The 2021 Mercedes-Benz AMG C63 has 5 recalls, the most serious being a fuel pump that can shut down without warning, cutting drive power and leaving the driver unable to accelerate or maintain speed.
Because this is a cabriolet, two occupant safety recalls are also relevant. The rear headrests may be incorrectly mounted to the seatbacks and can shift or detach during a crash, reducing the protection they would otherwise provide to rear passengers. The seatbelt pretensioners on certain vehicles may also not perform as intended in a crash, meaning the belts may not pull occupants firmly into their seats at the moment of impact when it matters most. On the visibility side, a software error can prevent the rearview camera image from appearing on the display when backing up, leaving the driver without the expected view behind the vehicle. There is also a communication system concern: the automatic emergency call feature can be disabled, meaning the vehicle would be unable to contact emergency services automatically after a collision, which could delay a response.
