Today, March 27th, Mitsubishi asked 4,000 owners of its EVs and hybrids to avoid charging their cars due to an investigation into overheating batteries.

Two incidents triggered this investigation: a fire which started due to an overheating unit in a plant which manufactures the MiEV electric vehicle and the melting of a hybrid Outlander lithium battery pack which was due for sales earlier this month. The plug-in model has been launched in January and since then the automaker sold 4,000 units.

“We suspect the two cases were caused by a change in the production line of the battery supplier. We asked its owners not to charge the batteries until the cause of the incident can be confirmed,” a company spokeswoman said.

No one was injured during these two incidents and the company said that it has not received any similar complaints from its customers. The lithium ion battery packs were manufactured by a JV between Mitsubishi Motors, Mitsubishi Corp. and GS Yuasa.

Two months ago GS Yuansa drew attention of the entire world when a battery from a Japan Airlines 787 caught fire, forcing pilots to make an emergency landing. This incident led to the worldwide grounding of Boeing’s next generation aircraft. The company was not found guilty for the problem.
