NHTSA (USA)High Risk

What can fail
The front roof panel between the windshield and panoramic sunroof may have been improperly bonded during a prior repair, causing the panel to detach from the vehicle.
The 2019 Mercedes-Benz AMG GLC63 has 8 recalls, the most serious involving a starter power cable that can chafe against the housing, short-circuit, stall the engine, and potentially start a fire.
Several recalls affect occupant safety in a crash. The front passenger airbag can deploy late for unbelted occupants, and the seatbelt pretensioners along with the pre-crash tensioning system may fail to activate at all, leaving occupants with less protection when it matters most. A separate recall covers the passenger seat sensor, which can incorrectly show the front airbag as active when it is not, meaning a passenger may not realize they have no airbag coverage. On the structural side, a front roof panel on vehicles that received a prior repair may not have been bonded properly and can detach while driving, creating a hazard for other road users. The sun visor airbag warning label on some vehicles is printed in a foreign language, which may leave occupants unaware of front-seat risks for children. Two recalls cover the emergency call system: in one, the system may be disabled entirely and unable to reach emergency services; in the other, it may transmit the wrong location to responders after a crash.
