Vehicle owners can now begin collecting documents and taking depositions to support their claims that Takata Corp. and Honda Motor Co. conspired to hide the risks of allegedly faulty air bags installed in their cars.

U.S. District Judge Federico Moreno in Miami on Wednesday kept alive federal racketeering claims the two companies had moved to dismiss.

The 107 consumers and four auto recyclers who are plaintiffs in the multidistrict litigation sued over Takata air bags that used ammonium nitrate. The buyers claimed they would not have bought their cars if they knew the air bags might kill or injure them with flying shrapnel, and the stigma attached to the air bags diminished resale values.
