Isuzu Motors Ltd. is seeking talks with General Motors Co. to review a joint engine-making factory in the U.S. that may operate at 30 percent capacity next year.

Ending joint production at the Ohio plant "may be an option," Isuzu President Susumu Hosoi said in an interview at the company's headquarters in Tokyo last week. The venture, DMAX Ltd., is 60 percent owned by GM and makes diesel engines for the Detroit-based automaker.

Isuzu, Japan's largest maker of light trucks, would be the latest of several automakers, including Toyota Motor Corp., to abandon ventures with GM after the U.S. carmaker emerged from bankruptcy earlier this year.
