The 2021 Mercedes-Benz AMG C43 has 6 recalls, the most serious being a fuel pump that can shut down without warning, cutting drive power while the vehicle is in motion and raising the risk of a crash.
The seatbelt pretensioners on certain vehicles may not perform correctly in a crash, meaning the belts may fail to lock occupants firmly in place when it matters most. On the cabriolet body style specifically, the rear headrests may be incorrectly mounted to the seatbacks and can shift or detach in a collision, reducing the protection they are meant to provide to rear-seat passengers. Two recalls address the automatic emergency call system: one where the system can become disabled entirely and fail to connect to emergency services after a crash, and another where the system may transmit the wrong vehicle location, potentially sending emergency responders to the wrong place. Finally, a software error can prevent the rearview camera image from appearing on the display when reversing, leaving the driver without a view of the area directly behind the vehicle.
