VIA REGULAR MAIL AND ONLINE SUBMISSION RE: VIN # [redacted] - Mercedes Benz 2007 E 63 Dear NHTSA - We would like to bring to your attention the failure of the Fort Lauderdale Mercedes Benz dealership to properly honor the repair and replacement of parts and labor covered under a recall for Fuel Tank Components for MODEL 211 (E-Class) years 2003-2009. A copy of the Recall notice which provided for an extension of the Recall thru 01/31/2021 is attached. Also attached please find a recent repair invoice for the respective repairs which should have been repaired under this recall. Mercedes Benz undertook a "partial" repair of the parts covered under this recall and at the time of that repair failed to properly repair all of the parts related to this issue/recall. …
My 2007 Mercedes-Benz E63 AMG, which has developed a fuel system defect resulting in a leak. This issue poses a significant safety risk, including the potential for fire and explosion, and is directly related to a known defect that Mercedes-Benz USA has previously acknowledged through an extended warranty campaign.Safety Risk: Fuel system leaks pose an imminent danger, including the potential for fire and explosion, to vehicle occupants and others on the road. Manufacturer Acknowledgment: The warranty extension campaign underscores Mercedes-Benz's recognition of this defect as a manufacturing issue, Repeat Occurrence: Having experienced this defect in my previous 2005 E500 4MATIC and now my 2007 E63 AMG, it is evident this issue is systemic and not isolated.Ethical and Legal Responsibility: Safety defects do not have an expiration date. …
I just purchased the vehicle used from a dealership. I drove the vehicle 2000 miles home and I parked the car in my garage. I filled the gas tank prior to parking in my garage. The next morning I entered my garage and smelled a strong odor of gasoline. I could see gas underneath my car by the rear drivers side wheel and the odor of gasoline was so strong my eyes were watering and I couldn't breath well. I opened the garage door and moved the car outside(pushed it outside to avoid an explosion). The odor of gasoline is very strong by the driver's side rear compartment. I keep the fuel tank at half full or less to minimize the gasoline vaporous smell. I bought the car in chicago and drove it home to washington state.
I filled up the gas, took a short drive home, and parked in the garage. Next day, there is a strong gasoline smell in the garage as well as inside the car. This happened whenever I filled up the gas since then.
I reported to my independent mechanic a strong fuel smell when filling the vehicle full and parking it. Upon further investigation, my mechanic discovered a fuel leak from the drivers side of the tank onto the left exhaust which of course can create a fire hazard. I immediately contacted my local mb dealership and spent days trying to get in touch with the service manager. Finally after contacting the mb central region office, I left a vm and was contacted by the service manager I had been trying to get in touch with. As of today 4/8/13, I took the vehicle in for inspection. They told me that the drivers side fuel sending unit/pump is leaking and would need to be replaced. I asked if the car was safe to drive, they replied no, but happily sent me on my way anyhow. This problem lines up with every other complaint about the my03-09 w211's that exhibit this problem. …
I purchased this car late July 2012 and when I went to pick it up I noticed a slight smell of gas from the left rear of car but, didn't think much of it as it was a new to me vehicle, just thought it was freshly filled up. The next time I filled up I noticed that the car smelled both inside the car and outside the car. As a new owner of a newer mb I joined mbworld form and searched this problem with e55 and E63 and found that it is a common problem for the w211 cars. Also, it seems the solution is not as obvious as one would think. On nov 14, 20012 I took it to cal star motors in glendale ca (a Mercedes dealer) for repair, they told me that the cause of the problem is the seal between the sending unit and the gas tank. They replaced this part and I drove the car home as I needed to bring in car with half a tank for repair I did not notice any issue. …
Normal fill up of gas tank causes fuel to leak out of top of sending unit. The seam just below the electrical connection powering the units motor seems to be weakly and/or improperly joined, allowing raw gas to leak out and pool into a small compartment under the drivers side rear seat. When I purchased car used 14 months ago, I noticed extreme gas smell after 1st night in the garage. I immediatly took vehicle back to dealer where they replaced sending unit under 30 day warrenty. Now only 14months later after a normal fill up at a gas station and then driving home, I noticed a very strong gas smell as I entered the garage the next morning. I have found that I am not the only one with this issue. Online research lead me to information that gave me the details neccesary to locate and remove the access panel under the drivers side rear seat. …
Similar to the complaints filed by Mercedes Benz w211 members owning 2003 - 2006 e55 AMG's, my 2007 w211 E63 AMG is experiencing fuel leaking from the fuel sender/pump assembly unit. I noticed a distinct gas odor in my garage the morning after I filled up with gas. I checked the fuel sender/pump assembly area as is stated in many forums where owners are complaining about this commonly occurring issue. There was fuel puddled in the cup of the assembly. I replaced the seal hoping that it would correct the issue but it did not. I filled up again with fuel on Tuesday, August 14 and within minutes there was fuel puddled again in the assembly area and a distinct fuel smell on the outside of the vehicle.
Tl* the contact owns a 2007 Mercedes Benz E63. The contact stated that after refueling and then parking the vehicle, he noticed a large gasoline fuel leak. The vehicle was taken to the dealer where they advised that the fuel sending unit malfunctioned, causing the fuel leak. The fuel sending unit was repaired however, the failure recurred one year later. The manufacturer was not contacted. The failure mileage was approximately 54,000. The current mileage was approximately 74,000. Updated 04/30/13 the consumer stated the fuel did not leak onto the ground. It was contained within the cavity/space surrounding the fuel sending unit.
Car began smelling of raw fuel after being filled up. Found that the fuel level sending unit was leaking fuel out of the top of the fuel tank. A puddle of fuel was visible on top of the sending unit and was leaking onto the ground. This posed a significant fire risk and the car was moved outside. I have contacted mbusa and they have offered no help, saying this isn't a known issue. After researching the issue I have found it is widespread and affects multiple models. We can no longer fill the fuel tank without having a puddle of fuel left under the car.
