Three problems related to service brakes have been reported for the 2011 BMW X3. The most recently reported issues are listed below.
The error "chassis stabilization" popped up with multiple lights on the instrument gauge cluster. Steering, acceleration, and braking were effected. After backing out of driveway, made a sharp right turn and warnings appeared. They also happen intermittently during driving, most often in the first 2 minutes of driving.
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. Stopping and re-starting several times. Losing all power, brakes, steering, etc at each instance. Vehicle was placed on a flat bed and taken to sewickley BMW the following day. After almost a week, the car was returned to me. I was told it was an electrical issue. Exactly 2 weeks later the same problems re-occurred. Again I was on an interstate and the lose of control at a high rate of speed could have been a catastrophe if an inexperience driver was behind the wheel. The car was repaired again and this time more work was done. The dealer said that they found a bulletin from BMW that explained this possibility. I saw the BMW info and it understated what actually could or would occur should their systems fail. In my opinion, my life was in severe jeopardy when the failures occurred and had I not been an experienced driver with calm reactions, a fatality is not out of the question. My wife will no longer ride in the vehicle and I have been told to get rid of it ASAP. I reported these incidents to BMW and quite frankly they were totally indifferent to the problem, only saying that the vehicle is out of warranty and they have no obligation to do anything for me. In my opinion, this is a major problem waiting to explode. BMW is ignoring the issue and someone will die.
I pulled my car into my flat garage, placed it in park, turned it off and went into the house. 1 hour later it had rolled out into the yard. It was off and in park. It was towed and evaluated by a BMW "expert" who determined there was nothing wrong. They said the car could not have been left in neutral and could not have been left on and then gone off. They had no explanation for the failure to hold the park position and that it was safe to drive!!! my insurance covered the $3200 damage and car rental. In this regard I made probably 200 phone calls between the insurance , dealer, BMW corporate, etc. It took 9 weeks to resolve and repair.
