All because one key component is lacking. This was bound to happen eventually to another major General Motors production facility and now it has. GM has confirmed to Automotive News its Lansing Grand River Assembly plant in Michigan will be idled beginning this Monday through the end of this month, if not longer. The reason? A lack of semiconductor chips, a crisis that continues to plague the auto industry at large, with the exception of Toyota. Like other affected automakers, GM is using its existing semiconductor chip supply for highly profitable and extremely popular vehicles, mainly trucks and SUVs. Slow sellers and some newer models are being sacrificed instead, including the Chevy Camaro, Malibu, Cadillac CT4 and CT5, all of which are built at Lansing Grand River.
