DOJ cracking down on auto parts price-fixing

"These international price-fixing conspiracies affected more than $5 billion in automobile parts sold to U.S. car manufacturers," he continued. "In total, more than 25 million cars purchased by American consumers were affected by the illegal conduct."

Holder said the Justice Department's investigation of auto parts industry was "the largest criminal investigation the Antitrust Division has ever pursued, both in terms of its scope and the commerce affected by the alleged illegal conduct.

"Never before has the Department of Justice simultaneously announced the breakup of so many separate antitrust conspiracies," he said. "And today’s charges were filed in three different U.S. District Courts – in Detroit; in Cincinnati; and in Toledo, Ohio."

Holder said the investigation "uncovered involved more than a dozen separate conspiracies aimed at the U.S. economy."

"Although these cartels operated totally independently, they all had one thing in common – they targeted U.S. manufacturing, U.S. businesses and U.S. consumers," he said. "As a result of these conspiracies, Americans paid more for their cars. And American companies such as Chrysler, Ford and General Motors, as well as U.S. subsidiaries of Honda, Mazda, Mitsubishi, Nissan, Subaru and Toyota – were victims of the illegal cartels."

Holder promised the DOJ would continue looking into the auto parts industry.

"Our work isn’t done," he said. "We will continue to check under every hood and kick every tire to make sure we put an end to this illegal and destructive conduct."
