The 2018 Mercedes-Benz AMG C63 has 10 recalls, the most serious being a driver airbag that can deploy without warning, raising the risk of injury and loss of vehicle control.
A steering rack defect can prevent the rear-wheel-drive variants from being steered properly, and on cabriolet body styles, trim along the rear beltline can separate from the vehicle and become a road hazard. Two recalls address body panels that can detach: the front roof panel between the windshield and sunroof may not be bonded securely and can come loose, and separately, the rear window can detach if its bonding is incorrect. Both create hazards for other drivers. On the occupant safety side, the passenger seat occupant classification sensor can incorrectly show the front airbag as active when it is not, leaving a passenger unaware that the airbag will not deploy in a crash. Seatbacks on certain models may also fail to lock properly and can fold forward in a crash. The front seatbelts may not fully retract, which can discourage use. There is also an automatic crash notification system that can send emergency responders to the wrong location after a collision.
