Gas smell in the cabin by model year
What owners say
Filled up gas and strong gas smell can be smelt throughout the car and Check engine light came on, took car to auto zone for report. Stated emissions code was listed. Was told to replace gas cap and code should clear. Replaced gas cap, still had code. Took car to shop and was told this model has this issue with this specific year and newer, and the problem could be one of 3 things. Replace gas cap, did that, replace fuel pump closing cover, did that, replace purge valve canister, did that. Check engine light still comes on and strong gas smell still exist after each fill up. Mechanic told me reach out because there was a recall on this same model a few years back...
Gas smell inside the car. Fuel leak when gas tank us full.
Raw gas smell after filling up with gas .
Strong smell of fuel after filling up gas tank 3/4 or more for the past 12months
Strong gasoline smell when I fill my tank up and park my car inside my garage. So strong that I worry about explosion due to my water heater with pilot light in the garage. I frequently open the garage door to let the accumulated gas odor dissipate or have to move the car outside. Strong gasoline smell goes away once the fuel level goes down about 1/8 to 1/4. This has been going on since 12/20/2020.
Strong smell of gasoline when tank is filled up.
Strong smell of gasoline when tank is filled up. This has been an ongoing issue for a few months now. Don't know much about cars so didn't think much of it until I had a couple of people ask why my car smelled like gas. They let me know that it may be a gas leak somewhere.
Heavy gas fumes from vehicle especially when fuel fill up.
Tl* the contact owns a 2010 mercedes-benz c300. A few years ago, the contact detected a fuel odor coming from the vehicle. The vehicle was taken to mercedes-benz of foothill ranch (81 auto center dr, foothill ranch, ca 92610, (949) 354-0112) where it was diagnosed that the rear passenger side fuel fender seal/ seal ring failed. The vehicle was repaired, but the odor recurred. The vehicle was taken back to the same dealer where it was diagnosed that the fuel filter housing was leaking and the rear padding and lower seat cushion were saturated with fuel and needed to be replaced. The contact stated that the entire rear seat was replaced. The vehicle was repaired. The manufacturer was notified of the failure and did not assist. The approximate failure mileage was 108,989.
Exactly as described with other models, there was a strong gas odor inside and outside of the vehicle. It worsened after the car was refueled. It got so bad that fumes were seeping into the house from the garage. While driving, all windows had to be down. After researching online, I found out that there was a recall on other mercedes years and models for the same issue. The gas tank gasket is defective. My car is not included in the recall and I must pay to fix the hazardous condition.
Smelling gas fumes inside the car, has gotten light headed when driving, and my gas gage does not work.
