2012 Mercedes-Benz E-Class FUEL/PROPULSION SYSTEM

I have a 2012 E350 with less than 95000 miles and I see these vehicles were recalled in the past for their fuel tank manufacturer malfunction but my VIN number was not included. This car went numerous times to the mechanics and the fuel components fixed but it still leak gas and smells even when I do not drive the car. I spent over $15000 on this matter. This is now becoming a safety issue for me and my neighbors. I don't know what to do. Here is what happened. All began February 2023, I towed the car to an approved MB mechanics who said fixed the car. 9 month later, I brought the car back for the same issue. Strong fuel smell. The attachments for repairs will show the work done. Some repeated and recharged to me. The following year April 2024, I woke up one day with a fas leak all over my drive way and a strong smell of gas. I had the car towed for a repair cost of $7754 total. I am constantly having the same problem with the car and wanted to alert here to bring Mercedes Benz awareness to their faulty parts putting consumer lives at risk.

Recently, I have noticed a strong gas smell emanating from the rear driver’s side of the vehicle. Upon further research, I discovered that there was an open recall affecting Mercedes E-Class vehicles of the same year for a similar issue. However,my vehicle’s VIN is not included in this recall. Given that my vehicle is experiencing the same problem described in the recall, I am concerned about the safety implications and believe this matter warrants immediate attention. I would like clarification on why my vehicle is excluded from the recall despite exhibiting the same issue. Additionally, I would like to know if I am expected to pay out of pocket for repairs related to what appears to be a manufacturing defect acknowledged by Mercedes-Benz for other vehicles of the same year and model. I kindly request that this matter be escalated for review, and I look forward to your prompt response. My goal is to ensure the safety of my vehicle without incurring unfair expenses for a known issue.

The top of the fuel pump is leaking (driver rear side, under the seat) and the leaking can be seen outside of the car as a moisture on the underside of the car. The fuel filter side (passenger side, under the seat) has a small amount of fuel moisture. The current mileage on car is 76,620 miles.

The incident was not the vehicle persa but passengers riding in back seat experienced nausea and headaches. Found gas fumes emitting from vehicle. As time progressed fumes got worse and fuel mileage performance worsened. Gas consumption was extremely bad. Car was taken in for oil change and absolutely no gas leaks were found and technician showed me the under carriage of car. Nothing showing on the OBD. Afraid car will catch fire. Not driving as of today.

There is a strong smell of gas inside and outside of the vehicle. Gas is being consumed at a faster rate than usual. No warning lights have come on inside the care. The smell is strong and is affecting all passengers (headaches, nausea) including children and toddlers.

I smell gas all the time inside and outside the car.

While driving the vehicle, noticed a smell of fuel inside the car. Parked the car in my garage and the next morning, noted a heavy smell of fuel in the garage. After some research, discovered a recall on the fuel filters for 2011-2012 Mercedes E350 for the fuel fillers. Took car to dealership and they stated the recall was not associated with my VIN despite my car being the exacted year, make, and model for the recall. I removed the back seat to view the fuel filter and saw fuel puddled inside the car, on top of the fuel filter, under the left side of the rear seat. The risk is twofold. Spark ignited the gas in the vehicle out a spiral ignited the fumes smelled in my garage.

Fuel leaking from rear passanger side tire area. Took vehicle to dealer. Dealer identified faulty fuel tank as source of fuel. This problem has been reported in other Mercedes classes, including a manufacturers recall. My vehicle is 10 years old with only 71,000 miles. Dealer wants over $7,500 to repair. This issue has occured in other Mercedes classes. This is a safety issue as driving with a leaking fiel tank can cause a fire and explosion. Please expedite this issue. Thanks

Everytime I fill up gas tank and park car in garage. Strong gas smell fumes.

I sent NHTSA a report earlier -#485386-- A mercedes recall=#12V557000- for this vehicle was issued -- on cars manufactured from 4/18/11 to 7/12/11. My auto was manufactured on 7/11. There is no exact date listed. The past few weeks I did smell gas outside of the car. I spoke to the dealer who told me it was not a recalled car. I went ahead and went to a repair Mercedes shop to investigated the problem and found that the gas filter was leaking as indicated in the recall. Mercedes needs to expand the recall dates since it is obvious the dates are incorrect. I went ahead and took pictures of the leak and sent it to Mercedes customer service. Again response from them was the car was not on the recall. I also want Mercedes to pay me $478.70 for the repair. Pictures of the filter/leak was also sent to them and you.

I noticed the strong smell of fuel around the rear of the car especially around the back. Upon inspection I noticed that the corner of the tank on the driver's side was wet with fuel. I took it to my mechanic who on inspecting the car reported that the pump outlet on the driver's side pump (which is accessed from the interior under the back seat) was spraying fuel up against the underside of the car against the rear seat and also noticed that the second pump on the passenger side on top of the tank was also seeping fuel. To have fuel leaking anywhere is dangerous, but to have it happening under the rear seat where my children sit is extremely dangerous. I checked for a recall for this problem with Mercedes but didn't find one on their site. I called them at their corporate HQ and they claimed not having a complaint like this before and didn't want to accept any responsibility for the faulty part/s. This is in need of immediate attention by Mercedes Benz before someone loses their lives because of MB ignoring this serious problem. [XXX]... Phone [XXX] email [XXX] Car fills with strong fuel vapors with raw fuel collecting on top of fuel pump Many more reports for same problem I found online that Mercedes would not react to, here is a typical one... Other Fuel System Pump problem of the 2012 Mercedes Benz E350 Date: 06/01/2020 1) My vehicle is emitting a very strong fuel smell and possible leak coming from the fuel pump. This is located under the rear seat, which had a recall. I believe that the item is faulty and should replace once again. I reached out to the dealership and to mb corp; but they do not want to take responsibility for their faulty design and product. The vehicle is not safe to drive with the strong vapors, which are dangerous to health. Also, I am forced to leave the vehicle outside of the garage because of my fear that this will cause a fire or explosion, resulting in massive house destruction and possible death.
