New heavy fuel odor in cab. I wonder how much fuel I am leaking. Where is the fuel that is being leaked out go" On a hot exaust system" Fuel line was replaced once by MB dealer. I think they used the same defective fuel line to replace the first one. One of the last times the van was in at the dealer they "didn't have time" to check the fuel line complaint. And there is no mention of my request in the service writers document that says I wanted it checked out.

In 2019, the fuel line was recalled for my Mercedes Benz Metris. I had this fixed and it was ok for a while. In 2020, it started smelling like gas again. We moved out of state in 2020 and in 2021 I took it into my local dealership to have them look at it. They replaced the fuel line again. Since then, it has smelled like gas badly. It gives me headaches and I feel unsafe driving it. The dealership told me last time that this would not be covered under the initial recall from 2017 but they fixed it "goodwill." I do not understand how this could NOT be covered since the issue is still not rectified. I absolutely need to get this fixed correctly as the smell is very very bad and I worry that fuel may be leaking into compartments somewhere that could cause a fire. I am concerned for my safety every time I drive it for my business. Mercedes has been unhelpful, I contacted them in 2021 to tell the dealer to fix it, they never followed up with me, I have put two formal complaints in recently: 3/11 and today, 3/17, with no response from Mercedes.

Raw fuel smell, leaking

- Madbury, NH, USA

Strong gas smell in the mornings after it sits overnight in my garage, especially on cold nights. It gets triggered when we open a door and the air starts circulating (before car is turned on). It started last winter and is happening still. I'm getting a little light-headed some mornings, especially when I can't open the windows (like when it's raining)

- Tallahassee, FL, USA

There is a fuel leak in the engine compartment. Mercedes replaced the high pressure fuel pump under warranty, but it's leaking somewhere else and it's no longer under warranty. It's an emissions issue(raw fuel leak) and a fire hazard. Checking the internet it seems this is very common problem w/O a common cure.

Vehicle not running, sat outside overnight in my driveway, temperatures in the 30sf, strong smell of gasoline around the vehicle happened more than once. The date and mileage are approximations. I can't remember the precise dates. It was this past winter. It was only after reading of others with the same problem that I decided to file a report

- Nashville, NC, USA

I can smell a strong odor of fuel almost every morning after being parked coming from the driver side hood region. More noticeable on cooler mornings. Very unpleasant to be working nearby while preparing for work. Smell is also noted in cabin prior to starting the engine. I have brought vehicle to the dealership about 5 times for this problem leaving it for a few days at time but they have not been able to detect or solve this constant and hazardous health and safety issue. I otherwise love the vehicle but this is something that should be identified and solved. This has been a problem for over 1 year.

****note - need more information, contacted consumer 5/21/2018. **** has anyone had that gas smell from the Metris front driver exterior? I've had it happen at least 1-2 times a month the last five months. Usually if it sits over night or it's been cold. I heard it was a rubber valve component on a fuel system. Called the dealer they said they can't do anything unless they actually observed it. Worries me though because it's a fire and health hazard when the Metris sits in an enclosed space garage over night. The gas vapors are very dangerous for breathing and ignition.
