Some 2017-2020 Continental vehicles built on or before 10-Jan-2020 may exhibit a creak type noise when opening or closing either front door. This may be due to fatigue in the sheet metal of the door in the area of the door check arm. If fatigue is found, a revised door assembly has been released for this concern. The part numbers of these revised door assemblies are GD9Z-5420125-C (left door) and GD9Z-5420124-C (right door).
