Chevy Impala 2005 Gas fumes

For the last month I have been able to smell gas fumes in my car. I am really aware of the problem when entering or exiting the vehicle. I am not currently have any problems with the vehicle, but I since there may be a problem and I am wanting to intervene or prevent a serious problem from occurring. Please let me know what type of things could be happening to produce the noticeable gas fumes, so that I may have my car checked by a licensed mechanic.

    I have also been smelling a gasoline smell coming from the heat/air vents of my 2005 Impala. I did bring it over to a mechanic who couldn't smell anything. Now I smell the gasoline everyday but now that I know that it could be either a fuel injector leak or a fuel vent hose leak and that it can be fixed.

    Call the number listed below and give your VIN number to see if you have a defective after market fuel pressure regulator. There was a recall for 2005 Chevy Impalas. I have the same issue and I am the second owner, so the recall notification may have gone to the original owner. I'm calling in the morning.

The problem sounds like a vent hose has came off from the gasoline fill pipe. lots of car have the gassoline fill pipe running thru the trunk of the car. If by chance you were moving idems around in the trunk you could have broke off the vent hose. Not likely but possible, it is also possible that the hose is off on the out side. That is the fill pipe does not go into the trunk but runs in the finder well to the tank. Snow, Ice and Mud can take off the vent hose if the clamp is loose or the hose is split you will smell fumes. You do not smell them while driving as they are blown away. Check around the gasoline fill pipe area for gas fumes. The problem could also be at the tank end of the fill or vent hose. You may need a repair shop to fix.
good luck

Hi! You certainly have a gas leak, that could be emanating from your fuel tank area that is situated at the rear of the car,which is partly accessible by removing the rear seat of the car.This leaking fumes is very dangerous.You should treat this urgently.

I would have someone check under the front of car while engine was running. Maybe then a gas leak could be spotted. Did he check the charcoal canister-it's a gas vapor collector from the gas tank, and maybe located at front of car. If the canister is full and not working to purge the canister and send the collected fuel and vapors into the engine, it might be what you are smelling.

if inded the smell of exhaust is getting into your car i would suggest not driving it until it is properly checked by a licensed meachanic. it could be entering through your heater/AC blower and in return be fatal if left untouched for a period of time

2005 Chevy Impala exhaust smell


neither one of these would cause gas to leak. sure it is not coolant ? if you think it is gas it is not safe to drive car as it could catch on fire. possible cause would be a leaking injector.

2003 Chevy Impala Service Traction Sytem show on Dash


I can't answer the question about the gas fumes, but I had the same problem last year with the "Service Traction Sysytem" message and the Trac and ABS lights coming on in my Impala. Mine turned out to be because of a bad wheel bearing, that was causing the ABS and traction system not to work. I'm not sure if you've experienced this, but another thing that would happen with mine was that I would go to brake and have a hard time depressing the brake pedal, almost like it was pushing back. That is the point when the Trac and ABS lights came on.
