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 2018 Mercedes-Benz AMG GLC43 has 10 recalls, the most serious involving the driver-side airbag inflator, which can rupture during deployment and send sharp metal fragments into the cabin, potentially causing serious injury or death.
A separate airbag recall covers an inadvertent deployment risk where the driver airbag can fire without a crash. The passenger-side airbag warning display can also show the airbag as active when it is not, leaving a front-seat passenger unaware they have no airbag protection in a crash. On the restraint side, the rear outboard seatbelt latch plates can retract into the door panel trim, making the belts unusable for rear passengers.
Several recalls involve panels separating from the vehicle while driving. The front roof panel between the windshield and panoramic sunroof can detach and become a road hazard, and prior repair attempts on some vehicles did not fully resolve this issue. The panoramic sunroof's plastic side and front panels can also separate from the vehicle. On vehicles equipped with LED headlights, the front turn signals may glow pink or violet rather than the correct amber, making them harder for other drivers to recognize. The automatic crash notification system can direct emergency responders to the wrong location after a collision.
