Known issues on the 2020 CLA45 AMG. NHTSA lists seven recalls for the 2020 CLA45 AMG. One covered 7 certain vehicles equipped with 4-cylinder gasoline engines that may have received the wrong spark plugs, which could break apart and damage the engine enough to stall it. On certain vehicles a corroded switch inside the driver door lock could miss an open door, so the automatic parking brake would not set and the car could roll away; dealers replace the lock. Certain cars also may have lacked the gauge for checking rear brake pad wear, and on certain vehicles two campaigns fixed software that could blank the rearview camera. Ignition, brake and door lock procedures, torque values, wiring diagrams and diagnostics cover these systems.
