Known issues on the 2022 GLA45 AMG. The one recall filed for the 2022 GLA45 AMG ties a small door part to a serious outcome. In certain vehicles, a micro-switch inside the driver's door lock can corrode and stop sensing when the door opens. Without that signal, neither the automatic parking brake nor the Auto-Park function engages on its own, and the vehicle may roll. The repair is a new driver's door lock. For that work the manual gives door trim and lock removal procedures, torque values, the lock and parking brake wiring diagrams, and the diagnostics used to confirm the switch signal.
