2021 BMW 330i Vehicle Not Securing When Locked

Symptoms

Owners of affected 2021 BMW models, including the 330i, may observe a specific issue when attempting to lock their vehicle using the remote control. The primary symptom is that while the doors physically lock, the vehicle does not become fully secured. This is indicated by "The alarm system is not activated". Additionally, if the side mirror folding function is enabled, "The side mirrors (when the function is activated) do not fold in".
