Known issues on the 2018 GLC63 AMG S. Three recalls name certain 2018 GLC63 AMG S vehicles, and the restraint system runs through them.

On certain vehicles equipped with the Audio 20 head unit and automatic child seat recognition, the passenger airbag status could read incorrectly. Separately, NHTSA filed five recalls against certain 2018 AMG GLC63 models, among them a starter cable that could chafe and short, and the 2018 AMG GLC63 models carry 1 engine complaint.
