Known issues on the 2021 GLA45 AMG. Five recalls and one owner complaint are recorded for the 2021 GLA45 AMG. The mechanical one concerns the driver's door lock on certain vehicles, where a corroded micro-switch might not register the door opening, so the automatic parking brake or Auto-Park would not apply and the car could roll away; dealers replace the lock. Two campaigns targeted software on certain vehicles that could leave the rearview camera image blank, one through the camera itself and one through an MBUX screen that stayed dark or restarted, putting the car out of step with the federal rear visibility standard. Two more addressed communication module software on certain vehicles that could disable emergency calling or send responders to the wrong location. Door lock, camera and multimedia diagnostics are covered.
