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. …
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 [redacted] 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. …
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.
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.
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.
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
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 .
