair was undertaken. Approximately 2 years later and 40,000 miles later, the same symptoms returned and the vehicle was taken back to the same dealership for inspection. It was determined once again that the same problem was occurring and the fuel level sensors were leaking fuel and needed to be replaced again. The cost for this repair was estimated to be $1,200 and this time the repair was rejected. The service advisor at the dealership claimed this is a common problem with these cars and there was nothing they could do about it. The vehicle had always been maintained by the dealership since the beginning and apparently there have been no recalls issued that we were aware of for these malfunctions and defects. I have contacted Mercedes corporate office and they opened up an investigation only to determine that the dealership acknowledged the problem with the vehicles but neither party was willing to accept responsibility for the defect and no additional assistance would be available or commissioned for me. This is a major safety issue and should not be considered a common issue or routine maintenance for any car, let alone a Mercedes Benz. If something does not get rectified with this epidemic malfunction of these vehicles, it could lead to a major accident or even death.
