Owners/service Manual problems of the 2008 BMW 328

Electronic door locks failed to unlock thus trapping myself in the car. No mechanical override exists to manually unlock the doors. I had to roll the window down and climb out through the window. The 4 door sedan has small windows and I hurt myself (pulled muscles and joints) climbing out. If the windows failed (they did not), I would have had to break the windows and then climb out. Elderly or handicapped occupants would not be able to get out! any power failure will trap occupants since no mechanical override exists!.

I am unable to open/unlock the driver's side door. Other doors are fine but I would be trapped in case of fire or accident. Door does unlock through manual key (not fob).

The potential safety hazard reported in this complaint takes place when the passengers cannot exit the car by opening the doors, getting trapped inside the car. It will worsen to a critical level when this failure happens with passengers with limited mobility inside the car or in case there is a baby sitting in a child seat installed in the rear seat. When the described failure mode happens, all passengers will need to exit the vehicle through the sun roof (if available) or through the windows. In case of fire this could be a lethal safety hazard for all passengers. And in case of voluminous persons sitting in seats others than the driver's seat, it will be very difficult for them to exit the vehicle. How the failure happened: after driving for aprox. 10 minutes and having parked, the doors of the car did not unlock. They did not unlock either using the fob, neither the door handle of the driver's door nor the unlock button in the central dashboard. The only way to get out of the vehicle was through the sun roof or climbing out the window. After several attempts the driver's door finally unlock and could be opened. Once outside the car, I could lock and unlock the driver's door (but not any other door) manually with the metal key inside the fob. The other passenger had to exit the car through the driver's door. I have been to a BMW dealership and I made an appointment to repair it. The root cause of the issue seems to be a blown fuse due to over current in one of the actuators of one of the doors. The effect is that the passengers cannot come out of the car as there is not any manual mechanism to unlock. There is other complaints in NHTSA about the same issue (for example NHTSA id number: 10459121). I recommend that NHTSA conducts a safety investigation about this potential safety risk on this or any other affected model.
