Recalls

3 vehicle recalls from the manufacturer, plus 1 equipment/tire recall that can apply. Repairs are free. Check your VIN to see if one is still open on your car.

Fuel system Vehicle recall #03V454000 · 2003 · 79 vehicles

What's wrong: On certain passenger vehicles, a weld between the fuel tank inlet check valve and the fuel tank can fail.

Why it matters: If these parts separate, the driver May notice an odor of fuel, the service engine soon or check engine light May illuminate, and/or fuel May leak onto the ground. Fuel leakage in the presence of an ignition source could result in a fire.

The fix: Dealers will inspect the serial number of the fuel tank to see if it is on the list of affected tanks. If the serial number matches, the fuel tank will be replaced. Owner notification began November 4, 2003. Owners should contact Buick at 1-866-608-8080 or Pontiac at 1-800-620-7668.

Electrical Vehicle recall #05V157000 · 2005 · 34,186 vehicles

What's wrong: On certain sport utility vehicles, contamination on ignition relay contacts can cause high resistance. This can affect signals to the powertrain control module and, could cause intermittent vehicle stalls at any time.

Why it matters: The vehicle cannot be restarted immediately. If this were to occur, it could result in a vehicle crash.

The fix: Dealers will replace the ignition relay free of charge. The recall began on May 4, 2005.

Fuel system Vehicle recall #07V349000 · 2007 · 20,594 vehicles

What's wrong: On certain vehicles, variations in the manufacturing process or exposure to high ambient temperatures May lead to fracture of the fuel tank inlet check valve (icv).

Why it matters: A fracture May allow fuel vapors to pass through and allow droplets of fuel to accumulate on the side of the fuel tank. Fuel leakage, in the presence of an ignition source, could result in a fire.

The fix: Dealers will replace the fuel tank. The recall will be mailed in two phases with the first phase beginning on December 4, 2007. The second phase will be mailed on December 13, 2007.

1 aftermarket equipment / tire recall replacement parts sold to fit this car, not the car itself
Fuel system (other) Equipment recall #07E021000 · 2007 · 742 vehicles

What's wrong: Certain delphi fuel pressure regulators, p/nos. Fp10020-11b1, fp10026-11b1, and fp10027-11b1, sold after January 9, 2007, as aftermarket equipment for various passenger vehicles listed above. The universal pressure regulators (upr) were produced without an o'ring and retainer.

Why it matters: Fuel May leak, possibly resulting in a fire.

The fix: Delphi will notify owners and replace the upr free of charge. The recall began on April 23, 2007. Owners can contact delphi at 877-411-8770.
