Recalls
2 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.
Seat belts Vehicle recall #97V096001 · 1997 · 586,058 vehicles
What's wrong: The outboard safety belt webbing on the driver's and/or passenger's seat can separate during a frontal impact.
Why it matters: If a separation occurred and there were secondary crash events or vehicle rollover, there would be no belt restraint of the occupant and increased injuries could occur.
The fix: Dealers will install a protective cover over the recliner mechanism.
Brakes (hydraulic) Vehicle recall #97V146001 · 1997 · 146,167 vehicles
What's wrong: 3l engines. The front brake line can contact the left-hand side of the engine oil pan causing the brake line to wear to the point of brake fluid loss during brake application.
Why it matters: Brake fluid loss can reduce braking effectiveness and increase stopping distances resulting in a vehicle crash without prior warning.
The fix: Dealers will inspect the clearance between the oil pan and the brake line. If the clearance is 6mm or less, dealers will install an additional brake line clip and if there was contact between the oil pan and brake line, the front brake line will be replaced.
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.
