general problems of the 2002 BMW 3 Series

I opened the passenger door in the morning after the car had been parked overnight. I had a hockey bag with approximately 25 lbs of equipment sitting on the passenger seat which I removed from the car and closed the door. I forgot something and went back to the car, about 40 seconds later, and saw a cloud of white smoke at the ceiling and I opened the door. The car had a strong smell of burning plastic/electronics. Whatever was burning stopped and there was no visible flame. I checked all the electrical switches and all the equipment seemed to work fine and no fuses were blown. The burning seemed to come from the passenger seat heater as there was evidence of the seat cover having smooth marks on the surface (instead of the normal pebble surface) where it might have melted. I'm not sure if the seats are real leather or simulated.

Using key fob to unlock doors, sometimes only driver door unlocks. Sometimes no doors unlock/lock. Interior master lock switch sometimes works sometimes does not. Replaced switch twice. Been in car and unable to unlock any doors to get out of vehicle using electric systems and even manual ie. Door handles. In a non stressful situation, got out by rolling down window and inserting key in driver door to unlock. For panic situations bought a window shatter tool to break windows to get out.

I have intermittent problems on hot days unlocking my car doors. My key button does not always open the door. I have to manually open the door. The real problem is when I'm inside the car, the unlock button does not work, even when I manually pull on the door handles from inside the car, the doors continues to be locked. This creates a very dangerous situation and a major safety hazard for all the passengers because the doors do not open. Once the car is cooler, they start to work again. I'm afraid that if I ever get into a car accident, nobody will be able to get out of the car. There is no BMW recall for failed locks. Please help.
