The 2021 Mercedes-Benz AMG C63 S has 4 recalls, the most serious involving a fuel pump that can shut down without warning, cutting engine power while driving and raising the risk of a crash.
This vehicle is a cabriolet, and two recalls are specific to that body style. The rear headrests may be incorrectly mounted to the seatbacks and can move or pull free during a crash, leaving rear passengers without proper head and neck support when they need it most. On the restraint side, the seatbelt pretensioners may not function correctly in a crash, meaning the belts may fail to pull occupants firmly back into the seat at the moment of impact. There is also a software issue that can cause the rearview camera image to fail to appear when backing up, leaving the driver with a blank screen and reduced visibility behind the vehicle.
