Time's Up: C6 Corvette Owners Now Facing the Music with Fuel Leak Repairs

C6 Corvette Fuel Leak Issue

For the uninitiated, the C6 Corvette, an engineering marvel from Chevrolet that defined American muscle from 2007 to 2013, has been hiding a little secret under its hood. We're talking about a notorious left-hand fuel pump module flange leak that has had owners on edge for years now.

Under the shelter of service bulletin 150682, General Motors magnanimously covered the cost of these leaky problems for a generous eight years. Owners of the sixth-generation Corvette were shielded from the financial burden of this defect, which could cause fuel odors, visible fuel droplets, or even trigger malfunction indicator lamps due to a leak in the fuel pump module flange.

The fix? A replacement of the faulty fuel tank fuel pump module. Courtesy of GM, of course, for vehicles up to 120,000 miles or 10 years from the date initially placed in service—whichever milestone arrived first.

Yet, all good things must come to an end, and the bulletin’s coverage for the 2013 models—the last of the C6 line—has officially ceased. This expiration puts current and future owners who are just now encountering this pesky issue (or will in the near future) in a bind, having to fork over their own cash for repairs.

Unsuspecting enthusiasts dreaming of owning a piece of American automotive history are advised to press the pause button. If a used C6 Corvette is on your radar, make sure this crucial repair isn’t looming in your future or use it as leverage to negotiate a deal that could save you from unforeseen setbacks and expenses.

With many Corvettes barely scratching the surface of their mileage limits and this issue potentially undiscovered until now, the path forward for owners and prospective buyers is riddled with considerations. The tale of the C6’s fuel leak is a sobering reminder of the complexities and unexpected costs of owning a legendary sports car.

Whether you’re currently navigating through your options or contemplating a dive into the Corvette world, let this serve as a crucial checkpoint in your decision-making process. The legacy of the C6 Corvette remains untarnished, but like all legends, it carries with it stories of both triumph and caution.
