“Strong smell of petrol in the mornings, seems to be under the hood. I inspected the fuel lines from the fuel tank to the engine underneath and could not find any drips or wetness. Did some research online. There was a recall on other models for this problem. I called mercedes customer service but there is not a recall for this on the 2017 mercedes E300”

NHTSA complaint #11389383, filed 2021-01, 70,000 miles

“Low pressure fuel line needed replacing. This was due to a fuel smell in the cabin when cold. Mercedes indicated fuel lines are considered wear and tear and even though it was leaking , was not covered under pre owned warranty or recall. The fuel line appears cracked due to misinstallation vs rubber cracking due to age as one side was pristine and the other had a crack in it. This is noticeable at idle , when the car is cold and the heat is blowing.”

“I own a 2017 mercedes benz e-class. I'm starting to smell gasoline in the cabin and also outside of my vehicle. I tried entering my VIN number to see if any recalls. There is something listed for the smell of gas. Can someone help me regarding this matter.”

“It appears according to the technician that the entire fuel system has shorted out at once while I was driving down the road and my car died at once while nearly causing a wreck while losing all power steering and control.”

NHTSA complaint #11419930, filed 2021-06

“Vehicle emits a strong odor of gasoline when cold. It was mainly noticeable on the outside of the car at first, but now when I turn on the air inside the car (not on AC mode), I started smelling the odor of gas in the cabin. I have taken the car for possible repairs, but am told on two separate occasions by an independent service center that the odor can not be duplicated. There are recalls for the same issue on different models, but as of yet, not on this particular year model. …”
