Electrical Failure Problems of BMW 328

A blown fuse caused the door unlocking mechanism to fail, trapping occupants in the car. The doors could not be opened by any means, as the failure also disabled the normal mechanism by which pulling on an interior door handle released the associated lock. The sole exception is that the driver's door could be opened by rolling down the window, and reaching out awkwardly through the window to the exterior door handle with the mechanical auxiliary key. However, the only exit available to backseat passengers was through the windows, assuming the passengers were small enough to fit through them. Neither of these modes of egress would be satisfactory if exit needed to be quick. Fortunately, this particular failure happened to my family while the car was safely parked. In the event of a collision or fire that required rapid evacuation of the vehicle, however, this would be a potentially life threatening situation. Ideally, the locks should be mechanically linked to the door handles so that an electrical failure would not render it impossible to open the doors. Absent that, at least having individual fuses for each lock actuator would leave three functioning doors if one failed.
