The plant that assembles Chrysler’s Jeep Wrangler near Toledo, Ohio sprawls across four buildings, but Chrysler occupies only one of them. The others house three of the troubled carmaker’s suppliers. South Korea’s Hyundai Mobis builds the Wrangler’s chassis, while Kuka, a German maker of robots and welding machines, puts together the body. The facility’s paint shop is operated by Magna International of Canada, with Chrysler responsible only for the vehicle’s final assembly.
