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.

Began to notice a significant fuel smell outside the rear tire on the driver's side of the vehicle. It is so strong that when it is enclosed in the garage, we are afraid a Pilot light could ignite a fire.

After filling car with gas there is a strong gasoline smell coming from the car. Goes away after driving and some of the gas is used out of the tank. Cannot find any gas leaking on the ground around the vehicle and I do not 'top off' the tank. I am no longer parking the car in the garage as I am concerned about an explosion as there is a gas water heater in the garage. Somewhere in the system this gas is leaking....and it's not coming out on the ground!!! scary

After refueling the car to a full tank of gas, I began to smell a strong odor of gasoline in and around the vehicle parked in my garage. This happened after repeated fill ups. I took the car to the mercedesbenz dealership and was told the problem was bad purge valve which was replaced for approximately $300. The problem has continued and I am now being told by the dealer that the fuel tank, lines and other components need replacing for estimated $3500. I was told by the dealership service manager that this was due to the age of the car and that there had been no recalls or prior complaints, to his knowledge, of this similar complaint. I have now learned that the NHTSA has been investigating this same problem in this year and model car for over 2 years and there is a class action lawsuit filed against Mercedes Benz for this same issue.

Noticed strong fuel smell in cabin after filling tank - took car to dealer and was quoted over $700 to replace fuel level sender and seals. Problem causes unsafe level of flammable and toxic gasoline vapor to build up in car due to evaporation of pool of leaked fuel on top of tank (located under rear seat). Appears to be common on '03 to '09 W211 body style, but mb offers no help unless car was sold in states requiring pzev certification.

After fueling the car, strong odor of gasoline stays until tank is 3/4 or less full. The problem is consistent with every fill up. Replaces gas cap but it was not it. Seems like it is commonly occurring problem with leaking gas seals or tanks.

About a year ago (May 2013) we noticed gas smell in the compartment of the car. Initially it was sporadic. We thought it was from outside of the car or may be under the car, or gas tank cap was not tightened properly. After I took my car to Mercedes Benz dealership on 9/6/13, I found out that the smell was not from either of the above scenarios. It was indeed from inside the cabin and the Mercedes Benz technician told me that it was from fuel leakage under the back seat and it would cost $1380 to fix it. Additionally he said that he had seen numerous cases like mine, and some were so bad that they would not be able to drive it in, and had to tow the car in. Because of the high cost in addition to the other repairs that I had to do worth $1,200, I decided to delay this repair. Now we can not even drive the car because of the intense smell and will cost me probably more that $1,380 to fix it. I believe strongly that this is a manufacturer defect and should be fixed and paid for by Mercedes Benz.
