The 2018 Mercedes-Benz AMG GLC63 has 7 recalls, the most serious involving a starter cable that can chafe against the housing, short-circuit, stall the engine, or start a fire.
A roof panel adhesive can also deteriorate and allow the front roof panel to detach at speed, becoming a hazard for other vehicles. On the occupant safety side, rear seat belt latch plates can slip back into the interior trim, making the belts inaccessible to outboard rear passengers in a crash. The front passenger airbag may deploy late in a crash for unbelted occupants, and the passenger seat sensor can incorrectly show the front airbag as active when it will not actually deploy, leaving a passenger unaware they have no airbag protection. The automatic crash notification system can send emergency responders to the wrong location after a collision. There is also a concern with the eCall system failing to accurately report the vehicle's position, which delays emergency response when it is needed most.
