With less than 40,000 miles on the odometer, I noticed a gas smell both inside the car and outside. I was able to access the fuel filter assembly on the top of the gas tank and found it had a substantial leak resulting in a puddle of fuel on the assembly. The car has never been in a wreck on had any damage that would cause this problem. I researched and found earlier years of the same model had this problem resulting in Mercedes Benz extending the warranty to 150,000 miles for this part. They have refused to warranty my car. This is a major safety issue and by releasing gas fumes into the atmosphere is an environmental problem as well.

I just recently discovered that after filling my car with gas, there is a strong odor of gas filled in the garage for over 24hours. When I googled the issue, I discovered that the federal safety agency did confirm issues with Mercedes E350 from 2003-2009. However, I have also discovered that several owners outside of that model year period are having the exact issue. I ask you please reconsider and open the recall so that Mercedes can pay to fix my car before a fatality occurs.

I noticed about to 6 months or less that my car would shut off or stall after starting ignition and also hearing water sloshing behind the dashboard and the radio does not work and the rear camera goes on/off which is safety hazard, and the Engine symbol remain lighted up even after checking all components. Also, on a few occasion my floorboard in the passenger back seat would be soak and wet. I took the car to my mechanic, and he inform that the drain valve was not working properly. after doing some research on the internet I found that this particular incident was happening in several of Mercedes years 2009-2011 E50, that it was a recall on the water drain system. Also, on 01/17/23 my sunroof was working without any problems, I attempted to close it and it stop midday and i hear the motor working, but the sunroof did not move, I did more research and found a recall on the bonding glue for sunroof and the glass was detached without warning. Even though my vehicle is not on the recall list, my car is having the same exacts problems and issues and reported by the federal safety agency. I would appreciate as response or advice to solve these problems, right now my car is a safety hazard to myself and other drivers. thank you for cooperation in this matter in advance.
