What stands out
No new NHTSA fuel system complaint has been filed on this vehicle in over 11 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering fuel system on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
This service bulletin provides the technician with additional information on fuels, fuel additives and fuel management.

The failure pattern owners describe
Owners cite two persistent fuel-system problems. First, the fuel gauge malfunctions early—some reports start at 8,000 miles—reading empty when fuel is present or simply quitting once the tank drops below half full. One owner's gauge worked until 2009, then remained inaccurate for years before complete failure. Dealers quote $1,500–$1,600 to replace the fuel sending unit inside the tank; independent shops struggle to source parts. Second, nearly half the complaints involve a strong fuel odor lingering around and inside the vehicle, especially when parked or after the engine shuts down. The smell intensifies in summer with ethanol fuel blending. Some owners hear fuel dripping onto the hot exhaust; at least one smelled it at just 8,000 miles. Chevrolet issued Special Coverage Adjustment 15682 for Primary Tank Module Flange leaks (TSB N150682), but that program has expired on many vehicles, and the manufacturer has denied repair assistance. One owner's 2007 Corvette caught fire in the rear wheel well and transmission area immediately after a track event, with the charcoal canister and emissions system consumed in flames and unidentified liquid drips found on the rear exhaust. The owner could not determine if these components caused the fire or merely burned.

Failure modes owners describe
Fuel gauge malfunction
Fuel gauge displays erratic readings or shows empty when fuel is present in the tank. Some owners report loss of function entirely after extended driving or once tank drops below half capacity.
When: Reported from 8,000 miles onward; one owner noted onset in 2009 and complete failure by 2013
Symptoms owners cite: Gauge reads empty with fuel in tank; Erratic gauge fluctuations; Gauge stops working after tank falls below 1/2 full; Complete gauge failure over time; Engine shutdown due to driver uncertainty about fuel level
Repairs/costs cited: Owners report fuel sending unit/fuel sensor replacement required, located in tank. Dealer quoted $1,500–$1,600 per owner; independent mechanics unable to source replacement parts.
Fuel vapor leak from tank and emissions components
Tank leaking fuel vapor and liquid fuel, often from the Primary Tank Module Flange. Owners report fuel smell both while driving and parked. Some detect visible fuel spots; others hear fuel dripping onto hot exhaust.
When: Failure mileage ranges 8,000 to 89,000 miles; odor present from very early in vehicle life
Symptoms owners cite: Strong fuel odor inside and outside vehicle; Fuel smell especially strong when parked or after engine shutdown; Visible fuel spots in driveway; Fuel dripping sound on exhaust when parked; Smell intensifies in summer with ethanol-blended fuel
Repairs/costs cited: Fuel tank liner replacement or fuel tank replacement needed. One owner quoted $2,678.87 for fuel vapor leak repair. At least one dealer replaced fuel tank at filler neck.
Recalls/TSBs owners mention: Special Coverage Adjustment 15682 for Primary Tank Module Flange fuel and vapor leaks; coverage has expired on some vehicles. TSB N150682 referenced. Manufacturer denied repair assistance on at least one claim. One owner received report number 71-904-403-313 but no assistance offered.
Engine fire after high-performance driving
Vehicle caught fire in rear wheel well and transmission area shortly after high-performance driver education event. Fire originated near transmission/gearbox; charcoal canister and emissions system consumed. Cause inconclusive but unidentified liquid drips found on rear exhaust pipe.
When: Immediately following high-performance driving event; vehicle traveling at 10 mph on county road
Symptoms owners cite: Fire visible in passenger rear wheel well area; Flames originating on top of transmission and gearbox; Charcoal canister and emissions components burned; Trunk floor melted onto rear exhaust pipe; Rear wiring near differential and transmission destroyed; Liquid drips observed on right rear exhaust pipe over differential
Repairs/costs cited: Vehicle required recovery by tow truck. Extent of structural and component damage significant; owner unable to complete full repairs.

What owners are reporting 2 most recent
I am smelling gas fumes coming from the driver side after driving. I can hear fuel dripping on the exhaust when I park the car in my driveway which is on an slight incline. If it is not dripping on the exhaust it's dripping on something hot because it makes a sizzling sound. Please help! Should have a recall about this problem in my opinion. Lots of corvette owners are dealing with this same…
Strong gasoline smell outside and inside the vehicle when gas tank is over 1/2 full. *tr

A quarter of owners report trouble before 25,000; a quarter make it past 60,100. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.

Independent shops typically charge around $1,200 for fuel system repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to fuel system?
