Gasoline smell inside the vehicle it sits with the windows up. usually more noticeable after filling with fuel. *tr

When the fuel tanks are more than half full, there is a strong smell of gasoline in the passenger compartment. this is apparently an ongoing problem with the c6 fuel tanks, as it has been raised by many people in various online forums. this problem also occurred in the c fuel, and i was told was fixed via a recall. has this problem prompted any recall activities for the c6. the dealer wants over $3000 to fix the problem.

There is a very strong fuel smell in my corvette after fueling up. the cabin smells like raw fuel, and it permeates the garage for a few days. the issue seems to subside after there is less fuel in the car. *tr

Strong smell of gas once the tank is filled over the 1/2 way mark. mechanic advises me of a leak in driver side tank. numerous posting of same problem on corvette forum.com. cannot park car in garage due to high gas vapors. cannot operate car when tank is full due to strong vapors inside car. google advises many people having same issues. estimated cost to repair is $2500-3000. this problem began early 2015 and has progressed to its current stage. note: corvette's use a saddle bag gas tank and is 2 bags connected. it appears the leak is where the 2 tanks connect.... updated 08/23/16 *bf the consumer stated the vehicle was repaired. updated 3/30/2017*js the consumer requested iformation concerning a par submition. *js

I noticed my fuel tank leaking fuel on the floor in my garage, my garage smelling like fuel, and increased fuel consumption. i took my car to a shop and they had to replace the fuel pump and tank (out of warranty) because the car was leaking fuel on the driver's side where the fuel pump connects to the fuel tank. *tr

Tl* the contact owns a 2008 chevrolet corvette. the contact stated that after refueling, strong fuel fumes emitted into the vehicle. the vehicle was taken to the dealer, but it was no diagnosed or repaired. the manufacturer was notified of the failure. the failure mileage was 13,000.

The gas tank on the drivers side is leaking from the top around fuel pump. very strong fuel odor. *js

After filling up with gas there is an extremely strong smell of gasoline in the car itself. only after half a tank is gone is the smell finally gone. *tr

The crossover pipe between the two fuel tanks started leaking fuel. this caused a strong odor of fuel to happen inside the garage and inside the car itself. fuel also splashed on various parts under the car. this resulted in a possible unsafe condition. *js

Strong odor of raw gas with car parked in garage. changed fuel cap but did not fix problem. concerned about possible explosion and/or fire as a result. dealer cannot find any visible leaks but odor remains. there are many posts on the corvette forum with the same issue and gm just seems to ignore the problem.. *tr

Gas fumes after filling tank and until level is below half.

When parked in my garage there is a strong smell of gasoline. i am afraid of a fire or explosion. purchased this car used from the previous original owner. *tr

Gas leaking at top of fuel tanks. gas fumes fill cockpit and garage when parked. evidence of gas dripping down back of drivers side fuel tank, next to exhaust. car can not be kept in an enclosed garage due to fumes and fire hazard. driving car also presents a fire hazards, because the fuel drips down onto hot exhaust. numerous other reports on the corvette forum of this same problem. too many to count. *tr

The driver's side fuel tank started leaking at the top of the tank. anything over 1/2 tank (the corvette uses two fuel tanks, a driver and passenger side) will result in extremely strong fuel odors and gas leaking from the top of the tank. the gas puddled on top of the tank, from leaking, could potentially drain or fall onto the hot exhaust while driving creating an enormous fire hazard. the fuel odor is overwhelming if the vehicle is parked in an enclosed space, say a garage, creating another fire hazard with the gas fumes. i am fearful to even drive the vehicle in the event that the worst could happen and the car catch on fire. *js

Due to a cracked fitting on top of the drivers side fuel pump, fuel is sprayed out and some pools on top of the tank. in the morning there is a strong smell of fuel inside and outside of the car. this would not normally be an issue on most cars, but because the fuel tanks are so hard to remove and expensive to repair the fuel pump is a $2,000 or more repair because transmission must be removed from the car to get to the fuel pump. on a related note gm has a really bad problem with the fuel level sensors going bad at low mileage. this sends an error code and a owner cannot pass a bi annual smog check until they pay the large sum of money to get the fuel level sensors replaced, once again having to drop the transmission to drop the fuel tank to replace a fifty dollar part cost around two thousand dollars. so my complaint is that the epa or federal and state smog laws and the error code, make the owner do the repair, to the fuel level sensor although it really does not affect the emissions of the engine, while it is perfectly fine to drive around with gas spilling out while driving. this is a serious environmental issue on top of the obvious safety issue that gm does not want to be accountable for... this needs to be fixed for all corvette with the low mileage leaking fuel pump and the owners should not be the ones at fault... *tr

Strong gasoline fuel smell when vehicle was parked inside enclosed garage. smell greatest after a recent fill-up. dealer did a smoke test and cursory visual check of fuel tanks without finding clear evidence of a vapor or liquid leak. finally on the third visit to the dealership, dealer was instructed to remove both fuel tanks from the car for a detailed inspection. driver side tank fuel pump was found to have a cracked liquid fuel line fitting requiring replacement of the fuel pump. *tr

When fuel tanks are full there is a strong fuel smell that fills the garage and leaks into my house. if the fuel vapors get high enough they could create a fire hazard as well as an inhalation and respiratory issues. *tr

Terrible gas fumes smell when i fill tank over half full! fumes even inside car when windows closed and when garaged the smell is so strong i think a open flame would cause an explosion! this has gone on for several years and not gotten fixed because of reported cost and i think gm should fix. i think this is a health and danger hazard and would hope gm would do the right thing and fix this on my 2008 corvette.

When i fill up my corvette at times is smells like gas in the car. also, my fuel gauge will at time go to zero even though fuel is in the tank. this corrects at times, but is getting worse. *tr

Following refueling, the cabin of the car fills with gasoline fumes. in most cases, the car most be allowed to air-out for hours prior to driving or storing in the garage. the quantity and concentration of fumes seems to be a significant fire risk. as it is transient, the dealer is not able to pinpoint, thus fix, the problem. this is a significant safety issue that warrants regulatory involvement!

Every time i fill the gas tank and the i start the corvette, the dash starts beeping, the gas gauge goes to zero, the "service fuel system" warning comes on and the engine light symbol shows in instrument panel. this remains for approx 10 - 12 starts on car and then it returns to normal and gas gauge shows present level of fuel. i have tried filling close to full and stopping, filling last part of tank very slow, but no matter what, every time i fill gas tank the fuel system indicators malfunction. forums online say to use techron from chevron to clean fuel system and have tried others for several years and still have problem. *tr

I began to notice a was smelling fuel in my car. as it got worse i went to grapevine chevy in grapevine, tx. they did a smoke test and found a leak in the drivers side fuel tank. initially they believed the tank was cracked but they would not cover the repairs citing a non-warranty issue. well after the leaking getting progressively worse to the point you could smell it inside the car while driving so i decided to fix it myself. when i removed the tank i found the fuel pump seals ruptured. i replace the thing and problem solved. gm never did anything at all to correct the issue. *tr

On september 13,2012 my fuel gauge stop working and it was not registering any gas level in the tank . i went to chevrolet dealership thinking that this was a repair which would fall under my vehicle extended warranty. i found out that there was a history code that came up in my car computer at 13,700 miles that my fuel system was falling. this is a code that you as the driver do not see nor do the tech at the dealership will see unless a diagnosis testing is done. the dealership had to call gm , because this fall under the factory warranty and this is something that happens with corvettes. the service manager stated sometime this fuel tank failure can happen at any mileage. this failure with my vehicle consist of right fuel tank had to be replace,fuel lever sensor had to be replace,fuel sensor had to be replace,line in tank had to be replace,crossover tubing had to be replace. if i know that this al fell under the gm factory warranty this would had cst me $2,024.09. this issues had to be know, this has happen with 2007 thru 2011 corvette's this is a known issues. you as a owner must be persist with the dealership and gm they will not want to pay error that they know is going on. i had to report this to the attorney general office in illinois and the bbb in illinois before something was done. i just wanted other owner to be aware of this have your vehicle check for this failure. *tr

Fuel pump cracked and spraying gas outside gas tank and onto car body. heavy smell of gas10

After refueling, there is a strong gasoline odor in the passenger cabin. *tr

After filling the car with fuel, i could smell gas instantly and i thought there was a leak. upon parking my car in the garage the whole garage smelled of fuel. after two days the smell was gone but it does appear every time i fill the car to some degree. it comes and goes now so you never know when it will happen. *tr

Fuel smell on driver's side of car...when stationary and while driving. reported to dealer during 1st year of ownership when car was new.

When i have over half a tank of fuel in the car it wreaks of raw fuel. it's most noticeable around the gas fill opening at the left rear quarter panel. if the car sits with the windows up i have to air out the cockpit before i drive it due to accumulated gas fumes. these fumes are due to an active leak that is present at all times when the fuel tank is ~1/2 full or more. this condition seems to be prevalent as there are countless complaints registered in the various web forums and youtube. it's apparently due to fuel accumulating on the exterior of the fuel tank where the fuel line exits the tank. that fitting fatigues and cracks over time. i can't believe this hasn't been addressed as a safety and health concern and/or chevrolet has not offered to repair this condition. not only is it an obvious fire hazard but gas fumes are a known carcinogen. it a shame that you have to risk your property and health or spend $1000+ to repair a manufacturer defect.
