The companies coordinated the prices and allocation of supplies of wire harnesses to the respective car manufacturers, the Commission said. The cartel contacts took place in Europe and Japan.
For Toyota and Honda, the participants rigged a series of tenders for the supply of wire harnesses, including all tenders for supplies to the European manufacturing facilities during the cartel period. For Nissan and Renault, the participants rigged – or attempted to rig – single tendering procedures for some individual models, according to the Commission.
Leoni said its involvement was confined to a single instance between May and December 2009 when a French subsidiary was involved in an isolated infringement. There was no harm to the customer and Leoni cooperated fully with the authorities, it said in a statement.
The fines for the suppliers were cut by 10 percent, on top of other discounts, after they admitted to taking part in the cartels.
The sanctions from the European Commission are expected to be the first of several against car parts suppliers, which are under investigation for fixing prices for products ranging from thermal systems to seat belts and ball bearings.
U.S. and Japanese antitrust regulators have already levied hefty fines on several parts producers, with more than 10 people jailed in the United States.
