2003 BMW 325I 4-door sedan - problem: Electric door locks will not always unlock with key fob. Persistent with colder ambient temperatures (less than 65 degrees F). I can unlock drivers door with key, but no other doors unlock. Issue: The door locks double-lock meaning when doors are locked, they can't be opened from outside or inside (by pulling on handle). The only door that unlocks with interior handle pull is drivers door. If vehicle is in an accident my passengers will not be able to unlock their doors to exit vehicle! they are basically locked inside. This is a big safety issue, especially if there is a danger of fire or some other event that necessitates quickly exiting the car. My research: I've basically narrowed it to the GM5 module that controls the door locking and unlocking. This module controls some other vehicle functions as well. The door locking function works great, but unlocking is sporadic with ambient temperature fluctuations. Opinion: There should be an investigation opened on this issue. Reading several BMW user forums this appears to be a common problem across many vehicle years. The double-locking door locks are a nice anti-theft feature, but are dangerous if the system malfunctions. BMW must acknowledge a defect is present in the GM5 module and take appropriate action.
