The 2019 Mercedes-Benz AMG C43 has 12 recalls, the most serious involving a front roof panel that can detach from the vehicle and become a road hazard, along with a software fault that can cause the engine to stall while driving.
On the safety systems side, seatbelt pretensioners on certain coupe and cabriolet models may fail to tighten in a crash, reducing occupant protection. A separate recall covers front seatbelts that may not fully retract, which can discourage regular use. The automatic emergency braking radar system can also become impaired and fail to apply braking when needed. There is also a software fault that can disable electronic stability control without the driver's knowledge, reducing traction in emergency maneuvers.
Several recalls affect visibility and communication. The rearview camera can fail to display an image when reversing due to a software error, and LED headlights on certain vehicles may have been adjusted incorrectly during a prior repair, reducing nighttime visibility. Two related recalls cover the emergency call system, which can either fail to connect to emergency services or dispatch responders to the wrong location after a crash. A loose 12-volt battery mounting bracket can allow the battery to shift in a crash, cutting power to hazard lights and emergency communication systems.
