Nissan is recalling nearly 320,000 vehicles in Japan to fix defective coating in an electronic power unit that could cause a short circuit and fire in the worst case scenario.

Reuters said the recall covered six models including the Serena minivan plus minivans and vans manufactured for Suzuki and Mitsubishi between February 2010 and September 2014.

There were eight reports of fires from the defect, a filing with the transport ministry showed.

The recall does not affect vehicles sold outside Japan, a Nissan spokesman told the news agency.
