General Motors Co. on Wednesday filed a racketeering lawsuit against Fiat Chrysler Automobiles NV, alleging that its rival bribed United Auto Workers (UAW) union officials over many years to corrupt the bargaining process and gain advantages, costing GM billions of dollars.

GM also alleged that Fiat Chrysler's former CEO, the late Sergio Marchionne, was central in the scheme.

The No. 1 U.S. automaker said it will seek "substantial damages" from FCA that it said would be reinvested in the United States to create jobs, but did not specify an exact amount.
