One problem related to door latch has been reported for the 2002 BMW 745. The most recently reported issues are listed below.
There have been many occasions when the doors on my 2002 BMW 745 have frozen closed after driving to a destination. This could have resulted in a serious problem had we been in an accident and not been able to exit the car. Myself and my passengers could have been trapped in the car. I have also had occasion when the door would not latch after driving to a destination. I have made numerous complaints to the dealer and have been told there is no solution to this problem other than spraying the door latch with silicone. This only works for a short while and is ineffective if very cold temperatures follow within a day or two of rain or having the car washed.
