Recurring system failures: my vehicle has exhibited intermittent and unpredictable system malfunctions, including engine stalling, braking issues, and electronic system failures. These pose serious safety risks and have made driving increasingly hazardous. Continual tire pressure monitor reset light warning after reset 100 % measurement successful. Rebalance all tires light reappear distant same spots.
Sunroof exploded, glass shards everywhere. This has to be a manufacturer defect.
The vehicle throws a “passenger restraint system malfunction” every 5 minutes while driving. Based on discussions on BMW forums, this is a common issue among several models of BMW. The issue seems to be caused by loose wires/sensors beneath a he passenger seat.
According to BMW literature, under appropriate conditions, the driver is to be alerted by means of vibrations in the steering wheel of either unintentional lane changes or vehicles in the driver's blind spot while signaling a turn. In my 540i, I can detect no steering wheel vibrations at all with the �light� and �medium� vibration settings. With the �strong� setting, I can sometimes detect a very slight vibration � if I pay close attention � but it is very hard to distinguish from road surface feedback. In any event, the "intelligent safety system" is not alerting the driver of potentially hazardous conditions as it is supposed to do. This results in unsafe driving conditions. My dealer and BMW have been unable to resolve this issue.
The rear cross-traffic/pedestrian alert system is dysfunctional. I have had two other vehicles with this feature and am quite familiar with it. This vehicle is incapable of effectively detecting and warning of approaching rear traffic and/or (and worse) pedestrians. Repeated efforts to have my BMW dealer address it have been fruitless. BMW USA simply circles me back to the same dealer who is unable or unwilling to address the problem. The net result is "safely technology" that, if relied upon, has the potential to do more harm than good.
