Drivetrain malfunction warning - appears and reduces speed at any time of driving - this could cause severe accidents due to loss of power/performance. This warning is engaged at anytime w/O warning. Software update for vehicle should be free of charge as this impacts loss of power. When taking it to auto mechanic, no codes are found and no engine light or fault code. Researching all F56 forum, seems like this has been common complaint. Even though the warning comes on and tells you to drive carefully (slow down). You are still in a high density traffic or freeway that does not allow you enough time to pull on the side. The software should be available to consumer as this impacts the speed of the current driving condition (which is not obvious to other drivers). If it was a flat tire, or smoke coming out of the hood.. this is visible. Mechanics cannot figure out the issue due to a "general / no details" to the specific issue. Therefore, the older software for this model and year should be considered a recall for hazardous driving. Furthermore, software updates should be notified to all consumers and detailing the items that the software will be changing. There is no communication or even on their website to show updates and needs for it. This is a problem if it has anything to do with engine and powertrain.
