My 2007 328I has been in the service department a total of 4 times (that I have paperwork on, it might be more). I have had major mechanical problems with the most recent being electrical. My key will not open any of the doors, I have to use the valet key to get inside. Once I get inside the button on the dash that opens and locks the doors was unresponsive as well. When this started the drivers side mirror also became unresponsive and would not adjust, I can't adjust it to see the road and have almost been in 2 accidents. The same day the air conditioning, which I had set on 60, turned itself to 84 blowing full blast. That is actually the second time this year that the air conditioning has automatically turned to the heater. Short list of other issues: Recurrent break squeaking, oil sensor and engine harness wires breaking, and problems accelerating. The computer software malfunctioned as well (another electrical issue which was causing the car to malfunction). After the brake pads & sensors were replaced, the brakes sound the same to this day, horribly squeaky almost grinding. The front driver & passenger windows have a mysterious electrical malfunction. They will cease to go up or down. I hold the window button in the "up" position, the window will roll up an inch then stop. I will have to do this several more times before the window will go up or down. My car goes in again tomorrow am. This time I even mentioned that if I did have passengers in the vehicle and we had gotten in an accident, or worse yet the car catches on fire, my passengers would be trapped. The service advisor didn't seem to care. I can't drive my friends or family anywhere for fear they will be stuck in the vehicle if an accident occurred. As well, I'm not going to ask my parents, who are in their 50's, to crawl through a window to get in or out of my vehicle. My car has been out of commission for me at least 30 days since I've owned it.
