After a couple more potential battery short-circuit incidents with its Outlander plug-in hybrid, Mitsubishi is extending its hold back of further shipments.

As we previously reported, the company chronicled a couple meltdowns, one resulting in a minor fire. It has not been shipping them since late March.

Presently the vehicles are distributed only in Japan although they had been due to go to Europe in July, and the U.S. next year.

Concerns include that one of two battery suppliers, GS Yuasa, also makes batteries for the Boeing 787 Dreamliner which had been grounded due to battery safety concerns.

Aside from the previous two incident reports, Mitsubishi’s Ryugo Nakao, managing director, noted two more – one in which an Outlander plug-in battery short circuited, and another where abnormal voltage was detected.

Following one battery incident, Mitsubishi is investigating whether a test battery that short circuited and melted might have been impacted too hard when placed on a machine to test it.

The company has not otherwise ascertained the cause, and although it has said it would attempt to wrap it up by April, it now says it will refrain from selling the car until it corrects the cause.

The plug-in hybrid version of the new Outlander has outsold the non-hybrid version in Japan which is a noteworthy accomplishment.

To date Mitsubishi has sold 4,000 and taken orders for as many more.
