Ignition Module problems of the 2004 BMW 530

There was a burnt plastic odor, shortly after that there was smoke coming out of the trunk. There was a cable connected to the battery that come loose, which caused the power module to burnt out. There was power outage throughout the car, the noticeable ones included: the radio (the screen was completely black and there was no sound); the car alarm; and the bing alerting sounds that goes off when key is in ignition, seatbelts are not strapped,etc. Were not working. My technician change the power module then he noticed that the cable that came loose only disconnects when there is a car accidents as a precaution, just the same way the airbags deflate. He advised that it was a manufacturing defect that could lead to an explosion. When I informed BMW center about this problem they said it had nothing to do with a defect that it was "wear and tear", but then again they didn't bother to diagnose it, they didn't even bother to take a look at it!.
