2011 BMW X3 Electrical system Problems

“Junction box failure. I started having all types of random electrical problems. Wipers come on at random. Door locks, back windows, and turn signals won't work when this happens. I read that this issue was happening in other models, but don't see that the Bmw X3 itself wasn't called out. Had the issue looked at by a mechanic and he said the stored codes were for main junction box failure or no message received from main junction box. It doesn't matter if the vehicle is stationary or in motion, issue still happens. Sometime when I turn off the car, the wipers are still going. …”

“I came outside one morning to find that all my windows were rolled down, the sunroof was rolled completely back, and the doors were unlocked. It had been raining heavily the night before and the interior of the car was completely soaked. The idrive system, radio, and seats were completely unresponsive. Almost every light on the dashboard was on - low tire pressure, ABS, airbag light, parking brake malfunction, cel, oil light, and others. Upon further experimentation, I discovered that the car would open completely if I unwittingly held the unlock key for no more than 3 seconds. …”

“Key fob quit working three days after they put new batteries in it because I stated it didn't seem to be working correctly. By quit working I mean: keyless entry would not work; remote would not unlock or lock doors or tailgate. I had to take the metal key to unlock door. Once inside I had to put key fob next to steering column in order to get it to start. Called dealership service center, the made appointment and brought me loaner car. They stated I'd have it back that evening. Not returned. Then next day I was told it had to be over nighted. …”

“While driving on an interstate road, exiting a tunnel, the x-3 suddenly, without any warning or indicators, lost the power steering and power brakes. The engine lost power and the dash board lite up with a myriad of warnings that made no sense. Then, just as suddenly the entire dash board went dark. The vehicle was extremely difficult to steer and stop. Since I was in fast moving traffic, the situation was scary to say the least. I found a place to pull off and did so. I turned the x-3 off. At restart it seemed ok, but the problem re-occurred again. I was able to finally get to my house. …”

“The passenger restraint system is malfunctioning. This is a common problem that Bmw X3 cars have. We have the sports edition and despite several attempts to fix the problem the sensor in the mat continue to indicate the air bag will not deploy if we have an accident despite how severe that accident is. We have contacted the Bmw dealership and they pretended of knowing nothing about similar complaints or of a recall on the sensor in the seat mat. It will cost us about 1,000 dollars to fix. Yet most to all Bmw owners of the X3 series, especially the sports edition have the same problem.”
