Production of the 7-passenger Ascender ended in February 2006 with the closure of GM's Oklahoma City Assembly plant, leaving Isuzu with the 5-passenger Ascender, built in Moraine, Ohio and the low-selling i-Series as its only retail products. The company sold just 1,504 vehicles in North America in the first two months of 2006. GM ended its equity investment in Isuzu and sold all its shares to Mitsubishi Corporation, Itochu and Mizuho Corporate Bank; both GM and Isuzu claimed the companies would continue their relationship, but there was no word as of April 12, 2006 on the effect this would have on DMAX operations.
