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.
Wheels Vehicle recall #99V072000 · 1999 · 352 vehicles
What's wrong: Some of these wheels have a mounting surface that was not machined correctly, causing the wheel studs to break.
Why it matters: The tire/wheel assembly could separate from the vehicle, increasing the risk of a crash.
The fix: Dealers will inspect the wheels and replace all wheels with date codes indicating that they May not have been machined correctly. The wheel mounting studs at any location where a suspect wheel was installed will also be replaced.
Transmission & drivetrain Vehicle recall #99V089000 · 1999 · 99,333 vehicles
What's wrong: These vehicles fail to conform to the requirements of fmvss no. 102, "transmission shift lever sequence." a retaining clip, which secures the manual valve to the linkage of the transmission detent lever, can become loose under a combination of possible driver shifting maneuvers and allow the link to become disconnected from the manual valve.
Why it matters: If the link disconnects, the driver's indicated prndl state May differ from the hydraulic state of the transmission. If the driver selects 'drive' and the transmission is actually in 'reverse', a vehicle crash could occur.
The fix: Dealers will replace the manual valve/link assembly with a replacement manual valve/link kit, featuring a spring-type fastener.
Fuel system Vehicle recall #04V090000 · 2004 · 910,873 vehicles
What's wrong: On certain passenger vehicles equipped with 3800 v6 (l36) engines and certain delphi fuel pressure regulators, the regulators have a much higher than usual rate of fuel leaks. A leak can allow fuel to enter the intake manifold through a vacuum line. If the engine does not start when cranked, the fuel from the leaking regulator and a mistimed spark can cause a backfire.
Why it matters: The backfire can rupture the intake manifold. The rupture of the intake manifold can displace a fuel line, pulling an injector out of place, and causing a fuel leak and possible fire.
The fix: Dealers will install new fuel pressure regulators with improved diaphragms. The recall will be conducted in phased mailings. Phase 1 began on June 30, 2004, and phase 2 began on September 30, 2004. Owners should contact Buick at 1-866-608-8080, Oldsmobile at 1-800-630-6537, or Pontiac at…
1 aftermarket equipment / tire recall replacement parts sold to fit this car, not the car itself
Exterior lights Equipment recall #09E012000 · 2009 · 16,270 vehicles
What's wrong: These headlamps fail to conform to the requirements of Federal Motor Vehicle Safety Standard no. 108, "lamps, reflective devices, and associated equipment." these lamps do not contain the required amber side reflectors.
Why it matters: Decreased lighting visibility May result in a vehicle crash.
The fix: Sabersport will notify owners and offer a full refund for the noncompliant combination lamps. The safety recall began on May 11, 2009.
