2021 Jeep Grand Cherokee MANUFACTURING (USA Car Factory) Proudly building the all-new Jeep Grand Cherokee L in the Motor City. The all-new 2021 Jeep Grand Cherokee L is built at the new Detroit Assembly Complex – Mack plant, the city’s first new manufacturing facility in three decades. Stellantis invested $1.6 billion to build an 800,000-square-foot paint shop and convert the two original Mack Avenue engine plants into an entirely new assembly site. The investment also added 3,850 new jobs to support production of the first ever three-row Jeep Grand Cherokee, as well as the new two-row version and future electrified models. #bestmidsizesuv #carfactory #carplant
