According to the US Environmental Protection Agency (EPA), General Motors Corporation will recall approximately 400,000 passenger cars that exceed the federal emission standards for carbon monoxide. The affected vehicles are 1993 model-year Chevrolet Luminas, Oldsmobile Cutlass Supremes, Cutlass Supreme convertibles, Pontiac Grand Prixs and Buick Regals with six-cylinder 3.1 liter engines.
The EPA said GM will replace defective parts of the emissions-control system, as well as reprogram a computer memory chip in the Cutlass Supreme convertibles to reduce carbon monoxide emissions. GM will notify owners by letter and repair the recalled vehicles free of charge.
In December 1995, GM recalled and planned to repair 470,000 Cadillacs the EPA alleged were equipped with illegal devices to defeat pollution controls as part of a $45 million settlement. In June 1997, the automaker recalled 44,000 Cadillacs for an emissions repair and made payments totaling $1.1 million as part of a settlement with the California Air Resources Board.
