Fuel smell when gas tank is full. Engine code P0456
Cracks have formed in the plastic cover over the fuel pump in the fuel tank under the back seat. Gas is seeping out when the tank is full.
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.
