cars, as the engine sends air to the brake booster.
The recall is one of the biggest involving electric vehicles.
In August 2012, Fisker Automotive recalled 2,400 Karma plug-in hybrids to repair a faulty cooling fan unit that was the cause of a vehicle fire.
In Jan 2012, General Motors offered to fix the battery pack for the 8,000 Volt plug-in hybrids to eliminate the risk of a fire being triggered days after a crash.
Sales of electric cars make up only a small percentage of the overall autos market.
In 2012, Nissan sold 9,819 of its world's best-selling EV, the Leaf, in the United States, where 14.5 million vehicles were sold in total.
Mitsubishi Motors has sold or exported a total of around 27,200 i-MiEVs since it first went on sale in July 2009.
The recall comes a month after Mitsubishi Motor was inspected by Japan's Transport Ministry, which said the automaker inappropriately reported about recalls involving mini cars.
Mitsubishi Motors has been mired in a string of recall scandals including in 2000, when an insider's tip revealed the automaker had been hiding customer complaints illegally for over two decades.
