Recently reported FUEL/PROPULSION SYSTEM problems on 2008 Chevrolet Corvette

Strong fuel smell coming from car when the car was turned off. smell started on the outside of the car, but eventually (over the course of a couple days) leaked into the cabin. by this time the car also smelled of fuel when on. left car in garage for a few hours while hiking, came back and opened the garage and started coughing from all the fuel fumes. no visible liquid leaks, but the smell was very strong. i aired out the garage and parked the car outside and took it in the next day, was told the fuel pump cracked. this shouldn't happen after 7 years of low to moderate use. this was also during thanksgiving - if i had gone away for the holiday, the spark from my gas hot water heater may have caused an explosion while i was away. the amount of fuel vapor in my garage was enough to cause difficulty breathing. also, while driving to the dealership, my father (following in another vehicle) said he smelt a strong scent of fuel whenever i stopped at a light. considering how close the left fuel tank (where the fuel pump is located) is to the hot exhaust pipe, i'm lucky the fuel didn't leak onto the pipe and start a fire with me inside. as a side note, as soon as i described the problem to my service rep at the dealer they said this has actually been a common occurrence over the past few months for the 2008 vehicles. when i talked to the rep, there is a new part on the market that gm will replace my old, cracked part with - which tells me gm knows about this problem, and yet failed to disclose this could happen.

Only owner of 2008 c6 coupe. garage kept. gas fumes can be smelled near back of car after car is filled with fuel. smell disappears when gas tank is less than half full. i can't keep my car in the garage. i was told that there was a crack in the gas tank. $3,000 repair!

There is a strong smell of gas inside the car. there is also a strong smell of gas in the garage after the car has been parked for awhile.

Fuel smell coming from fuel tank, when tank is more than 1/2 full, inside of car smells of gasoline. when car sits in garage it fills the garage with fumes, very dangerous and it seems like i am 1 of many with the same problem on the c6 corvette. seems like the fuel tank seems are splitting from what everyone has said.

Overwhelming fuel smell when leaving the car parked in the garage or when left parked outside the smell builds in the interior. upon inspection there is a leak from the top of the driver's side fuel tank that drips down the rear of the tank near the hot exhaust.

My car is not able to be parked within the garage, the fuel smell is blatant and overwhelming, making me dizzy at times. this must be fixed. it is evident at all times, and is very toxic.

Fuel odor in the garage right side gas tank has fuel leaking down the tank after fill up there is a gas water heater in the garage if this is not a safety issue what is? after doing some research this is a very common problem why no recall by gm? noticed odor for over a year took it to dealer and found the leak.

Strong, overbearing smell of gasoline inside and outside of the car at all times. i cannot drive it because of the fumes. i cannot park it in my garage because it fills the entire area with the smell of fuel. this is dangerous. this needs to be fixed. this is my only vehicle and i cannot drive it due to the safety risks alongside the nauseating fumes, and cannot afford to fix the problem. (chevrolet dealer quoted me $1,600 just to look for the problem, then unknown costs to fix it) this many people complaining about the same issue are not wrong. gm needs to do a safety recall before someone gets hurt or worse.

Strong smell of gasoline inside and outside of my 2008 c6 corvette with no visible fuel leaks. the overpowering vapors leak into the house when parked in the garage making a highly dangerous flamable safety issue . the local chevrolet service center quoted $1,400 to pull the fuel tank and replace a charcoal canister, and they indicated this was a known concern. in researching this issue on open forums, found numerous identical issues. my vehicle has only 48,000 miles. this should be a safety recall at a minimum before a vehicle catches fire or explodes in a closed space near gas water heater with pilot light.

Strong fuel odor after filling car with gas, almost unbearable in closed space (like a garage). dealer readily noticed odor when car was taken in for service. odor originates near fuel fill door (driver's side, rear wheel well). dealer diagnosed fault as leaking fuel tank, possibly due to cross-over pipe connecting left and right halves of tank or fuel pump; probably high on the tank; no gas drips on garage floor, evaporates before dripping. estimated cost to repair >$1550 not including parts. fuel vapor leaks are dangerous. this type of problem has been described for corvettes as early as the 1996 model year.

Leaking fuel / or strong raw fuel smell in cockpit, filler neck or top of fuel tank!!! no fuel on pavement?? replaced fuel cap - did not fix strong raw fuel smell... suspect leak on top of tank or filler neck...

Strong smell of gas when the car was sitting. smell both inside and outside of car. took in for service and found cracks in the driver side fuel tank at the seems of the plastic gas tank.

Rhadamanthus gas smell in cab. took to dealer and they said it was a cracked elbow on the drivers side fuel-pump. it was not covered under emissions so it cost me $2000.00 to have fixed. there are many complaints about this same problem on numerous forums. this is a serious safety issue and g.m. will not address it. i'm pissed. a recall is needed. please do what you can to get this recall.mthanks

When the gas tank is filled half way or more the odor of gas is overwhelming out side the vehicle driver side and the smell of gas permiates throughout the garage which is attached to my home.

Over the past few months, i have been noticing a strong gasoline odor emanating from the left rear portion of my 2008 corvette. without having the car on a lift, visual inspection of the driver side fuel tank reveals a "wet" look creeping down the rear side of the tank. again, without the aid of a lift, i was able to fix a rag on the end of a device and swipe the "wet" area. the rag picked up a bit of this "wet" and a simple sniff left no doubt that the "wet" is a gasoline leak that appears to be coming out the top of the tank.

Started noticing an emitting of gasoline odors on the drivers side by the rear wheel well. replaced the gas cap, odor still there noticed odor after filling gas tank. odor remains until gas tank falls at below 1/2 tank. advised possibly fuel cross over line between two tanks this seems to be a more typical occurrence on c5 and c6 corvettes.

On 8/20/2015 i filled my car up with gas and as soon as drove away the cockpit stared to smell like gas i thought i may have spilled some om shoe, the odor was getting overwhelming . when i got home nothing was on my shoe so i looked around the car for a leak.i didn't see or find anything but did find a bad gas smell from the driver side rear. the next morning i went out to the garage, there was a odor of raw gas it was extremely bad for i feared that my house would blow up do to the water heater having a flame. i immediately took the car out of the garage . the car is now at the dealer and waiting for the prognosis 8/22/2015 i will report more when i find out what they found .

Strong odor of gasoline after fill-up. no trouble codes like evap, etc. turning while vehicle in motion (~20mph) increases gas odor. i stopped driving vehicle for fear of a vehicle fire. i fear this is the dreaded fuel pump fitting crack/failure that other c-6's have experienced. does someone have to die before corrective action is taken?

Strong fuel smell coming from vehicle

Strong gasoline odor coming from left rear side of vehicle at fuel filling area and below. usually notice when the vehicle is turned off in the garage. odor lingers even into overnight, next day garage has gasoline odor

There is a bad fuel leak that produces horrible amounts of gas vapor that fill any area the vehicle is parked in as well the fuel leaks down the driver rear quarter panel to the hot exhaust. this situation has the potential to be very devastating not only to property but also to the operator while driving the vehicle. it is a very unsafe condition. the vehicle is currently getting inspected at the dealership

During the july time frame i parked my car in my garage. the next morning i went into the garage and smelled an overwhelming odor of gas fumes. i immediately removed the car from the garage and parked on the street. i went to work that day and while driving i smell gas fumes in the cockpit. i parked my car and opened the trunk. i smelled gas fumes there as well. it has come to the point i will not park my vette in the garage for fear of the house burning down. i do not drive my car to work for fear of the car exploding and killing me. i took the car to the dealership. they could not find anything wrong with the car. they did not detect the smell of gas fumes either. i fear parking the car in the garage because i do need a place to live. the car will remained parked outside until this dangerous situation is resolved. lets be proactive not reactive. thank you.....[xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tr

After fueling my 2008 c6 corvette and parking in the garage there is a strong fuel smell. as a test removed it from garage and smell stopped.

The car had approx 15000 miles on it when i began to notice a strong smell of gasoline in my garage and cabin of the vehicle. i could also see where fuel had been running down the inside of the drivers side fuel tank. the gasoline vapor was overwhelming in the cabin and garage. a search of the internet revealed a long history of leaks on the fuel module on top of the drivers side fuel tank. my dealer confirmed this and quoted me $2100 to replace the cracked fuel module. the leak drips very close to the exhaust pipe and would appear to be a serious safety issue. i strongly recommend an investigation and or recall of these cars based on the number of complaints on the internet.

Corvette has fuel leaking from the top of the tank due to hairline cracks on top of fuel pump elbow. car can not be topped off sprays out under pressure. presents a fire hazard and should be looked in to by nhtsa for recall. so it does not hurt any one or some ones car catches on fire. gm should have this fixed there was also an issues with the c5 corvettes previous generation that was recalled.

I have a strong fuel smell after filling my tank most noticeable when sitting still or parked.

My 2008 chevy corvette has a bad gas smell everytime i get in and out of the vehicle. i have read that many people have this same issue and its caused by the plastic used for the gas tank. gets a crack and leaks from the back down to the exhaust. possible fire hazard. let me know asap of any recalls etc. thank you

Gasoline/fuel odor with full to half full fuel tank. odor in interior and around exterior of vehicle. research via internet indicates problem is widespread.

Parking my coupe inside my attached garage, after driving her (vette) the day before. the next morning i open my entry door that leads into garage. after opening door i immediately smell the unique aroma of gasoline/fuel emmiting throughout my entire garage. i did observe droplets of gasoline on my garage floor below coming from the drivers side fuel tank.

While the vehicle is parked, especially after filling up the gas tank, the vehicle emits the strong smell of gasoline. the smell of gasoline fills my garage when the vehicle is parked overnight. the concern is that the vehicle may catch fire if exposed to a spark or some other type of heat source such as the vehicle's exhaust. according to the dealership there is no recall for this issue.

There is a gasoline leak somewhere on the car that is filling the garage with a very strong gasoline smell. there is no gas on the garage floor. i suspect a vapor leak at the top of the gas tank at the fuel pump/gage sender location. car is now parked outside for fear of fire in the garage. have an appointment with the chevrolet dealer on monday 5-4-15 to find leak and repair. currently believe this could be a very serious safety problem! *tr

I entered garage after car being in garage all night, garage was filled with gasoline fumes. *tr

Recently bought a use 2008 corvette. went to dealership to pick up and as i approached vehicle a very strong odor was emitting from the vehicle and once i opened the door the order was strongly present inside also. i originally figured that the salesman had over filled the tank since he said he would fill the vehicle with gas as part of the sale. the odor continued for several days, even as the gas was used. i drove the vehicle and tried several refills (ensuring not to top off) but the odor is still present. no matter the volume of gas in the tank the strong odor of gasoline is present outside and inside. research on the internet revealed numerous complaints of the same problem from other owners of that model (c6) indicating a problem with a defective fuel line (elbow on the top of the drivers side gas tank coming from the fuel delivery system and associated seals/gaskets). there is even a youtube video by an owner showing the problem and his personal repair of the defect. i saw that the repair can cost an owner upwards of $4k dollars. since this defect is so prevalent and obviously not something that can be caused by owners negligence, these vehicles should be recalled by the manufacturer and repaired. this condition is a fire hazard and should be looked at immediately.

While parked in the garage after driving there is a strong gas odor emanating from the vehicle. *tr

I have written before on this problem. do you folks ever acknowledge receipt of a complaint. the car has a strong smell of gasoline until the tank is half empty. this is a large problem affecting many corvette owners and the fumes are very bad inside and outside the car. there was no date of incident and it did not arise from any accident. *tr

Driver side fuel tank is leaking fuel. lifted driver side and can visually see the tank is wet from fuel leak. *tr

Gas smell in car and garage. *tr

Started noticing a strong smell of gas a few weeks ago in my garage where i park my car. i thought maybe it was lawn equipment, or my motor bike. i took all those out one at a time over night, and still noticed the smell. left my car out over night, no smell, put back in the garage, and the smell came back! fills the whole garage and house after about 12 hours!!! in searching the corvette forums, it appears that many others are having this problem. it appears to be the fuel pump where the fuel line hooks up, gets small hair line cracks. this is obviously a huge fire hazard! *tr

I have a fuel smell/odor coming from my 2008 corvette coupe when i fill the tank to full. i took it to a local mechanic and it cost me over $1400 to repair. the mechanic informed me that it was a small plastic part on top of the drivers side tank that was faulty. i would notice the strong smell when the car was parked in my garage.

I began to notice a strong gasoline smell next to my rear driver's side of my 2008 chevy corvette coupe. i just did a search online and found numerous others with the same complaint for the same model. seems the fuel tank leaks after cracks develop. *tr

My 2008 c6 corvette has a problem with a fuel smell coming from car when i fill the tank. i parked the car in the garage after a refill one evening. my wife returned home from work a couple of hours later and when she opened the garaged she was overwhelmed by the gas fumes, afterwards i parked my car outside of the garage. i took my car to the chevy dealership for a diagnostic test and they informed me that i had a leaking fuel pump and i needed to replace the pump as well as the left fuel tank (repair cost estimate $2900). the mechanic stated that he'd changed several of pumps on c6 corvettes in the past. so i asked him if this was such a frequent occurrence, was chevrolet aware of the this safety issue. this was the response " i cannot answer that question sir". i truly believe this a safety defect that may cause someone their life one day. either with someone parking the car in the garage in the fumes may cause the hot heater to ignite the fumes or it leaks down onto an hot exhaust when driving the vehicle. *tr

Very strong fuel odor coming out of rear driver side. odor seems stronger when fuel tank is at 80% or more. *tr
