Known issues on the 2020 C43 AMG. Nine recalls appear for this model year, and one stands out mechanically. Certain 2020 C43 AMG vehicles equipped with a gasoline engine could have debris caught between the fuel rail and the injectors during assembly, letting fuel escape near hot engine or exhaust parts and raising the risk of fire; dealers replaced the rail and injectors. Other campaigns addressed certain vehicles with rearview camera software that could blank the backup image, and certain vehicles with communication module software that could knock out emergency calling. Among 12 owner complaints, the power train leads with four and back over prevention follows with two. Fuel injection procedures, camera diagnostics and powertrain specifications with torque values are covered in the manual.
