Recalls
2 vehicle recalls from the manufacturer. Repairs are free. Check your VIN to see if one is still open on your car.
Seat belts Vehicle recall #00V117000 · 2000 · 77,952 vehicles
What's wrong: Some of these vehicles have front seat shoulder belts that May twist, allowing the webbing to become jammed in the retractor.
Why it matters: When the shoulder belt webbing becomes jammed in the retractor, the belt May be unusable.
The fix: Dealers will inspect for the presence of updated front shoulder belt bezels and where necessary, install new front seat shoulder belt opening bezel kits.
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…
