Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering powertrain on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
A manufacturing defect in a bearing of the electronic drive unit could result in bearing damage. This is caused by an unusual acoustic signal in the area of the drive unit. The bearing could fail completely at a later stage, which will be displayed to you by means of a red Check Control message. In this case, the driver is asked to call BMW Roadside Assistance.

At that moment, something occurred that caused the car to speed over the parking curb, across a pedestrian sidewalk and struck a…
