Known issues on the 2021 GLA35 AMG. The federal record holds five recalls for certain 2021 GLA35 AMG vehicles, and most trace back to software. One is mechanical: on certain vehicles, a small switch inside the driver's door lock could corrode and miss an open door, so the automatic parking brake or Auto-Park might not apply and the SUV could roll away, which dealers fix by replacing the lock. Another involved the multimedia system on certain vehicles, whose display could stay dark or restart, losing the rearview camera picture. Separately, on certain vehicles, SIM card software in the communication module could drop the network and disable emergency calling. Door lock, parking brake and camera wiring diagrams, procedures and diagnostics are included.
