Volkswagen, meanwhile, hasn't commented on the situation. This move is just the latest in the long-running drama between the two automakers. Just last month, Suzuki filed a notice of breach urging Volkswagen to take remedial action in order to be within the bounds of the original agreement. Volkswagen has been characteristically tight-lipped about whatever turmoil has brewed between the two companies, preferring to reiterate that it is committed to the union.
As part of the announcement, Suzuki said that it seeks the return of the 19.89 percent stake that Volkswagen currently owns in the Japanese automaker through arbitration. Volkswagen purchased the shares for $2.5 billion in 2009.
