The Mitsubishi announced that it has identified the problem showed the batteries of hybrid / electric cars, which led to discontinuation of Mitsubishi Outlander PHEV and I-MiEV. The problem was traced to a battery cell which is derived from the supplier of Mitsubishi. The problem occurred in a selection process that was added to the production line in December 2012.
