Approximately 80 class-action lawsuits were filed on behalf of purchasers of new motor vehicles in the U.S. since January 1, 2001 against General Motors and other car manufacturers alleging a conspiracy to prevent the U.S. sale of vehicles produced for the Canadian market and sold in Canada. The lawsuits alleged that new vehicle prices in Canada are 10% to 30% lower than those in the U.S., and that preventing the sale of these vehicles in the U.S. resulted in the payment of higher than competitive prices by U.S. consumers. Without conceding liability, General Motors of Canada Limited agreed to settle several state court cases in 2011 for $21 million.
