I was driving at about 65 mph on a highway uphill, engine completely stalled, no power, got a message "drive-train malfunction, no maximum output, drive moderately". I was surrounded by cars/semi trucks, very dangerous situation. Managed to pull over on the should. Could not restart car, got a message "automatic start/stop deactivated: Engine will not start automatically. Press the start/stop button to start the engine." About 30 mins after engine stalled, I finally restarted the car. Continued to drive on the highway for about 10 miles @ 60-65 mph. At a local street, as I slowed down to approach a traffic light, engine stalled again, no power, car stopped in the middle of road, got the two same messages, could not start car. About 30 mins after engine stalled, I finally started the car.

Last month my car was approximately 52,200 miles (out of warranty) and leaking oil all over my driveway and under the hood. It cost me $1570 to fix by replacing the fiter casing. Luckily that the oil leak was in my driveway. What if I was on the freeway? this is totally unsafe car to drive. The local shop told me that the filter housing (2012 version) was made of plastic and the current BMW one 2014 is made of metal. The local shop told me to call BMW if there is any recall for this. So before fixing it local shop, I did call the crevier BMW in santa ana, ca and the service advisor told me that there is no recall for the filter housing and my car was out of warranty. I told the BMW advisor that I cannot believe that a 2012 BMW 528I with 52K miles on it and leaking oil all over the place. The BMW advisor told me that I drove too much. What kind of service is that? and BMW will not cover it. So BMW cannot be driven over 50K miles. I also did call BMW corporate and someone from BMW corporate called me back that and said nothing BMW can do about this. Now I found out because of the oil leak, the alternator is having problem. I want to report this incident so that BMW should be responsible to similar cases of their unsafe cars.

Driving in the hov at approximately 9pm when an alert message "drivetrain malfunction, drive moderately" displays. Car engine immediately cuts out and we have no propulsion. We are unable to move to a safe location and wind up on a narrow shoulder of the lie in NY. Police come and close down 2 lanes to prevent collision (extremely dangerous road conditions). We were unable to start the car or shift it into neutral. Car was towed. BMW notifies us that fuel sensors malfunctioned resulting in us running out of gas even thought the indicator showed we had 1/2 tank. However because we were over the 50,000 mile warranty we would be responsible for replacing.. BMW is looking for us to pay $3,100 to have the fuel sensors replaced. I researched this and found that BMW had issued a recall on its 2011 5 series sedans and 2012 5 series GT for a fuel sensor malfunction that mirrors exactly what happened to us. We purchased our BMW Nov 2011. We strongly believe this fuel sensor defect both in design and functionality is the reason behind what happened to us. Put my family and 6 police patrol men in harms way. Notified BMW that they need to extend their recall to other 2012 5 series sedans given our experience. Felt compelled to notify you as there may be other drivers who will be put in harms way if this problem is not reconciled on all 2012 5 series sedans. We were lucky we were not injured. Someone else might not be.

While driving in metro detroit last night my 2012 BMW 528I xdrive suddenly flashed a "fuel system malfunction" message, lurched and came to a dead stop just past the intersection of novi road and 10 mile. I was two miles from the expressway and my wife and children were with me in the car. Had I made it to I-96 - just two miles up the road - and this happened, we very likely would have been involved in a major accident. Police were called because I was in the middle of the street. The car was electronically locked. I could not put the car in neutral to move it out of the roadway. BMW service finally managed to get the car towed 8 hours later because few tow trucks lacked the equipment needed to move the car without damage. There is no manual override to allow you to put the car in neutral, it can only be accessed by a service tech underneath the car. My service advisor was well aware of the problem. This is a major hazard and huge design flaw. There is no mechanical linkage to either the start/stop button or the shifter. It's all electronically controlled. I shudder to think what would have happened had the car stalled on the interstate. Now I'm stuck with a car I don't feel safe driving.
