Fuel smell - possible fuel leak - the issue had been previously addressed with replacement of fuel subassembly in both saddle tanks. I believe that it is happening again ...

FUEL/PROPULSION SYSTEM

There was a strong fuel smell after the last 2 times I drove it. I took it to the shop and they tell me the evap canister was saturated and the fuel pump had small cracks in it likely seeping when the car heats up. I am having the fuel pump replaced, the evap canister and several seals/hoses in hopes it won't leak again.

FUEL/PROPULSION SYSTEM

After filling the tank with fuel, I was immediately aware of a strong smell of gas. I am always extremely careful not to overfill causing any fuel to escape. The heavy smell/escape of fumes is such that the car simply can’t be put in my garage. The risk of igniting and fire is a risk that is unacceptable. General Motors knows about this issue as they did notify me in 2017 that my car could have this condition and that if it did, they would fix it at no charge. I didn’t have the issue at that time so didn’t take the car in. So, now that I the problem, I have taken the car to Bradley Chevrolet in my town, Lake Havasu City, AZ and am told that in order to inspect the car for this issue, I will have to pay for 10 hours of labor ($2200) and only then will they see if they can find a new tank at another dealer. You see, GM no longer makes or has the tanks (according to their parts department). I have contacted their Customer Service Department and have a Case (#[XXX]). I am told that they will not participate going forward unless I spend the $2200 and then if they can’t find a new tank, they will put the car back together and send me home with it! It’s my belief that since this is a documented safety defect resulting in an apparent fire hazard that they would/should take care of it.

FUEL/PROPULSION SYSTEM

Strong fuel smell inside car as well as in garage. Drivers side tank does appear to have a leak when filled. Doing a search online it appears this is a common issue with this vehicle and that a recall/repair was created for owners however my 2007 (not the original owner) I suspect has since expired. In my opinion any defects that puts the owner and personal property at risk should be covered regardless of age.

FUEL/PROPULSION SYSTEM

We are having an issue with our vehicle leaking fuel on left side fuel tank. The vehicle is constant smell of gas on that left side. It has been a safety concern for us and the dealer wants us to pay at least $1200 just for diagnostic alone. There was a Special Coverage Adjustment for this issue but we were never notified. The notice is Special Coverage Adjustment 15682. I spoke with GM/Chevrolet Customer Assistance and spoke with [XXX] he said I would have to get diagnostic and that the fee could be applied to repair. I understand there is a time limit on most things but it seems that something that relates to safety issue should not have and end date. This is a type of car that most people just have as a collector car and you can see by the low miles that this is the case. I am not trying to get a repair on a vehicle that has 100,000 or more miles. It may seem trivial but this is important to me.

FUEL/PROPULSION SYSTEM

For last 3 years whenever I fill my vehicle with gas the garage smells of gas until the tank is less than half a tank... The other major issue is the vehicle will not come out of park multiple time. This has put me in embarrassing situations many times. I stay away from driving the vehicle so many times when I could be in physical danger .

FUEL/PROPULSION SYSTEM

I started smelling gas from my car two weeks ago. I discovered on Corvette Forum.com that this is a common problem. If the car is filled up over 1/2 tank gas will come out of the top and drip on the exhaust, which is very concerning. Chevrolet claims that the cars with this issue were recalled, but mine was not. This is one of two reoccurring issues with the C6 Corvette, and unfortunately, I am a victim of both. The other is the shifter locks in place, and the car will not come out of park. Chevrolet does not own up to the responsibility for this defective engineering as well. Please add me to the complaints for these two recallable issues as Chevrollet refuses to address the issue. Fuel dripping on the exhaust preplexes me why NHTSA has not got involved already.

There is a very strong fuel odor coming from the car when I shut it down, especially when I park in the garage. The smell is overwhelming. Seems like it's coming from the rear part of the car, drivers side. I don't see fuel leaking nor on the garage floor, but it is very evident there is a problem. This is a safety issue that needs to be addressed. thank you

FUEL/PROPULSION SYSTEM

Every time the fuel tank is filled to full (not past the click), there is a very bad fuel smell but no fuel leaking on the ground. I bought the car with 69000 and have noticed it every time I have filled the tank to full but never past the "click". I have read of many others having the same problem. I am afraid to park my car inside my garage. I have had fuel system parts replaced but it still continues. No leak has ever been noted.

FUEL/PROPULSION SYSTEM

I recently purchased my 2007 c6 corvette used. I did not notice anything until I started my drive home which was a 200 mile drive. the gas gauge was reading 1/4 tank of gas and dropped to empty. We stopped in at the gas station and filled the tank but once we did the gauge continued to read empty and a light displayed on the dash stating service fuel system. We continued to drive on our way home and we noticed a strong fuel odor inside the cabin of the car and distinctively from the driver side of the vehicle. I got the car home and noticed a few small drips in the garage that quickly evaporated. To the best of my knowldge I suspected that it was fuel. for the next week or so we did not drive the car but the garage smelled strongly of fuel. I parked it out side and the fuel smell in the garage went away. Odly after filling the tank a few more times the gauge began working again and the service fuel system message went away. It eventually showed an empty tank and then full again. I went to visit my local gm dealer to see if any recalls had been placed on my car over the years and they told me that there are no active recalls. However in my sear accross the forums I found gm bulletin 15682 (primary tank module flange fuel and vapor leaks) for my 2007 corvette. This bulletin was released in july 2016. perfectly matching the issue I am experiencing and was advised my member of many of the forums to file a concern with nhtsa. I have not yet had it inspected by the dealership because they want $1500.00 to inspect and repair because of the need to drop the drive train for proper access. I Would appreciate any assistance with this issue. I am scared to drive my care due to a fire related accident and it is my primary means of transportation.

JUST PURCHASED THIS USED CAR WITH LESS THAN 3000 MILES. I HAPPENED TO COME ACROSS THE FUEL LEAK ISSUE IN ONLINE FORUM. SINCE I REC'D INCOMPLETE SERVICE RECORDS, I DO NOT KNOW IF THE REPAIR HAS BEEN DONE TO MY CAR. THIS IS JUST NOT RIGHT WHEN TH EPROBLEM COULD CREATE A FUEL LEAK ONTO THE EXHAUST. IF THE PROBLEM WERE MADE A RECALL, THEN GM WOULD BE FORCED TO NOTIFY ME AS THE CURRENT OWNER SO THAT THE PROBLEM COULD BE FIXED BEFORE THERE IS A FIRE RESULTING FROM FUEL LEAK.

RECENTLY, 03/01/2021, FILLING GAS TANK TO OVER 1/2 FULL ON MY PARKED 2007 C6 CORVETTE, WITH 30,360 MILES, PARKED VEHICLE CAUSED STRONG INTERIOR GAS ODOR. ON FURTHER INVESTIGATION AND COMMUNICATION WITH GM, I WAS INFORMED FUEL PUMP WAS A KNOWN ISSUE. THE FUEL PUMP WAS THEN REDESIGNED TO SOLVE THIS ISSUE; HOWEVER, REPLACEMENT OF FAULTY FUEL PUMP WAS ONLY GIVEN A WARRANTY EXTENSION INSTEAD OF RECALL. CONSEQUENTLY, I WAS NEVER GIVEN A NOTICE OF THE DANGEROUS CONDITION THAT EXISTED IN MY VEHICLE, WHICH IS NOW BEYOND THAT EXTENDED WARRANTY PERIOD FOR SPECIFIC PARTS; AND, AS AN OWNER, I WAS NEVER NOTICED OF THIS KNOWN ISSUE BECAUSE IT IS NOT REQUIRED UNLESS IT IS A RECALL. APPARENTLY THE CAR HAS TWO TANKS THAT ARE SHARED. WHEN OVER 1/2 FILLED, GASOLINE CAN LEAK AND PUDDLE ON TOP OF THE TANKS. WHEN MOVING, THE GASOLINE CAN THEN LEAK DOWN ON THE HOT EXHAUST AND CAUSE A FIRE. I AM NOW FEARFUL OF DRIVING MY CAR DUE TO THE GASOLINE VAPORS, AND WAS ADVISED BY VAN CHEVROLET TO HAVE THE CAR TOWED FOR REPAIR, AS THIS ISSUE COULD CAUSE A FIRE OR EXPLOSION, OR THE FUMES COULD CAUSE THE DRIVER TO PASS OUT AND HAVE AN ACCIDENT. THE COST OF THIS REPAIR IS OVER $2300-$2500! I WOULD HAVE HAD IT REPAIRED IF IT WERE A RECALL BECAUSE I WOULD HAVE BEEN NOTIFIED OF THE HAZARD. CAR WAS PARKED WHEN I FIRST NOTICED THE PROBLEM AND HAVE NOT DRIVEN IT SINCE. THE RISK OF A FIRE, EXPLOSION, OR ACCIDENT IS TOO GREAT UNTIL IT IS REPAIRED! GM ASSIGNED CASE# [XXX], BUT IS CURRENTLY INFORMING THAT IT IS NO LONGER COVERED. SINCE NO NOTIFICATION WAS GIVEN TO OWNERS, OWNERS WERE NOT AWARE OF THE ISSUE UNTIL TOO LATE, SAVING GM MILLIONS OF DOLLARS, AS THEY WOULD HAVE BEEN RESPONSIBLE FOR REPLACING LARGE NUMBERS OF THE FAULTY FUEL PUMP HAD A RECALL BEEN ISSUED WHICH REQUIRES REGISTERING RECALLS WITH THE GM DEALERS, AND NOTIFYING THE OWNERS.*DT*JB INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).”
