The 2019 Mercedes-Benz AMG GLC63S has 4 recalls, the most serious involving the restraint system: the front passenger airbag can deploy late in a crash, and the seatbelt pretensioners along with the pre-crash tensioning system may fail to activate at all.
A related airbag concern involves the passenger seat sensor, which can incorrectly show the passenger airbag as active when it is not, leaving an occupant unaware that the airbag will not deploy if a crash occurs. There is also a labeling issue: the passenger-side sun visor may carry airbag warning labels printed in a foreign language, making the child safety warnings unreadable to most owners.
