Known issues on the 2023 GLA45 AMG. NHTSA lists a single recall for this year, concerning the risk of a rollaway. On certain 2023 GLA45 AMG vehicles, a small switch inside the driver-side door latch can corrode, leaving the car unaware that the door is open, so neither the parking brake nor Auto-Park engages on its own. Dealers are replacing the driver's door lock. Anyone doing that job will find the door panel removal steps, lock mechanism service, parking brake diagnostics, torque values and wiring diagrams in the manual.
