Slight gasoline odor when parked in garage

Have you ever overfilled it by topping the tank off?

If you're asking if there is a common issue with this, I would say No based on what I've read and experienced (although mine is a Gen II). My initial concern would be what Ed said. Then I would get under the car and under the hood and and try to locate the source. Shouldn't be all that hard I don't think. The source may be something else in your garage, too. But definitely not something I would ignore.

Small leaks of gasoline won't necessarily leave noticeable marks on the floor if it evaporates quickly and doesn't puddle. Not like oil or other car fluids. Fumes from evaporating gasoline are potentially ignitable in a closed space so if you have a water heater or other appliance with a pilot light in your garage, you may be in danger if you don't eliminate this hazard. In the meantime, I would try to ventilate the area as appropriate or consider parking it outside for the time being.

Any other info you can give us? Was any recent service done to the car (within the last month)? Any accident or other incident?

 

Considering that it has just been going down the road.......where the wind will mostly remove the smell of a tiny leak.......I think you should consider that you have a substantial leak and get it checked out .......SOON.

IF......the leak happens to be on the high pressure side of the fuel system, a small leak can become bigger in a hurry and potentially start a fire.

 

I park my 07 since new in the garage and have never ever smelled even faint wiff of gas and I have a good sniffer.

I agree with Easy any gasolene smell in the garage is emergency in my book. I would at the very least park it outside till its remedied. Lots of youtubes with roofs missing from explosions in the garage..

 

Winter gaso has a lot more light butanes so could help explain the smell. It's getting harder to smell gaso with lower near-zero sulfur regs coming into effect but the regs are being phased in gradually, and I am not sure if smaller stations have some exclusions, so you could have got a smelly batch of winter gaso.

EDIT: But by all means check it out at a shop if you have a concern

 

Just remembered that some folks are reporting leaks in the filler tube resulting in water entering their tanks. That's a place to check and ensure it's not spilling or leaking during fill-up. But if it's not there, keep looking.

 

Not normal, not good.
Get it checked.

 

I think the gas cap, or something in that vicinity, will vent a bit if air pressure gets too high in the tank.

Typically occurs after an extended summertime drive. What are your ambient temps like?

 

I think if it's venting, it'd be right after a drive, and if you're in a quiet garage you'd hear it. I think.

 

We did have one Prius fire reported here recently that seems like must have been some kind of fuel leak under the hood. They were parked outside their garage with some damage to garage. Believe it was Gen3.

 

I swear...
LOL! I hadn't read all the way to the bottom and was just about to ask you if you had any other gas powered items stored in your garage.

Damn...too late for what could of been a great brilliant save on my behalf!

Well at least that DID turn out to be an easy fix in relationship to The Prius.

 

It might be as simple as spilled gasoline around the filler.

 

If only someone had suggested that......

 

i know, i was thinking chainsaw...

 

Been there....done that. The tubing in my trimmer cracked after years of use and I had it leaking minimally in the garage. Bought a repair kit from OEM Replacement parts for Tools, Appliances, Consumer Electronics and more | eReplacement Parts
and got it fixed up.

Glad that was it and not the Prius.

 

that's why i have the ryobi 18v lithium system.
