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 2020 Mercedes-Benz AMG C43 has 9 recalls, the most serious involving a roof panel that can detach from the vehicle at speed and a fuel injector leak that can cause an engine fire.
The roof panel issue appears in two related recalls: the adhesive bonding on the front roof panel can deteriorate and allow it to separate, and a prior repair attempt on some vehicles may not have corrected the bonding properly, leaving those vehicles still at risk. On the fuel side, a leak at the fuel injectors near hot engine or exhaust components raises the risk of fire. There are also two recalls involving the emergency call system: a software fault can disable the system entirely, and a separate issue can cause it to report the wrong vehicle location, both of which could delay emergency responders after a crash. The rearview camera can fail to display its image due to a software error, reducing rear visibility when reversing. LED headlights on some vehicles may have been set to an incorrect angle during a prior repair, which can reduce nighttime road illumination. The front seatbelts may not fully retract after use, which can make them awkward enough that an occupant chooses not to wear one.
